A simple test procedure Apple could use in internal QA is something like make an uncompress movie (with 0.91 PAR) that is just alternate 1,0,1,0 for pixel values (ON/OFF) repeated at all frames... (you could maybe if this could be more then 8 bit do something that looks like a bit like a bayer mosaic ant set the alternatively R then G then B ON value to something not 1.0 to allow you to catch 8 bit in pixel path, and gamma or pixel order out of wack). make a plugin that reads a frame at another time (A), reads a frame from that movie copy using the clip well (B) , and reads the main input (C), plugin loops through pixels and does a diff of A to B (if pixel is different r=1,else 0), and B to C (if pixel is different g=1,else 0), and C to A (if pixel is different b=1,else 0). For more complete case replace last diff by a procedural one that redraws the mosaic and where ON level is equal to the float value level that is equivalent to the rounded value on either 0-1023 or 0-4095 levels scale used to make reference test pattern movie source. Make a template at 1080p square pixel with that fabulous effect load SD res movie and apply template in FCP-X... repeat software and hardware. If you don't get a constant black image, bug!
That's a really great idea. I'm actually working on improving our automated testing, so this will help a lot.
