How do I convert a video from one format, in this case a .vob into another, say .avi?

I have a DVD of 4.2 GB and would like to convert that to a smaller filesize and different format of an .avi file of around 700 MB.

I'm working on a Windows XP machine.

I'm very happy with Handbrake, an open-source, GPL-licensed, multiplatform, multithreaded video transcoder, available for MacOS X, Linux and Windows. VLC is another good option.

What is the average speed when you are converting with Handbrake? I'm converting .vob (4,2 GB) to .avi. What should be the size of .avi and the average speed while converting? – MladenB Sep 18 '09 at 14:16

For video conversion of all types, the common favourite is Handbrake. Not only will it support most filetypes (it even has nice presets for common media players, such as iPod, PSP, Apple TV etc), it is available for most platforms.

Is this wrong? Why the down vote? – Josh Hunt Sep 17 '09 at 14:30
+1 from me, Handbrake rocks :) – BenA Sep 17 '09 at 15:02
I'm assuming someone ignorant saw a Mac screenshot and thought you didn't realize the part about Windows XP in the original question, even though handbrake has Windows builds. – John T Sep 17 '09 at 16:22
I hate the fact that no one bothers explaining why they downvote. It drives me crazy. – alex Sep 17 '09 at 16:31
I hate the fact I take down votes so seriously – Josh Hunt Sep 17 '09 at 20:27

The gold standard in video encoding/conversion is two tools:

FFMpeg and MEncoder.

If they can't do it, it probably can't be done. Most of the GUI tools around are based on one of these two libraries (in fact MEncoder is itself partly based on FFMpeg). They both support decoding encoding and recoding pretty much every video format under the sun. They are also both open source and free and have been ported to most platforms (including xp).

The disadvantage is that they are both command line tools and have a learning curve about as steep as a mile high concrete wall, so they don't really fit your "something that beginners can easily use" requirement. I Thought I'd post them here in case you wanted to do something a bit more specific. (The MEncoder website does have a list of GUI front ends for various tasks.)

Could the down-voter please leave a comment as to why. – harrymc Sep 17 '09 at 18:44
I'm giving you +1 because of No 7, it contains my language :) – MladenB Sep 17 '09 at 19:01
How do I say "thanks" in your language? – harrymc Sep 17 '09 at 19:12
Hvala :) Thank you and others, now I have work for few days to see which one is the best for me. – MladenB Sep 17 '09 at 19:14

I'm unable to download with this link, are you sure about it? – MladenB Sep 17 '09 at 14:51
sorry about that, edited the post. while the link was correct, it doesn't work this way. you'll have to find the way to the download link youself, it's 3 clicks from the home page (1. Start downloading super, 2. download and use, 3. Download Super setup file). what were they thinking? :) – Molly7244 Sep 17 '09 at 15:03

Give Avidemux a try, it's a nice GUI approach which uses FFMPEG as the backend.

WinFF is one of the best GUI front-ends to FFMpeg for Windows.
