We will explain the difference between MP4 and MOV, the reasons behind data corruption, and how to repair MP4 and MOV files. Part 1: Major Differences Between MP4 and MOV Video Formats MOV, developed by Apple, and MP4, developed by ISO, are among the most used video format in the digital world. MOV is the default and goto format for all Apple devices, while MP4 is supported by all operating systems, video players, and editors. MP4 and MOV work on the lossy compression algorithm, but MOV still retains high quality and boosts larger video. Regarding size scalability, MP4 is ideal as it could be scaled to the desired size while maintaining quality, though not as high as MOV offers. Due to its ability to retain high quality and being easy to encode, MOV is widely popular when it comes to professional video creators. MP4 is mostly popular with content creators due to its availability on a wide range of devices and flexibility regarding file size.
