M4V to VOB Converter

M4V to VOB Converter

M4V is Apple's MP4 variant — an H.264 video stream with AAC audio, used by iTunes, Apple TV, and QuickTime. VOB (Video Object) is the container DVD-Video uses to hold MPEG-2 video and AC-3 audio inside a disc's VIDEO_TS folder. Converting M4V to VOB re-encodes your footage into the MPEG-2 format a standalone DVD player can read, which is the starting point when you want to author a playable DVD from Apple-ecosystem source. If you only want the clip to play somewhere modern, keep the efficient H.264 and use M4V to MP4 instead — VOB is for actual DVD authoring.

M4V Format at a Glance

VOB Format at a Glance

VOB is a rigid standard-definition format, so an HD or 4K M4V is downscaled to 720×480 or 720×576 during conversion. Because MPEG-2 is far older and less efficient than the H.264 in your M4V, matching the source's look needs a much higher bitrate, and the resulting VOB is usually larger than the M4V it came from. This is a compatibility conversion for DVD playback, not a way to shrink a file or improve quality — re-encoding H.264 to MPEG-2 is lossy-to-lossy and never regains detail.

How to Convert M4V to VOB

1. Upload Your M4V File: Drag and drop your .m4v onto the page, or click "+ Add Files" to browse. You can queue several clips and convert them with the same settings.
2. Set the Quality Preset: Open Advanced Options and leave Preset on "Very High (Recommended)" so the MPEG-2 encoder spends enough bitrate to keep the downscaled-to-SD picture clean; 5-8 Mbps is a clean sweet spot for standard definition.
3. Pick a Resolution and DVD Audio: Under Video resolution, use Preset Resolutions to lock to 720×480 (NTSC) or 720×576 (PAL). The video codec is MPEG-2 and audio defaults to MP2, switchable to AC-3 for Dolby Digital. Use Trim's Time Range if you only need part of the clip.
4. Convert and Download: Click Convert and download the .vob. No sign-up, no watermark.

Frequently Asked Questions

Can I convert a DRM-protected iTunes M4V to VOB?

No. Movies and TV shows bought or rented from the iTunes Store are often wrapped in Apple's FairPlay copy protection, which restricts playback to devices authorized with the purchasing Apple account. A FairPlay-protected M4V cannot be decoded by any converter, so the conversion fails. Only DRM-free M4V files — your own screen recordings, exports, camera footage, or downloads that were never encrypted — can be converted to VOB.

Why is my VOB file larger than the original M4V?

DVD-Video uses MPEG-2, which is far less efficient than the H.264 codec inside your M4V. Even after downscaling to standard definition, MPEG-2 needs a high bitrate to look clean, so the VOB often ends up bigger than the source. That is expected — this conversion targets DVD-player compatibility, not file-size savings. If you want a smaller, modern file for streaming or sharing instead, keep the footage as MP4 with M4V to MP4 or use the Video Compressor.

Will my HD or 4K M4V stay high-definition in the VOB?

No. DVD-Video is a standard-definition format limited to 720×480 (NTSC) or 720×576 (PAL), so any 1080p or 4K M4V is downscaled to fit. The picture will look fine on a TV through a DVD player, but it is no longer HD, and downscaling cannot be reversed afterward. If you need to keep full resolution, convert to a modern container instead of VOB.

Is a VOB file the same as a finished DVD?

Not quite. A VOB holds the video and audio, but a complete DVD-Video disc also needs the IFO (navigation) and BUP (backup) files plus a VIDEO_TS folder structure that DVD-authoring software builds. Use this converter to produce the MPEG-2 VOB, then import it into a DVD-authoring or burning tool (DVDStyler is free; ImgBurn handles the burn) to assemble menus and write a playable disc.

Which audio codec should I choose for a DVD?

MP2 (MPEG Audio Layer II) is the default here and plays on every DVD player. AC-3 (Dolby Digital) is the other widely compatible choice and is preferred for 5.1 surround on NTSC discs. DVD-Video also permits Linear PCM and DTS, but AAC — the codec your M4V carries — is not allowed in DVD-Video, which is why the audio is always re-encoded rather than copied.

NTSC or PAL — which resolution do I pick?

Match the region your DVD player expects. NTSC (720×480 at 29.97 fps) is standard in North America and Japan; PAL (720×576 at 25 fps) is standard across most of Europe, Africa, and Asia. Many modern players read both, but choosing the wrong standard can cause playback or frame-rate issues on older hardware.

Can I play a VOB without burning it to a disc?

Yes. Players such as VLC, PotPlayer, and MPV open .vob files directly, and VLC can also play a whole VIDEO_TS folder. In our testing, a 720×480 NTSC VOB exported at the Very High preset played back cleanly in VLC on both Windows and macOS without any disc step. If you want a file that plays on phones and most apps too, convert to MP4 instead, or rip an existing disc with VOB to MP4.

How are my files handled, and how long are they kept?

Your M4V is uploaded over an encrypted connection, processed on our servers, and deleted automatically a few hours after the conversion — no sign-up, no watermark, never shared or made public.
