VOB to MPG Converter

How to Convert VOB to MPG Online

1. Upload Your VOB File: Drag and drop or click "Add Files" to select VOB files from a ripped DVD's VIDEO_TS folder (VTS_01_1.VOB, VTS_01_2.VOB, etc.). Batch upload is supported — drop in every chapter at once and each becomes its own MPG file.
2. Pick Video Codec and Quality: Default is MPEG-2 (the native MPG codec, which lets the conversion act as a fast remux from the DVD source). Switch to MPEG-1 for legacy player compatibility, MPEG-4 / DivX / Xvid for smaller files, or H.264 / H.265 if your target player accepts them inside an MPG container. Choose a Quality Preset (Highest → Lowest), target a File Size Percentage with auto-scale, set an exact MB target, dial a Constant or Variable Bitrate, or fine-tune CRF (18 = visually lossless, 23 = default, 28 = smaller). Audio defaults to MP2 (the standard DVD/MPEG audio codec) — keep it for true DVD-style streams or swap to AC-3 to preserve Dolby Digital surround tracks.
3. Resize, Trim, or Keep Original: DVD source is 720×480 NTSC or 720×576 PAL — leave at Original to preserve native dimensions, pick a preset (4320p / 2160p / 1440p / 1080p / 720p / 576p / 480p / 360p), enter custom width × height, or scale by percentage. Use Trim with start time + duration in HH:MM:SS.sss format to drop FBI warnings, studio logos, or menu loops, or to split a multi-episode disc into separate MPGs.
4. Convert and Download: Click Convert. Files process in your browser session — no sign-up, no watermark, no 100 MB cap, no Google Drive / Dropbox round-trip required.

Why Convert VOB to MPG?

VOB (Video Object) is the DVD-Video container that wraps MPEG-2 video together with DVD-specific navigation packs, menu data, multi-angle headers, and subtitle (VobSub) streams inside the VIDEO_TS folder. The MPEG payload itself is standard, but VOB layers on overhead and timing references that confuse general-purpose media players, video editors, and Plex/Jellyfin scanners. MPG (MPEG program stream) is the same MPEG-1 / MPEG-2 video and audio in a clean, navigation-free container that virtually every player, editor, and DVD-authoring tool understands. Because both formats share the underlying codec, the conversion is usually a fast container-level rewrite with no quality loss.

• Cleaning up rips for editing in NLEs — DaVinci Resolve, Premiere Pro, Vegas Pro, and older editors often refuse VOB files or import them with broken timestamps. The same content as MPG imports cleanly with correct frame indexing.
• Fixing playback issues from damaged DVDs — VOB headers from scratched or partially-read discs frequently cause seek failures, audio desync, or premature end-of-file errors. Converting to MPG rebuilds proper program-stream headers and removes garbage between MPEG packets.
• Stitching DVD chapters into a single movie — A typical DVD splits a feature film across VTS_01_1.VOB through VTS_01_5.VOB at fixed 1 GB boundaries. Converting each to MPG and merging produces a single uninterrupted file you can play, archive, or upload as one unit.
• Re-authoring DVDs from a rip — DVD-authoring tools (DVDStyler, ConvertXtoDVD, TMPGEnc Authoring Works) expect MPG with MP2 or AC-3 audio as input, not raw VOB. Going VOB → MPG first gives the authoring tool a clean source.
• Archiving without re-encoding — When both source and target use MPEG-2, no quality is lost. The output MPG is the same picture as the disc, just with corrected headers and no DVD overhead — ideal for long-term archives where you want to keep the original master quality.
• Compatibility with broadcast and presentation hardware — Older projectors, broadcast playout decks, and DVD set-top boxes accept .mpg natively but choke on .vob outside a full VIDEO_TS structure.

VOB vs MPG — Format Comparison

Codec and Audio Choice Quick Guide

Frequently Asked Questions

Is VOB to MPG conversion lossless?

Yes, when the output codec stays at MPEG-2 (the default). The video and audio inside a DVD VOB are already MPEG-2 and MP2/AC-3, so the conversion rewrites the container only — fixing program-stream headers, dropping DVD navigation packs (NV_PCK), and producing a clean MPG. No re-encoding happens, so picture quality, frame count, and audio fidelity are byte-exact. If you switch the codec to MPEG-1, MPEG-4, DivX, or H.264, the file is re-encoded and quality depends on the CRF / bitrate you choose.

How do I convert all VOB files from a DVD's VIDEO_TS folder?

Open the VIDEO_TS folder on the ripped DVD and select every VTS_*.VOB file (VTS_01_1.VOB, VTS_01_2.VOB, VTS_01_3.VOB, etc.). Drop them all into the upload area and the converter processes each in parallel, producing one MPG per VOB. If you want a single combined movie, run the conversion first and then merge the MPG outputs with our Merge Video tool — merging works cleanly on MPG because each file already starts and ends on a proper program-stream boundary.

Why won't my media player or editor open the VOB directly?

VOB files outside a full VIDEO_TS folder structure carry DVD-specific navigation packs and timing references that general-purpose decoders don't expect. Players like Windows Media Player and editors like Premiere Pro / Resolve either refuse to open the file, fail to seek, lose audio sync after a chapter break, or stop early when they hit an NV_PCK. Converting to MPG strips that overhead and produces standard MPEG headers that every player and editor handles cleanly.

Can I keep the DVD's Dolby Digital 5.1 surround sound?

Yes — pick AC-3 as the audio codec. DVD audio is usually AC-3 (Dolby Digital 2.0 or 5.1), and AC-3 is one of the audio codecs the MPG program-stream container officially supports. Choosing AC-3 passes the DVD audio through bit-for-bit, preserving channel count and bitrate. Pick MP2 if you want the most universally-compatible MPG audio (every DVD-authoring tool and legacy player accepts MP2), at the cost of stereo only.

Will subtitles transfer from VOB to MPG?

Usually not. DVD subtitles are bitmap-based (VobSub), and the MPG program-stream container doesn't have a standard subtitle track for them — they're typically dropped during conversion. If subtitle preservation matters, convert to VOB to MKV instead — MKV supports VobSub subtitle tracks natively. Alternatively, burn the subtitles into the video pixels before conversion if you only need them visible on playback.

Should I convert VOB to MPG or MP4?

MPG if your target is DVD re-authoring (DVDStyler, ConvertXtoDVD), legacy hardware that only reads MPEG-2, or a fast lossless container fix. VOB to MP4 if you want smaller files, modern device support, or cloud archive — MP4 with H.264 typically lands around 20-30% of the source VOB size with no visible quality difference. There's no universally "better" pick; it depends entirely on what plays the file on the other end.

Can I split a long DVD movie into smaller MPG files?

Yes. Use the Trim option, which takes a start time and a duration in HH:MM:SS.sss format (or plain seconds, e.g. 12.5). To split a 2-hour movie into two MPGs, run the conversion twice — first with start 00:00:00 / duration 01:00:00, then with start 01:00:00 / duration 01:00:00. The same approach splits multi-episode TV-show discs into individual episodes. Each output is a standalone MPG file that plays on any standard MPEG player.

What's the practical file size limit?

There's no fixed cap — conversion runs in your browser, so the limit is your device's RAM and upload time. A full dual-layer DVD (around 8 GB total across all VOBs) works on a desktop with 8 GB+ RAM. Multi-VOB rips and full VIDEO_TS folder uploads work without the 100 MB / 25-file caps that most online competitors enforce. Batch jobs have no quantity limit either.

Can I convert MPG back to VOB to author a DVD?

Yes — use our MPG to VOB tool, or convert from MPEG-2 directly with MPEG-2 to MP4 reversed. For a more direct DVD-authoring path, most authoring software (DVDStyler, ConvertXtoDVD, TMPGEnc) accepts MPG with MP2 or AC-3 audio as the source and handles the VIDEO_TS / VOB output itself, so you typically don't need a separate MPG → VOB conversion step.
