    “-threads 0” doesn’t seem to default to all available. Errors out. I then entered 4 and its chugging along. Doesn’t utilize the last three cores nearly as much as the first but at least they are doing something.

    I will try an output to another codec and container at another time to experiment with the audio.

    A only slightly related question.

    How do I get my Ubuntu 12.04 64-bit system to process the trans-code on all/more of my processor cores? FFmbc is only using one core on 100% of the trans-code.

    Okay. Figured it all out for what I was trying to do. FFmbc, as it seems, was getting over run trying to output the audio even though I wanted it to copy the codec. I ended up using the line as noted below and all is encoding and playing back well. I’ll double check the A/V sync further into the trans-code after the first one finishes.
    ffmbc -i infile.mov -vcodec mpeg2video -b 12000k -acodec ac3 -ab 384k outfile.mpg
    I sure hope this helps someone else.
    Again, I am trans-coding Apple ProRes 422 Normal Quality recorded at 145Mb/s on a Sound Devices PIX 240i.

    I compiled a 64-bit .deb package for Ubuntu 12.04.1 LTS from my system.
    Download at nerdsonstandby.com/dwnlds/ffmbc-0.7_0.7-rc7-1_amd64.deb Please prefix the install as Milivoj Ivkovic noted above with the yasm dependency.
    sudo apt-get install build-essential yasm
    Let me know if it doesn’t work. It installed on my system.

    Tried the code you suggested. Here is some of the output:

    The last time I tried, the video was perfect, however, the audio is non existent.
    I used:

    I too am interested in converting prores. My system is running Ubuntu 12.04.1 64-bit. I can get a clean picture turning 422 normal quality to mpeg or whatever with FFmpeg, however, I am loosing audio altogether. I would like to use FFmbc if it will be professional.
