Shake reduction affecting side bars

[johnf83075185]

I have digitized 8mm cine films which import to Premiere Elements 2019 with black bars either side of the image.  When I try to use Shake Reduction it makes the edge between the image and the black bars noticeably unstable and wavy.  I imagine this would not be so noticeable if the image filled the screen.  I have tried various advanced settings but can't avoid this unwanted effect.  Can you suggest a way to overcome this?

The only solution I can think of is to enlarge your video so that it fills the frame side-to-side -- which means you're going to lose some of the top and/or bottom.

If you can see the edges of the video, you'll see the movement during shake reduction. That's just the nature of shake reduction.

Thanks Steve,

I want to avoid the clip I am adjusting looking different to the others around it and have found a solution which is a modification of what you suggest above.  First, zoom in slightly to reduce the width of the black bars.  Then apply the shake reduction (without crop).  Then zoom back out and using "FX: Transform: Crop", bring the bars back in to their normal width, hiding the wavy edge.  Thus there is minimal loss of image and the standard appearance is maintained.  I thought I would just share this with you and anyone else who may be interested.
