any reason for using ogg, the guys on the mailing list are rather not happy with ogm and ogg for video. I would suggest moving to x264 and aac in a mkv container. this is what i use on my video files from my digital camera (power shot g10 - cannon). my requirement was ease of view from over the internet. also I use 2 pass encoding and mp4 and scales to quarter pal ~ 300bits (this is a cut and paste from the output of my scripts lanrisk.addr is the input file) Video Pass 1/2 nice mencoder -really-quiet -vf scale=::::::qpal,hqdn3d=2:1:2,pp=de,uspp=5,harddup -af volnorm=1\ -ovc x264 -x264encopts \ pass=1:turbo=2:nob_pyramid:bframes=1:subq=6:frameref=3:partitions=all:me=umh:weight_b:threads=auto:qcomp=0.75:mixed_refs:nofast_pskip:trellis=2:nodct_decimate:nopsnr:brdo:bitrate=300 -oac faac -faacopts br=128:object=2:tns:mpeg=4 -passlogfile \ "/tmp/user/1000/myConvert.14Xa4/divx2pass.log" -o /dev/null \ "lanrisk.addr" -idx >>"/tmp/user/1000/myConvert.14Xa4/stdout.txt" \ 2>>"/tmp/user/1000/myConvert.14Xa4/stderr.txt" nice mencoder -really-quiet -vf scale=::::::qpal,hqdn3d=2:1:2,pp=de,uspp=5,harddup -af volnorm=1 -ovc x264 -x264encopts pass=2:nob_pyramid:bframes=1:subq=6:frameref=3:partitions=all:me=umh:weight_b:threads=auto:qcomp=0.75:mixed_refs:nofast_pskip:trellis=2:nodct_decimate:nopsnr:brdo:bitrate=300 -oac faac -faacopts br=128:object=2:tns:mpeg=4 -passlogfile "/tmp/user/1000/myConvert.14Xa4/divx2pass.log" -o "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr.avi" "lanrisk.addr" -idx >>"/tmp/user/1000/myConvert.14Xa4/stdout.txt" >>2>>"/tmp/user/1000/myConvert.14Xa4/stderr.txt" nice MP4Box -aviraw video "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr.avi" -out "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr.h264" >>"/tmp/user/1000/myConvert.14Xa4/stdout.txt" >>2>>"/tmp/user/1000/myConvert.14Xa4/stderr.txt" nice MP4Box -aviraw audio "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr.avi" -out "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr.aac" >>"/tmp/user/1000/myConvert.14Xa4/stdout.txt" >>2>>"/tmp/user/1000/myConvert.14Xa4/stderr.txt" nice mv "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr_audio.raw" "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr_audio.aac" >>"/tmp/user/1000/myConvert.14Xa4/stdout.txt" >>2>>"/tmp/user/1000/myConvert.14Xa4/stderr.txt" nice MP4Box -add "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr_video.h264" -add "/tmp/user/1000/myConvert.14Xa4/lanrisk.addr_audio.aac" -new "lanrisk.addr.mp4" >>"/tmp/user/1000/myConvert.14Xa4/stdout.txt" 2>>"/tmp/user/1000/myConvert.14Xa4/stderr.txt" nice touch -r "lanrisk.addr" "lanrisk.addr.mp4" >>"/tmp/user/1000/myConvert.14Xa4/stdout.txt" >>2>>"/tmp/user/1000/myConvert.14Xa4/stderr.txt" > > > Cheers, > > Seb > -- > SLUG - Sydney Linux User's Group Mailing List - http://slug.org.au/ > Subscription info and FAQs: http://slug.org.au/faq/mailinglists.html -- "Over 75 percent of white Americans own their home, and less than 50 percent of Hispanos and African Americans don't own their home.
