Stroke effect resizes image upon export

I applied the “Stroke” effect to some still images to add a white border. Then I added scale keyframes to make the image move. Looks great in the timeline, but when I export, the still images (and sometimes the images beneath them) are a drastically different scale, so they get knocked outside the frame.

From reading similar bug reports, it’s possible this has something to do with GPU acceleration? Unfortunately I’m on a Mac Studio M1 Max, so it doesn’t look like I can disable GPU acceleration. 

 

Edit: Gaussian Blur effect is causing the same problem. Workaround is to reset all Motion effects (Position, Scale) and recreate those effects using the Transform effect instead. This fixed the problem.

      Hi ​@kevina41766135 

      Welcome to the Premiere forums! We’re glad you’re here. I see you’re using an M1 Max, could we also get a few more details with Important Details for an Adobe Bug Report? I’m glad that you discovered a workaround by using the Transform effect to fix it. I believe for that Mac if it’s like this one, attaching screenshot, it’ll be grayed out and can’t be changed that way.

        @kevina41766135 I agree, and they should match! I should have clarified better in my response that this is what I’d found so far that did confirm your workaround with Transform and possibly why that was working for this, but that I was still. investigating further. Sorry for all your frustration dealing with this.

        Would there be any way you can capture a little screen recording of the timeline/media encoder previews and what it actually exports? You can DM me either a link to that or I can provide one to our Dropbox, whatever is easiest for you.

        Also, when you’re scaling, can I clarify because on the Effects Control Panel, there’s that built-in Motion > Scale. Then, if you apply the Stroke effect for another example, it has a tick box under “PreTransform” to apply Prescale, in which you can also set keyframes for Scale, and then there’s the addition if adding Transform effect which also has Scale as well.  

        I believe you first tried Motion Scale, and after the render/export mismatch, tried using Transform from the Effects panel for scale, correct? But, did you also apply any PreTransform/scale from Stroke, as you can keyframe that too? 

        Appreciate your patience very much,
        Katie

        Maybe it’s not the Stroke effect. I have a still image with no effects added except Gaussian Blur, and that is giving me the same problem - it looks correct playing in the timeline, then when I export it totally resizes. If I disable the Gaussian Blur effect, it exports correctly.
