Wow, for some reason setting it at 3000000 (>3M) did some good difference and at 4000000 (<4M) it looked even better now. I guess it would be best to compute the bitrate on my own than rely on the input files. My next question would be do you know of any material on calculating bitrate (MPEG4 would be fine since it would be the most used) so that I can calculate it while in the program? _______________________________________________ libav-user mailing list [email protected] https://lists.mplayerhq.hu/mailman/listinfo/libav-user
