Your comp is 8 bit color depth, so it is useless to force 10 bit with Maximum Bit Depth.
Is there a specific reason for the use of the alpha channel?
I've never seen an AE comp get altered by bringing it into PP. First thing I'd ask is how are you monitoring this?
I had this happen to me several times when using a sub-clip and sending it to AE.
I will see if I can reproduce this error again.
Thanks for the replies.
Harm: The AE comp is in 32-bit/channel (Float) color space. There is no alpha (or there is a completely white alpha).
Jim: I am monitoring this on my computer monitor, no external monitor.
Pharth: I am bringing this into PPro via: File > Adobe Dynamic Link > Import After Effects Composition...
Here are a couple screen caps to illustrate what I'm getting.
Are you using color management in After Effects?
Yes. The example images I posted have color management on in AE.
If I turn it off, the color in PPro is the same.
Can you explain why this works like this?
PP doesn't offer color management.
Jim is right.
Here is a relevant except from the color management section of After Effects Help:
"Previews sent to an external video monitor are not color managed. The color values sent to the video monitor are from the working color space for the project. To preview video colors, choose a value for Working Space in the Project Settings dialog box that matches the color space of the preview device.
Similarly, colors in a composition sent to Adobe Premiere Pro or Encore using Dynamic Link are in the working color space of the After Effects project.To manage colors in a dynamically linked composition or for video previews, create a new composition and nest your composition within it; then apply the Color Profile Converter effect to the nested composition, with Input Profile set to Project Working Space. For video previews, then set Output Profile to match the color space of the video preview device. (See Color Profile Converter effect.)"
