Why Trim VOB Files?

VOB (Video Object) is the container format used on DVD-Video discs, storing MPEG-2 video with AC3 or DTS audio. A typical DVD contains multiple VOB files, each up to 1 GB, holding movie chapters, menus, and extras. Trimming VOB files lets you extract specific scenes, remove unwanted content, or isolate individual chapters from DVD rips — without converting to another format.

This is useful for extracting favorite scenes from DVD collections, removing trailers or FBI warnings from ripped DVDs, isolating specific chapters for re-authoring, or reducing file size by cutting unnecessary footage.

Common VOB Trimming Scenarios

Scenario	Start Time	Duration	Notes
Skip FBI warning + trailers	120s (2 min)	Remaining	Skip first 2 minutes
Extract single chapter	Chapter start time	Chapter length	Use DVD chapter timestamps
Create highlight clip	Scene start	30–120s	Short clip for sharing
Remove end credits	0s	Movie length minus credits	Keep movie, cut credits

Frequently Asked Questions

What is VOB format?

VOB (Video Object) is the DVD-Video container format. It stores MPEG-2 video with AC3 (Dolby Digital) or DTS audio, plus subtitles and menu data. VOB files are found in the VIDEO_TS folder of DVD discs and rips.

How do I specify trim points?

Under "Trim," select "Time Range" and enter start time and duration in seconds. For example, start at 120 with duration 5400 extracts from 2:00 to 1:32:00.

Can I compress while trimming?

Yes. Under "File Compression," choose any method — quality preset, target file size, CRF, or bitrate. Trimming + compression in one step is more efficient than separate operations.

Will trimming affect DVD chapter markers?

Trimming re-encodes the video, so original DVD chapter markers, subtitles, and menu data are not preserved. The output is a plain VOB video file.

Should I trim as VOB or convert to MP4?

For DVD re-authoring, keep VOB. For general sharing and playback, consider VOB to MP4 — MP4 is universally compatible and more efficient.
