Convert M4V to an SRT subtitle file

M4V is the video format iTunes and Apple TV use for purchased and rented content. It is structurally similar to MP4 but may carry Apple FairPlay DRM on purchased files. SnailText handles unprotected M4V files, which includes personal recordings, exports from iMovie, and any M4V you created yourself.

You get a separate .srt file ready to attach to the video in any player or editor. M4V uses a one-time codec pack the app downloads for you.

How to convert M4V to SRT

  1. Open the Transcribe files screen in SnailText.
  2. Add your M4V video (or a folder of videos).
  3. Choose SRT as the output before you run it.
  4. Run it. The .srt file is saved next to your video.

M4V to SRT free, without uploading the video

Online subtitle generators upload your video to a server. SnailText does it locally: the video stays on your computer, there is no length limit, and no watermark. M4V uses a one-time codec pack the app downloads for you, then runs offline.

SnailText works on unprotected M4V files. DRM-protected iTunes purchases cannot be read by any local tool. If you need SRT from a file you created or exported from iMovie, it will work.

If you only want the plain transcript of an M4V rather than a subtitle file, the M4V to text page covers that.

M4V to SRT FAQ

How do I generate subtitles for an M4V file?
Install SnailText, open Transcribe files, add your M4V, choose SRT as the output, and run it. It generates the SRT locally, nothing is uploaded. M4V uses a one-time codec pack the app downloads for you. DRM-protected iTunes purchases cannot be processed by any local tool.
Can SnailText read an M4V from iMovie?
Yes. iMovie exports unprotected M4V files that SnailText can read without issue. Add the file, choose SRT as the output, and run it.
What is the difference between M4V to SRT and M4V to text?
M4V to SRT produces a timed subtitle file (.srt) with start and end times per phrase. M4V to text produces a plain transcript with no timestamps. SnailText does both, you just pick the output before the run.
Does SnailText burn the subtitles into the video when I use M4V to SRT?
No. SnailText writes a separate SRT and VTT file and does not hardcode captions into the video. That keeps the subtitles editable and lets you attach them in any player or editor. If you want them burned in, overlay the file in a video editor afterward.
