How to Significantly Compress VOB Files - About 80% Space Saving

Author by Oswald

VOB is a container format that holds video data of your DVD. Mostly, there are multiple disordered VOB files in a DVD folder, every one of them is large in size which makes a single DVD movie take too much of your drive storage. To solve that, I’ll introduce you a decent tool that can significantly compress VOB files at a about 5:1 compression ratio and export a single video with complete and coherent movie content for the convenience and handiness of storage & playback.

You can download the recommended VOB compressor here to save your time.

Q: I'm doing a project and I have 8 VOB files each file over 1 GB. All together the files exceed 8 GB. I want to merge these files together into one and reduce the file size because it's extremely large (and perhaps convert to MP4). Thanks in advance.

A: That’s a frequently asked question from the users who have ripped their DVDs to digital backups. When it comes to VOB files, mostly refer to a VIDEO_TS folder containing multiple VOB, IFO, BUP files rather than the VOB video(s) solely. VOB, IFO and BUP files compose the complete Directory Structure of the DVD folder and are indispensable if you want to keep data intact - which consequently results in the fact that, to compress DVD files, the right move is to compress the entire VIDEO_TS folder but not just the VOB files.

It’s not as sophisticated as it might sound, if you pick the right tool. Here’s a decent one I recommend: WonderFox DVD Ripper Pro. It’s a top-rated and well-received DVD processing tool that can rip your DVD video with original quality preserved and, furthermore, shrink VIDEO_TS folder with unnoticeable video quality loss. Besides, with the help of it, you can easily sort out the messy, scattered DVD files, single out the main title, and even convert it to a single video with the full movie plot. 300+ output formats and devices are supported including MP4, MOV, WMV, AVI, iOS/Android devices, HD TV, etc. In the following, I’ll show you the detailed steps on how to compress VOB files, or rather, compress VIDEO_TS folder with WonderFox DVD Ripper Pro.

How to Compress VOB Files with WonderFox DVD Ripper Pro

Load VIDEO_TS folder into the program

Before start, please free downloadfree download the software.

Step 1. Load VIDEO_TS Folder into the VOB Compressor

Launch WonderFox DVD Ripper Pro. At the main workplace, you can define the destination path at the “Output Folder” box. Then click on DVD folder button to import the whole VIDEO_TS folder to the program. The main movie(s) will be highlighted and automatically selected after the analyzation, make sure you’ve selected it before further procedures.

Tips: Manually select all the Main titles neglecting Warning message, if your VIDEO_TS folder is a TV series, workout video set, or anything with multiple main titles.

Compress VOB to MP4

Step 2. Compress VOB files to MP4

Now we can customize the output file format. The recommend move here is to convert VOB to MP4 since MP4 format features the best compatibility, preferable quality, and what’s more, much better compression that brings about much smaller file size. Click on the output format section on the right side of the interface, select MP4 format from the “Video” category.

Sure, you can also convert VOB to any other preferred video format by clicking the corresponding icon. Converting VOB to android, for instance.

Start the VOB Compression

Step 3. Start the Compression Process

Before that, you can transcode your video to an advanced encoder to reduce video size even further, like transcoding DVD to H.265, which enhances video quality as well. If needed, hit the small “Settings” button at the lower-right side of the interface. Note that the compression process gets longer if you do that.

Hit “Run” when it’s all set.

Wrap-up…...

I hope you have learned how to compress VOB thoroughly. For those who really want to shrink DVD files but are still hesitant, WonderFox DVD Ripper Pro definitely won’t let you down – As mentioned previously, not just a VIDEO_TS compressor, the program is also a VOB merger that rearranges and joins the scattered VOB files automatically, so a single compact file is what you’ll get and an output, I believe that you’ll dig that. Do enjoy.
