Hello, So far I used this command to convert video files: ffmpeg2theora.linux --optimize --no-upscaling --videoquality 5 --audioquality 1 --contact=http://navratil.cz a.mp4 Now I'm trying use --two-pass parameter with ffmpeg2theora 0.25+svn16645 - Xiph.Org libtheora 1.1 20090822 (Thusnelda) if I just add --two-pass, then I'm getting Could not set up the first pass of two-pass mode. Did you remember to sp...

Hello, Can I achieve with --two-pass better quality for same size or --videoquality 5 is fine and I will not get any improvement? Thank you, Jiri

I tried to encode some video from a DVD with encoder_example and ffmpeg2theora, and it looked great, except that with both encoders the A/V sync would drift noticeably after about 10 minutes, and by the end of a two hour movie it would be a couple seconds off. So instead of just whining about this and waiting for someone else to fix it, I decided to try to learn about what's causing the
