Problem: mencoder - mkv to avi

Gordo_ posted 2007 Jun 30 03:12

This is what I want to do: I have a mkv file on 100 MB, and I want to encode it to XviD with about half the bitrate. (Source bitrate is 6700 kbit/s) This is what I type in commando prompt: : "C:\path\mplayer\mencoder.exe" "C:\path\source file.mkv" -oac mp3lame -ovc xvid -xvidencopts pass=1 bitrate=3500 -o "C:\path\mplayer\output\du.avi" When the encode completes I have an incomplete file. If I omit to include bitrate=3500 I get a brilliant encode, but the same file size and bitrate (which i wanted to cut in half) as the source. Am I doing anything wrong or is it just not possible?

(Source bitrate is 6700 kbit/s) Your source is 2 min long? Where did you get info from? What's in the mkv? Your command is wrong if you're not going to follow with a second pass. Bitrate setting will be ingored. By the way you need a seperator between options. So in the end you'd drop bitrate for pass 1, and for pass 2 you'd type pass=2:bitrate=3700 Just drop pass=1 flag for a one pass encode. If bitrate was not to work as preferred you could mess with fixed_quant. gl

Thank you, worked perfectly. And yes it is 2 min. long. Here's what I typed: : "C:\path\mplayer\mencoder.exe" "C:\path\source.mkv" -oac mp3lame -ovc xvid -xvidencopts pass=2:bitrate=3500 -o "C:\path\mplayer\output\output.avi"
