This Christmas as I wished, "Santa Claus" sent me a mobile phone which I expected for a long long time! I immediately downloaded some movies and songs from internet into it, but it supports only 3GP video format, so I needed to convert such vob file to 3GP file. I asked others on answers.yahoo.com, they gave me some links or provided me some converters. I tried some of them but the result was not good enough. Later my classmate let me tried the full version of Aneesoft Video Converter Pro (he bought it 2 months ago), it's just amazing. Easy to use, high quality, and I can also edit the videos as I want. As the price is reasonable, now I want to buy one myself. If you have the same question as I was, I'm quite willing to help you with my experience of how to use this marvelous software.
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 3GP 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 VOB 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 3GP 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 VOB 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 3GP 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 3GP output format as you want. Besides to 3GP 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 3GP videos
Now you may click the big button "Start" to begin converting VOB videos to 3GP videos. Once the convert is complete, Aneesoft Video Converter Pro will place a new version of your video. Double-click the new 3GP file and play it to make sure it looks as you expect.
