  • 16:9 MPEG-4 in Compression Master

    I’m having a really hard time with this… please help!

    I have a source movie that is a 16:9 DV file that is letterboxed (the original film is in scope 2.35:1 aspect) – I need to convert this to an MPEG-4, keeping the same aspect ratio. I cannot seem to get the settings in Compression Master correct. No matter what I do, I seem to end up with a distorted image. I have tried setting the aspect ratio in the compression section to all options (1:1, 4:3 etc) and have tried many combinations of the resize filter, including turning it off altogether. The closest I came was a 16:9 file, but it was still distorted. In Apple’s Compressor, I can get it to work by telling it to use 100% of the source size, but cannot figure out the settings in CM. Compression Master is what I use for everything else, so ideally I’d be able to sort this out. Thanks very much.

    * in the encoder( mpeg4) check 16 9 asp ratio ( will not show in “preview”)

    * in the size choose a ratio 320 x 240 or 352 x 288 or some other related ratios ( not 16 9 ratios)

    * choose derive from source in the source pixel aspect ratio

    I hope that works,

    Thanks johan, but that didn’t work – still distorted…

    After much fussing around, I came up with these settings that seem to work:

    In encoder (MPEG4) I chose 16:9

    In resize, I chose custom, then set the aspect to 16:9 – I could then input anything I wanted for the width and it fills in the height for me.
    also in resize, I set pixel aspect to “assume 16:9”

    This works very well!

    Thanks for your input, and I hope this can help someone else down the line!

    Do you find that compression master works better than compressor for MPEG-2 with DVD as your final format?
