Frequently asked questions
Will the MOV lose quality?
Both formats are lossy, so converting re-encodes the data once more. Using a high quality setting keeps the generational loss very small. Avoid converting the same file back and forth repeatedly.
Does converting MP4 to MOV re-encode the video?
Usually yes: the streams can be copied without re-encoding, in seconds and with no quality loss. A typical MP4 contains H.264 or HEVC (H.265) video with AAC audio. Otherwise the result is H.264 with AAC audio.
