LGR – Recording CRT Computer Monitors

[laid back jazz music] [computer buzzing] – Greetings, and welcome to an LGR thing! And today is a bit of a more laid back, unscripted, relaxed type of video while I’m working on more involved things. But this is a topic I’ve
been wanting to talk about for long time and that
is computer CRT monitors and how to record them half decently, which is something I try to do here on LGR as often as I can. I love showing these things, but they can be an absolute
pain to get on video and not look like total garbage. It’s not just eliminating flicker either, it’s all sorts of other issues that I’ve run across over the years that I’ve had to come up with workarounds and mess with my own hardware and software and other kinds of set
ups just to make it work for what I wanna show. And hopefully this will be
informative to you as well. I know I get a lot of questions about how to make these things look okay. So yeah, that’s where
we’re gonna dive into. And, yes, I know that there are
some other videos on YouTube that actually do a really good job of showing how to record
CRTs of various types, but computer CRTs are their own beast. They’re a bit different than
what you would experience on just like a consumer TV set that’s stuck at 60 or
50 hertz or whatever. And yeah this is a — ahh, it’s a
thing man, it’s a thing. Let me preface this by
saying that this will assume that you know a little bit
about how cameras and CRTs work and their relation to each other with refresh rates and shutter speeds. We’ll get into that starting
with the refresh rate, that’s the first main topic I wanna cover, then moiré patterns and the
problems that arise there, color and contrast issues, reproducing what you see in
your eyes versus the camera, reflections, dealing with
those, and audio because, yes, CRTs can be a bit loud
depending on certain situations. So, let’s dive into it. [VCR and old TV sounds] So, starting off with refresh rate. And this is pretty much
the most well-known method of reducing flicker and generally making
CRT imagery look better, and that is syncing, or
getting as close to syncing, the refresh rate of the monitor, the vertical refresh rate that is, and the shutter speed of your camera. And in this case here in NTSC-land that would 60 hertz, or really
59.94, rounded up to 60, and the shutter speed of 60 on my camera. And those more or less make it look good. And if you’re in PAL territory, it’d be of course be 50 hertz
and a shutter speed of 50. And there you go. You can also cut that in half and get some interesting results, sometimes it might be better. But that really is just
the beginning of the story when it comes to these things. If this were like a consumer television, that would pretty much be it ’cause those for the most part just stick to whatever the cycles are
if you’re a power source. But this is… Yeah computer monitors, man,
they’re all over the place. So, for instance, this right here. This is Johnny Castaway, a
screensaver going on Windows 95, and if I press the
buttons of the front here and go into the menus
and look at the status, you’ll see that it’s actually
running at 60.1 hertz. But then if we just move the
mouse and go back to Windows 95 and check that exact same
menu and status again, you’ll see that it’s slightly changed. Now we’ve got 60 hertz exactly. And that’s just one example of
the many different deviations you’re gonna be seeing on computer CRTs, depending on the software, the hardware, the operating system, any
number of other variables, the monitor itself. It’s just gonna be all over the place and that’s something to keep in mind, especially when you’re
looking for a camera or just thinking about filming
these things regardless because, yeah, it’s just
gonna be all over the place. So, sometimes it will not
be anywhere close to 60. Sometimes it’ll be like 70, 72, 75, 85, depending on what the
software demands are, what your settings are, and
all kinds of things. [laughs] Now, if we’re talking just Windows 95 and a lot of the games on there, typically they will stick to whatever your control
panel settings are. So if you have it set to
like the refresh rate of 60, they’ll try to hold to that, especially if they’re like Direct3D games. But you go into DOS and a lot of other
software-rendered things like that, and sometimes it’ll be 70 or whatever. It really helps to have
a monitor that shows you what exactly is going
on at any given time. But you can also just play around with your camera’s shutter settings and see what gets as
close as you possibly can, but a lot of cameras don’t
have that kind of fine-tuning. You can from like 60
shutter speed up to 80, or maybe there’s a 70, but not a 72, and what are you gonna do then? Well, that’s one reason that
I use the cameras that I do for many reasons. But, yeah, I’ve got these
Lumix GH5 series cameras that I use nowadays. This is a GH5S, I’m
filming with a GH5 there, and these have a feature on
there called Synchro Shutter. I believe on Canons it’s called
something like Clear Scan. But it’s on a whole bunch of
different models of cameras these days. But it’s a thing that let’s
you dial in to the 10th, or really in between that
even, the shutter speed, and you can really dial that in there to get to like 60.1 or 72 point whatever. And it’s really helpful
for things like this where it is just a 10th off or
a 10th a little bit different otherwise you’ll see that
rolling line more prominently. And it’s also really useful
for systems that aren’t PCs, like that recent Macintosh
video that I did, the 6100 DOS compatible. Mac OS side of things I
think runs at 67 hertz-ish, 66.7 maybe, I don’t remember. Yeah, it’s a weird thing
and it just looked crazy if I didn’t have that going on. So Synchro Shutter is something that I can’t really do without with filming these CRTs these days, at least if it’s outside
of the norm of 60 hertz. Although you can reduce
it through software depending on your editing suite. I use Adobe Premiere Pro, and there’s some various things that kind of reduce flickering on there. But the one that I use the
most is actually a plugin. It’s a paid plugin called Flicker Free, and that does a great job
of eliminating CRT flicker. It was made for reducing
flicker in time lapse video and stuff like that, but
works great with CRTs. And also for older LCDs, especially those with older CFL or fluorescent lighting behind them, the backlighting, that can flicker regardless of what the actual refresh
rate is on the display itself. The lighting behind the panel
is just different, [laughs] so that plugin helps. So the next big area of concern, and perhaps an even bigger
one than refresh rate, at least for me, is the moiré
pattern problem, or “Mwar” I’m gonna say “moiré” ’cause
it sounds less silly. But anyway, moiré. It’s like an overlaying pattern that’s just conflicting
with the camera sensor and it’s caused by really a
couple of different things, usually like the aperture grille, or the shadow mask,
or whatever. There’s like this pattern that
overlays on top of the image and looks terrible. And if it’s ingrained in your footage, you pretty much just stuck with it. You can alleviate it a little bit in post, but for the most part it’s just in there. And I think it looks terrible. In fact, it bothers me way
more than flicker does. For whatever reason, it just
hits my brain a certain way, I’m like [groans] And unfortunately, it’s
ended up in a lot of my shots because I just wasn’t
paying enough attention and was just sort of
trusting what I saw visually or not looking close enough
on the viewfinder of my camera or the screen that was on the back of it or anything like that. And it became even more of a problem when I really upgraded to better
4K cameras a few years ago, especially the Lumix
GH5, the original GH5. It was really exacerbated on that because of how crisp
and sharp the image was. While that was great for certain shots, I mean, it made a lot
of things look amazing when I recorded it, it made the moiré
pattern effect way worse. And it was really hard to dial that in and get it correctly, I don’t
know, appearing correctly. [laughs] So, what did I do about it? Well, I tried all sorts
of different things when I had the GH5, and that was… I mean, we’ll see, really the
first most obvious thing to do is just focus the camera
a little bit differently. And that usually means getting
it slightly out of focus. So you can eliminate that by
getting that aperture grille or the shadow mask or
whatever is on your CRT slightly out of focus so
that it’s not so sharp on the image on screen. And that will usually
get rid of the effect. Another thing you can do is just mess with your aperture settings
and make it really wide so that it’s not such a
shallow depth of field. And that way you’re not
getting weird bits of moiré in the middle of your image, usually diagonally if
you’re shooting at an angle. And another thing to do is just
mess around with the angles. If you’re shooting at an angle like this, then it can really cause that pattern to emerge more obviously, and then it’s gonna be stuck
in your footage and it sucks. Shooting directly straight on will fix that problem a lot of times, but then you’re just stuck
with a boring kind of shot of just looking directly at a CRT. And a lot of times I don’t wanna do that ’cause I’m showing other bits
of hardware or me in the shot or something like that. So you have to compensate
with those other methods to get it looking half decent and try to eliminate that pattern. Even then it’s not perfect. There’s almost always gonna be that with certain cameras, and
certain angles and situations depending on how you’re focusing. Another thing that I’ve tried is actually using different
diffusion filters, like this one right here is a
Soft/FX 2 something or other. I’ve tried probably 10 of these, I don’t like how any of them look. They do eliminate the
pattern or decrease it on certain sharper cameras like the GH5, but it makes everything soft. And I’d rather just have a
portion of the image softer and you can do that in post, so I just don’t even do that. One thing that made a
huge difference though was completely stopping
using this camera anyway. And I upgraded the GH5S
for multiple reasons, but one of the biggest was because it has a built-in optical low pass
filter in the hardware. And that means effectively
that it is putting, well, a filter [chuckles] in
your footage no matter what. You can’t turn it on or off, like it’s not even on the
options of the camera. I don’t even know if they
advertise it, but it has it. And it makes your image slightly softer, but in a way that I think is pretty smart, and honestly I think the footage
looks way better overall. That optical low pass, man. I didn’t even know that was a thing that a lot of cameras were
going without these days, like the original GH5. So if you can find a camera
with an OLPS in there, it’s awesome. Yeah, that’s pretty much that. Again, you really just kind
of mess around with angles and placement of your camera
and lights and everything else just to make sure that it’s
all coming together properly. And also don’t rely too
much on the smaller screen on the back of your camera if
that’s normally what you use. I’ve started using an external
monitor because of this. Because sometimes it’ll look
great in that little screen on the back of your camera, and then when you get the
footage on your computer, you’re like, “Oh, well this, [laughs] “there’s a moiré pattern there and it’s just ruined the whole shot.” And that’s one of those things because of the nature of
the way that pattern works, when you scale it, scaling it down maybe
there’s no pattern at all, but when you scale it up
to like a full-sized image, then you’re gonna be
seeing it very obviously. So, yeah, there’s a lot of
things to mess around with there, but holy crap, be aware of it. I see so many people shoot CRTs and the moiré is there, and
I’m like, “What are you doing?” Is it just me? [chuckles] Does this not anyone else? Anyway, it’s a thing, look out for it. So another thing to consider with CRTs is the color and contrast settings, and brightness and things like that. Just basically making sure
that your CRT looks good in the resulting footage. And I’m gonna throw in
reflections in here as well because if you have a
reflecty, kind of glossy CRT, that can cause some issues. And lighting and things like that, like I have a light right
there and over there. So, that can all wash out
the image on the CRT itself. In fact, if you look at this one that’s behind me right here, here’s how it looks normally if I just don’t touch the footage. I don’t know, it’s not as impressive. The blacks aren’t as
black as they should be, and the whites, and the
highlights and shadows, like everything is just kind of wrong. So I do a lot of adjusting in
post just on the CRT itself, not affecting the entire image. I mean, I color correct
everything, I adjust everything. But the CRT in particular, I put like a little mask around that and feather it and whatnot. And, again, I use Adobe Premiere Pro, so I use the Lumetri Color
plugin that it comes with. And I usually do a few different things depending on the situation, like just adjusting the
contrast, the highlights, the shadows, sometimes
the white and black level, but usually not. And then I mess around with
the actual saturation values of individual colors, especially on a CRT I’ve
noticed that a lot of extremes for like red, green,
and blue, for instance, just don’t look correct,
so I bump those up. And then also lower some to
make sure they’re not too insane like the blues, especially
on a CRT, can look… I don’t know, everything
can have this kind of teal, light blue look to it. Like grays look more light
blue than they should. But, yeah, that’s all
like filters and stuff. The rest I try to get
the best possible image in camera to begin with. And that just comes down
to a lot of experimentation with lighting and angles of
the room, ambiance itself, like if you’re filming a
CRT in a room with sunlight, that’s really easy to screw up. [laughs] Right now it’s dark outside and I’m just using inside lights, so I got more control over it that way. And since we’re kind
of on this whole topic of like lighting and
making sure the colors and everything look good contrast, reflections can do a lot
to degrade the CRT’s image. So one thing that I love using are these little filters here. This is a circular polarizer. It is of course going to, being that it is darkened and such, you’re gonna lose some stops and your image is gonna be darker. But as you can see here, just sort of plopping
it on and off the lens, not only is the CRT looking darker as far as the black levels and whatnot, but everything really is, [laughs] and it eliminates some of the reflections like around the keyboard area where you can see the reflection
on the bottom of the screen or my hands or just all sorts of things. The wood on the table looks better. It’s not picking up so much of that light bouncing off of the whites
on the walls and whatnot. I just like these polarizers. I use them for absolutely every shot that I use or that I make on LGR. Yeah, I’ve got a bunch of these. This is the one in particular. This is… Yeah, I’ll put whatever it
is right along the bottom of the screen here. [laughs] It’s got kind of a long name. But, yeah, circular polarizers, very much recommend those if
you have the light for it. If you don’t, you might not wanna bother. You can make it look good
on a CRT without these, but these definitely help
in reducing reflections and glare and things like that. Now, it’s not gonna get rid
of everything of course. If you’ve got lights directly on your CRT, it’s just gonna be glare
all over the place. And you’re always gonna
see yourself in the screen if you’re filming at a certain angle. Again though, that’s just playing around with like your camera placement and trying to eliminate that in the scene and not worrying about it later on or with filters or anything like that. Although again, there’s
settings in Premiere that I use and adjust the color and everything else. Also, you can tend to get rid
of some of those reflections if you’re decreasing the
highlights and things like that. You just don’t want to ruin the CRT image or make it look unnatural or anything, I mean, unless you want to, but I don’t. So, the final thing I wanna touch on here, or at least for this video
about recording CRTs, is the audio side of things. And, yeah, that is something
to consider in your recordings. Even if you can’t hear it yourself, which is very much possible depending on your hearing situation. A lot of people start to not be able to hear these really high-pitched
frequencies like this, but, yeah, certain CRTs, especially like consumer
television sets and older ones, like this one right here is an IBM-154, that has a horizontal refresh
of around 15 kilohertz, it’s like 15.7 I think
is the frequency range, and that actually equates
to some audio feedback. Actually, if you listen to this, right here I’ve had it filtered out for the rest of the video, now I don’t. [high-pitched frequency] Yeah, [chuckles] let’s
get rid of that now. Typically, I just put this audio filter on every single one of
my videos that have a CRT in this kind of range of
horizontal refresh like that around 15.7 kilohertz. And that just involves lowering something in like a graphic
equalizer or a notch filter or whatever is going to get
rid of that range of audio so that you don’t hear it. Sometimes I add a couple
of passes within Premiere just to make sure that it’s really gone ’cause I don’t trust my own hearing, so I make sure to look
at the levels and stuff on the software. Yeah, another thing to
consider is that other CRTs, like for instance this one right here, makes another sound and that has to do with the components in
there actually aging. Usually it’s around the flyback area. You’ve got like ceramic capacitors and ferrite transformer cores and all sorts of weird things in there that are going bad or slightly off, or something is just making a sound. And it’s a little bit
different from that audio whine that is just inherent to
the horizontal refresh of these older ones like
this or just regular TV sets. So yeah, that’s something
to keep in mind as well. Sometimes I forget about that, and then in the recording
I’m like [yells frustratedly] that noise is overwhelming. But anyway, so those are
two different kind of sounds that I really listen out for with CRTs when I’m going through the footage. And something else to
keep in mind is that, like the other CRTs that
I was showing earlier, those have a horizontal
refresh of around 30 kilohertz. That is typically not audible. In fact, I don’t know
anybody can hear that. You don’t have to bother
with any kind of getting rid of the high-pitched whine
in the footage that way. So audio, it really is
an important aspect. Even if you can’t hear it yourself, it’s just one of those
things that absolutely sucks. You go through all this pain of getting this nice CRT footage
and you put it on YouTube and then you forget about the audio. And somebody’s inevitably like, “I can’t watch this video
because it’s killing my ears “and it hurts.” [laughs] So yeah, just something to keep in mind, as with all these other things. All righty, well that’s
about it for this topic on this video anyway. Of course with things like this there are always more ideas
and solutions to discuss, and I’m sure you’ve got some of your own, if you had any experience
with this kind of thing. If so, let me know in the comments ’cause really half the reason
I wanted to make this video is not only to inform,
but to learn myself. And maybe we can get a discussion going and come up with some new things. I mean, for instance,
like different lenses, and focal lengths, and situations that can
change on the camera itself can change the result on the CRT, especially with a moiré
pattern problem and whatnot. And there’s also things like
etchings and anti-glare filters and things on the front of certain CRTs, or that you can put on there yourself that provide interesting results, or you can even start adjusting
the options on the CRT in terms of the brightness
and contrast and color to help it look a little more
accurate to what your eyes see in the resulting video
once you’ve recorded it. Not have to mess around
with software and filters in post so much. There’s just all sorts of things. I mean, not even mentioning stuff like the whole genlock idea, and other scalers and hardware
adapters and solutions to take one frame rate, or refresh rate, and adjust it to something else. And yeah, man, it’s a
pretty endless topic, so let me know your thoughts and, again, any of your
experiences in the comments. And I hope that you enjoyed this and maybe found it a
bit informative as well. [relaxing jazz music] And if you liked what
you saw then awesome. Perhaps you’d like to check out
some of my other videos here on the channel. I’ve got new stuff going
up every week here in LGR and all kinds of topics, typically retro computer
hardware and software related. But, yeah, whatever
the case may be though, thank you very much for watching.

  2. Kenji S says:

    My first thought when you were discussing the moire issue is that I was unsure if the gh5 had a low pass filter or not lol. My suggestion was to switch to something with a lpf for screen shots (like the gx8 that had a pretty aggressive one from when I owned it)

    Having no lpf is good for some things. Bad for others. In general I'd rather have a lpf and slight softness over dealing with moire removal in post

    I've only once forgotten to run a low-pass audio filter on my videos, and I got comments from my younger viewers right away. I haven't been able to hear the 15.7 kHz CRT whine since my late '30s, so I just have to remember to do it while I'm working on the audio.

    I’ve always hated the CRT high pitch whine wether from a computer monitor or from a TV. Like it’s not something that was that bad but I realized how much it bugged me once I stopped hearing it, if that makes sense. Even if I was in a different room and someone was watching something with no volume I’d still hear the whine, it even lingers for a tiny bit dissipating some time after the monitor is turned off

    Hi Clint!
    I really enjoy watching your videos to see all the fun stuff you have. I haven't had enough success to be able to store even a fraction of all things you show us but it's fun to be able to enjoy a lot of it through your experiences. My family's first PC was the 5170 and I was a little kid at that time and I've really enjoyed your video of that unboxing. I can relate so much to your feelings for the computers and everything related to them. We don't have thrift stores in any way similar to to yours in the US, so fun to watch those episodes too.

  39. Diyanira TBM-Gaming says:

    Wonderful video, Clint! In my day job, I sometimes have to ADD these screen irregularities to match the other monitors surrounding the monitor I did a footage swap with in my shot. It's funny because so often I need to replicate imperfections to sell the realism of things 😆

  40. I'd Rather Watch Paint Dry says:

    Interesting. When I see flicker in videos I have to look way. Hurts my eyes.

  41. Bryan Jones says:

    Damn I'm old. I couldn't hear the monitor sound. Too much loud music, I guess.

  42. Bryan Wilde says:

    What is the game at 6:10 ?

  43. Fuifd Ruohv says:

    Use scan converter & capture card

  44. Евгений Федоровский says:

    This is incredible – you just watch a beautiful video and absolutely do not realize what kind of work was done to make the picture look so … what it is! There are so many little things that are not noticeable individually, but as a whole they give a visible effect. Real art!

    Thanks for the informative video!

  45. Canadian Music Pulse says:

    oh snap wow 😮

  46. Maarten van Heek says:

    I love your screensaver! I remember I could sit hours in front of it just watching it. And changing the clock to Christmas etc to get the holiday specials 🙂

  47. Velral says:

    The amount of work you put in each video makes Lazy Game Reviews "Hard Working Reviews" in my book.
    It's really interesting to see what goes behind the scenes. I think most of us would appreciate more videos like this. 🙂

  48. Robert Losey says:

    Why are you using a camera to record your monitors? I can understand when you are doing a display review. You can keep the camera on you and use a signal splitter to record direct from the computer display output. at some point you are sending a signal to utube that is digital. you do not need to record from the screen. yes you can review the monitor display but your reviews are of the computer and software, not the display. so why???

  49. surject says:

    Where have you been 1987 when I took pictures from KITT Turbo Boosting over STUFF on TV and sold them at school ?! …but then, every other 8y old thought it was real, despite the moiré and scanlines and flicker shades 😉 So, whatever!

  50. EFormance Engineering says:

    I think that the focal length of the lens also plays a role in moire effects. Wider angle lenses will have more trouble with moire patterns than "normal" or telephoto. For the GH5, a normal lens would be about 22mm, lower is wide and higher is telephoto. The Canon 5Dmk2 also has some moire effects that become more noticeable at shorter focal lengths. This information is based on research I've done on my 5Dmk2.

  55. Revive says:

    Never knew why I could always hear those CRTs back in the day. My aunt used to have a tv that wouldn't shut off with the remote and I would walk in and hear it and tell her that the tv is on and shut it off for her.

  56. Adam Lawson says:

    Love your videos! Thanks for making them.

  57. Mysticalzelda says:

    Makes me appreciatie what you make even more

  58. Drink a Beer and Play a Game says:

    This really gives a perspective on just how much work you put into these videos…also I never even noticed Moire before and now I’m sure many videos will be ruined because of it

  59. Pica Delphon says:

    Only reason for a CRT is the Cold Season for a Space Heater…
    Tiss the Season..

  60. Joniden says:

    OMG I REMEMBER THAT SCREEN SAVER! I sometimes would just sit there and watch the guy.

    What was it called?

  61. tom k says:

    So that's why your videos always look so good and high quality

  62. GeraltRCG says:

    This is the most casually scientific video I have seen. Thank you Clint for this discussion and your findings!

  63. Worhan says:

    I adore that screensaver you have there. Used to watch it for hours with my older sis back in the day when I was a kid

  64. Eric Sebastian says:

    Took you long enough to make this video. Very nerdy.

  65. ms3bani says:

    @15:23 there's also 60hz hum. i've unsubscribed from some channels because the creators refused to acknowledge the problem even when i showed them the spectrum analysis showing the single biggest spike at 60hz. https://i.imgur.com/0PY1KxD.png

    how do u find them because there rare to find not crt's crt monitors

  67. The-Mike_D says:

    Geeze you could teach a class on the subject and include the technical side with the software you use step by step. This was a great video.

  68. Fuck You Google says:

    I used to be able to hear the whine from old TV screens and monitors as a kid. I was extremely sensitive to it, in fact. I could tell if someone had a TV on in their house from the street. Now I don't hear it at all.

  69. B Z says:

    do more videos like these! Pretty informative and interesting!

    Cool keyboard. Which brand/model?

  72. LMacNeill says:

    I'm 49, so I can no longer hear the 15.750 kHz horizontal refresh on older computer monitors and CRT televisions, but I can remember when I was a kid being able to hear it. It was especially bad if a computer monitor was on, but didn't have an input signal, because someone had turned off the computer but forgot to turn off the monitor – they'd really crank out a loud whine then. I'd walk around the the computer lab at school and turn off those monitors — I could hear them that well back then, that I could pinpoint from across the room where the noise was coming from. LOL. Definitely can't hear those frequencies any more though. I'm lucky to hear anything over 10kHz, and only then if it's really loud. Too damn many rock concerts in my 20s.

    I have some interest in photography and a huge interest in technology. This satisfied that sweet spot for me today! ^_^

  74. Justin Hall says:

    How is it you haven't reviewed Indianapolis 500 the simulation from 1989?

  75. Wessel Schaart says:

    It is greatly appreciated that you filter out the CRT whine!
    For me it was one of the best days when we replaced the main TV with a LCD.

  76. Gamer Ramble says:

    I'm watching an LCD monitor that displays a camera which is filming a camera which is filming a CRT monitor

  80. Darrark says:

    Watched this whole video and I have zero intention of recording CRT monitors. No regrets

    best ASMR ever

  85. DixieBoy380 says:

    Love the Johnny Castaway screensaver!

  86. iamdarkyoshi says:

    Moire patterns are super irritating for me taking constant photos of LCD screens, I share a lot of images on telegram, who's compression somehow amplifies the pattern… Best fix I've found on cellphones is to focus on the screen, then move the camera back a little to throw the focus off, and snap a photo before it refocuses.

    Thank you LGR for this video, you've inspirated me about some projects about old 90's computers and games, particulary LAN parties. Those computers you have, look awesome, and also recorded image on them. Never seen so good looking images of CRT monitors, it looked almost like real, and colors were shining live, like you are looking at real monitor and DOS games. Felt urgue to join, and play some oldies, like when I see real old computer with DOS game on screen and noone behind. That feeling from your images was like in reality, just sit behind computer and enjoy some oldies.

  91. bruchpilot747 says:

    Moiré happens when the pattern resolution is higher than the sensor resolution, meaning: the monitors pixels are smaller than the camera sensors pixels thus it creates those interferences. (Moiré was part of my bachelor thesis)

    That's the reason why there are low pass filters on sensors to decrease the pattern's resolution before it hit's the sensor. (edit, you mentioned that after I wrote this)

  92. Anders Öhlund says:

    Some clarification.

    Shutter speed is not Framerate
    Framerate of the camera is measured in fps and shutter speed is measured in fractions of a second. 1/60 shutter speed and 60 fps framerate would mean the shutter is open for the entire frame (shutter angle 360 deg) which is probably the most important thing. Most cameras will default to something like 180 degrees shutter angle 1/(2xframerate) seconds shutter speed and that is why you get things like half the screen being dim

  93. Apocalyptico100 says:

    I'm never going to record any CRT, but I really enjoyed the video

  94. Sapok Biki says:

    Yo Clint… Please do review for Sims 4 newest expansion pack, Discover University… You know, I will not buy from EA, unless it's a "YES" from you. 😑

  95. Nya Bowman says:

    Waiting till you review university next 😁

  96. Adrienne Shepard says:

    When the grid is aligned with another behind, that's a Moiré…

  97. Sofronio says:

    This episode is packed with content. I would like very much to hear from you talking about sound recording. Because your videos have a very good audio.

  98. Daniel Bergquist says:

    I've shot stills of screens. One thing I find helps a lot, regardless of the screen type, is to make sure the screen brightness matches the ambient brightness of its surroundings. For example, the display should be about as bright as its off-white bezels. This will probably make the screen look pretty dark to your eyes since we're used to the displays being brighter than their surroundings, but it really helps the camera out.

  99. David Miller says:

    wanna have some fun? buy plastic sheets with a dot per inch that is the same as your graphics settings, place it on your monitor then turn it while it's on the screen 90 degrees left or right. I used to have to use the technique to remove moire from images before burning plates to use on an offset press (especially 4 color work).
