I would like to install FFmbc on ubuntu 10.10. I found a walkthrough for debian but it does not work. Does someone have a walkthrough for installing it on Ubunut?
You certainly have solved your problem by now, but in case others come across this thread, I just did the following on Ubuntu 12.04 LTS:
Make sure you have the necessary tools installed:
After downloading the latest source of ffmbc, and unpacking it into ~/src/
make gave out lots of warnings, but it seems to work fine anyway.
I compiled a 64-bit .deb package for Ubuntu 12.04.1 LTS from my system.
Let me know if it doesn't work. It installed on my system.
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.

ffmbc is quite "professional". It is it's target audience after all. However, it is not "casual-user-friendly". It's main advantage - being a command-line program, thus scriptable - is a disadvantage for other uses.
You can probably find help on the correct options to use for your purpose in the wiki (http://code.google.com/p/ffmbc/w/list), in the ffmbc-discuss google group, or with a specific web search. Note that ffmpeg now also supports ProRes, and is more widely used than ffmbc. So search for both.
Maybe we can help here as well, if you let us know what result you want, and show us the output of
FFmbc output from that file is:
The last time I tried, the video was perfect, however, the audio is non existent.
Looks like you suppressed the audio with "-an".
You could try something like this:
(I cannot test it right now, but hopefully that will be closer to what you are trying to do)
Tried the code you suggested. Here is some of the output:
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.
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.
Maybe the mpeg video standard doesn't accept 24 bit audio, which is what you had in your original. That would explain why it now works, since you also transcode the audio.
BTW, you had a "-t 360" option in your original line, for testing I guess. If you want to restrict the duration, put that option before the input file. To transcode only the first 60 seconds:
ffmbc -t 60 -i $INPUT ...etc.
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.
How do [...] process the trans-code on all/more of my processor cores?
-threads X (where is X is the number of threads to use)
To use all available cores:
"-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.
