I see many Steam pages and social media posts with dithered posterized mess of GIFs. Most GIf encoders are terrible. GIFs could be encoded much better: gif.ski is designed to encode high-color video-like clips efficiently.
Why do people keep using a format that’s 30 years old and was made for the simplest, transparent clipart animations?
Because it works everywhere, because it’s so old.
The next best option, a decade old WebP, is a mixed bag. In its best-compressing mode it will lower color resolution and add fringing like a JPEG. In its lossless mode it may be bigger than GIF.
If you have an option to use a proper video format, go for it. But often sites just allow upload of GIFs. If you send a newsletter you never know how primitive (Outlook) the client will be.
If I catch somebody sending videos as gifs in newsletter email, I’m gonna rethink my opinion on torture.
Also what kind of game videos do you share that you need compatibility with 1995 computers? The original Warcraft?
Even my idiotic ass could figure out how to put a video on YouTube, and I’m pretty sure you can put a link to that everywhere. Stop using gifs. Ffs.
