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.
