VOB to M2V Converter

How to Convert VOB to M2V Online

1. Upload Your VOB File: Drag and drop or click "+ Add Files" to add one or more VOB files from a DVD's VIDEO_TS folder. Batch upload is supported, and each file is processed independently.
2. Pick Quality Preset and Video Codec: Default is Very High with MPEG-2, the canonical codec for M2V elementary streams. Use the Quality Preset dropdown (Highest, Very High, High, Medium, Low, Very Low, Lowest) for one-click control, switch to Constant Bitrate or Variable Bitrate for a target Mbps, or pick Constant Quality / Constraint Quality to tune the qscale value directly. The audio tracks inside the VOB are dropped because M2V is a video-only elementary stream.
3. Resolution and Trim (Optional): Keep the original DVD resolution (720x480 NTSC or 720x576 PAL), pick a preset like 1080p or 480p, scale by percentage, or set a custom Width x Height. Use the Trim section to switch from "Unchanged" to a Time Range and export only the chapter or segment you need.
4. Convert and Download: Click "Convert". Files process server-side and download directly — no watermark, no sign-up, no email required.

Why Convert VOB to M2V?

VOB (Video Object) is the multiplexed container DVD-Video discs have used since 1996, packing one MPEG-1 or MPEG-2 video stream with up to 8 audio tracks (AC-3, DTS, MPEG-1 Layer II, or LPCM) and up to 32 subpicture streams, plus navigation data. M2V is the opposite: a raw MPEG-2 video elementary stream with no container, no audio, and no subtitles. Demuxing a VOB to M2V isolates the video so it can be re-authored, edited, or re-encoded without dragging the DVD's audio and menu structure along.

• DVD re-authoring — TMPGEnc Authoring Works, DVD Architect, and DVDStyler all accept M2V + separate AC-3/WAV inputs. Splitting VOB into M2V plus an audio file is the standard prep step before building a new DVD or Blu-ray project.
• Broadcast and archival workflows — SMPTE-style mastering pipelines keep video and audio as separate essences. M2V is the MPEG-2 video essence that pairs with a WAV or AC-3 audio file in the final mux.
• Editing the video without touching the audio — NLEs like Adobe Premiere, DaVinci Resolve, and Vegas Pro can import M2V cleanly; the audio is handled as a separate track, which avoids accidental sync drift during cuts.
• Re-encoding for a new bitrate or resolution — Going VOB to M2V first gives you a clean MPEG-2 source to feed into a second pass (e.g., M2V to MP4 with H.264) without the VOB container confusing the encoder about which audio stream to pick.
• Salvaging individual chapters — A DVD's VOB files often span multiple chapters. Trim during conversion to export just the video you want, then mux it back with the desired audio later.
• Stripping out region locks, menus, and unwanted angles — VOB carries DVD navigation; M2V doesn't. Extracting M2V leaves a portable raw video stream with no playback-controller baggage.

Quality Preset Quick Guide for M2V Output

DVD-Video tops out at 9.8 Mbps for video per the spec, which is why Very High sits around 6-8 Mbps — that is the practical sweet spot the original VOB likely already uses.

Frequently Asked Questions

Where does the VOB's audio go when I convert to M2V?

It's discarded. M2V is a video-only elementary stream by definition — it has no container slot for audio. If you need the audio, run the VOB through a separate conversion to AC-3, WAV, or VOB to MP3 and keep both files side by side. DVD authoring tools then mux the M2V video and the separate audio at the final step.

Will this re-encode the video or just rewrap it?

It re-encodes. The converter decodes the VOB's MPEG-2 video and re-encodes to MPEG-2 inside an M2V elementary stream with whatever bitrate or quality you choose. If you only want a lossless demux of the existing MPEG-2 stream, the result will be near-identical at the Highest preset, but it is still a re-encode rather than a stream copy.

What's the difference between M2V and MPG?

MPG (MPEG Program Stream) is a container that holds video plus audio multiplexed together. M2V is just the video elementary stream — no audio, no muxing. Think of MPG as the finished sandwich and M2V as one of the slices. For an MPG-style output instead, see VOB to MPEG2 or VOB to MPEG.

What resolution should I pick for DVD-compliant M2V?

For NTSC DVDs use 720x480 at 29.97 fps; for PAL DVDs use 720x576 at 25 fps. DVD-Video also permits 704x480/576 and 352x480/576. If you're authoring back to DVD, keep the source resolution — upscaling to 1080p inside an M2V breaks DVD spec and will be rejected by most authoring tools.

My VOB has multiple chapters and angles. Which one ends up in the M2V?

The first video stream in the VOB. DVD authoring uses interleaved blocks where multiple angles or seamless branches share a single VOB; the converter follows the default angle and the linear program stream. If you need a specific chapter only, use the Trim section to set the start time and duration before converting.

Can I open M2V files in VLC or Windows Media Player?

VLC plays M2V directly because it understands raw MPEG-2 elementary streams. Windows Media Player and QuickTime typically refuse to open M2V without a container — they expect a muxed format like MPG or MP4. If you want a file that "just plays" everywhere, convert to M2V to MP4 afterwards.

What's the maximum file size I can upload?

There's no hard cap for batch use, but a single VOB on a DVD is capped at roughly 1 GB by the UDF file system the disc uses. If your source spans multiple VOB_01_1.VOB, VOB_01_2.VOB, etc., upload them together and convert each — they're chapters of the same title split at the 1 GB boundary, not separate movies.

Why would I pick M2V over a more modern format like MP4?

You wouldn't, unless you're working with DVD-era authoring tools or a broadcast workflow that expects separate video and audio essences. M2V exists for that specific niche. For everyday playback, sharing, or editing, MP4 with H.264 is a better target — try VOB to MP4 instead.
