Before you begin

Check the AVCHD source before choosing a workflow.

Keep the original camera folder when available, then confirm the recording mode, frame rate, and destination support before converting.

Prepare Sony AVCHD for Adobe Premiere Pro

Current Premiere Pro releases can import many AVCHD structures directly, but isolated MTS files, high-frame-rate modes, or incomplete camera folders may still cause missing audio or uneven playback. Keep the original card structure whenever it is available.

When conversion is necessary, match the source resolution and intended sequence frame rate. Test one output clip in Premiere Pro for cadence, picture, audio, and sync before processing the complete recording set.

Match Adobe Premiere Pro

Choose Editing > Premiere/VEGAS > MPEG-2
