What is MP4?

MP4, or MPEG-4 Part 14, is a multimedia container format that is commonly used to store video and audio files. It is a very popular format for online video streaming, as well as for storing video files on smartphones, tablets, and other devices. MP4 files can be played on a wide range of devices and platforms, including Windows, Mac, Android, iOS, and more.

What is FLV?

FLV is a video file format that was developed by Adobe Systems for use with its Flash software. It is a popular format for online video streaming and is often used for video content on websites such as YouTube and Vimeo. FLV files can be played on devices that have the Adobe Flash Player plugin installed, such as web browsers.

Video Compression

The biggest difference between MP4 and FLV is the video compression efficiency. MP4 files typically use the H.264 codec, which is a highly efficient video compression standard that provides high-quality video at relatively low bitrates. FLV files, on the other hand, typically use the VP6 codec, which is less efficient than H.264 and can result in larger file sizes.

Compatibility

Another difference between MP4 and FLV is their compatibility with different platforms and devices. While MP4 is widely supported on a wide range of devices and platforms, FLV is becoming less common and is no longer supported on some devices, such as iOS devices.
