Why Convert VOB to MP4?
VOB (Video Object) is the core container format found inside DVD-Video VIDEO_TS folders. VOB files contain interlaced MPEG-2 video, AC-3 multi-channel audio, and DVD menu structures. Since modern laptops lack optical drives and mobile phones cannot open VOB streams, converting VOB to MP4 deinterlaces the video and creates a single portable digital file.

Frequently Asked Questions
Does conversion remove jagged interlacing lines from DVD videos?
Yes! VideoReduce automatically applies hardware-level deinterlacing to eliminate comb-like horizontal scan lines from old DVD recordings.
How much smaller will the converted MP4 file be?
A 1GB VOB MPEG-2 file typically compresses down to 250MB–350MB in H.264 MP4 with equal or improved visual clarity.
What happens to the AC-3 5.1 Dolby Digital audio?
Our audio processor transcodes AC-3 audio into crisp AAC stereo or surround stream, fully compatible with mobile speakers.
Can I convert multi-gigabyte VOB files?
Yes. With local browser memory processing, you can convert full-length DVD VOB files with zero cloud upload waiting.
