Transform effect + shutter angle is messing up clip position

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!!

Exactly which effect are you using, I can't find one with shutter angle blur.

Ignore I've just found it.

On my PC it rotates around the centre anchor with any setting of shutter angle.

On mine too, but with oversized clips that do not match the timeline, apparently you need to check Scale to Framesize first.

But this will affect the resolution (in a negative way) - noticible when you're zooming into overscanned images.

Any other effects applied to the clip? Let me know, Petro.

 

Thanks,

No it happens with only the transform effect as well. I read somewhere that this could be due to no GPU acceleration enabled, in my settings ''renderer'' is set to ''Mercury Playback Engine GPU Acceleration (Metal) - Recommended''

 

However, I am on a 2020 iMac with an ''AMD Radeon Pro 5700 XT 16 GB'' graphics card, and I have read somewhere else that premiere does not properly support this card so acceleration would not be fully functioning. Could that be the problem?

 

Thanks for your reply!!

So would you have any idea what the problem could be?

Are you using the Transform Effect?

Yes only the transform effect on a .png image for either rotation or scaling animation.

Same happened to me. So in my case, i have a video clip that is tilted horizontally. I wanted to make it upright so I added one "Transform" and change the "Rotation" of the whole clip to 270 degrees (without keyframes, i didnt do any movement, just rotated the clip). Then later on, i wanted to do a zoomed in effect of that clip. I used the same "Transform" and added keyframes for "Position" and "Scale". It all works fine, the "Transform" did exactly what I intend on using it for. The clip is rotated and the zoom in effect is present. But for the zoom in part, i wanted some motion blur, so on the same "Transform" tab, i increase the shutter angle, but the whole clip moves. It's as if it is cut off and moved off frame. Like the original comment mentioned, the value of shutter angle doesnt determine how far off the clip is messed up. It's either 0 and it's fine, or any shutter angle applied and it's messed up.

 

Sorry, this is not a solution, just want to add my side of the problem if anyone knows what's up

I have the same exact problem, I wish I could post a video. 
Shutter angle will not be applied, after using "Scale" and "Rotation" in "Transform" effects. The PNG file, in this case the logo will change position, way off centre. 
There appears to be two axis to the PNG file, and it’s impossible to align them without changing the other. 
It is a really annoying bug, as After Effects does not seem to support the animation made inside Premiere as it will not apply any blur, unless it’s directional.

I've been having this same issue for a long time. There's a workaround that works for me most of the time - nest the clip and apply the transform effect on the nested sequence. I hope this helps!

Please make sure to check the option Scale to Frame size in the context menu.

 

I just tested it on a 6K source clip on a 1080p timeline and with the option checked, rotation is from the center.

 

If you need to apply the effect to different part of the image, please scale it to the desired size first, create a nested sequence and apply the transform effect to that nest.

This is known to happen, especially if transform is combined with something else. Consider nesting

Adobe, is there a fix coming for this? It's a bug in the software. All these workarounds are cumbersome.

Hi, August 2022 and this bug is still not fixed. What do we pay you for monthly?? Buggy software with no solution in sight?
Nesting might resolve the problem, but it reduces your resolution during zoom-in and defeats the advantage of zooming into a higher-res clip.
I'm fed up with buggy software from a company that pockets millions from students and educators every year. This help post was made a full year ago and should have been an easy code fix if it only has to do with sequence/source scaling mismatch.

On top of that, Premiere is guaranteed to take a 15 second edit, and turn it into an hour-long headache of having to contact customer support about a basic effect that doesn't work properly.

Hi BB,

Effects construction can be exasperating. Sorry! I think it helps to know that video effects work by mathematics: for example, RGB values get plugged into virtual arrays for some effects. Things like that.

 

What's not widely known: the math for effects needs to obey a particular order of operations, referred to as the "render order pipeline." To place certain functions before others in the pipeline (when they cannot behave alongside others), they need to reside in parentheses, which (as I understand it) appear to editors as "nests."

 

I do wonder if you made the nest larger than the native frame size, do you still face the quality issue when scaling?

I am sorry for the frustration; that's what's happening there. I think. All NLEs and mograph programs face similar issues with the render order pipeline.

 

Continue to file bug reports and feature requests. Some issues might be resolved by background operations or other engineering work.

 

I sure hope the team can fix your issues with this effects technique.

 

Thanks,
Kevin
