Finally plays on my TV
Had a bunch of MKV movies that my Smart TV refused to play. DocDoc Translate converted them all to MP4 and now everything works perfectly. Took like 5 minutes total.

Zero quality loss, seriously
Was worried about losing quality converting a 4K MKV. DocDoc Translate remuxed it perfectly — same sharpness, same audio. Couldn't tell the difference.
