This Flash Video format is compatible with the flash video playback and Adobe Flash Player software. Boxes are used for the storage of data and it supports h.264 video and AAC audio compression standards. The F4V files are of greater quality than the FLV, however, it will require the latest version of Flash (9.0.115 or higher) and a processor with a good speed.
Developers are gradually being encouraged by Flash developers to move away from the older version FLV format and accept F4V. Therefore, the F4V files will overcome the shortcoming with the old FLV structure when streaming H.264 or AAC. Besides, the F4V is patterned according to the ISO base media file format. The ISO base media file format defines the general structure for time-based multimedia files like video and audio and also used for other formats like 3GP and MP4.
