TRANSFORM EFFECT NEEDS TO BE ADDRESSED
The transform effects is always buggy yet is one of the most essential effects used in almost every project.
Some examples:
Using a manual shutter angle of 180 messes up the scaling/anchor point of the clip.
Bugs with scaling effects/animations. When I scale down to 0% on a keyframe, sometimes the clip just jumps up to 25-50% for no reason.
Address all the other posts/bugs about this.
What's the point of using this effect if the majority of its functions don't actually work? STOP MAKING NEW FEATURES AND MAKE THIS SOFTWARE MORE STABLE.

This bug means that in fact you cannot zoom a GFX with motion blur!

This is a BUG. I have exactly the same issue. If you use Transform Effect, and a Scale is manpulated, the anchor point is set to some random location. That location moves depending on the Shutterspeed setting. The higher the Shutterspeed, the further the offset.
