VOB to M4V Conversion FAQ
What does the VOB to M4V converter do?
+
VOB is a legacy container, often poorly supported on modern devices. Converting to M4V rewraps the video with a current codec (H.264 / H.265 / VP9) for broad browser, phone, and TV compatibility.
Will resolution and frame rate be preserved in the M4V?
+
Yes. VOB → M4V keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
My VOB footage shows comb lines on movement — will that carry into the M4V?
+
Yes. VOB content is often interlaced, because the format comes from the broadcast and DVD era, and this converter has no deinterlace option, so the combing carries into the M4V. If it matters, deinterlace the VOB first in a desktop tool such as HandBrake or ffmpeg (the yadif filter). VOB is the Video Object container found in the VIDEO_TS folder of every DVD — an MPEG-2 program stream with DVD-specific navigation data added.
My VOB recordings are split into numbered parts — does M4V have the same limit?
+
No, and that is one of the better reasons to move. The VOB container has a practical single-file ceiling that long or high-bitrate recordings run straight into, which is exactly why old captures arrive as part1, part2, part3. M4V has no equivalent limit, so the pieces can be rejoined into one continuous file. VOB is split across files, may be CSS-encrypted, and carries navigation packets that confuse general-purpose players.
Will the M4V I get back be locked to a store or an account?
+
No, and the extension is what causes the confusion. M4V names a video file with the same internal structure as an ordinary MP4; the ones sold through a store are additionally wrapped in the seller's protection, and that wrapping is a property of the purchase rather than of the format. A file converted here has none of it — a plain, unprotected video that happens to carry that extension, playable wherever the extension is recognised and convertible onward as many times as you like. M4V is Apple’s variant of MP4, used by iTunes and the Apple TV app for films and TV episodes.
Why does my VOB file fail to convert to M4V?
+
Almost always DRM. Some VOB files are encrypted at the bitstream level by the store or software that issued them, and an encrypted stream cannot be decoded by us or by anything else without the licence key. Files you recorded, exported or downloaded unprotected convert normally; a licensed purchase will not, and no converter can honestly promise otherwise.
Is it worth converting old VOB recordings to M4V at all?
+
For anything you intend to keep, yes. VOB belongs to an earlier generation of video tooling and the software that reads it is steadily disappearing from phones, browsers and operating systems. Moving the footage to M4V now, while a clean decoder still exists, is the difference between an archive you can open in ten years and one you cannot. M4V keeps chapter markers, artwork and subtitle tracks in the shape the Apple TV app expects, which plain MP4 often loses.
Is there a file-size limit when converting VOB to M4V?
+
Free conversions have a size limit per file, set by the type of file, and the page tells you when a file is over it. A paid plan removes that limit, so much larger files can be converted.
Can I batch-convert several VOB files to M4V at once?
+
Several files in one job need a paid plan. Free use is one file per conversion, one conversion an hour. On a paid plan you can add several files to one job, then download each result on its own or all of them in one ZIP.
What happens to my VOB files after the conversion?
+
Uploaded files are processed on our own conversion servers, nobody looks at them, and they are not shared. The upload and the converted file are both deleted automatically about 24 hours after the conversion, which leaves time to download the result. See /privacy/ for the full policy.
Will my M4V play on phones, tablets, and TVs?
+
Yes — M4V uses modern codecs that play natively on iOS, Android, Smart TVs, game consoles, and every modern browser.
Do I need to install software to convert VOB to M4V?
+
No. The converter runs entirely in your browser plus our cloud — no plugin, no install, no admin rights. It works on Windows, macOS, Linux, ChromeOS, iOS, and Android.
