i am trying to create a 2 pass xvid avi from an mkv. i can do it with a single pass no problem. but when i try a 2 pass i get this message before the first pass starts. [bold]Cannot open output file '/dev/null'.[/bold] here is the exact command line i am using. "c:\program files\mplayer\mencoder.exe" "c:\temp\movie.mkv" -oac mp3lame -lameopts cbr:br=128 -ovc xvid xvidencopts pass=1 -o /dev/null can anyone help me out? thanks in advance. i'm a noob to mencoder. would use vdub except the mkv is vfr and a/v won't sync.
