I've just started using ffmpeg.
Common here are VHS tapes with two stereo sets of audio that and we capture to 10-bit YUV and ffmpeg recognizes as four mono channels in one stream. I'd like to store these masters as two streams of two-channel audio and generate mpeg4, prores, and msmpeg4v2 derivatives; with aac, aac, and mp3 audio for each of those respectively. Can I do that with two streams of audio for all cases above? Any reason I shouldn't bother doing so? Assuming I should reformat the audio, any advice how? I've successfully experimented with extracting the four channels of audio, reconstructing two streams of two-channel audio from that, and then replacing the video's original audio with the new audio streams. But I wonder if there is a one command line solution? Thanks in advance for any advice power users might provide.
