Question from total newbie!
I have a bunch of avi files that I downloaded and they have 2 sound tracks - russian and english. I need to remove the russian steam, someone recommended ffmpeg with these instructions "Use ffmpeg with "-acodec copy" and "-vcodec copy" options and specify which audio stream you would like to keep."
I muddled around and kinda figured out the syntax
ffmpeg -i in.avi out.avi -acodec copy -vcodec copy
I did not specify the audio stream to keep and the russian was gone

I read-up more and used switch -qscale 0
ffmpeg -i in.avi -qscale 0 out.avi -acodec copy -vcodec copy
but output file now 2.6GB ( russian is still gone )
This is the input video information that I get when I run "ffmpeg -i in.avi"
Input #0, avi, from 'in.avi':

Stream #0:2: Audio: ac3 ([0] [0][0] / 0x2000), 48000 Hz, 5.1(side), fltp, 384 kb/s
Can someone help me with command line parameters that I need to use to keep the same quality video/size? and if you can tell me how to specify which audio steam to keep that would be awesome!
Thank you
