    ac3 data rate problems

    Posted by Stephan Kay on November 20, 2009 at 7:06 am

    Hello all

    I am using FCP7 and Compressor to export a ac3 file and an mpeg which I later mux with the help of MPEG Streamclip. The file will play back in a MV720p-HD player.

    I am having problem with setting the datarate at 128kbps. The lowest preference setting in MPEG Streamclip seems to be 192 kbps.

    Is there a way around this?

    My Sequence is set to:
    Audio: 48k, 24bit

    My audio compressor settings are:
    File Format: Dolby Digital Professional
    Target System: Generic ac3
    Audio Encoding Mode: 2 (L,R)
    Sample Rate: 48k
    Data Rate: 128 kbps

    Any advice is much appreciated.

    Thank you!

    What is the reason not to use 192? Dolby sounds very ordinary at low data rates so I would advise using mpeg VBR audio if you want a small file that sounds Ok.
