Understanding M4V files

What is a M4V file?

Apple's video format with optional DRM protection

M4V files were developed by Apple and are very similar to the MP4 file format. However, a file with the M4V file extension is called an iTunes Video file (MPEG-4 video file). Some of the M4V files that you’ll encounter may have DRM copyright protection to prevent unauthorized distribution and copying of the video. These files are typically downloaded from iTunes. You can try uploading them to Sonix and we’ll only be able to transcribe M4V files that do not have DRM protection.
