Hi!
I'm new to record AVIs and further encode them to mpeg. I had a tool to cut mpegs, but so far I have not found a tool to cut AVIs (mpeg4) on linux.
Take a look at avidemux: http://fixounet.free.fr/avidemux/
Now that you mention it, and searching the old messages I can't understand how I could miss this before. Well, until a few days ago I only handled mpeg-files. Thanks. Anyway, avidemux is a great and comfortable tool, exactly what I needed. Only, the 10 second tolerance for cutting persists. I have found two possible solutions: either I encode in mjpeg which results in files twice as big with lower quality, or I raise the number of keyframes. After looking through the encoding-tips.txt I tried the option: keyint=50 This works, now I have only a two second tolerance, which is probably enough. But there is also "Key frames are significantly larger than P or B frames, so the less key frames you have, better the overall movie will be." Huh? Shouldn't it be the other way, the more P-frames I have, the better the output? After all, more memory is used which should result in better quality. Besides that, I would still like to know why the time within a VCD differs so much from the one mentioned in -ss. It's not essential, but I am interested. -- Lehmeier Michael <m_lehmeier@gmx.de>
