Hi,
I’ve just started working with FFMpeg. I’m using it to convert video to FLV format as it’s uploaded to a web application. My first attempt was fine (I just gave it an input and an output), but I’m trying to improve the quality of the encoded videos. I’m trying to fix the quality by using two-pass encoding, but I’m doing something wrong as my output files are all empty. These are the lines I’m using:
ffmpeg –i myfile.avi –pass 1 –passlogfile pass.log output.flv
ffmpeg –i myfile.avi –pass 2 –passlogfile pass.log output.flv
I’ve tried specifying “-qscale 2” in the first command, “-b 300” in the second, and “-vcodec flv” in both – the result is always the same. Can anyone point me in the right direction?
Thanks!
