 ffcvt - ffmpeg convert wrapper to make it simple to do high efficiency
 audio/video compression (Opus/H.265) encoding, and for youtube as well.

 The next-generation High Efficiency Video codec, HEVC and VP9 can produce
 videos visually comparable to libx264's, but in about half the size;

 128K to 256K bandwidth.

 codec/encoding capability while shielding people from the
 complicated ffmpeg command line option settings, while versatile
 and powerful enough to allow advanced users to touch every corner
 of audio/video encoding.
