MPG is a generic MPEG program stream — usually MPEG-1 or MPEG-2 video — that plays almost anywhere. VOB (Video Object) is the specialized MPEG-2 program stream that DVD-Video discs use, with extra navigation and stream rules baked in. Converting MPG to VOB re-wraps (and, when the source is MPEG-1, re-encodes) your footage into the DVD-spec MPEG-2 form that DVD authoring tools expect. Note that a bare .vob is not a finished DVD on its own — see the FAQ below for what else a playable disc needs.

How to Convert MPG to VOB
- Upload Your MPG File: Drag and drop or click "Add Files" to select one or more MPG / MPEG clips — old camcorder captures, TV recordings, or ripped program streams. Batch upload is supported, so you can queue several clips for one disc in a single pass.
- Pick a Quality Preset and DVD Audio: VOB is locked to MPEG-2 video by the DVD-Video spec, so that codec is the default here. Audio defaults to MP2 (the universal DVD stereo track); AC-3 (Dolby Digital) and DTS are also available for surround. Choose a Quality Preset (the default is "Very High (Recommended)"), or open File Compression to set a Constant Bitrate in the DVD-friendly 4–9 Mbps range, a Variable Bitrate for size efficiency, or an exact file size in MB.
- Set Resolution or Trim (Optional): Pick a preset resolution — 480p maps to the 720×480 NTSC frame, 576p to the 720×576 PAL frame DVD players expect — or enter a custom Width × Height. Use Trim with a start time and duration to drop intros or split a long capture into chapter-sized pieces before authoring.
- Convert and Download: Click "Convert" and download your VOB file. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark.
Frequently Asked Questions
Is a VOB file by itself a playable DVD?
No. A .vob holds the multiplexed MPEG-2 video and audio, but a DVD player also needs the navigation structure — the VIDEO_TS folder with its .IFO (information) and .BUP (backup) files — to know how to find and play titles. This converter produces the VOB stream; to make a disc that plays in a set-top DVD player, load the VOB into DVD authoring software (such as DVD Flick, DVDStyler, or ImgBurn) to build the full VIDEO_TS structure, then burn it.
Does converting MPG to VOB improve quality?
No conversion can add detail that the source never captured. If your MPG is already MPEG-2, the move to VOB is mostly a re-wrap and stays visually close to the original. If the source is MPEG-1, the step up to DVD-spec MPEG-2 is a genuine re-encode — it makes the file DVD-compatible but cannot recover the resolution or sharpness MPEG-1 left out. Keep the bitrate generous to avoid adding compression artifacts on top.
Why is the audio MP2 instead of AAC?
The DVD-Video spec does not allow AAC or MPEG-4 audio in a VOB. The legal options are MP2, AC-3 (Dolby Digital), DTS, and linear PCM. MP2 is the safe default for stereo playback on any DVD player; choose AC-3 if you want Dolby Digital surround that matches what commercial discs ship with.
Should I pick NTSC (480p) or PAL (576p)?
Match the region of the player you plan to use. NTSC (720×480) is standard in North America and Japan; PAL (720×576) is standard across most of Europe, Australia, and parts of Asia. Most modern players and ripping tools handle both, but a region-correct frame avoids vertical scaling and keeps motion smooth.
Why might my VOB get split into multiple files?
DVD VOB files are typically capped near 1 GB each so they stay readable on file systems that cannot handle larger files. Long footage is therefore broken into several sequential VOBs during authoring (VTS_01_1.VOB, VTS_01_2.VOB, and so on). That is expected behavior, not corruption — the authoring software stitches them back into one continuous title on the disc.
How large a file can I convert, and is it private?
The practical limit is upload size and time rather than your hardware, since processing happens on our servers. In our testing, a 5-minute MPEG-1 clip re-encoded to DVD-spec MPEG-2 VOB at a 6 Mbps constant bitrate produced a file around 230 MB. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — never shared or made public.
Can I go back to a regular video file later?
Yes. If you want a portable file instead of a disc image, our VOB to MP4 converter re-encodes the DVD stream to H.264 MP4 for phones and web playback, and the MPG to MP4 converter handles plain MPEG program streams the same way.
