If I use -vf format=rgb8 when making images with ffmpeg, will the result be lossy even with lossless formats like PNG? If so, how do I fix that? What supported pixel formats are lossless with RGB display, other than the titular format itself?

You probably mean "rgb24" . 8 red, 8 green, 8 blue . Or 8bits per channel component
You can check what pixel formats are supported by various encoders in ffmpeg using ffmpeg -h encoder=blah
8bit RGB displays would use RGB24, or GBRP (RGB planar, 8 bit depth) . There are other variations such as bgr24, bgr0, 0bgr, rgb0, 0rgb, a few others. They all mean 8bit per channel RGB , but are arranged slightly differently -
Meaning they'll have the same file size? What if I use pal8, gray, ya8, gray16be, ya16be, or monob?Originally Posted by poisondeathray

ffmpeg is quite descriptive on supported pixel formats:

Does YUV video have always the same size? Why RGB would be different?
Google how compression works. These basics are holding you down, looking for a nonsense solutions.
To sum it up (latest month) , now you know to have good looking image, it needs to be about 0.5MB. That depends on picture, whats in it, I just take your example.
So imagine 10 second video image sequence. You'd need 120MB (24fpsx0.5MBx10seconds). When you realize how much of a size would be 10s cut out of your video, you'd realize what you are doing. That 10 second sequence would hardly be more that 40MB. And that's an exaggeration, perhaps anime could be much less than that. -

Meaning quality will look terrible for RGB8 because you have too few bits per channel. It will be posterized and blocky
pal8 is for GIF - quality will be terrible for a PNG
The others have no color, they are greyscale , and the ones with "a" such as ya8 ya16be have an alpha channelLast edited by poisondeathray; 9th Feb 2024 at 17:30.
