Convert mpg to avi (xvid) ?

bomix · 03-10-2005, 09:47 AM

This is apparantly an unusual question...

From what I can see, lots of people around here are converting video FROM avi INTO mpg.
I would like to convert video the other way around (ie. into avi, or to be more specific: XVID)

The "problem" is that I have a pvr-250 capture card installed which captures tv directly into mpg-files. These mpg's get kinda big quite fast, so I would like to capture the files and then convert them into xvid.

So my question is: How do I convert the mpg-files into xvid?

Thanks.

have a look into mencoder (part of mplayer)
and transcode.

their are already many tutorials around on how to use this software.

I tried mencoder without much luck...
I couldn't get it to produce anything else than black screen (with sound though). And besides, I wasn't exactly impressed with mencoder's speed...

I'll have a look at that transcoder thing you mention. Thanks.

The card PVR-250 only outputs MPEG-1 and MPEG-2 information. The problem taking this stream and saving it as a form of MPEG-4 will lose a lot of information in the process and dropped frames. I suggest first saving it to the hard drive first and then re-encode them into divx or xvid. This way it will not drop a lot of frames in the process. I suggest only using PVR cards for capture in either MPEG-1 or MPEG-2. If you want to encode using other codecs, buy a non-PVR capture card.

I know...
What I was trying to say was exactly that... First capture to a big mpg on the harddisk. Then reencode to xvid.
