What Is ASF

The ASF is known as Advanced Systems File created by Microsoft, formerly known as Active Streaming Format. An .ASF file is a container, including video, audio and metadata. It’s a specifically designed steaming media format which allows users to view and play files once a minimum number of bytes are received with the rest of download process continuing as well.

How to Play ASF File

Due to the fact that designed for streaming, one disadvantage of ASF file is that the maximum resolution is relatively small, only 352×288. Because ASF is mainly used in Windows systems, you can’t play ASF file on Apple devices and players like iTunes, iPhone product series, iPad product series, QuickTime, iMovie, Final Cut, etc. Another inconvenience is that few media player supports playing ASF, except Windows Media Player and VLC.

In order to solve this video compatibility issue and enjoy ASF files anywhere, people’s first choice is to use some tools to convert ASF file into more popular video formats like ASF to MP4, ASF to AVI, ASF to WMV or ASF to MOV, etc.

It’s quite common and easy to find your digital solutions online today, like splitting video or cutting audio, downloading videos form YouTube, converting your video file from one format to another.
