About VOB to MP4
What is VOB?
VOB (Video Object) is the container format used on DVD-Video discs, based on the MPEG-2 standard. VOB files contain MPEG-2 video, audio (AC3/MPEG-2), subtitles, and DVD menu data. You'll find VOB files in the VIDEO_TS folder when you rip a DVD to your computer. Individual VOB files are limited to 1GB each, so a movie is split across multiple VOB files (VTS_01_1.VOB, VTS_01_2.VOB, etc.).
Why convert to MP4?
DVD's MPEG-2 format and VOB container are outdated — most modern devices, phones, tablets, and streaming platforms don't support VOB playback. Converting to MP4 creates a single, compact video file that plays everywhere. H.264 compression also reduces file size significantly compared to MPEG-2, so a 4.7GB DVD can fit in a 1-2GB MP4 at comparable quality.
What to expect from the conversion
VOB's MPEG-2 video is transcoded to H.264, dramatically improving compression efficiency. File sizes decrease by 50-70% while maintaining or improving visual quality. DVD resolution (720x480 NTSC or 720x576 PAL) is preserved. Audio is converted from AC3/Dolby Digital to AAC stereo. Subtitles embedded in the VOB are typically not carried over — they'd need separate extraction.
How FluidConvert handles it
We process individual VOB files, transcoding the MPEG-2 video to H.264/AAC in a modern MP4 container. Upload the specific VOB file containing the video content you want to convert.

Frequently Asked Questions
How do I know which VOB file to convert from a DVD rip?
In a DVD's VIDEO_TS folder, the main movie is typically the largest VOB files — VTS_01_1.VOB through VTS_01_x.VOB. Small VOB files (under 100MB) are usually menus or extras. Convert the largest VOB files for the main content.
Can I combine multiple VOB files into one MP4?
This converter processes individual VOB files. To combine multiple VOB segments into a single continuous MP4, you'd need to concatenate the VOB files first or convert each separately and join the MP4s afterward.
Will DVD subtitles be included in the MP4?
DVD subtitles are stored as image overlays in VOB files and typically don't carry over to the MP4 as text subtitles. For subtitled content, you'd need to extract subtitles separately using a DVD ripping tool.
