Free online M2V to VOB converter

DVD authoring software, set-top DVD players, and some legacy video editors expect MPEG-2 program streams in VOB containers rather than standalone M2V video. The conversion is also useful when combining an M2V video stream with audio and DVD navigation data for a video disc.

What the M2V format is

M2V is an elementary MPEG-2 video stream: it contains video only, with no audio, subtitles, menus, chapters, or DVD navigation data. It commonly comes from DVD demultiplexing tools, MPEG-2 encoders, broadcast workflows, and authoring applications that export separate audio and video streams. Files from tools such as FFmpeg, TMPGEnc, Adobe Premiere, and DVD extraction software may use the .m2v extension.

What the VOB format is

VOB is a DVD-Video container based on MPEG program streams. A VOB can contain MPEG-2 video, MPEG-1 or MPEG-2 audio, AC-3 audio, subtitles, and DVD navigation packets. DVD movie data is stored in files such as VTS_01_1.VOB inside a VIDEO_TS folder, normally alongside matching .IFO and .BUP files.

VOB is appropriate when the destination is DVD authoring, a legacy DVD player, or software that specifically requires DVD-Video program-stream data. A VOB file by itself is not a complete authored DVD and normally does not contain menus, titles, or usable chapter navigation.

How to convert M2V to VOB

Using the online converter

You can convert the file on 101convert.com for free without installing software:

1. Open the site’s video converter and select the M2V-to-VOB conversion.
2. Upload the .m2v file.
3. Choose VOB as the output format and start the conversion.
4. Download the resulting .vob file when processing finishes.

Because M2V contains no audio, the resulting VOB will also have no audio unless the converter accepts a separate audio track or the source already includes additional stream data.

Using FFmpeg for a standalone VOB

FFmpeg can remux a compatible M2V stream without re-encoding:

ffmpeg -i input.m2v -map 0:v:0 -c:v copy -f vob output.vob

This preserves the MPEG-2 video and therefore avoids another generation of quality loss. If the M2V does not meet DVD-Video requirements, encode it to a DVD-compatible profile instead:

ffmpeg -i input.m2v -target pal-dvd output.vob

For an NTSC project, use -target ntsc-dvd. These presets may change resolution, frame rate, bitrate, and encoding structure, so inspect the source standard before choosing one.

Creating a playable DVD

To produce a disc or a complete VIDEO_TS folder, use DVDStyler, DeVeDe, or another DVD authoring program rather than only changing the extension. Import the M2V and its separate audio file, set the television standard, create menus or chapters if needed, and select Build, Compile, or Burn. The authoring program creates VOB, IFO, and BUP files and arranges them according to the DVD-Video specification.

Quality, compatibility, and limitations

• Renaming .m2v to .vob does not convert the format; the file must be placed in a VOB-compatible program stream.
• Copying the video stream with -c:v copy is lossless, but it works reliably only when the MPEG-2 stream is already DVD-compliant.
• DVD-Video normally uses MPEG-2 video at 720×480 or 720×576, with permitted lower-resolution modes depending on the television standard. PAL and NTSC frame rates are not interchangeable without conversion.
• A standalone VOB may play in VLC and some media players but fail in a hardware DVD player because it lacks the accompanying IFO navigation files and DVD directory structure.
• Since M2V has no audio stream, audio must be supplied separately for a normal DVD movie. Authoring software multiplexes it into the VOB and synchronizes it with the video.
