MP4 to VOB Converter

How to Convert MP4 to VOB Online

1. Upload Your MP4 File: Drag and drop or click "Add Files" to select MP4 / M4V clips — phone recordings, GoPro footage, screen captures, downloaded videos, or edited timeline exports. Batch upload is supported, drop in an entire folder of episodes ready to be authored to a DVD.
2. Pick MPEG-2 Codec and DVD Audio: VOB is locked to MPEG-2 video by DVD-Video spec — that's the default here. Audio defaults to AC-3 (Dolby Digital, what commercial DVDs ship with) and MP2 is the alternative for stereo-only universal-player compatibility. Pick a Quality Preset (Highest → Lowest), dial Constant Bitrate at the DVD-friendly 4-9 Mbps range, set Variable Bitrate for size-efficient archival, target a File Size Percentage with auto-scale, or enter an exact MB target. CRF / qscale (1-31, lower is sharper) gives fine-grained control when you're authoring a specific disc capacity.
3. Resize to DVD Resolution or Trim (Optional): DVD-Video is locked to 720×480 NTSC or 720×576 PAL — pick the 480p preset for NTSC source (USA, Japan), 576p for PAL (Europe, Australia), enter custom width × height, or scale by percentage. Use Trim with start time + duration in HH:MM:SS.sss format to drop intros, ad breaks, or split a long MP4 into chapter-sized segments before authoring.
4. Convert and Download: Click Convert. Files are uploaded over an encrypted connection, processed on our servers, and deleted automatically after a few hours — no sign-up, no watermark, never shared.

Why Convert MP4 to VOB?

MP4 with H.264 plays on every phone, browser, smart TV, and console made since 2010 — but it doesn't play on a standard DVD player. The DVD-Video specification (1996) mandates MPEG-2 video at 720×480 NTSC or 720×576 PAL, with AC-3 / MP2 / LPCM audio, all wrapped in VOB containers inside a VIDEO_TS folder. Converting MP4 → VOB is the bridge from "modern phone recording" to "playable on grandma's living-room DVD player or a car-DVD-screen road trip." Below are the most common reasons people convert MP4 to VOB:

• Burning home videos to DVD-Video discs — Wedding, graduation, baby, and travel videos still get gifted as physical DVDs, especially for older family members without a smart TV. DVD authoring software (DVDStyler, ImgBurn, Nero, TMPGEnc Authoring Works) requires elementary MPEG-2 streams at ≤9.8 Mbps, so MP4 H.264 has to be transcoded first.
• Playing MP4 on older DVD players and car DVD screens — Many 2000s-era DVD players, in-car rear-seat screens, and hospitality-room players reject MP4 over USB but happily play burned VOB DVDs. Re-encoding once and burning solves a whole-room compatibility problem.
• Memorial and legacy DVD sets — Funeral homes, photo studios, and family historians still deliver memorial slideshows as DVD-Video so older relatives without streaming accounts can watch on any TV.
• Corporate training and conference DVDs — Industries with restricted networks (medical, legal, military, education) often standardize on physical DVD distribution. Speaker recordings exported as MP4 must be transcoded to VOB before authoring.
• Re-authoring after editing — Editors who rip a DVD to MP4 with our VOB to MP4 tool, edit in Premiere or DaVinci Resolve, and need to put the result back on a playable disc round-trip through MP4 to VOB.
• Wedding videographers and school yearbook DVDs — Final-deliverable DVDs are still requested for archival shelves alongside the streaming link, especially for clients who want a permanent off-cloud copy.
• Importing MP4 into legacy DVD authoring chains — TMPGEnc, AVS Video Converter, and the AviSynth + DVDStyler workflow all expect MPEG-2 elementary streams. MP4 H.264 is rejected at ingest.

Frequently Asked Questions

Will the VOB file be larger than the MP4 source?

Yes, almost always. MP4 H.264 is roughly 2-3× more efficient than DVD-spec MPEG-2 at the same picture quality, so a 700 MB MP4 typically grows to 1.5-2 GB as VOB at 6-8 Mbps. A 1.5 GB MP4 movie usually becomes 4-5 GB on disc. The conversion tradeoff is compatibility, not compression: VOB is what DVD players require, even though modern codecs are more efficient. Plan for the destination disc capacity (4.7 GB single-layer DVD-5 or 8.5 GB dual-layer DVD-9) when picking the bitrate.

Should I pick NTSC (480p) or PAL (576p) resolution?

NTSC (720×480 at 29.97 fps) for DVD players sold in the USA, Canada, Japan, and most of Latin America. PAL (720×576 at 25 fps) for the UK, Europe, Australia, India, and most of Africa. Mismatched standards either won't play or will play with frame-rate stutter. If you don't know the destination region, NTSC is the safer default for the Americas and PAL for everywhere else. Modern multi-region DVD players accept both; legacy hardware often doesn't.

Will the output work with DVD authoring software?

Yes. The default output is DVD-Video compliant: MPEG-2 video at 4-9 Mbps, AC-3 or MP2 audio, 720×480 NTSC or 720×576 PAL resolution. Drop the.vob files (or use the.mpg /.m2v sibling tools if your authoring chain prefers those) into DVDStyler, ImgBurn, Nero, or TMPGEnc Authoring Works and they ingest without a re-encode pass. For elementary stream workflows, see our MP4 to MPEG-2 tool.

Can I keep my MP4's original frame rate and audio?

DVD players expect 29.97 fps for NTSC or 25 fps for PAL and can stutter or refuse off-spec rates — but nothing here normalises the frame rate for you, so the source rate is carried straight through. Set the Framerate control yourself to match the standard you are authoring for. Source audio (AAC, MP3, Opus) is re-encoded to AC-3 by default for surround compatibility, or MP2 for stereo-only DVDs. If your MP4 has 5.1 surround AAC, pick AC-3 to preserve the multi-channel layout; pick MP2 for plain stereo content where universal player compatibility matters more than audio codec choice.

Can I burn the.vob file directly to a DVD?

Not as a single file — DVD players read the VIDEO_TS folder structure with VTS_01_1.VOB, VTS_01_2.VOB, IFO, and BUP files all together, not a loose.vob on disc. After this conversion, take the.vob output into a DVD authoring tool (DVDStyler is free, ImgBurn handles the burn) to build the VIDEO_TS folder with menus and chapter markers, then burn that folder structure to a DVD-R. The conversion produces the spec-compliant video; authoring builds the disc.

Can I trim or split the MP4 while converting?

Yes. The Trim option takes a start time and a duration, both accepting seconds (12.5) or HH:MM:SS.sss format (00:01:30.500). Useful for splitting a 3-hour wedding MP4 into a ceremony disc plus a reception disc, dropping unwanted intros, or pulling individual chapter segments before authoring. Run the conversion multiple times with different trim ranges to produce a multi-disc set.

What's the practical file size limit?

There is no fixed cap — conversion runs on our servers, so the limit is upload size and connection speed and the upload time. A 2-hour 1080p MP4 (typically 2-4 GB) converts fine on a desktop with 8 GB+ RAM. Multi-GB camcorder MP4s and full-feature movie files work without the 100 MB / 1 GB free-tier caps that competitors like Convertio and CloudConvert enforce.

Can I convert VOB back to MP4 later?

Yes — see VOB to MP4 for the reverse direction (useful when ripping the DVD you just authored to a phone-friendly file). For other DVD-related targets, see MP4 to MPEG-2 for elementary-stream authoring chains and MP4 to AVI for older PC playback workflows.
