VOB (Video Object) is the primary data format used on DVDs. Each VOB file contains a portion of a DVD's video, audio, and subtitle data, typically up to 1GB in size. If you've ever ripped a DVD, you've encountered VOB files in the VIDEO_TS folder. VOB uses MPEG-2 encoding, which is far less efficient than modern H.264.
VOB files tend to be large (1gb per segment) compared to optimized MP4. Converting from VOB to MP4 H.264 typically reduces file size by 40-80% while maintaining excellent visual quality. The resulting MP4 also plays on every device and platform without compatibility issues.
VOB was developed by DVD Forum in 1996. It uses the DVD Video Object container and typically contains MPEG-2 encoded video. Browser support is none, and mobile support is requires vlc. For streaming, VOB offers no capabilities.
Keep VOB if you're doing professional editing and need the original codec quality. Convert to MP4 when: you need to share the video online, upload to social media, send via email, or reduce storage usage. For 99% of sharing and consumption purposes, MP4 is the better format.

When you upload a VOB file, SquishVideo first analyzes the video stream to understand its codec, resolution, framerate, and bitrate profile. We then transcode the video to H.264 MP4 using optimized encoding parameters. The entire process preserves audio quality (re-encoded to AAC) and maintains the original resolution unless a lower resolution would provide a better quality-to-size ratio.
VOB files typically come from: DVD rips (VIDEO_TS folder), DVD authoring software, and DVD backup tools.
