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.

Choose an output for the MPG source

MPG commonly contains MPEG-1 or MPEG-2 video, but the destination determines whether conversion is necessary. Test the source first and identify its video, audio, aspect ratio, frame rate, and interlacing.

Use MP4 for broad playback, MOV or an editing profile for a documented production workflow, and another container only when the destination requires it. Preserve picture geometry and verify one output before processing the rest.

Workflow direction

Follow the intended workflow below.
