A Video Floppy Disk is a video storage medium in the form of a 2" magnetic floppy disk used to store still frames of analog composite video. A video floppy, also known as a VF disk, could store up to 50 field images or 25 full frames either in the NTSC or PAL video standards. Some brands also provided a short audio track with each video image.
The obvious limitation is that the playback system is roughly equivalent to the operation of a paused video recorder. Since the video is stored as a conventional video frame in a format such as NTSC or PAL, the resolution is limited to that of any other video. And since the images are not stored digitally, transferring the photos to a computer requires a video capture card.
