About ASF
ASF is the container underneath Windows Media: WMV and WMA files are ASF files with a more specific extension. It was designed for streaming and can carry timed metadata. Older IP cameras, TV capture cards and Windows recordings still write it.
ASF is a Windows-era container that phones, Macs and browsers do not open directly. ASF is accepted by Windows Media software and some older cameras and recorders.
