Thanks sooooo much for taking the time to write these post people. I’m in a similar boat and this has been an invaluable read.

They appear to talk about Intel Iris Pro, whereas the 13″ Retina has “Intel Iris” graphics…. no pro. Anyone know if it will every be supported?

Same here latest CC as of 12-11-13 OSX 10.8.5, intermittent fails, i.e. different clip each crash. No way to pick up where left off….

It’s a texture issue. I think. I had same probs and replaced textures and it’s fixed….

I’m having the exact same issue. I’ve had it across two HDLinks now too… I’m using a Dreamcolor monitor over display port. Is this what you guys are using too?

Joshua,
That is sound logic there though. I hadn’t thought of checking it in Blackmagic’s own software. It also confirms what I thought, that it is After Effects that is out of whack. That it is a RGB to YUV conversion issue seems probable. Similar in a way to playing back RGB Photo JPG movies in FCP, which display inconsistently, but render correctly… It would be great if After Effects would render in YUV too…

Its ‘kinda’ true. ‘Most’ PAL DVD players will play NTSC. Some need to be set up to output a PAL signal to the TV. For instance, my DVD player used to output an NTSC signal to my TV, which was PAL only, until I changed the settings.
So it is a ‘to be sure’ situation.

Thanks so much for your responses. Unfortunately the Sony J30-SDI deck we got didn’t have component after all… so I have captured as DV and it seems to key ok, for the purpose. I imagine I’ll render the final cut as uncompressed so it doesn’t go through the DV ringer too many times.
I’m using Primatte Keyer Pro in FCP which seems superior to the built in keying, and the chroma footage is very well shot which is making it easier.
Cheers,
Nils

OK,
If it happens as you scale the image then you can apply the noise to the clip at this stage – no need to nest it or pre-process it.
In FCP use: Effects/Video Filters/Stylize/Add Noise
Set to, Gaussian, monochrome, rest to default, then set amount to 0.01 and increase until it eliminates banding but before you notice it.
Not sure if you need to auto animate or not, I’d say if you can see the noise then you need to animate it – or it will appear unnatural, otherwise leave it as static.
This is a trick that designers use all the time when making gradients in 8-bit design files. It is worth remembering that most broadcast work will end up being displayed as 8-bit ultimately (i.e. high bitrate MPEG2) so working in a 10-bit workflow doesn’t guarantee that the end viewer wont get banding. I’d say the reason you are getting banding is because your image is ‘too clean’.
Cheers,
Nils

The normal way to avoid banding when manipulating images is to add a bit of gaussian monchromatic noise to the image in the step before whatever it is you do that causes banding. you have to play around to get the right balance of noise/banding.
Its the same principal as dithering in gif images…
