It belongs back in 1995 and has no place being used for anything anymore. Use a real fucking format. I mean it's no wonder it's 12 GB, If this had been a Webm it would've compressed into a couple MB easily.
Actually, any dedicated video format would do better than this. I have seen some sites that accept uploading of GIFs only to convert them and serve them as MPEG4. The additional advantage is supporting a larger colour range.
GIFs seemed cool until I discovered how big they were, compared to the equivalent video. Can anyone explain why they still seem attractive?
If it is because they are treated as images, maybe the browser image tag could silently accept MPEG4 or WebM and treat them as equivalent somehow?
