Hey, nice recipe! Works great - except for: http://bugs.cinelerra.org/show_bug.cgi?id=438 (dropouts occurring in rendered WAV if the edit is nudged or shifted) I have to move the audio out, because the video lags in my source material. But I've got a workaround: 1. split off audio from my source material with avidemux, save as .WAV 2. load the .WAV into audacity, and add a second of silence at the start 3. export from audacity to another .WAV 4. load this second .WAV into Cin 5. edit out enough of the starting silence to get good a-v sync 6. then, follow Valentina's recipe Ahh, finally! A good quality result.
