FLV
FLV is designed by Adobe for transmitting video files over the internet. You can upload FLV files to Facebook and YouTube, but not to other social media and video sharing platforms. The most compatible media player for FLV files is VLC.
FLV (Flash Video) files are used for storing videos in the "Flash VIdeo" format. However, it is not a widely-used format today, because Adobe has officially discontinued Flash. You can still create and share files in the FLV file format if you use a Flash Video exporter plug-in.
MKV
MKV contains video, audio, and text files. You can upload MKV files to Facebook and YouTube, but not to mobile-based social media platforms like Instagram. It is compatible with VLC media player.
The Matroska Video or MKV supports an unlimited number of video, audio, and subtitle tracks. It is free to use and is best for independent creators. MKV files are not compatible with Mac and must be converted before they can be played on Apple's QuickTime Player.
