How to Play F4V and Convert F4V
Many users will ask me why the downloaded FLV video can not be played normally. It appears at approx 5% of their original width while still at full height. Namely it plays in a thin vertical strip on the far left side. Is there something wrong with the free program: YouTube FLV Downloader? No, absolutely not. It lies in the player you used.
About FLV files with different video codecs:
Nowadays there are many types of FLV files ending with *.flv. However, their video codec is different, H.264, H.263, VP6, VP6 alpha, F4V, or M4V. Some player just can play FLV with h.263, VP6, VP6 alpha and can not play other types of FLV. For not supported FLV codec type, the player you use can not recognize it. Therefore the situation about abnormal playback will appear. Especially for F4V-another type of FLV encoded with H.264 belongs to HD video. You can view this type of FLV with the better video quality compared with the traditional FLV type like H.263, VP6, VP6 alpha and so on.
Then how to view F4V normally:
In order to play F4V files normally, firstly you must choose an FLV player which can be compatible with F4V files downloaded from YouTube or other video-sharing web sites. I recommend a program called Moyea FLV Player. It can play all kinds of FLV files including F4V encoded with H.264 or M4V, regardless of online or offline videos. Moreover, it can capture a capture as the thumbnail and support full screen playback.
