MP4 is an HTML5 compatible video format that is supported by Chrome, Safari, Microsoft Edge, iPhone, iPad, Android and Flash.
In this tutorial, we use the freeware Handbrake https://handbrake.fr/ to convert MP4 videos. Handbrake https://handbrake.fr/ is an open source, GPL-licensed application for encoding MP4 video. It works on Windows, Linux and Mac.
Step 1 – Download Handbrake
Go here https://handbrake.fr/ and click the red button to download Handbrake. You will be prompted to save the program file. Save it somewhere easy to find, we suggest on your Desktop. Once downloaded, find the file which will end in .exe and click it to start the installation. Follow the installation steps.
Step 2 – Convert your video
HandBrake has a graphic interface which is straightforward and easy to use. In the main dialog, click the Source button and choose the video file you want to convert. On the right side, there is a list of Presets, you can choose the option “iPhone & iPad Touch”.
Make sure you also check the option “Web Optimized”. The option is also known as “Fast start” or “Progressive downloading”. It places the container header at the start of the file, and allows your video to start playing while it’s still downloading.
Click Start and wait for the encoding to complete.
