Video preparation for MMS
Duration, codec, dimensions, MIME type, and file size are separate properties. The provider's supported format list should guide the export rather than an assumption about every smartphone.
Putting the guide into practice
Keep the key message concise, include captions in the creative where appropriate, and test the exported file on representative devices. Keep a useful text and link alternative.
- Codec
- Duration
- Captions
- Provider limits
- Alternative link
Limits and review decisions
Do not advertise a universal MMS video limit. The checker does not inspect every codec or verify carrier transcoding.
