Before you begin

Match the output to its destination.

Check the codecs inside the source container and the requirements of the target player, editor, or device before converting.

Prepare MKV for Apple TV with surround audio

Apple TV compatibility depends on the codecs, profile, audio layout, subtitles, and playback application rather than the MKV extension alone. Test the source first, then create a compatibility copy only when direct playback fails.

Create an MP4 with compatible H.264 video and supported multichannel audio, retain the source frame rate, and verify picture, channel mapping, subtitles, seeking, and sync before converting additional files.
