When I increase the shutter angle in the transform effect, the anchor point seems to be moved to the upper left corner. I've read that I should disable gpu acceleration, but this makes everything slower and it also removes the motion blur I want.
Sorry for the issue. I tried adding the transform effect and changing the shutter angle of the clip, but that did not change the anchor point. Could you let us know which Premiere Pro version you're working on? I recommend trying the 23.2 version if you haven't updated it yet. If you see the issue on 23.2, please share a screen recording so we can share it with the engineering team.
This has been happening for years if you just do a quick google of the problem.
It occurs more when you're adding a PNG and the anchor point is different to that of the actual sequence, doing a simple pop in on scale transform works perfectly until you try to add motion blur with shutter angle, then suddenly the image is flying across the screen
You can see it in the screen shot attached, the scale pop works perfectly fine until shutter angle is added, then suddenly it is flying across the screen to get to the point it's supposed to be at
This is exactly the problem I have
Anything that moves the Anchor point after other animation for size/placing has been done has weird affects on the previous work.
So for this, to keep it from affecting previous work ... and for any other effects that muss up previous work (and there are several) ... you need to NEST before applying the Shutter Angle.
That ... normally allows you to work as you expected. Either way, if that fixes this or doesn't for you, please post back. These sorts of things are very useful for other readers to know.
Nesting didn't fix it either sadly
Thanks for the note. I was not able to reproduce the issue with position keyframes. I saw motion blur as expected. Any steps I can try in order to reproduce this one so we can file a bug?
Hey Kevin, in my experience, motion blur doesn't work properly with rotation and scale if the footage's size is different than the sequence size.
To experiment try the following: in an HD sequence, create a Color Matte with size 200 x 100 px, add Transform effect, animate rotation, everything looks normal, now if you change Shutter angle value, everything will be messed up.
But if you nest the same Color Matte, which makes it the same size of the sequence, and add the transform effect after that, everything works fine, but moving anchor point around will be a little bit tricky.
Only workaround I found for this long standing bug, is to manually adjusting the achor point and position values in the Transform effect to match those that are shown in the Motion tab.

Suggested nesting is a great idea, but you have to follow the order explained,
this is very important, so if you have other effects applied, all these need to stay
on the clip, nest your sequence and apply the Transform Effect (with Shutter Angle) alone on the nested one.
Transform(shutter angle) usually misbehaves when other effects are applied.
Other suggestions is if you can share with us screenshots from the Effect Controls Panel,
sometimes offsetting the order of effects does affect the way they behave, especially when applying
the Transform Effect.
If it stucks, you have another option to keyframe a manual directional blur or something like that.
@Kevin-Monahan I do suggest a Motion Blur feature like in After Effects, for Premiere Pro by the way.

just add elements having same resolution to that of stage, like if you need a pic then add that image to canva for eg 1080 x 1920 frame(place the image in the middle of the frame) then download transparent image, boom now shutter angle wont cause any issue.
Yes!! this should be marked as the answer.
I wanted a png of a disc to spin in from the right with motion blur. I tried everything mentioned above and every time I added the shutter angle the postion was thrown out of whack.
I created a transparent image the same size as my sequence and placed the disc in the middle. Then imported it and I could do everything I wanted from there.
It shouldn't be this way, but this work around has saved my day!!
Anchor points are frequently a massive headache in Premiere, and the order of when you move them MATTERS ... huge! I avoid touching the Anchor points whenever possible.
We're moving from the shop we've been in for 45 years, and unfortunately my desktop is all packed (including the what, 15 peripherals, 4 USB busses, and several cameras, the Atem mini Pro, Elements panel, et al ... a hundred cords or so ... how do we accumulate all that stuff?). So I can't test this to make sure.
But for this work, my recollection is you can either move the matte, then nest the matte, then apply shutter ... or ... center the matte on the screen which is a bit of a pain for 'larger' mattes than the screen ... dead center, please! it's obvious later if it ain't ... then make sure the Anchor point is in the center of the matte and screen at same time ... then apply the shutter angle effect.
If you apply the shutter angle before changing the anchor point ... the behavior is just bizarre.
I just switched to the free version of davinci resolve. No problems, no bs, no headaches. Fixed all of my problems I had in premiere👍
Use the tool what works. I use both daily, and participate here, BM, and colorists forums.
Ain't none of these apps totally stable and working for every user.
So ... use what works for you to get the stuff out the door to the nice clients what pays your bills ...
