How do I change the size of a file?

[E_1]

This is my question:

If I have a DivX file and it's more than 700 megabytes, which is more than my CD I want to burn it on, how can I, without splitting it or making the movie shorter make the file become less than 700 megabytes?
Making the quality worse or something like that.

I've been banging my head on this one

Lower the quality of the audio, short of cutting parts of the movie.

Maybe this is a stupid question, but i am not very experienced:

How do I lower the quality of the audio?

1. Open file in Virtualdub.
2. Under Video tab, select Direct Stream Copy.
3. Under Audio tab, select Full Mode Processing and make sure that avi audio is selected. In the compression setting, choose MP3 and select the bitrate that will ensure that you get a smaller audio file (Generally 96kbps or lower, assuming your source is of higher bitrate). Take care of your interleaving settings too. You don't want to have the audio go out of synch. with the video. Check that the audio is not delayed (set 0 value).

Thanks for the help, but I still have a problem:

I came to changing to MPEG 3 , but then there's no option to change the bitrates. It is possible to change the bitrates for the other Audio Compressions.

Uhh...try installing Radium MP3 Codec and see if it helps.

Thanx, now it works. How did you know that
Doesn't matter, thanks a lot!

I had the same problem before too. One of my systems does not require it installed, but the other one needs Radium. Beats me why.

[E_1]

another problem....

When I change the compression as you told me, when I want to save the file it says on some movies:

"error initialising audio stream compression: the requested compression is not possible"

And does it matter for the file size if it's 48000 / 96bit or 41000 / 96 bit?

[Enchanter]

Others seem to like changing the frequency of the audio to something else, but I prefer keeping the frequency the same (eg. 48KHz source will still be encoded into 48KHz sound).

As for that message, it probably appeared because you instructed it to encode at a different frequency. Try encoding it at the same frequency.

Thank you for all the help! Now I'm doing great with reducing the file sizes of the large movie files.

Glad I can be of help.

Or you could simply use DIVX 3.11alpha fast motion 6000Bitrate as long as your original SOURCE IS HIGH QUALITY, you will not lose an quality, download this captured file and experiment for yourself:

(MPEG2 72.2MB)

It is not a good idea to reencode something that was encoded from something else. Performing encoding after encoding on a movie will only worsen its quality, much like copying music from tape to tape.

And I'm not really into using fast-motion codecs anymore, with the advent of SBC.

well u see, that is what many people say but it doesn't worsen the quality!!! The way I do it, makes fast motion good for some reason and I am proud of that + the fact that it reduces the file size is great!

Everyone has their own opinions!
