Flash Video is a container file format used to deliver digital video content (e.g. TV shows, movies, etc.) over the Internet using Adobe Flash Player version 6 and newer. Flash Video content may also be embedded within SWF files. With the flash videos becoming more and more popular, it's important and useful for you to know more about flash video formats.

Flash Video Formats: FLV and F4V

Flash Video has long been the standard video format used by nearly all embedded video on the internet including the videos found on YouTube, Hulu, and many more websites. There is a video file format known as Flash Video: FLV. Standing for flash videos, FLV is a file that uses Adobe Flash Player or Adobe Air to transmit video/audio over the internet.

However, FLV isn't the only Flash Video file format. Adobe products, as well as third-party programs, also may use the F4V, F4A, F4B, or F4P file extension to indicate a Flash Video. F4V builds on the open standard ISO/IEC 14496-12:2008  (MPEG-4 Part 12) ISO base media file format and supports H.264/AAC–based content. It has a flexible structure and defines specific supported codecs and extensions, facilitating simplified interoperability across tools, services, and clients.

Differences Between Flash Video Formats

The FLV format was originally based on the H.263 (FLV1) video standard. Since the release of the Flash Player 8, there has been supported also for the On2 TrueMotion VP6 (FLV4) codec, which provides a higher video quality at a lower bit rate. The current version of the FLV format also supports the new H.264 (MPEG-4 Part 10) codec, which offers a significantly better quality/bitrate ratio. Thanks to it, Flash files can contain high definition quality videos with an ACC sound.

The F4V format is also similar to FLV but since the FLV format has certain limits with H.264/AAC content, Adobe developed F4V as an upgrade. However, F4V doesn't support some of the video and audio codecs in the FLV format, like Nellymoser, Sorenson Spark, and Screen.

F4P is another Adobe Flash format but it's used to hold DRM protected MPEG-4 video data. The same is true for Adobe Flash Protected Audio files that use the .F4A file extension.
