In this video I show how to convert .mov to .mp4 file on Linux using graphical app (Handbrake) and command line tool (ffmpeg).
This tutorial focuses on ensuring wide compatibility of the video after conversion, so that it can play on almost any device.
I showed settings that need to be applied to make sure that footage shot on iPhone can be opened almost on any device. iPhone often writes .mov files using modern H265 codec and 10 bit color depth which although produces videos of higher quality and efficiency, sometimes lead to compatibility issues on some phones.
