MTS File Metadata Support

[otown]

Any idea when we'll be able to modify metadata in MTS files?

thx...

I'm sorry to say that I doubt ExifTool will ever have the ability to write these files.  See this commentary for a few reasons why this format is at the bottom of my list.

Hi Phil,

Cameras like my Sony RX100 and RX100 IV produce only MTS files for higher quality video output so I've now got a huge number that are a nightmare to manage due to the metadata.

I was wondering what would you recommend as a workflow for managing MTS files metadata given all the limitations of the format? The MTS files play fine on all the devices I use, but metadata is inconsistent and some have time offsets/errors that I can't correct with ExifTool. Any tips for wrapping the original MTS in a lossless way to allow sensible metadata to be copied into the new file and then manipulated as needed by ExifTool?

Many thanks,

Stephen

There is probably a way to losslessly convert M2TS to MP4, but I don't know how.  I would recommend doing that.  M2TS does not support any metadata.

I did some searching around and it looks like it might be possible to losslessly convert it to mp4 with ffmpeg.  Try a command like this
ffmpeg -i movie.M2TS -vcodec copy -acodec copy out.mp4

There were a lot of links for an Apple script that would do this, but unfortunately they're all dead.

Thank you - let me investigate and will report back.
