Need explaining of a few terms please

What I am talking about is referring to DivX 5

I have noticed that some movies with lower resolution look better than other divx movies with lower resolution. Bitrate deals with audio quality correct? The kbps confuses me though. My DivX version of Gladiator is 1.2GB! It has a fairly normal resolution 640x272 but the kbps is 127. Is that why the large file size?

Any help or links to a divx glossary would be great.

KBPS refers to kilobits per second. This can stand for both video AND audio. What it means is more data is available to show the video or hear the audio. Sorta like more bandwidth on your internet line. The higher the bandwidth the faster the internet connection and in the case of movies, better video and audio quality. Hears how to calculate bitrate to file size.



Add the video bitrate to the audio bitrate. divide by 8. Thats how many kiloBYTES per second your movie takes up. Hears an example using a video clip with a 300kbps video rate and a 56kbps audio rate

300 + 56 = 356
356/8 = 44.5KBps
or 44.5 kilobytes per second of the movie
1 minute would eat up 2.67MB.

Very True. If you DLL movies, you don't have to watch the size of the file that much, check the resolution... that will tell you much more

Some of those have high quality Video (High bitrate) but very low quality audio.. Great looking movies you can't hear you can boost the audio, thank goodness...

Speaking of boosting the audio, I have a dvd rip of Casino and the audio sucks. How do I increase the quality, vdub?

Audio > full processing mode
Audio > Volume

But also

Audio > Compression > Codec > same as source > bitrate

Otherwise it saves it uncompressed, if your converting to VCD/DVD/SVCD later you can also increase the audio there.

You could also save it out

Audio > > full processing mode
Audio > conversion > 44.1Khz
SAVE WAV

Then use www.goldwave.com to edit (Gold wave will also load audio from an AVI)

But check your ripper program, they may be a setting in there ?

I didnt rip it. It's a Kazaa download, If I had ripped it then it would be much better quality.

Ok well upping the volume works great but this is an mpg file not an avi file. Am I suppoed to put video on direct stream copy? Because I get this error when re-saving it. If I switch to video >> full processing mode, then the file size is huge.

"If I switch to video >> full processing mode, then the file size is huge. "

Video > full processing mode
Video > Compression > Codec > MP3 > Data rate

Would solve the size, however you said in this post

"What I am talking about is referring to DivX 5" so this cannot be a .mpg and must be an AVI.

Although Vdub will edit .mpg it can only save as AVI, so if you wish to keep it as a .mpg use TMPGEnc

"Speaking of boosting the audio, I have a dvd rip of Casino and the audio sucks. How do I increase the quality, vdub?"

If that is the file you are talking about, then in the ripping program it will have an audio gain when converting to mpeg
