  • Weird issues with MTS files in Premiere Pro CC2014

    Posted by Michael Pella on July 15, 2015 at 4:24 pm

    I have an editor who is working in Premiere Pro CC 2014 and has what appears to be a corrupt project file. She is editing with AVCHD footage that has been imported as a series of MTS files. For some odd reason, PP seems to be combining the video from one file and the audio from another when attempting to edit into a sequence. We’ve checked the original files at the Finder level and they appear to be fine. This only happens after importing into a project. I’m quite confused as to how this might be happening. Any thoughts?

    Clean out the media cache also clean out the folder manually.
    see if that will help.

    We had the same problem. I think it’s caused by two media-files having the same file-name and referring to the wrong cache-file name. Cleaning the media cache files resolved this (or deleting only the cache file with the same name as the media-file with the problem). It’s only happened with .mts-files, so I think it has something to do with the .mts foldestructure.

    If your camera starts anew at 0000.mts when you insert a new card, a project can wind up having several files named ‘0000.mts’, ‘0001.mts’, and so on. What could possibly go wrong?

    That I don’t know… It has something to do with the generation of the conform/media cache files. We had a lot of (very long) .mts files with similar names (mostly 0000.mts). As soon as I imported new files, some of the old ones in the timeline started to act strange (as in ‘playing audio from other 0000.mts-files). Deleting all the 0000-cache files (.cfa and .pek) and letting the cache files regenerate solved this issue, for a while… Tried to play around with the import settings (generate .xmp-files), but this didn’t solve it either. Worked around it by “render and replace” the audio track, which generated a new audio file.

    My best guess would be it is an error in the media cache database, linking the wrong cache file to the wrong media…
