How to Reduce a DIVX movie size (.avi)

[newyork2000]

I already have in my computer some .avi divx files and I would like to know what do I have to use and how to use it to reduce the whole size jsut to fit on one only CD.
I don't need to convert it in vcd or svcd, just make the entire movie fit on onw cd without cutting it into two separate parts.
Thank you

If its only just slightly too big to fit on one cdr then you can try cutting off the end credits. If you don't want to do that , or its too big for that, you can try re-encoding the audio to a lower bitrate...if that still isn't enough then you will have to re-encode the video to a lower bitrate. Virtualdub can do all of these things.

ciao
grazie della risposta.
Mi spieghi meglio cosa devo fare in virtualdub per ridurre il filmato alla dimensione diun CD, cioe' praticamente quei 700 e rotti MBs?
Ho iniziato ad usare da poco Virtualdub ed ho imparato per ora a tagliare i films ma non sono ancora capace a ridurli.
Ho cmq capito che devo ridurre il bitrate, quoindi decidere di perdere qualita' o nell'audio o nel video o.. in ambedue. Ma come devo effettivametne operare?
C'e' una guida qui in questo sito? non ne ho viste.. fammi sapere.
Grazie

Pardon?

Sorry. I assumed you were italian by your name.
I thanked you for the quick reply and I also wnated to ask you for more informations.
What do I have to do with Virtualdub to reduce the movie to fit a cd, normally about 700 or so MBs?
I'm using Virtualdub from a few and up to now I only can cut movies in two parts, but I'm not still able to reduce the size acting on bitrates.
I already know that reducing the bitrate turns into losing something in audio and/or video either. But, how do I actually ahve to manage it?
Can I find a guide or something alike here around or will you be so kind to instruct me a step by step of?
Thank you again in advance.
Joe

No I'm not italian ....my name is a character from a British Tv comedy show.

Try this guide:

https://www.videohelp.com/avi2divx.htm

It tells you how to reduce the bitrate for both audio and video. I'm not sure if you need to bother with all the filters and other things it mentions...just the bit about re-encoding at a lower bitrate.

If you only want to reduce the size a little then try just reducing the audio bitrate...if you need to reduce the file size a lot then you'll have to lower the video bitrate too....you will lose a certain amount of quality of course, but even a 2 hour movie encoded at a bitrate to fit on a single cdr will still look pretty good.

you can also overburn if your CD-R drive lets you do it. I know that Nero has some options on overburning.

[newyork2000]

I have Nero...
How can I overburn?
CAn you tell me the procedure?

That works if converting to VCD, the original post said that he's keeping it as an Avi.

[newyork2000]

Thank you.
I found the document really interesting... though I ahve one more question.
In the pdf they say I have to change the capacity of the cd according to its capacity.
Does tht mean that I I cannot overburn cdr80-700MBs with more?
From what I understood I should then buy for a larger capacity cd. Right?
Thanks again

Thank you for your reply.
My only concern is that maybe this guide is good when I start from zero, that means when I want to rip and burn a DVD...
My problem is that I have a divx file (.avi) ready to be burnt...
Is the procedure and the software used in the guide of help the same for me?

Try this. It works for me.

Sorry I gave you the wrong guide this is the one that you need:

I hope this will help you

[newyork2000]

Ok, but my last question is.
Do I have to use 99min. CDs or may I reach my goal with a standard 80min. CD?

You can overburn on a regular 80min CDs. But if you have 99min CDs than you don't have to overburn. Now if you use 80min CD I don't you'll be able to overburn lets say 800 Mb on it, but I'm sure you can overburn up to 15 MB and maybe more. If I had 99min CDs than I would not overburn because if you overburn all the time you'll eventually screw up your CD-R drive.

[newyork2000]

Is it dangerous overburning 8omin CDs?

it is not dangerous, but I would prefer splitting the movie and using two CDs, cause CDs are really cheap right now. But if you really have no choice but the put it on one CD than do it. But try not to overburn every single movie you have. If you do it once in a while I don't think that anything is going to happen. I've been working with movies for more than 3 years now, and I never had to overburn any movie. I usually make VCDs and they always seem to fit perfectly on 2 CDs. And another thing is that I always use CD-RWs because when the VCDs get boring and old I just erase the CD and put another one on. So I never buy any CD-Rs to use for movies. I have about 40 CD-RWs and I'm using them for more than 2 years. I buy CD-Rs and I use them for music because I know that I'll always listen to that CD, or for data. But for movies I always use CD-RWs.

VCD/SVCD are burned in Mode 2 mode which can fit 800 MB on a 80 min CDRs. You can fit more with Mode 2 because there's no error correction being used.

So, if your AVI files are near 800 MB, you can try burning in Mode 2 mode. With overburning you can fit about 820-830 MB on a typical 80 min CDR.

If your AVI is about 800 MB, you can use VCDEasy to create a Bin and Cue file containing the 800 MB AVI file.

If your AVI files are larger than 830 MB, you can either try using a 90-99 min CDRs but those are expensive and not very compatible with CDROM readers and CD Burners so I would either split your AVI onto 2 CDRs or apply some noise reduction filters and recompress your AVI file with Divx 3/4/5 codec to fit onto 1 CDR.
