On-device encoding can work the processor harder than ordinary playback during this MTS-to-MP4 job.
High-resolution MTS footage increases conversion time and memory use.
Keep the source until the MP4 result passes a full playback check.

MP4 serves phones, browsers, players, and upload forms, whereas MTS commonly serves AVCHD cameras, editors, and archives.
For MTS-to-MP4 delivery, plan for destination-specific internal codec rules.
After leaving MTS, the receiving app must support the streams encoded inside MP4, not only its extension.

MTS to MP4 taking too long? Process a shorter section to determine whether file size is the bottleneck.
MP4 converted from MTS not opening? Test a compatible player and inspect the output streams.
If MP4 is rejected, compare its codec and stream settings with the destination specification.

When does MTS to MP4 conversion make sense?

It is useful when MTS media created for camera-media workflows must enter a MP4 system designed for general playback and sharing.

Where is the MTS source processed?

The browser prepares MP4 from MTS on this device instead of sending the source to a remote conversion server.

How can I approve MP4 converted from MTS?

Test the MP4 file in the receiving app and compare duration, picture, sound and timing with the MTS source.
