Generation loss — quality may degrade
VOB uses lossy compression, and so does MOV. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Some metadata may not survive
Your VOB file may contain DVD IFO data metadata. MOV has limited or no support for these metadata types. Location data (GPS), camera settings, and color profiles may be stripped during conversion.
What compression artifacts to expect
MOV lossy compression can produce codec-dependent (ProRes: minimal, H.264: blockiness). At the high quality settings CocoConvert uses by default, these are usually invisible to the eye. Lower quality settings trade visual fidelity for smaller file sizes.

About VOB to MOV Conversion
VOB (introduced 1996) and MOV (introduced 1991) are both video formats, but they differ in important ways. VOB is the DVD video format containing MPEG-2 streams, audio, subtitles, and menus. MOV is Apple's QuickTime container, commonly used by iPhones and professional video cameras.
Full Name: VOB uses DVD Video Object, while MOV uses QuickTime Movie. Compression: VOB uses Lossy, while MOV uses Lossy. Color Depth: VOB uses 8-bit, while MOV uses 8–10 bits (codec dependent).
When you convert VOB to MOV, the goal is to improve file compatibility across devices. VOB uses lossy compression, and so does MOV. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible. Understanding these technical differences helps you choose the right format for your workflow.
Your VOB file is decoded and re-encoded as MOV. The conversion involves 4 steps: (1) your vob file is uploaded and the format is validated, (2) the file content is decoded into its raw representation, (3) the data is re-encoded in mov format with optimal settings, (4) the converted file is ready for download.
CocoConvert's converter handles the entire pipeline server-side using FFmpeg, Sharp, and qpdf — battle-tested libraries used by streaming platforms and enterprise tools. Files are encrypted in transit and deleted within 24 hours.
This conversion is ideal when you Your VOB file won't open on a recipient's device or in an application, or when you A website, service, or platform only accepts MOV uploads. For the opposite direction, CocoConvert also supports MOV to VOB conversion.
How to Convert VOB to MOV
- 1
Upload .vob file
Select your VOB file by dragging it to the upload zone or using the file picker. Batch upload is available for multiple files.
- 2
Choose .mov
Set MOV as the output format. The converter uses optimal settings based on the VOB→MOV conversion profile.
- 3
Convert
The server-side engine decodes your VOB file and re-encodes it as MOV. Processing time depends on file size and complexity.
- 4
Download result
Grab your converted .mov file. Multiple output files can be downloaded together.
What Happens When You Convert VOB to MOV
Your VOB video is transcoded — video and audio streams are decoded and re-encoded into the MOV container. This is a lossy process that takes time proportional to the video duration.
Your VOB file is demuxed — video, audio, and subtitle streams are separated
The video stream is decoded frame-by-frame, then re-encoded with MOV-compatible codecs (typically H.264 for MP4)
The audio stream is decoded and re-encoded (or copied if the codec is compatible)
Subtitle and chapter data is preserved where the target supports it
Streams are muxed into the MOV container and the file is saved

Should You Convert VOB to MOV?
When to Convert
- ✓Your VOB file won't open on a recipient's device or in an application
- ✓A website, service, or platform only accepts MOV uploads
When NOT to Convert
- ✗You're converting just because the file "seems old" — re-encoding lossy-to-lossy always degrades quality
Common Mistakes When Converting VOB to MOV
"I'll convert to MOV and then back to VOB — it'll be the same"
Each lossy conversion cycle permanently degrades quality. Going VOB → MOV → VOB will produce a noticeably worse file than the original. Always keep your source file.
Frequently Asked Questions
What is the difference between VOB and MOV?
VOB is the DVD video format containing MPEG-2 streams, audio, subtitles, and menus. MOV is Apple's QuickTime container, commonly used by iPhones and professional video cameras. Full Name: VOB uses DVD Video Object, while MOV uses QuickTime Movie. Compression: VOB uses Lossy, while MOV uses Lossy. Color Depth: VOB uses 8-bit, while MOV uses 8–10 bits (codec dependent).
Does VOB to MOV conversion affect quality?
VOB uses lossy compression, and so does MOV. Converting means decoding and re-encoding — each cycle can permanently degrade quality. Convert from the original source file whenever possible.
Which format has better compression, VOB or MOV?
VOB uses lossy compression. MOV uses lossy compression. The better choice depends on whether you prioritize file size or quality.
How long does VOB to MOV conversion take?
Most conversions finish in seconds. Larger files or complex video content may take 10–30 seconds. CocoConvert processes files in parallel for batch jobs.
Is VOB or MOV better for long-term storage?
Both formats use lossy compression, so consider keeping your original source file for long-term storage.
