M4V to MPEG Conversion FAQ
Will resolution and frame rate be preserved in the MPEG?
+
Yes. M4V → MPEG keeps resolution, frame rate, and aspect ratio unchanged by default. To change them, use the Resize or Speed tool on the result.
Is the M4V to MPEG conversion reversible?
+
You can convert the MPEG back to M4V on this site. If either format involved is lossy, the round-trip is not bit-perfect even though it is visually or audibly close.
What happens to the subtitle tracks in my M4V file?
+
They are dropped. MPEG has no soft-subtitle stream to hold them, and the converter neither burns them into the picture nor exports them as a separate file. If you need them, extract the subtitles to an .srt file with a desktop tool such as ffmpeg or MKVToolNix before converting, and load that file alongside the MPEG in your player. MPEG-2 needs roughly four to six times the bitrate of H.264 for the same picture, and its content is frequently interlaced, which looks combed on modern displays.
Why does my M4V file fail to convert to MPEG?
+
Almost always DRM. Some M4V 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. DRM-protected M4V purchases cannot be converted by anything; only unprotected M4V files are convertible, and non-Apple players often need the extension renamed.
Why would I convert M4V to an older format like MPEG?
+
Because a lot of hardware never learned anything newer and never will. DVD players, in-car head units, camcorder playback modes, industrial displays and plenty of broadcast ingest equipment accept MPEG and nothing else. The conversion is a deliberate step down in efficiency, bought in exchange for working on a device that has no other option. MPEG program streams are decoded by literally every DVD player, set-top box and broadcast chain ever built, and they tolerate bit errors gracefully.
Is there a file-size limit when converting M4V to MPEG?
+
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 M4V files to MPEG 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 M4V 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 MPEG play on phones, tablets, and TVs?
+
MPEG plays in most desktop players but is sometimes unsupported on mobile and TV. For broadest reach, consider MP4 instead.
Do I need to install software to convert M4V to MPEG?
+
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.
Do I need an account to convert M4V to MPEG?
+
Yes. One conversion an hour is free, with no account needed, for a file within the free size limit. A paid plan removes the hourly limit and the size limit, and lets you add several files to one job.
Is there an API for M4V to MPEG conversion?
+
Yes. Every conversion this site offers is also exposed via a JSON API — see /api/ for endpoints, authentication, and rate limits. M4V to MPEG is one of the supported pairs.
