    Output file is much larger than trimmed input file

      I am relatively new user of Premier Pro CC (on a Mac Mini).

       

      My (simple) task is to trim a 749.6MB .m2ts. The details from MediaInfo are towards the bottom of the post.

       

      I set up a single sequence as AVCHD, 1920x1080, square pixels, 16:9, 25 fps, 48kHz audio.

       

      I brought in the m2ts file and trimmed off a couple of minutes from the start and end.

       

      I then exported the Media twice:

       

      1) "Match Sequence Settings", resulted in a 2.95GB .mpeg file.

      2) (after reading an article here) H.264 Blu-Ray, Multiplexer TS, resulted in 3.46GB file.

       

      Given then all I want is pretty much the same file coming out, but with some bits trimmed off the front and back (future ones will be several of these snippets edited together), in the same format in which it was recorded.

       

      It was recorded from an Hauppage PVR HD.

       

      Your guidance on what settings to use for the sequence and the export and any other relevant settings would be greatly appreciated.

       

      Thanks,
