Changing data rate of video (XviD)

[The Celestial Celebi]

Okay, I have here 5 videos.

1. episode_18.avi
Image: Width 640 x 480 pixels
Audio: 0:22:49, 128 kbps, MPEG Layer-3
Video: Frame rate 23, data rate 127 kbps, 24 bits, XviD

2. episode_35.avi
Image: 640 x 480 pixels
Audio: 0:22:50, 128 kbps, MPEG Layer-3
Video: Frame rate 23, data rate 149 kbps, 24 bits, XviD

3. episode_38.avi
Image: 640 x 480 pixels
Audio: 0:22:59, 128 kbps, MPEG Layer-3
Video: Frame rate 25, data rate 130 kbps, 24 bits, XviD

4. intro.avi
Image: 640 x 480 pixels
Audio: 0:01:07, 192 kbps, MPEG Layer-3
Video: Frame rate 23, data rate 576 kbps, 24 bits, XviD

5. outro.avi
Image: 640 x 480 pixels
Audio: 0:01:03, 192 kbps, MPEG Layer-3
Video: Frame rate 23, data rate 416 kbps, 24 bits, XviD


Phew, that was a lot of typing..

Well, here's my problem: I want to convert them all to this:
Width: 640 x 480 pixels (no need to change)
Audio bit rate: 128 kbps (only change for the intro and outro)
Audio format: MPEG Layer-3 (no need to change)
Video frame rate: 23 frames/second (only change for episode 38 )
Video data rate: For all episodes 133 kbps (and for the intro and outro I want them in 133 AND in 137 kbps, so I get in total 4 files from them)
Video sample size: 24 bits (no need to change)
Video compression: XviD


I want to keep them XviD, not DivX. If I reencode them to DivX I can specify the filesize (they must all become 175 MB, except for the intro and outro) and everything goes fine (I think), but for XviD I can't specify anything.. Only some target quantizer and if I click on it, the bit rate of the video.. I don't get it at all.


Can someone please help me on changing the datarate of the files? I want them all 133 kbps. And for episode 38 I want the framerate 23 instead of 25.
The files (except for the intro and outro) must all become around 175 MB, so I can fit 4 of them (I have DVD rips which are 175 MB) on a CD.


Thanks in advance and I hope everything is clear.. I'm Dutch and not good at English. :P

Everything is clear to me ... the guides section is where you should be looking

Virtualdub can do everything for you. There's really wayyy too many options and features for me to discuss in a thread, so you'll just have to read, read, read - I'd suggest these guides as a good starting point

[The Celestial Celebi]

Yay, so it really can be done?
That's awesome
I already got some help from a few users on a IRC channel...


But.. Where to change the data rate then? I didn't find any place on where to change it (it's a XviD, it has that line greyed out)

With DivX it's no problem.


/me goes reading those guides.

This guide... That's what I need, but then not for DVD 2 AVI, but for AVI 2 AVI :P

I'm going to start encoding.. Thanks for the link! *hopes it works*


But.... I used that before, kinda the same. Put the size (179200 kB) in there, but got a file of 400 MB. ;x

Anyway, I'm just going to try it again, with that guide..... I'll let you know if it worked or not

"they must all become 175 MB"

Why ?

[The Celestial Celebi]

Because.. I have episodes of a certain serie, and all episodes are 175 MB.
Only those 3 (the ones above, they are banned and I found the Japanese versions of them), are bigger or smaller.

4 x 175 MB = 700 MB... So I can fit 4 of them on one CD.

Maybe my question sounds weird.. But that's really what I want to do

Any of the guides in that link I posted can do the job - the secret is that you already have an AVI, so you can skip about the first three quarters of most of them (this is just where they go through converting the source to a format virtualdub can accept), and start at the part where a file is loaded into virtualdub or one of its variants. Your bitrate controls the filesize, so if you want to hit a target size, use a bitrate calculator to give you the values you need.
