Description .ASF is a file format created by Microsoft, formerly known as Active Streaming Format or Advanced Streaming Format. ASF is specifically designed for streaming audio and visual content. ASF files are containers for the streaming media, and normally Windows Media Video or Windows Media Audio files are found within them. This format has been superseded by WMV.

Technical Details An .asf file may contain video and audio, and can also contain metadata in the same way that MP3 files do. This allows the definition of artist, album etc. The file format allows streaming in a similar method to other formats, allowing the user to view the file once a certain amount of bytes have been downloaded. The file continues to download while the user watches. Due to it being designed for streaming, one disadvantage of ASF is that the maximum resolution is a relatively small 352x288.

Technical Details Flash Video FLV files contain video bit streams which are a proprietary variant of the H.263 video standard, under the name of Sorenson Spark (FourCC FLV1). Sorenson Spark is an older codec for FLV files but it is also a widely available and compatible one, because it was the first video codec supported in Flash Player. The Flash Video FLV file format supports two versions of a so called 'screenshare' (Screen video) codec which is an encoding format designed for screencasts. Both these formats are bitmap tile based, can be lossy by reducing color depths and are compressed using zlib. The second version is only playable in Flash Player 8 and newer - Audio in Flash Video files is usually encoded as MP3. However, audio in Flash Video FLV files recorded from the user's microphone use the proprietary Nellymoser Asao Codec. FLV files also support uncompressed audio or ADPCM format audio.
