Why convert MKV to GIF?

MKV isn't supported by many phones, TVs, editors and websites. GIF plays as a looping animation everywhere, with no video player needed.

The size math: MKV vs GIF

A minute of MKV video weighs about 15 MB; its soundtrack alone as GIF is 40 MB. Extracting audio shrinks the file about 2.7× larger.
