Banding issues 10 bit monitoring in Premiere CS6
I’m having problems getting a proper 10 bit output to my Dreamcolor monitor from Premiere CS6.
It works perfectly in FCP7 but not in Premiere CS6
I’m using a Decklink Extreme 3D.Because this setups works perfectly in FCP7, i assume this must be Premiere/Decklink related.
In FCP7 i create a animated gradient in a 10 bit Sequence.
10 bit Playback settings from the Decklink to a AJA HDP2 through a Dreamcolor.Render timeline. Result:
Perfect Smooth image on the DreamcolorI Do the same in Premiere CS6 with a 10 Bit Sequence, 10 bit playback. Banding all over the place.
It’s easy to reproduce.
You can use any 10 bit gradient or blurred circel.It’s the same for After Effects.
Any ideas?

In Premiere Pro if you have the Video Previews set to I-Frame MPEG you’ll never get a clean 10bit render because that’s a very lossy compression.
Switch that to DNxHD or ProRes 10bit and you should get a cleaner render. That’s what we do for all final renders from the Master Timeline.

The Video Preview in Sequence settings was set to YUV 10 uncompressed.
With ProRes 10 bit , it was no difference.
Real time monitoring is still full of banding.
My problem isn’t the render. I need a full quality blackmagic 10 bit playback on my Dreamcolor during edit.You can easily test this. Create a animated Gradient or a blurred circel in a 10 Bit FCP sequence. Export.
Import the file in Premiere. And try to get a proper 10 bit image on a 10 Bit Monitor.
That same quicktime works perfect when importing back in FCP7 and playback Blackmagic 10 bit.
The gradient is ultra smooth.Not in Premiere.

I challenge anyone to test this. It’s not an isolated issue.

Paul,
I’m having the exact same issues running the same setup as you are: A mac pro running both windows and osx, decklink hd extreme 3d, aja hdp2 and hp dreamcolor monitor. I know it used to work when i just bought the kit. Now when i open up after effects (i’m more of an online guy) set my project to 32 bit, add solid, slap on the gradient and output results in…. BANDING! D&mm!t! Not what i invested in… No 10 bit output on my dreamcolor.
Also i’ve contacted my hardware supplier who run the same setup, they too had the same result. Again, works fine in fcp7. They were to investigate, have yet to hear from them.
Also contacted blackmagic, no reply…
I feel lost here… no-one seems to care 🙁
