    Unsupported Compression Type .MTS File

    Remblesaurousrex

      I have a Mac. I have been using Adobe Premiere pro, first a trial and then with a serial number. Importing the .MTS file was never a problem until today. I don't know what the difference is. I have not done anything different or changed anything. All of a sudden it doesn't recognize the video I already had in the project AND when I try to import it gives me the error "unsupported compression type." Why would it all of a sudden be unsupported when it worked perfectly before? I also uninstalled and re-installed it and I have the same problem. What should I do now? I process a LOT of video on a daily basis and I really need this to work! Please help me!

          When something like this happens on Windows platform, when it work well before, has often been due to PrPro reverting to trial mode.  When Adobe ships a trial mode version, they do not provide any MPEG codecs.  MTS is a form of MPEG.  Try opening a new sequence and see if any of the MPEG based formats are available.  If they are not available (greyed out) then you've been bit.  Do a search on "revert to trial mode."  There was some discussion that this was only on versions prior to CS5.5, but I am not sure.

            Well, I don't see any of the MPEG based formats, so that's obviously the problem. BUT, I used it as a trial before and it worked just fine with the .MTS. Never saw an error message. So, I just took on the full version--plugging in the serial number etc. It worked fine until today. The only thing I can think of is that I did a computer update. Have any insight into what might have changed?

             

            SFL46, I'll do that search and if it yields anything I'll update.

              There are no codec limitations of the trial version any more. See this page for information about that.
