FAQs

💬 You are here because you have questions like:

What's the best way to convert old .vob format video to .mp4 or other?

How do I convert a VOB file to mp4 while retaining pretty much the exact same quality (no compression)?

I have a 18 GB folder with .VOB files. Is there any way I can convert it to .mp4 to reduce the space it occupies?

VOB files are DVD video media files with the .VOB extension. They are often found in the VIDEO_TS folder at the root of a DVD, alongside .BUP and .IFO files.

Due to limited compatibility and large file sizes, you may find VOB files difficult to handle. If you're looking to play them on modern devices or save storage space, converting VOB to MP4, the most widely supported format, is a great solution.

Note that because of the special structure of DVD VOB files, especially when using DVD encryption, a dedicated VOB converter is required. So in this guide, I will share a powerful VOB to MP4 converter and show you how to convert VOB to MP4 on your Windows PC. Plus, I will explain how to use HandBrake as a free alternative for converting unencrypted VOB to MP4. Let's get started!

Next, I will demonstrate how to use this VOB converter to convert DVD VOB to MP4 and individual VOB to MP4.

Download this VOB converter and install it on your PC first:

- Case 1: Convert DVD VOB (VIDEO_TS) to MP4

This method is suitable for converting VOB files (e.g., VTS_01_1.VOB, VTS_01_2.VOB, etc.) within a VIDEO_TS folder. Before start, download and install download and install the recommended VOB to MP4 converter.

Step 1: Load the DVD Folder

Launch the software. Since the VOB files you want to convert are inside the VIDEO_TS folder, simply click the ▼ button next to Load DVD and select Load DVD Folder. Navigate to the parent DVD folder and click OK to load all the DVD VOB files.

💡 The main title is auto-selected after loading. If you want to convert other titles, which are often commentary, ads, or behind-the-scenes, you can manually select them. Check the box before Merge all videos into one file at the bottom if you want to export them as a single file.

Step 2: Select the MP4 Format

Click on the format image on the right of the conversion window to open the output format library. Under the Video tab, select MP4 as the output format.

You can also select other formats or directly set the device you are using as the output profile. Its Smart Fit feature will choose optimal output settings based on your format selection.

💡 For advanced conversion needs, you can open Settings to customize the output parameters like codec, resolution, aspect ratio, and more. If the source movie shows horizontal motion lines during playback, be sure to check Deinterlace to remove these lines for better viewing experience.

Step 3: Start the Conversion Process

Finally, hit the three dots to set a new output folder (ensure it has enough free space) and click Run to start converting your DVD VOB files to MP4 immediately.

🔔 The software supports hardware acceleration, which is enabled by default. If your computer has a compatible GPU, conversion speeds will be very fast. For example, on a computer equipped with an NVIDIA GeForce GTX 750, converting a 1 hour and 44 minute movie to MP4 format using H.264 encoding (default settings) takes approximately 4 minutes with GPU acceleration enabled and about 12 minutes when it's off.

- Case 2: Convert Individual VOB to MP4

This method is suitable for converting standalone VOB file, such as the ones downloaded from the internet. Before start, download and install download and install the recommended VOB to MP4 converter.

Step 1: Add the Individual VOB Files

Run the software and click Add Files at the upper left to import your VOB files. You can also straightly drag and drop them into the program. This tool allows batch processing.

Step 2: Choose MP4 as the Output Format

Enter the right-side format library, head to the Video category and select MP4. Alternatively, you can choose the H264 profile (which uses .mp4 by default) for best device compatibility, or the H265 for MP4 profile for smaller sizes while maintaining quality.

💡 Tweak the parameters in Settings if needed.

Step 3: Export the Final File

Choose a file destination at the bottom and hit Run to export VOB to MP4.

Convert VOB to MP4 with HandBrake (For Unencrypted VOBs)

HandBrake is a well-known open-source video transcoder that can convert various videos to MP4 format. If your VOB files are homemade or unencrypted, you can also use this free program to convert them to MP4 effectively. Here is how to use HandBrake to convert unencrypted VOB files to MP4:

⚠️ Note: HandBrake cannot process copy-protected DVD files. If you encounter errors like No Valid Source Found, it means the VOB file is encrypted. In this case, you must use Method 1.

* Ensure you have the latest version of HandBrake installed before proceeding.

Step 1: Launch HandBrake. You can click Open Source > Folder (Batch Scan) to import a VIDEO_TS folder, or File to load a single VOB.

🔔 HandBrake cannot intelligently recognize the main title when importing a folder, so you will need to check and select it manually. Typically, the title with the longest duration is the main movie.

Step 2: In the Summary tab, select MP4 as the output format.

Step 3: Click Browse to define the output path and rename your file. Make sure the video ends with .mp4 extension.

Step 4: Click Start Encode at the top to start the VOB-to-MP4 conversion in HandBrake

FAQs

1. Can I convert from VOB to MP4 file without loss of quality?

Converting VOB to MP4 involves re-encoding, which inevitably leads to a loss of image quality. But you can minimize the loss by using advanced encoders like HEVC/H265, which can compress videos while preserving quality close to the original.

Alternatively, you can convert VOB files to MPG (MPEG-2) format, thus completely avoiding quality loss.

2. What is the best free program to convert VOB to MP4?

HandBrake is widely considered the best free software for converting VOB to MP4. But it only supports non-copyrighted files. VOB files from commercial DVD folders must be converted using a professional VOB converter such as WonderFox DVD Video Converter.
