If you like to download free podcast videos in iTunes, sometimes you may get videos in M4V format. These M4V videos are unprotected and can be easily converted to MP4 or other video formats with some free M4V converters. However, all M4V videos including the free M4V TV shows you purchased or rented from iTunes Store, are encrypted. If you need to convert encrypted M4V to MP4, a professional decryption tool will be needed.

Plain and Encrypted M4V Videos

M4V format

Although iTunes is overstaffed, we must acknowledge the fact that iTunes Podcasts (iTunes U included) do provide a lot of funny and useful videos and audio files for entertainment and study. If you have subscribed and download some podcasts, you may find downloaded podcast videos could be in MP4, MOV or M4V file extensions. All of the 3 video formats can be watched on iPhone and iPad directly.

The M4V videos from iTunes podcasts are unprotected and there is no need to authorize your devices with Apple ID. Some Android devices like Samsung Galaxy S8 can also play unprotected M4V videos directly without conversion. However, most Android devices including Huawei Mate 10 can't recognize M4V file extension. If you want to watch those M4V videos on those Android devices, you can use a video converter to convert M4V to MP4 first. There are some free M4V converters and we will recommend later.

Additional Tips

The M4V file format is a video container format developed by Apple and is very similar to the MP4 format. The primary difference is that M4V files may optionally be encrypted. Plain M4V videos can be played with VLC Media Player, KMPlayer, Media Player Classic, Realplayer, etc. Some video players can recognize and play M4V files if the file extension is changed from ".m4v" to ".mp4".
