I tried adding -vcodec libx264 -vpre=hp but besides MUCH longer worktime, nothing much is gained. (for youtube, I just change bitrate to 2048k)Įxample: in this case, when input file size is ~370 MB, bitrate 4096k gives me 177 MB output, and bitrate 2048k gives 90 MB. ***ffmpeg -i INPUTFILE.MPG -b 4096k -f mp4 -ar 44100 -ac 2 -acodec aac OUTPUT.mpg

Now… I found that bitrate 4096k is good for safekeeping and 2048k for youtube. I have a camera with which I make my videos, and I need 2 converts, one for safekeeping and making DVD sometimes, and other to post to Youtube. What I do not know is when to use which, etc, but this is out of the scope.

I am not tottally illiterate for video files, I do know that mp4, flv, avi and other formats are containers and that h264, mpeg2 etc are encodings.
