What is VOB and Why Convert to MP4?

What is VOB?
VOB (Video Object) is the DVD video format used on physical DVD discs. VOB files contain MPEG-2 video with AC3 (Dolby Digital) audio.
Modern laptops, tablets, phones, and streaming platforms do not support VOB playback. Even finding a device with a DVD drive is increasingly difficult.
What is MP4?
MP4 is the universal video format. Converting your DVD library to MP4 makes it playable on any device without needing a DVD player.
MP4 with H.264 encoding is compatible with every smartphone, tablet, smart TV, and computer made in the last decade.
