Render AVI videos with NTSC filter and 768x672 resolution

I'm planning to add some SNES game videos to Youtube, but would like to use NTSC filter for additional retro feeling. Youtube supports 1280x720 resolution, so something like 768x672 resolution would be nice. Stretching to the correct aspect ratio (1:33) can be done elsewhere. I have tested with 896x672 resolution and NTSC by taking a screenshot and uploading a still image video on Youtube. In my opinion, it looks a lot better than "crisp pixels" especially for 1280x720

Don't do it. Youtube videos are blurry enough without TV artifacts.

Sorry for OT but I can't work out in my head how that's correct ratio for anything, in my mind that means e.g. 10*330 pixels? What am I missing?

And the NTSC filter uses 4:3 ratio by default so no further stretching should be necessary, right?

No. They load too slow.

Maybe he meant 1.33.

You can also watch videos in HQ, which is a huge step up from the standard stuff.

I don't know why people like to stretch the crap out of videos that were meant for old 320x240. I prefer to keep video game things in multiples of the original resolution if possible, even if it means black bars on the sides.

I guess. Thanks.

Sometimes even adding &fmt=18 to the URL on certain videos doesn't do anything.

Yeah, that happens if the original video wasn't that great of a quality to begin with.

Yes. I meant 1.33:1 aspect ratio, but from some reason I typed 1:33

AFAIK, 256x224 is the original resolution for SNES most of the time. Many games are designed for 4:3 stretch what old TVs automatically do because pixels are not squares there. They are horizontally larger so I try to mimic that effect. There is some games like Kirby's Dreamland 3 which looks right (for my eyes at least) without stretching.

NTSC filter produces visible scanlines which is the default expected result at the time, when SNES games were made. That is why I multiple the resolution so that Youtube doesn't screw the lines with its own resize. It still looks good for my eyes, better than any other solution. Probably because I have spent my childhood with these old games and old TV was my primary display.

You could use Fraps.

kaappikello · Post by **kaappikello** » Fri Jun 19, 2009 5:37 pm

I have tried Fraps 2.9.8, but it doesn't work at all. Actually it locks my computer after some time and have to reboot, if used with ZSNES

camtasia, canstudio, hypercam, ... anything else.

Other than that, could it possibly be applied as a postprocessing effect? I don't imagine someone's made such a thing, but if you can code, you could maybe create a directshow filter for it.

I'd say don't bother. I'd hate to have to wait a long time just for some video game footage that could be 10x smaller, and I'm sure most people will agree.

I tried those programs, but they produce jerky frame rates when record at 30 fps.

NTSC filter is a post-process unless I'm mistaken something. Directshow filter would be a nice thing to have. It would be compatible with Avisynth?

Youtube does automatically a low quality version from HD video for those, who prefer speed over quality. It doesn't look too bad either, but I have tested only with still images which don't eat much bitrate anyway. It might be a lot worse, when something is moving.

th e jerky frame rate does not appear in the video file though so use ZSNES's recording functions to make a replay and play that back while using FRAPS or something.

paulguy · Post by **paulguy** » Sat Jun 20, 2009 8:35 pm

If the capture is jerky then your computer simply isn't fast enough to do it. Which is unsurprising; even my core i7 drops frames with a large capture area.

I think you'll just have to settle for a lower resolution, perhaps, or using zsnes's unfiltered avi output.
