Hello Grr?goire, yes, I recorded Panic Room on Pro7 and tried to reencode it, because 14GB are far too large for DVD ;-) I used projectX to demux and correct the .vdr-Files, then video and audio are multiplexed again to a mpg-file. Afterwards I used ffmpeg to encode the film (in two passes): ffmpeg -i Inputfile.mpg -vcodec mpeg4 -pass 1 -passlogfile logfile -ac 2 -acodec mp3 -ab 128 -sameq -hq outfile.avi All that was done with a small shellscript, which i originally made for converting short movies to divx. The resulting file is 6,5 GB in size, picture quality is perfect ("-sameq") but I experienced problems with audio (no sound after 1:05:00), with other tests I got unsynced audio with xine, synced audio with gmplayer ... That has to be tested further .. But back to your original question - with the above mentioned parameters for ffmpeg it should be fine. ffmpeg also could copy the audio: -acodec copy, that would reduce some of the problems I have ;-) I hope this is helpful for you, Regards, Ulf -------------- next part -------------- A non-text attachment was scrubbed...
