MOV to VOB Converter

What happens when you convert MOV to VOB

• The video is re-encoded to MPEG-2 video with Dolby Digital (AC-3) audio at 48 kHz, the streams a DVD uses.
• Re-encoding in a browser is slow: expect several times the video's length for HD footage on a laptop, and longer on a phone. Short and low-resolution clips finish much sooner.
• The picture keeps its size, and frame rates other than 25 and 29.97 are changed to the nearer one, because DVD video only has those two. A set-top DVD player also needs 720 by 576 (PAL) or 720 by 480 (NTSC) inside a disc structure, so to burn a DVD, give the VOB to DVD authoring software such as DVDStyler.

How to convert MOV to VOB online

1. Press "Choose MOV files" and select one or more files, or drag them onto the box. You can add files of any size your device can hold in memory.
2. Adjust the settings if you need to: resolution and quality control the size of the result. The defaults suit most people.
3. Press "Convert to VOB". The first audio or video conversion downloads the converter engine, about 32 MB, which your browser then keeps for next time.
4. Save each VOB with its download button. Close the tab and every trace of the files is gone from memory.

Why convert MOV to VOB?

MOV files usually come from iPhone recordings, Final Cut Pro and screen recordings on Mac. People convert them to VOB because VOB is the file type DVD authoring software and DVD players work with.

In short, MOV is good at what it was made for, and VOB is the more practical choice when the file has to play, upload or edit somewhere else. MOV plays in Safari; Chrome plays most MOV files that use H.264, while VOB does not play in browsers; plays in VLC and DVD software.

How to convert MOV to VOB on Windows, Mac, iPhone and Android

On Windows

Open this page in Chrome, Edge or Firefox, drag your MOV files in from File Explorer, and press Convert. Each VOB is saved to your Downloads folder. If you prefer a desktop program, VLC can also convert MOV to VOB: choose Media, then Convert / Save.

On a Mac

Safari, Chrome and Firefox all work. Drag the MOV files from Finder onto the drop zone and the VOB files land in Downloads.

On iPhone and iPad

Open the page in Safari and tap Choose MOV files. You can pick from Photos or from the Files app. The converted VOB appears in Files, in the Downloads folder; to put it in your photo library, open it there, tap Share and choose Save Video. To stop the iPhone creating MOV files in future, go to Settings, Camera, Formats and choose Most Compatible.

On Android

Open the page in Chrome, tap Choose MOV files and pick them from Files or your gallery. The VOB is saved to the Download folder, where any file manager can find it. Keep the screen on while a long video converts, because Android may pause a tab in the background.

Best settings for MOV to VOB

VOB is written as MPEG-2 video with Dolby Digital (AC-3) audio at 48 kHz, the streams a DVD uses. The Resolution setting is the one to reach for: 1080p keeps full HD detail, 720p is plenty for phones and laptops and roughly halves the size, and 480p suits email and old devices.

The quality levels map to the H.264 CRF scale where the target uses H.264, and to fixed high-quality settings for older codecs such as MPEG-2, MPEG-4 Part 2, WMV and Theora. Re-encoding always costs a little detail, so convert from the best copy of the MOV you have.

MOV vs VOB: the differences

About MOV and VOB files

What is a MOV file?

MOV is the QuickTime container that MP4 was based on, so the two are close relatives. iPhones record MOV, and newer iPhones use HEVC inside it, which Windows and many websites cannot play.

What is a VOB file?

VOB files are the video chunks inside a DVD's VIDEO_TS folder, each capped at 1 GB, so one film is split across several. Commercial DVDs are encrypted and will not convert; home-burned discs will.

MOV to VOB not working? Common problems

• The conversion is slow. Audio and container changes take seconds, but re-encoding video runs on your own processor. Lower the resolution to 720p, close other tabs, and keep the device plugged in.
• The tab stops or reloads on a very large file. Browsers limit how much memory one tab can use, around 2 GB and less on phones. Split long recordings or convert them on a computer.
• The VOB will not play on an old device. Try the other formats offered for MOV, or choose 720p, which older players handle more reliably.

Convert MOV to VOB with ffmpeg

This converter runs ffmpeg inside your browser. If you would rather use the ffmpeg command line on your own computer, this command produces an equivalent VOB with the same kind of settings:

ffmpeg -i input.mov -c:v mpeg2video -q:v 3 -c:a ac3 -b:a 192k -ar 48000 -f vob output.vob

Replace input.mov with the name of your file. For a whole folder of MOV files, run the command in a loop, or drop them all on the converter above, which processes them one after another.
