Activity Forums Compression Techniques encoding mpeg-2

  • encoding mpeg-2

    Posted by Peter Szasz on April 5, 2009 at 8:16 pm

    Hello,
    I’m capturing films on TV, and I simply want to cut commercials. Initially I had mpeg-1 files, they were successfully edited and exported along with a compression: a 4 GB film became 1.2 GB or so. I used Adobe media encoder with Custom preset and PAL setting. But whenever I try to do the same with mpeg-2 films, they will get just even bigger, and encoding takes extremely long time. I tried to manipulate bit rates, but to no avail. Can anybody advise, please, how to cut mpeg-2 videos, receiving the same file type with smaller size and within acceptable time frame?

    Thanks,
    Peter

    What MPEG-2 settings have you tried?

    How are you capturing the the File TV source?

    When I export MPEG-2 files, I use always the default settings, except for that I select PAL for TV Standard. I tried to set the Bitrate Encoding, but neither VBR, nor CBR was working (although with 1.7 CBR the file size was predicted as 1.5-2 GB – at the end of the process it became bigger than the original file).

    For capturing I have a Leadtek Winfast TV USB II Deluxe, similarly there are not too many default settings that I change therein. Actually I don’t even know which features I should take care of, because I’m absolutely beginner in the world of video files. But I thought it could be something very simple to capture a file, then cut a couple of minutes and save it in the same format as recorded.

    The Leadtek is capable of capturing either MPEG-1, MPEG-2 or MPEG-4. What have you got selected?

    I captured mpeg-2 files only. After editing with Adobe, I simply want to save in the same mpeg-2 format, but if possible, with smaller size (and not too low quality).
