MPG to VOB Converter

MPG to VOB Converter

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 strict bitrate, resolution, and audio rules baked in. Converting MPG to VOB re-encodes your footage to the DVD-Video flavor of MPEG-2 — video capped at 9.8 Mbit/s, sized to 720×480 (NTSC) or 720×576 (PAL), with DVD-legal audio — so DVD authoring software will accept it. Because the DVD spec constrains bitrate, resolution, and GOP structure, this is a genuine re-encode even when the source is already MPEG-2, not a simple container swap. 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

1. 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.
2. 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 — keep it at or below the DVD-legal 9.8 Mbit/s ceiling, typically 4–8 Mbps — a Variable Bitrate for size efficiency, or an exact file size in MB.
3. Set Resolution or Trim (Optional): Enter a custom Width × Height — 720 × 480 for the NTSC frame or 720 × 576 for the PAL frame DVD players expect. The Preset Resolutions list sets height alone and lets the width follow your source's aspect ratio, so "480p" on a widescreen capture gives 854 × 480 rather than a DVD raster. Use Trim with a start time and duration to drop intros or split a long capture into chapter-sized pieces before authoring.
4. 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 DVDStyler, DVD Flick, or ImgBurn) to build the full VIDEO_TS structure, then burn it.

Does converting MPG to VOB improve quality?

No conversion can add detail the source never captured. Even when your MPG is already MPEG-2, xconvert re-encodes it to meet the DVD-Video rules — the 9.8 Mbit/s video ceiling, the 720×480 or 720×576 frame, and DVD's GOP structure — so the step is a genuine re-encode rather than a copy. If the source is MPEG-1, moving up to DVD-spec MPEG-2 is doubly worthwhile, since MPEG-1 video on a DVD is itself limited to 1.856 Mbit/s. Keep the bitrate generous to avoid stacking fresh compression artifacts on the original.

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.

What bitrate should I choose to fit my footage on a DVD?

A single-layer DVD holds about 4.7 GB, and the DVD-Video spec caps video at 9.8 Mbit/s. At that maximum you fit roughly one hour of footage; dropping to around 5 Mbps stretches a single disc to about two hours with a modest quality trade-off. As a rule of thumb, divide the disc's usable bits by your runtime: for a two-hour capture, a Constant Bitrate near 4.5–5 Mbps keeps everything on one disc while leaving headroom for the audio track.

Why might my VOB get split into multiple files?

DVD VOB files are capped near 1 GB (1 GiB) 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.
