Besides, you can only upload an AVI file on YouTube and Facebook but not on platforms like TikTok and Instagram. These video files are supported by VLC media player, not QuickTime, Apple's default player.

MP4 is a widely used digital multimedia container format. It was developed by the Moving Picture Experts Group (MPEG) and is known for its efficient compression capabilities. MP4 files can contain audio, video, subtitles, and even images, making it a versatile choice for various devices and platforms. You can be easily uploaded on Instagram, TikTok, YouTube, and Twitter. Besides, it is supported by Windows Media Player, QuickTime, VLC, iPhone, Android, iPad, and more media players.
