Why Convert M2V to M4V?

M2V is an MPEG-2 video elementary stream — it contains only video data with no audio track. It's used in professional DVD authoring workflows where video and audio (typically AC3 or WAV) are mastered separately before being combined into a final DVD.

Converting M2V to M4V re-encodes the video-only stream into Apple's M4V container with H.264 compression and AAC audio support. This makes the file playable on Apple devices, iTunes, and standard media players — though since M2V has no audio, the output M4V will also be silent unless you add audio separately.

Frequently Asked Questions

Why is there no audio in my converted file?

M2V files contain only video — no audio track. The output M4V will be silent. In DVD authoring, audio is stored in a separate .ac3 or .wav file.

What CRF value should I use?

CRF 18 is visually lossless. CRF 23 (default) balances quality and size. For archival, use CRF 18 or "Highest" preset.

Can I batch convert?

Yes. Upload multiple M2V files and download M4V results individually or as a ZIP archive.
