I hacked together a little Ruby script to do something similar a few months back, might be useful to somebody:

https://github.com/space150/gifvine/blob/master/gifvine.rb

It runs server-side however, and requires several dependencies (ffmpeg, imagemagick) unlike JVine which runs client-side as a Java applet.

Seems like it be highly useful for sites that do backend conversion. Never been a big fan of ruby but its cool seeing its uses.

I've gone ahead and slapped together APNG support, which not only cuts file sizes down; but conversion takes about 5 seconds for the largest MP4 I tested.

Sadly I realized not every browser supports APNG.

It's very upsetting that many people did not take APNG seriously. GIF is too outdated on this point.
