What changes when you convert MOV to M4V?
MOV and M4V are containers, while the video and audio codecs live inside them. Compatible streams may be copied; otherwise they are re-encoded for the selected M4V settings.
- For the widest playback support, check that the selected video and audio codecs are accepted by the device or service that will receive the M4V file.
- Add multiple videos and adjust the available video and audio codec settings before processing.
- Open the finished M4V file and check fine details, layout and compatibility in the app where you plan to use it.
Source formatWhat is a MOV file?
MOV is Apple’s QuickTime video format, the default for footage recorded on iPhone and Mac. It offers excellent quality but larger files, and plays best in the Apple ecosystem - converting to MP4 makes it universal.
How to open a MOV file
MOV opens natively in QuickTime on Mac and iOS. On Windows or Android, use VLC or convert it to MP4 for full compatibility.
Output formatWhat is a M4V file?
M4V is Apple’s take on the MP4 video container, used by iTunes for films and TV shows. It is almost identical to MP4, but store-bought M4V files can carry DRM copy protection; renaming to .mp4 often works, otherwise a real conversion is needed.
How to open a M4V file
M4V plays in QuickTime, iTunes/Apple TV and VLC; for wider support convert it to MP4.
