I have a bunch of ripped DVD's that are in VOB file, but I need a good and free way to convert these files to something smaller but remain the quality. Some friends suggest me transcode these VOB to DivX file, but I do not know how. I completely have no ideas about the formats divx, xvid, vob or mov. By chance I found a software called Aneesoft Video Converter Pro, it is entirely designed for me, I think. At first I just half-believed it and used its trial version. Once I show you why I so strongly recommend this software, I believe you will stand in my side!
This software is a free trial application that accomplishes this task quickly and easily. It even has iPhone/iPod/PSP preset format options to set up for different devices automatically. It is easy to use and converts the video in a single pass, ready for transfer and sync to your iPhone. Considering you might be a novice of computer, let me show you how to convert VOB files to DivX format step by step.
Things you’ll need
1. Aneesoft Video Converter Pro (Free for download trial version)
2. VOB video files
Step 1: Download & install Aneesoft Video Converter Pro
We’ll be using the very nice video converter software called Aneesoft Video Converter Pro for converting VOB videos to DivX format, head over here and download the free trial version. Next step is to install the program.
Step 2: Run Video Converter Pro and add DivX video files
Now run Aneesoft Video Converter Pro and click the big button "Add..." to add VOB video files on your computer, you may add as many videos as you want to convert to DivX videos. Only the titles you checked will be converted. So if there're some videos you don't want to convert, you need to uncheck them or 'Remove' them from the right-click menu. 'Clear' in the right-click menu means remove all titles in the list.

Step 3: Edit videos: crop, trim, add effects, add watermark
Wanna edit your videos to make it more personalized? You may add a watermark in Aneesoft Video Converter Pro. Just select the title you'd like to add watermark, then click the button 'Edit' to launch video editing window. If you want to crop video or add some special effects, click the first two tabs. You're able to add a text watermark or an image watermark (you may call it logo) on the output video. Adjust the 'Transparency' to make the watermark look better.

Step 4: Merge some separate VOB videos to 1 single DivX file
Click on the video titles you'd like to merge to 1 single file, then click 'Merge' button and uncheck the former separate files if you just need the single merged video file. Here 'click on the video titles' is not just check the options, you need to click them to make them highlight. You may see the image below to have an idea.

Step 5: Change the output settings to convert videos with best quality
Choose the most suitable DivX output format as you want. Besides to DivX format, there are almost all common video formats available for you to choose to convert. You may convert VOB videos to different video formats for video editing or playback on your mobile devices, such as iPod, iPhone, PSP, cellphone, etc. Remember that the output file size mostly depends on the Bitrate you set. Larger Bitrate, larger file size. Actually video with bitrate as 768 is acceptable for watching.

Step 6: Start converting VOB videos to DivX videos
Now you may click the big button "Start" to begin converting VOB videos to DivX videos. Once the convert is complete, Aneesoft Video Converter Pro will place a new version of your DivX video. Double-click the new DivX video file and play it to make sure it looks as you expect.
