  1. Hi, I have been using m2-edit pro to edit my mpeg 1 files. The thing is the gop sequence that I have been editing starts with a closed gop of IBBPBBPBBP and the rest are open. When I edit the closed gop out of the whole sequence, I still get a closed gop in my new mpeg-1. Anybody know why this happens?

    Next question. In m2-edit pro the gop sequence dosen't start with an I- frame it is shown as BBIBBPBBPBBP and m2-edit pro says that this gop is open. I realize that this is the bitstream order and the display order is actually IBBPBBPBBPBBPBB so where in bitstream order do I make my cuts?

    Is it possible to edit out the closed gop, without creating a new closed gop or messing up the other gop's? So far I have had no luck. Since I have went to editing at the gop level and not by frame my video's have come out looking absolutly great. I use mpeg_stat.exe to look at my full mpeg file witch is the combination of 6 smaller mpegs all of the same resolution, frame reate, and bps (show's commercials have been edited out) and you can see the seams where they have been joined. I do notice at those seams when watching the video a little bit of loss in the apperance of the video.

    Is my problem the amount of frames being edited meaning not divisble by a set number of frames? What number is a correct non broken gop for 29.97 fbs supposed to be divisble by? Is it 12, 15, or 16?

    any help would be appreciated. thank you for your time.

  2. What I do is use the "Edit on I frame boundary" option by holding down the SHIFT key when advancing or rewinding through the file. Advance forward to close to where you want to edit, hold the SHIFT key, and click backwards or forwards to get to your edit point. That should help you get complete GOPS when you edit, and the clip will stop in the right place without running on.
    Hope that helps.

    You can also add in a transition between cutpoints to blend in the "seams". Just a simple fade in or out should work.
