Problem and solution

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 mixed video formats for iPad

AVI, MKV, MPG, and VOB are containers or disc-video files that can carry codecs or subtitle types the selected iPad playback app cannot decode. Test each source before deciding that conversion is required.

Use H.264 MP4 for broad compatibility, keep the source resolution and frame rate when practical, and verify picture, audio, subtitles, seeking, and sync in the intended iPad app before converting a large library.
