The PAR's main use is when your target output is live analog video, either NTSC or PAL, for instance as one input to a Video Toaster, showing long Lightwave generated animations in real time. If your target is digital, such as some type of MPEG compression, it would be of no advantage.
The other use is coupling a DPS PAR with a DPS TBC-IV. You can then capture and play back live video or images, not just animations. Makes a neat stop-motion or time-lapse recording setup. I am working on a dual PAR+TBCIV setup to record stereo video since the TBC's can be genlocked to synchronize the 2 video streams.
