.m4v — MPEG-4 Video
An MP4-like video container commonly associated with Apple media libraries and video downloads.
About this format
M4V is closely related to MP4 and is often used by Apple software for video files. Many M4V files can be renamed or remuxed for MP4 workflows, but DRM or codec choices can still limit playback.
Use M4V when working inside Apple media ecosystems. Use MP4 for general sharing.
