I'm on mac 0S 10.8.6 SNDX V 5.5.3.7. I've always done QT ref exports of my shows to maintain the audio stems. Now we've gone HD. The AEs captured DNX220X which created issues with BCC 5.0.4 renders. I posted about this in an earlier thread and it seems there is some issue on my system or maybe a bug that won't render 16 bit effects processing on some if not all of the BCC 5.0.4 effects. I found that if the media is DNX220 then when set to automatic processing the BCC effect render okay. I've now asked my AEs to capture everything DNX220. Now I have sequences with a mixture of DNX220 and DNX 220X. I find I can export a QT ref and then save as a self contained movie in QT Pro 7.6.6. I always check my files with an ama link back to make sure the levels are correct.
I've noticed on our first HD episode the ama link had whacky blown out like posterized levels in some sections of the show. Scrubbing up and down and back to the section and it was okay some of the time. Now on episode 2 the whole show where ever there is source video and not graphics alone is showing the same whacky levels. Color bars are fine as is a texted credit back plate.
I've pulled some sections and examined the reference and render clips. For color bars the media is DNX 220. For sections of the show the media is DNX 220X and for the Safe Color Limit Rendered Track the media is DNX 220X. My exported and self contained files look fine in QT pro and if I do a traditional import back into Avid they are fine. It's just the ama link that is whacky.
Could these issues be the mismatch of bars at DNX 220 and most of the source material and safe color render being at DNX 220X? Also on the ama linked clip back to the episode the color space says 601 while when I check the safe color render media in avid it's 709. Not sure what's up any suggestions? The network has not complained about the files so they must work for them too.
