   I wonder what the easiest way to generate 4:3 NTSC video is?

     @foone Speaking from experience? A Raspberry Pi 1 or 2 with an RCA composite and 3.5mm-to-RCA cable, or a 3 with a TRRS-to-RCA

     @philpem oh did they change the connector for pi 3? I thought they all used the same thing

   • philpem (philpem@digipres.club)'s status on Friday, 29-Dec-2023 08:30:37 JST philpem

     in reply to

     @foone yeah, the 3 puts the audio and video onto a 3.5mm TRRS jack, you need an old 90s camcorder AV cable to break it out. Or you could solder to the board if you didn't have one.
     The 1B and 2B had a yellow RCA jack for composite and a 3.5mm TRS for audio.
     fair warning, the composite out defaults to PAL, you'll want to mod the config.txt to force NTSC and forcibly enable composite.

     the only thing harder than generating good 4:3 NTSC video is taking a picture of the CRT afterwards

     @philpem oh, okay. I was misremembering how that went. I thought they were on TRRS since 2, and 1 was RCA

     This is using a HDMI2AV "up"scaler.

     I'm not sure how 4:3 the output is. it might be outputting a 1280x720 signal and this screen is just cropping it

     I may try switching to a raspi.
     I've avoided using raspis for this sort of thing before because I've had such bad results for them in the past, since they're underpowered CPU/GPU-wise.

     Though I guess if I'm outputting 4:3 video I could always pre-process my video to 640x480 and into a format that requires minimal processing. maybe huffyuv+pcm

   • philpem (philpem@digipres.club)'s status on Friday, 29-Dec-2023 08:53:48 JST philpem

     in reply to

     @foone what are you wanting to output from them? they have hardware decoders for a bunch of codecs. I vaguely recall MPEG2 and VC1 need a licence code (or other means) but MPEG4 was standard. Later Pi's don't have MPEG2 or VC1 at all.

     If you're wanting lossless - yeah, Huffyuv is probably the way to go. but you'll have a YUV -> RGB -> YUV conversion which might introduce some quality loss.

   • philpem (philpem@digipres.club)'s status on Friday, 29-Dec-2023 08:54:53 JST philpem

     in reply to

     @foone If it was outputting 16:9 and the TV couldn't decode WSS (or the converter didn't put a WSS tag in the VBI), you'd get a horizontally squashed picture.
     the cropping may be normal overscan.

     edit: also, hah, 720p to NTSC upscaler, that's a hoot.

     also I wonder if there's any modern tools for doing pan & scan editing. I've got 16:9 video I need to display on 4:3, but just cropping or letterboxing it will be less than ideal.

     I guess any full editing suite could do it, but it seems the kind of thing that could have a specialized tool for it

     @foone In that case encoding to h264 and playing back with VLC is probably the way to go. you could even stream over UDP if you needed to.

     anyway for now I've just resized+cropped a 16:9 1080p video down to 4:3 640x480.

     it's not exactly pan & scan but it's at least better

     also widescreen is a disease.

     I went looking for 4:3 content on a LEGAL DOWNLOAD site's "classic videos" section and they had a bunch of 80s and 90s videos... all 16:9 content filmed on 35mm that got an updated transfer on DVD/blu-ray

     @foone As always, archive.org is a goldmine for stuff like that. Maybe not 1980s and 1990s, but there should be plenty of earlier stuff. I grabbed "The Man in the White Suit" from there the other week.

     okay pre-processing my video to scale+crop it to 640x480 really helped, but I can't be sure if my HDMI2AV scaler is actually outputting 1280x720p and just my display is cropping it to 4:3. but I'm gonna try recording it onto a VHS tape and see how it goes

     So the funny part is that I've encoded the video, installed the os on a spare PC so I can let this run in the background, and managed all the wires and converters so that I can get the signal to the VCR and thus record it...

     But I can't get the VCR to tune into RCA input. There's no button on the front for that, I don't have a remote, and the IR input is disabled because it doesn't like LEDs.

     okay that may be because there's a switch that goes from RS232 to LOCAL to REMOTE.

     you may not expect this, but I think you need to set it to "LOCAL" to get the remote to work

     in reply to

     anyway the final weirdness is that it turns out it was already tuned to "AV IN".

     it's just that there's a physical switch on the front that selects between S-VIDEO in and RCA in. I had it wrong.

     but guess what: I was right! it's outputting a completely useless 720p signal. My VCR completely fails to render that shit.

     yeah I can't get the overscan to make any sense (it's always shoving the output far to the left, with a big black border on the right) and also half the time when I start decoding video, it breaks the USB subsystem and then thinks the spacebar is being held down

     So I got a blu-ray player. I stuck 3 versions of my file onto a USB drive, and tried to load it up.
     file 1, MKV: it says it can't play, because of the "resolution" (640x480)
     file 2, mp4: it "plays", no error, but there's no video. only audio.
     file 3, mpeg: it "plays", but there's no audio, and nothing can be seen except macroblock corruption.

     @moira nah! those were VideoCipher, which work by scrambling the sync signal, causing the distinctive image of the image trying to go five ways at once and the colors being all fucked.

     Macrovision on the other hand is a thing where the front porch of the signal contains a bunch of changing brightness blocks, which fucks up VCR automatic gain control, causing VHS tapes encoded with it to be nearly unwatchable
