VOB file? What is this?

Why does my disk have a .VOB file?

Files with .VOB at the end are probably files taken from a DVD. In fact, a mac computer might even describe the kind of file as "mpeg-2," which is used for DVDs. VOB files are containers with more than just the video inside; VOB files contain information the DVD needs to play the video.

If you see a VOB file, you probably also see IFO and BUP. These files are also used by the DVD:

  • VOB is main package of video, called Video OBject. This is the file that needs converting
  • IFO is a summary of InFOrmation about the video. The DVD uses this to mark chapters, for example.
  • BUP is a duplicate of VOB, a BackUP file in case the VOB is damaged or corrupted.

VOB files need converting.

VOB files are very usable, but most of the time that VOB needs to be converted to a different type if you want to edit it or upload it to a video host.

Converting at the lab: iSkysoft iMedia Converter

In Computer Central at the CCTV studio, the favorite program to convert VOB (and other) files for use in editing programs is iSkysoft iMedia Converter. I highly recommend this program, and the Computer Central staff will be very glad to help you work with your video files. If you have the means to get to CCTV, it is worth the time spent!

Converting at home: FLV Crunch for Mac

However, today I wanted to work on a project at home, using an aged iMac. I can't download the iSkysoft program for free. The price is currently about $50. (Yet another reason to go to the lab!)

Because I wanted to try a free version, I carefully researched software reviews from reputable sources (the deal-clincher was CNET Download.com). I chose FLV Crunch for Mac.

Downloader Beware! Cheesy advertisement appears. Close the small box. Don't agree to anything. It isn't required for the download!

I chose to convert my 200MB VOB file
I selected MOV (Quicktime) as the format to convert to
It was converted to a 300MB .MOV file
It took less than 2 minutes

Voila! I opened the new .MOV in my video editing program, and I'm ready to edit!

The video shown is one of the files I worked with this way. It is made by AmyJo in Cambridge. In includes some classic book-related footage, then shows a Book Topple from 2011. Thanks, AmyJo!
