Anyone used a DPS PAR for anything interesting?

Has anyone here used a DPS PAR (Personal Animation Recorder) in their Amiga for anything beyond simple record/playback?  Is non-linear editing possible? semi-practical? impossible? effects? etc.?

I did use a PAR in a two-machine setup.  It went something like this:

(Slave) A2000 w/Toaster 2000, TBC IV
(Master) A2000/4000T w/PAR, TBC IV, Sunrize AD516, Bars & Pipes, MultiFace

The master machine, using Bars & Pipes, controls the Toaster in the slave machine, via a null-modem cable and the Toasty tool in B&P.  On the B&P timeline, using AREXX, it also controls the PAR in the local machine, and the TBC IV in the local machine.  Thus on the B&P timeline, a fully synchronized playback of three or more video sources could be achieved (PAR, TBC [comp/S-Vid], Toaster framestore).  Special AREXX scripts had to be designed because B&P could not talk directly to PAR / TBC (something about 'direct' vs. 'indirect' AREXX messages) -- so an intermediate AREXX port was made for each of PAR & TBC, which would listen for messages from B&P and forward them on to the DPS equipment.  With this, one could also forward these messages anywhere -- to DPS equipment over a serial port, or even DPS equipment over TCP/IP. All the while, the AD516 played back audio in sync with the B&P timeline.

Another interesting use would be to use B&P to synchronize a genlock with the PAR, and use Scala to overlay Amiga graphics onto PAR video.  'Live' compositing.  I've got plans to delve deeper into this, using a scenario like the above, except the Master machine would have a genlock, and overlay Scala animations onto the output of the slave Toaster... which of course would be mixing video from one or more PAR cards :-)

cheers,

Would I have to remove the Toaster to use a genlock?


I think not.  I think the Amiga will genlock to whatever genlock is made "active".  I could easily be wrong though, and it could even harm your computer.  But I think you can have two different devices hooked up so long as only one is "active" at a time.
