FLyer: Video capture Processing/Audiocapture. REquired a feed from the toastercard. and a TBC input:
TBC-IV: Required by the flyer when capturing from analog videotape. Digital mini-DV tape does not need a TBC, neither does Over the air TV, Cable BOx output when you feed a toaster/Flyer. Anthything with Macrovision protection turned on (VHS rentals, DVD's) have macrovision so you have to run them through a TBC
PAR: Can live in a Toaster FLyer system with a TBC and can feed one of the Toasters inputs. The Par Acts like an extra DDR.. Connecting that old IDE drive may not be as easy as you thihnk. PAR was very picky with the drive requirements.
If you have the AD516 card you can also capture audio too...and sync it with the par.
To be honest the best most economical animation output device for an Amiga animation is a PC with TV out.
Any kind of Amiga animation is done so much easier on a PC or Mac these days. Having this equipment is more nostalgia then functionality.
The flyer, for cuts only and non layer intensive video is really good. It also loved when you feed it digital tape (low to no noise.
