-hq doesnt work? (and a picture quality question): msg#00040video.ffmpeg.user
Hi guys, I'm trying to get quality as close to to that produced by the on2 vp6 codec, but havent been able to do that yet. Then I discovered -hq (high quality) in http://ffmpeg.sourceforge.net/ffmpeg-doc.html#SEC7 (which I'd somehow missed for some reason I can't tell) oh, and before sending this, I grabbed the latest cvs as of 2 hours ago, and rebuilt with the same issues :( So, my questions are thus: 1.) did the -hq get depreciated? and 2.) (and I know this is a realy big open ended question, so any general pointers would be apreciated, I don't expect a free full lesson in video compression tech) how do I get the best quality possible given a set bitrate and resolution? eg, if I want to stream at 768kb/s and have a screen size of, oh, 480x360 how do I get rid of (or minimize) all of the pixillation? Thanks. -- James here's my exact command lines and results: /usr/local/bin/ffmpeg -y -hq -i /Users/jbarros/RENDERALL -pass 1 - passlogfile /Users/jbarros/temp.txt -b 768 -bt 100 -s 480x360 -ar 44100 -ab 128 /Users/jbarros/FFMPEG_HIGH.flv FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard configuration: --enable-mp3lame --enable-gpl --enable-faac -- enable-x264 --extra-cflags=-DHAVE_LRINTF libavutil version: 49.0.0 libavcodec version: 51.9.0 libavformat version: 50.4.0 built on Apr 7 2006 15:44:09, gcc: 4.0.0 (Apple Computer, Inc. build 5026) /usr/local/bin/ffmpeg: unrecognized option '-hq' ------------------------------------------------------------------------ ---------------------------- /usr/local/bin/ffmpeg -y -hq -i /Users/jbarros/RENDERALL -pass 2 - passlogfile /Users/jbarros/temp.txt -b 768 -bt 100 -s 480x360 -ar 44100 -ab 128 /Users/jbarros/FFMPEG_HIGH.flv FFmpeg version CVS, Copyright (c) 2000-2004 Fabrice Bellard configuration: --enable-mp3lame --enable-gpl --enable-faac -- enable-x264 --extra-cflags=-DHAVE_LRINTF libavutil version: 49.0.0 libavcodec version: 51.9.0 libavformat version: 50.4.0 built on Apr 7 2006 15:44:09, gcc: 4.0.0 (Apple Computer, Inc. build 5026) /usr/local/bin/ffmpeg: unrecognized option '-hq' |
