  Color strobing on 10-bit Blackmagic AE render

  **THIS POST IS ALSO IN BLACKMAGIC & FCP FORUM**

  I’m trying to render an animated shot out of After Effects to bring into FCP 5.04, but everytime it renders down at 10-bit Uncompressed 23.98fps, I’m getting strobing on a portion of the image that is suppossed to be solid red.

  In After Effects and in Final Cut the image does not seem to be strobing, but when sent to a TV there is definite strobing. Not thin line interlace strobing, but off frequencey (like a flourescent light) strobing. The red is phasing from two types of red back and forth very quickly. It does not happen when I fast forward through the footage or scrub through the footage, but if I play it down in FCP w/ the BM easy set-up 10-bit 23.98, I get strobing.

  I rendered the same file down in AE at Photo-Jpeg 75% and the strobing dissappeared, but of course, we are working at 10-bit, so I need to find out what’s causing this, and if it’s going to be an issue elsewhere.

  I’ve got the latest verison of the BM drivers: 5.7.2, but I’ve tried rendering it on several computers to no avail (a PC, and two Macs (one with 5.4 drivers)). I’ve got a BM Extreme Card, and like I said FCP 5.0.4.

  Any info would be MUCH appreciated.

  Thanks,
  Sam

  hiya – i’m having a similar problem with a blue/purple section of my animation phasing. Im also using blackmagic, after effects and fcp. Did you manage to solve it as it’s only happenening sometimes for us, making it very difficult to locate the source of the problem? Any help would be much appreciated

  cheers damian
