View Full Version : Xvid compression question

04-03-2008, 02:51 AM
I recently used Virtualdubmod to convert a VOB file to AVI/xvid..the vob file was 99MB and the xvid file was 82MB...although it looked great it isn't much of a reduction in size..

How then do you get a full DVD down to 700MB using xvid compression

You lower the bitrate/resolution until it fits :)
The easiest method is to get a tool such as AutoGK to do it for you.

If you lower the resolution then you can lower the bitrate also, however it wont look quite as sharp if you full-screen it :)

Using the newer h.264 compression (x264 is a good encoder!) you'll get better picture quality at the same bitrate vs XviD. Also, do a 2-pass encode for better quality at lower bitrates also :)

Yep, would recommend x264 too. Though most DVDs that have been compressed that much look pretty bad at full screen - 2 disc versions are usually ok.

Depends how big your screen is ;-)
Yep use AUTOGK 2pass - pretty much idiot proof.

1pass can do that - you end up with a file larger or similar to uncompressed original.
If im being fussy I prefer 1400mb. In IFO mode it will give you one avi output file.

Selecting the resolution will be done for you.If you have an ancient 2ghz P4 like me,it takes a few hours for a movie.

Most people will find 1 CD with a good 2pass fine.The problems appear when people use the FAST divx mode etc sacrificing quality for time.

264 is becoming more popular.I think Gordian Knot can use that.
I use WINFF on other stranger files.
