GIF vs. Lossless WEBP

[jay123210599]

Which type of animated image would have the higher quality, a 1920x1080 high quality GIF, or a 1024x576 lossless animated WEBP? If I extracted frames from them as PNG files, which ones from have higher quality?

It would be superfluous to call a GIF high quality because there is nothing to adjust; it is lossless and 256 colours.

Though subjective, there being a resolution difference, the WebP image would likely be better quality because it stores more colours. If the original's palette falls within 256 colours, the GIF would win.

Placed in full context, though, other formats beat WebP in both lossy and lossless modes; for example, JPEG XL.

First of all, Shutter Encoder can make high quality GIFs. Second of all, the source is a YUV420 video. And lastly, what other formats beat WEBP? AVIF and HEIC/HEIF do not count because there is limited support for them.

What I mean is, a GIF is a GIF, and there is no setting to adjust quality.

Are you saying that Shutter Encoder can make GIFs with more than 256 colours? And you are right, compatibility is a problem, so at the end of the day, you should use WebP for that YUV420 source. Or, if the GIF looks all right when dithered down to 256 colours, use that.

Just give up. Who the f*ck will allow you to upload such "images" to their website?

Talking about support, animated AVIF is roughly as well supported as animated WebP these days.

I think what he mean by high quality GIFs is just about the palette and dither method.
Even if you somehow magically make GIF use more than 256 colors the support outside your magical software is non-existence. (remember how we care about support?)

But when the color "depth" and resolution differences are introduced together, the problem simply becomes the matter of the preference of the one who make the encode.

TRY IT YOURSELF.
THEN ASK YOURSELF.
WHICH DO YOU PREFER.

The entity "Jay" (SCP-Doom9-123210599) keeps asking questions follwoing one or more of these rules:
1) The question can easily be looked up with a simple web search engine search.
2) The question can easily be answered by performing the actions involved in the question. "F*ck around and find out".
3) The question is ambiguous.
4) The question is subjective.
5) The question is a variation of previously asked question(s).
