DivX / XVid

MunsterCycling

Running a FC5 box and want to set it up to do my DivX/XVid encoding, looking for software that will allow me to do this. Anybody point me in the right direction as to what I should use and where to get and config it?

TIA

MEncoder should do the trick. I think it's part of the mplayer package. It must have got on my computer somehow.

Mplayer site

steveland?

Check out my shell script in the shell scrip thread that outputs a command to mplayer depending on what size you want the file, what chapter it starts on, how long the piece of video to be encoded is.

I find it very handy.

Will do, thanks. Any more suggestions people?

mencoder is really excellent, and there is plenty of information out there on it. There is also avidemux (which is a nice virtualdub style GUI, only better) and ffmpeg (which is command line).

There is also the command line x264 application, but it needs to be frameserved by mplayer (or some such...if you're very intersted in this, ask me ). mencoder can also output x264 encoded files.

What kind of frame rates do these programs get?

On the windoze box I used to do this on I'd get 35+ FPS depending on content to lowest 20-24 FPS. Only ever used the single pass encoder though and have had very little issues with this (the machine is currently down hence the move to a *nix encoder...

You can specify the framerate you want.

mencoder <your DVD chapter> -ovc lavc -lavcopts vcodec=mpeg4:vhq:vbitrate=<The FrameRate You Want> -vop scale -zoom -xy 640 -oac mp3lame -lameopts abr:br=128 -o /home/$USER/Videos/$OUTPUTFILE.avi

Sorry I meant frame rate as in when its trans coding into DivX from either DVD disc or directly from .vob

Say movie is 2hours, how long will it take on average to transcode to DivX?

It's mostly dependent on your processor. When encoding xvid for my psp, I get around 80 fps. I have a 4600+ X2. I'd expect to get around 50FPS for a dvd quality encode (from a dvd). You could increase this by using one of the newer mencoders (which support threading).

BTW, the 2 pass encode really is worth the extra time....The first pass can be sped up considerably with some command line options. Just do it overnight.

MunsterCycling

Dam was waiting for someone to say that

Will try the 2 pass encode when I get this setup and see if it makes a difference even though I suspect I know the answer already.

Thanks

I ran single pass encodes for ages. For the same file size, the quality difference is nothing short of astounding with 2 pass encodes. The big difference comes in scenes with movement, which single pass encode can't really process that well.

There's a really useful mencoder guide here.
