F4V is a flash video format that is an upgraded version of the FLV format, and it is created using Adobe Flash. The FLV format has some limitations with the H.264/AAC compression techniques, but the F4V file doesn’t have it.

Today, the F4V format is quite popular, and the user can watch online HD videos without any buffering, blur, or break. Users can also download the video in the F4V format and play them on flash supported media players like VLC, QuickTime, and MX Player. But the F4V file also faces challenges of compatibility with some codecs like Screen, Nelly Moser, and Sorenson Spark.
