As most itunes users know, iTunes not only allows users to purchase classic films or popular videos from its store but also provide rental service for the users. People are more likely to rent a movie than buy one, that means cost less.
However, low cost also has its drawbacks. Once you’ve started to watch the movie, you have 24 hours to finish watching the movie (even if you start watching before the download is complete). You can watch the movie as many times as you want within this 24-hour period. The rented movie will expire when either the 30 day or 24-hour limit is reached. Once the rental expires, the movie is automatically deleted. You must re-rent and download the movie to view it after your rented movie has expired.
So in order to keep iTunes movie rentals for long time with MP4 players while not online, the rented files needed to be converted with an appropriate program.
1. Download a converter program like M4V Converter Plus for Win. Install the program by double-clicking on the installation file after download. Finish the installation, click the icon and launch it.
2. Click the Add Movies in top left corner, then you will see the pop up windows which will show you all the iTunes purchases and rentals. Find the file you want to convert and click OK button.
3. The added movie rentals will show up on the main window. And then set the output as you need. Here we choose Same as source for MP4 from the output profile list.
4. Click Convert button to start the iTunes movie rentals to MP4 conversion.
