Does converting VOB to MP4 lose quality?
VOB (MPEG-2) has to be re-encoded to MP4 (H.264). At "Balanced" quality the difference is very hard to see; choose "High" for footage you will edit again.
How long does it take?
Re-encoding video uses your device's processor. A short clip takes seconds; a 10-minute 1080p video can take several minutes. Choosing 720p makes it 2–3 times faster.
What is a VOB file?
VOB files store the video on a DVD, inside the VIDEO_TS folder. Each one holds MPEG-2 video with AC3 or MP2 sound and is limited to 1 GB, so a film is split across several VOB files. Home-made DVDs without copy protection can be converted; commercial DVDs are encrypted.
What is an MP4 file?
MP4 is a container that usually holds H.264 or H.265 video with AAC sound. It is built on Apple's QuickTime file structure and became an ISO standard in 2001. Because almost every phone, browser, TV and editing app can play it, MP4 is the safest choice when you need a video to just work.
