Creating panoramic HDRs is not an easy thing to do. First, you can’t just snap a normal photo or series of photos. HDRIs require multiple exposures (bare minimum of three) for each frame at different shutter speeds, which must then be combined in an application like PS. It’s possible to do with a regular camera, tripod, and panoramic head, but with so many exposures it can be a challenge to get everything to line up.
Another option is to photograph a mirrored ball, which can be anywhere from around 4″ to 16″, and then use a polar coordinates filter to unwrap. That can be effective for capturing the scene’s lighting, but it won’t give you a high-quality image to use as a background.
There are dedicated rigs you can buy for creating highrez HDRIs, but they are quite pricey. It may be possible to rent one, but I don’t have a source offhand.
I don’t know if they’re still available, but there used to be a company that made a special lens for snapping 360 panos in one shot with select digicams. These were relatively affordable, but of course you’d have limited resolution with that.

The easiest way to do it would be to give your plane a white material. Then drop your video material on the plane and set it’s texture tag to Flat projection. Then use the texture axis tool to scale the projection smaller than the plane. That’ll leave the white border around it.

The stage object has to be higher in the object manager than any of your cameras. Otherwise the camera will take precedence.

Um, parent it to the null with the external compositing tag.

The mis-named “Center” function will also do what you want(Functions>Center).

Maybe some of these? https://www.lowpolygon3d.com/CCP6/index.php?app=ccp0&ns=catshow&ref=3D+model+people

Unfortunately that’s a limitation of the motion vector pass — it doesn’t take camera animation into account. So, you can either render twice (once without the blinnking lights, then just the lights to composite over the blurred render), or do motion blur in Cinema.

You’ll have use a little Xpresso to get the coordinates of the points that are being deformed by the spline wrap object. Here’s an example: https://www.3danvil.com/tutorials/spline_wrap_AMT.c4d
What this does is get the position of the deformed point, attaches a null to that point, and assigns the external compositing tag to that null.
I chose a point on the leading edge of the cube, but you can pick any point you want by opening the xpresso editor, clicking on the point node, and entering a different point index number.
To figure out the index number of a point, go into points mode, select the point, and look in the structure mananager (set to points mode) for the point that’s highlighted.

It should work if you put the material and the stick texture tag on the Extrude nurbs object.

I’d start by creating a polygon primitive, checking “triangle” in the attributes manager. Then I’d go into poly mode, select it, and extrude upwards a little with the caps option turned on. Then I’d select all the points of the top face and run the Weld command, which will give you a squat, three-sided pyramid. extrude out the pyramid sides and weld the points of those faces to give you the basic logo shape.
