What changes when you convert AVI to M4V?
AVI 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 AVI file?
AVI is a classic Microsoft video format from the 1990s. It offers broad compatibility and good quality but large, inefficient files, so it is mostly replaced by MP4 today - though it is still common in older archives.
How to open a AVI file
AVI opens in Windows Media Player, VLC and most desktop players; for phones and browsers, converting to MP4 is the reliable choice.
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.
