Hello folks, Reading same samples of command line on google I'vemet the -hq and -bitexact options in ffmpeg. I tryed to execute ./ffmpeg -h but these options arent in the switches list. Could you explain me what they are used for? I'm trying to get maximum quality in 3gp files I'm encoding from the avi format with ffmpeg, and when I was reading two pass command line samples I saw these two options. My ffmpeg version follows: FFmpeg version SVN-r5790, Copyright (c) 2000-2004 Fabrice Bellard configuration: --enable-gpl --enable-amr_nb --enable-amr_nb-fixed --enable-am r_wb --enable-amr_if2 --enable-faac --enable-faad --prefix=/usr/bin/ffmpeg/comp3 --libdir=/usr/lib/ffmpeg/comp3 --incdir=/usr/include/ffmpeg/comp3 libavutil version: 49.0.0 libavcodec version: 51.10.0 libavformat version: 50.5.0 Thanks Marlon
