Transform effect + shutter angle is messing up clip position

[petrosmarcos]

Hello!

I am using the transform effect for minor animations because of its motion blur abilities when using shutter angle. Lately however it seems like the shutter angle is messing with the positioning of the anchor point or something like that.

For example I wanted an image to rotate a couple times around its own midpoint like a wheel, this worked perfectly fine, then I adjusted the shutter angle to simulate motion blur and all of a sudden the image is rotating around a point somewhere just offscreen. 

The same thing happened when I did only a small scale animation, I made an image pop out a bit by having the scale increase in a short amount of time, then I adjust the shutter angle and now it doesn't pop out of its own middle but from some angle in the screen. 

The amount of shutter angle does not matter, it either does not happen when it's off or happens all the way when either barely or fully adjusted.

Am I goofing? or is this not supposed to happen? Any advice is appreciated!!

And we're all forgetting that using the transform effect to acheive motion blur is a workaround in itself. Motion blur should be a native option in the "Motion" section like it was in Final Cut 7 15 years ago!

@camerons17794153 You say it's a workaround. You say Motion Blur should be a native option under Motion properties but it isn't. How else can Motion Blur be applied to effects? Are you speaking of adding an adjustment layer and adding the Transform effect to the adjustment layer?

I think he means just like after effects still has the option of just toggling the motion blur per layer. The animations I'm doing in premiere are just as easily done with just default motion so I never actually need the transform effect but transform is the only way to add motion blur, how is that not a workaround?

No, I get it. It almost sounded like he was eluding to another way to do it.

"It's not a bug in the software; it is a feature of the way the Transform tool works. Recently, I was working on a 1080p timeline and added an 8K clip. I wanted to zoom in and out on a specific part and also add motion blur. When I added keyframes for scale, everything looked fine. However, when I added a shutter angle, the clip's position got messed up.

The reason is the anchor point. The anchor point is the center of the clip, and different resolutions have different anchor points. You just need to set the anchor point of your clip to match the anchor point of your timeline. For example, the anchor point of an 8K clip is (3840, 2160), and for a 1080p timeline, it is (960, 540). Replace the anchor point numbers of your clip with the anchor point numbers of your timeline.

Then, change the position of the clip to center it, but do not change the position using the same Transform effect. Instead, change the position value from the Motion tab at the top of the Effect Controls panel. You can also add another Transform effect, but make sure to place this new Transform effect before the main Transform effect where you changed the anchor point."
