ตัวแปลงไฟล์ออนไลน์ฟรี F4V เป็น WV

F4V is a Flash Video format supported by Adobe Flash Player software and all browsers with flash video playback. The container uses boxes for data storage and it is compatible with h.264 video and AAC audio compression standards. F4V files provide better quality than FLV but need a newer version of Flash (9.0.115 or higher) and a faster processor.

WavPack lossless audio compression. Note that, when converting .wav to this format and back again, the RIFF header is not necessarily preserved losslessly (though the audio is).
