mencoder not accurate

sumeet inani · 06-30-2010, 05:13 AM

i am using ubuntu 8.04
I wanted to clip from a movie so I ran

Code:

mencoder -ss 2453 -endpos 34 InpuTFile -acodec copy -vcodec copy -o Output

I changed the ss value still it cut from same frame of the video.
It seems mencoder works faster than ffmpeg but jumps to keyframe hence cannot jump to accurately specified second.

Well if you copy you have to start on a key frame, otherwise it'll just look like a bad trip until you get to the next one. Nothing you can do about that without reencoding the video as I understand the situation.

Do you mean if i use different codec for output audio & video then I can start from any moment?

I will try that.
