Hi there, since dyas i am trying to figure out, what the right cmdline options are, i searched the web, tried various settings, but with no success... I used mencoder to render avis - but since i use vlc and thus ffmpeg, there has to be a solution. my previous mencoder setting - still working but with 1 audio track: audio: 'mencoder "'.$PARSEFILE.'" -ovc frameno -o frameno.avi -oac mp3lame -lameopts br=128:cbr:mode=3 -af resample=48000:0:2 -srate 48000'; 1 pass: 'mencoder "'.$PARSEFILE.'" -oac copy -vf pp=lb -ovc lavc -lavcopts vcodec=mpeg4:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:autoaspect:vbitrate=1000:vpass=1:threads=2 -o "'.$out 2 pass mencoder "'.$PARSEFILE.'" -oac copy -vf pp=lb -ovc lavc -lavcopts vcodec=mpeg4:v4mv:mbd=2:trell:cmp=3:subcmp=3:mbcmp=3:autoaspect:vbitrate=1000:vpass=2:threads=2 -o "'.$out works plus qaulity is for tv okay.... can anybody help me translate that into ffmpeg lingo? i am using linux and only linux.... my first start was : 1 pass: "ffmpeg -v 2 -y -i $PARSEFILE -b 1200k -bt 4000k -vcodec mpeg4 -pass 1 -an $WRITEFILE.avi"; 2 pass "ffmpeg -v 2 -y -i $PARSEFILE -b 1200k -bt 4000k -vcodec mpeg4 -pass 2 -acodec libmp3lame -ac 2 -ar 48000 -ab 128k $WRITEFILE.avi"; but that didnt work - filsizewise I dont want to do h264 encoding. That works but a) is slow as grandma (which is nothing bad) b) filesize is not satisfying c) decoding cost cpu and doesnt work with vlc (dont ask here - ista fact).. so does anybody have a suitable 2 pass ffmpeg string? Thanks in advance NJ

Here's roughly what I use to encode in xvid format: ffmpeg -i $from -deinterlace -y -vcodec libxvid -b 1000k -acodec libmp3lame -ab 128k -sn -pass 2 $out.avi HTH Dominique -- http://config-model.wiki.sourceforge.net/ -o- http://search.cpan.org/~ddumont/ http://www.ohloh.net/accounts/ddumont

i managed some usefull results with that parametrization, i stripped the deinterlace plus -sn parameters, they took took quite a while rendering: #>working on : 20100330_2015_-_SWR_FERNSEHEN_RP_-_TATORT__LEERSTAND.ts #>writing to : /mnt/moonshine/c2/20100330_2015_-_SWR_FERNSEHEN_RP_-_TATORT__LEE$ #>doing a AVI 2Pass encoding from WinEncodeTest ffmpeg -v 2 -threads 2 -y -i "/nfs/dm7025/movie//20100330_2015_-_SWR_FERNSEHEN_RP_-_TATORT__LEERSTAND.ts" -vcodec libxvid -vtag XVID -maxrate 1800kb -b 1200k -qmin 3 -qmax 5 -bufsize 4096 -mbd 2 -bf 2 -flags +4mv -trellis -aic -cmp 2 -subcmp 2 -g 300 -acodec libmp3lame -ar 48000 -ab 192kb -ac 2 -pass 1 -map 0.0 -map 0.1 -map 0.2 "/mnt/moonshine/c2/20100330_2015_-_SWR_FERNSEHEN_RP_-_TATORT__LEERSTAND.avi" -newaudio ffmpeg -v 2 -threads 2 -y -i "/nfs/dm7025/movie//20100330_2015_-_SWR_FERNSEHEN_RP_-_TATORT__LEERSTAND.ts" -vcodec libxvid -vtag XVID -maxrate 1800kb -b 1200k -qmin 3 -qmax 5 -bufsize 4096 -mbd 2 -bf 2 -flags +4mv -trellis -aic -cmp 2 -subcmp 2 -g 300 -acodec libmp3lame -ar 48000 -ab 192kb -ac 2 -pass 2 -map 0.0 -map 0.1 -map 0.2 "/mnt/moonshine/c2/20100330_2015_-_SWR_FERNSEHEN_RP_-_TATORT__LEERSTAND.avi" -newaudio Example: Output #0, avi, to '/mnt/moonshine/c2/20100330_2015_-_SWR_FERNSEHEN_RP_-_TATORT__LEERSTAND.avi': Stream #0.0: Video: libxvid (hq), yuv420p, 720x576 [PAR 64:45 DAR 16:9], q=3-5, pass 2, 1200 kb/s, 25 tbn, 25 tbc Stream #0.1(ger): Audio: libmp3lame, 48000 Hz, 2 channels, s16, 192 kb/s Stream #0.2(2ch): Audio: mp2, 48000 Hz, 2 channels, s16, 192 kb/s Stream mapping: Stream #0.0 -> #0.0 Stream #0.1 -> #0.1 Stream #0.2 -> #0.2 it gives a reasonabel gig- file for 90 minutes if ts- source. But if i take a look at the avi, i see that ther is only 1 mp3 plus another mp2 stream. Why they arent both mp3 as a specified? Thought mp3 will be much smaller than mp2. Another question: Does it make sense to use 192kb for tv speech (simple stereo + amp which has a surround chip - converts stereo -> surround....) or id thst oversized too? Cheers Nj
