CC Motion Blur does not work, because the speed up is very fast and it looks like ****.

Rendering out is not an option, because i need to constantly change elements on short notice and that would be a lot of annoying steps.

But i found a sort of solution.

With Collapse Transformation off it uses MB Shutter Angle Settings from the precomp. But with a lot of speeding up, this becomes way to blurry.

With Collapse Transformation on it uses MB Shutter Angle Settings from the main comp, but with a normal angle of 180° or 90° it is of course still way to blurry (with very fast time remapping)

So my hacky solution now is to set the angle to a very low angle setting (like 10° or something), either in the precomp (collapse off) or in the main comp (collapse on), does not matter. With fast time remapping this now becomes usable.

Pixel Motion Blur is not an option because it would blur the camera footage too, and i do not want that. Plus it does not really work good with a speed up this fast.

Just wanted to say that this just saved my day. Works like a charm, even in C4D 2023. Thanks Brian.

I got help on the Adobe forum. The trick is to use a linear expression, something like this:

mSlider=thisComp.layer("XYZ").effect("Scale")("Slider");mWidth=thisComp.layer("Text").sourceRectAtTime().width;mWidth+linear(mSlider,0,100,0,mWidth);

Thank you, -value did the trick.
