Quick use cases
- Adapt camera-media workflows to a workflow built for multi-platform libraries
- Supply MKV when an editor, player, or delivery form will not accept MTS
- Create a MKV copy from MTS for flexible media libraries and archives
Workflow
- Choose a MTS file from your device
- Confirm the planned MKV filename
- Create the MKV version
- Download MKV and test it in the destination app
Processing notes
- Local conversion competes with other open apps for processor time during this MTS-to-MKV job.
- Long MTS files consume more memory and take longer to decode.
- Check picture, sound, and timing in MKV before removing the source.
Compatibility notes
- MKV serves flexible media libraries and archives, whereas MTS commonly serves AVCHD cameras, editors, and archives.
- For MTS-to-MKV delivery, plan for rejection by some TVs and upload forms.
- After leaving MTS, the receiving app must support the streams encoded inside MKV, not only its extension.
Troubleshooting
- MTS to MKV taking too long? Free local memory and keep the conversion tab in the foreground.
- MKV converted from MTS not opening? Test a compatible player and inspect the output streams.
- Inspect the generated streams when an app recognizes MKV but refuses playback.
MTS to MKV converter FAQ
When does MTS to MKV conversion make sense?
It is useful when MTS media created for camera-media workflows must enter a MKV system designed for multi-platform libraries.
Where is the MTS source processed?
The browser prepares MKV from MTS on this device instead of sending the source to a remote conversion server.
How can I approve MKV converted from MTS?
Test the MKV file in the receiving app and compare duration, picture, sound and timing with the MTS source.
