If you render the screen black then making the screen appear behind the reflective glass isn’t too tough in composite. The aptly named ‘Screen’ blend mode does a great job.
Pretty much the only time I ever consider rendering screen content in 3D is when I need reflections or illumination from the screen to fall on other objects.
Even then I’ll sometimes render a UV map of the screen + reflections to map the texture in post.

I’m going to guess that the delay effector is the source of your troubles. There are two possible problems.
1) The delay effector in R15 has a tendency to forget to work, so it’s possible that the C4D scene is not delaying the object but the delay is being properly added in the compositing information. The only way I’ve found to ‘wake up’ the delay effector is by dragging it’s strength value in the attribute manager a little bit (do NOT type in a value and press return/enter).
2) The delay effector is working properly in C4d but not through the cineware/AEC pipeline. In that case you should apply a MoGraph Cache tag to your Fracture and cache it. Honestly I’d do that even if it turns out #1 was the problem. For animations that require data from previous frames (e.g. dynamics, delay effectors, etc.) you should always cache.
The easiest way to confirm that the delay effector is the issue would be to disable it and see if things line up in AE.

I usually either double click the keyframe in the graph editor to pull up velocities if I need specific values or I drag them out in the editor if eyeballing will do it.
I’d like to see a shortcut for advancing to half way between the current time and the next/previous keyframe but that’s only going to help for adding keyframes not modifying.

Answered this on another forum but perhaps you check here more often:
clamp(0;1;t-id/5)
The divisor value can be increased from 5 for more overlap or decreased for less. When it’s 1 you should have the same animation you currently have.

[Jordan Montreuil] “The highlights are not from the source footage, they are from layers I am compositing over the top of the source footage.”
Well that may complicate or simplify things. The easiest way to bring down the highlights in that case would be to dim the “highlight” layers you’re placing on top. How that’s done may be complicated depending on what the effect you’re trying to achieve is and how you’re going about it.
However, if you want to keep the “look of the comp” then you might be satisfied with reducing the over all exposure. That will definitely dim the entire comp but will keep the relative scale between the brights, mids and darks the same.

[Jordan Montreuil] ” I am working with PR 422 but have an original RED raw source.”
I’d work with the R3D source. That’s going to give you the best chance of recovering highlights possible.

You could use an adjustment layer with levels to invert the image and multiply it back into itself. The nice thing about using levels to do this is that you can change the intensity of the invert to get different amounts of rolloff in the highlights. You’ll also want to tint the footage on the adjustment layer (so that it doesn’t desaturate) and apply a small blur (to preserve edge detail).
Here’s a sample file. Note that it’s important the levels effect has clip black and clip white turned on. Also note that the adjustment layer is not at 100% opacity. Try changing the input black, input white, gamma and adjustment layer opacity to see how it affects the adjustment.

[Roger Heyward] “I’ve tried to right-click in the Viewport, with objects selected and unselected. I’ve tried looking in Main Menu/Tools and Main Menu/Mesh.”
The Knife and Extrude tools are in the Mesh > Create Tools sub menu.
If you are using Cinema 4D Lite then you don’t have access to these (and other) polygon modelling tools.

Here’s an animation preset that will center text vertically.
7634_centertextvertically.ffx.zip
The preset applies two sliders to the text layer. The first one needs to match the line height of the text and the second defines the maximum number of lines the expression selector will work with (if more lines than that value are entered then it will no longer vertically center, use a high value).
It also applies a text animator and expression selector that work together to offset the anchor point of all lines of text by the same amount based on how many lines of text there are.
This works with paragraph text or point text. There’s no way to dynamically resize a paragraph text layer’s bounding box so you’ll likely need a very tall bounding box if using paragraph text. You may need to adjust the layer’s anchor point some to get the positioning you desire.

[Adam Trachtenberg] “Otherwise, if you have Sketch & Toon that may be the way to go. It’s a bit complicated but it can render splines without adding geometry.”
You can also use Hair materials to render splines directly without geometry. It’s a little more straightforward than Sketch & Toon.
