1 MB 30 ns Video Field RAM
digitizer uses 4:1:1 video sampling, Prism24 uses 4:2:2

optional Prism 24 () Digital Video Processor and Time Base Corrector module

the Prism 24 activates the 23 pin video connector
it can pass-through the digitized video or perform red, green, blue, colour, brightness and contrast adjustments to the output
adds genlock capability to the FrameMachine, taking the Amiga's video signal from the video slot
the genlock features are:
- FrameMachine mode
- Amiga mode
- Amiga over FrameMachine Key mode
- FrameMachine over Amiga mode
- "B0-Keying" mode (color B0 is transparent)
with FrameMachine's realtime video features, it can do PIP (picture in picture) of real video and computer video on one screen
combined with a standard external Amiga Genlock, there is also the possibility to do PIP of two real video sources together with an Amiga overlay
AGA compatible Prism 24s have jumpers which allow the selection of the machine type
