Colorama is a 16bpc effect so it shouldn’t be too problematic to use it in a 32bpc linear project.
If you want the Colorama effect to treat the source footage as it would in a non-linear project then you’ll need to de-linearize (re-gammify?!) the footage before the Colorama effect. You can do this easily with the Utility > Color Profile Converter effect. With the default Color Management all source footage is converted into the linear working profile, so you can set the Color Profile Converter’s Output Profile to the source profile of the footage to de-linearize it. Example settings might be:
Input Profile – Project Working Space
Output Profile – HDTV (Rec. 709)None of the other parameters should need changing.
The footage will appear washed out in the linear working space but the color code values of the footage will be the same as if the project were not using linear working space. This is valuable because Colorama is expecting perceptually linear (gamma encoded) color values.

Which video are we talking about?

[Diana Jordan] “Am I missing something or was my process completely wrong? I would really appreciate any help. I scoured the internet all day and haven’t found the advice I’m looking for. Thanks in advance!”
Generally if you have 3D locators and a 3D camera that matches your scene I’d recommend parenting the 3D screen footage layer to one of the 3D locators to get it in the right spot. If you choose to parent to the upper left screen corner locator then you could set the anchor point on the 3D screen footage layer to the upper left before parenting. If you hold shift while parenting the 3D layer’s anchor point will snap to the 3D locator’s anchor point. From there it’d just be a matter of rotating the footage into place if necessary (sometimes a 90° flip on an axis or two, or a 180° flip).
[Diana Jordan] “Anyway, the pins don’t stick in the right position. Sometimes you can’t see the video. It disappears once the pick-whip is done.
“If you’re set on using the corner pin effect then you need to translate the 3D coordinates into 2D composition coordinates using an expression. In this case your footage layer should not be 3D; the camera projection + corner pin would double up on the perspective distortion and cause all kinds of whackiness.
The expression to convert 3D coordinates to 2D takes this form:
layer = thisComp.layer("Locator_01");
layer.toComp(layer.anchorPoint);Where “Locator_01” is the name of the 3D layer. This returns the 2D projection of the 3D point in composition coordinates. You would apply this expression to the corner pin property that you want to line up to Locator_01.

You can also use the Compositing Tag to force QMC sampling on only certain surfaces.

Can you share one of the offending EXRs?

If you add any effects or layer styles to the pre-comp that has collapse transformations enabled then it will break the “pass-through” of the blend modes. The blending mode of the pre-comp should be “-” as in the image Bryan posted, if it’s anything else (e.g. “Normal” or “Add”) then the blend modes inside the pre-comp are not being used.

I realize it’s been several months, but I’m still very much interested in seeing your examples.

[Nathan Scofield] “Would working in higher bit depths and then exporting back to 8bit h.264 for example not just reduce the quality to the same state as if I worked in 8bit to begin with while animating?”
The compositing process essentially performs mathematical operations on color values. If you perform math using more accurate values your results will be more accurate.
The outputs are the results encoded. With lower bit depths/accuracy while compositing errors can end up summing and multiplying to produce greater errors and as a result the output will be of a lower quality. The more math is being done during compositing the more potential error will be introduced into the output at lower bit depths.

Have you found any time to share some examples?

In many cases the Text Animator feature will do what you want. If need be you can even select single words from the text layer to animate in their own way. However, you might end up with lots of text animators applied to a few text layers.
In any case, I recommend you look into text animators in the documentation.
