You can use some tricks like dithering to improve the quality and smooth the appearance but there is so much you can do to keep the file small. That’s why on the web nowadays much that you read GIF is in fact a MP4 file without sound.

Thanks Micael,

That all sounds right -- that's been my experience.  The downside of mp4 is that some browsers won't autoplay without user interaction.
But I wonder if what's suggested in your note above -- mp4 without sound will autoplay?



I’m not so sure, but I think that no sound MP4 can autoplay. I’ve seen situations like these before.
