10 Bit monitoring graphic banding issues Premiere/Decklink 3D
on Aug 15, 2012 at 8:56:42 am

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 an animated gradient in a 10 bit Sequence.
10 bit Playback settings from the Decklink to a AJA HDP2 through a Dreamcolor.

Render timeline.
Perfect Smooth gradient on the Dreamcolor

I do the same in Premiere CS6 with a 10 Bit Sequence, 10 bit playback.
Result: Banding all over the place

The Video Preview in Sequence settings was set to YUV 10 uncompressed. Playback quality on Full ofcourse.
With ProRes 10 bit , it was no difference.
Real time monitoring is still full of banding. Playback quality on Full

It's easy to reproduce.
You can use any 10 bit gradient or blurred circel.

Create a animated Gradient or a blurred circel in a 10 Bit FCP sequence. Export with current settings.
Import the file in Premiere. And try to get a proper smooth 10 bit image on a 10 Bit Monitor.
That same quicktime file works perfect when importing back in FCP7 and playback Blackmagic 10 bit.
The gradient is ultra smooth.

Not in Premiere.
It's the same on multiple Mac systems with Decklink 3D cards.
If you're doing graphics this is really an issue.
The renders/exports are fine, but the monitoring is a problem.
