Dancing Edges of Scaled Photos

PostTue Mar 23, 2021 10:08 pm

Hi all,

I'm trying to do a simple image scale that you can see in 00:07 of the video below. It's a 4000x6000 photo that the photographer wanted to show the full vertical crop of. So I did your typical full-screen + blur of the photo in the background to make it work for widescreen. When I did the image upscale animation (just scale keyframes in the edit page), the edges of the photo were dancing / alias-ing like crazy. I ended up saving that image at 65% the size in Photoshop, then in Resolve cropping in on the edges, and then softening them a bit too...It's not really ideal, and there is still a tiny bit of dancing with that approach. Is there any way to have Resolve read high res imagery correct?

Alternatively, I'd be happy to do this simple comp. in Fusion if I could just figure out how to work in a 1080p composition with these 4000x6000 photos...Whenever I add them as my Media In, the composition becomes the size of the photos..

Any tips at all on how to do this without making sacrifices or just going to Premiere would be great...Thanks!

It can be done with the OFX Blanking Fill.

You need to create a transparent background node in fusion and merge the photo with it. This way your composition will be at 1080p

Interesting...Yeah with all sliders in the Fill Appearance down to zero, and the cropping on the Source down to zero it seems to give a similar effect. I actually like this more as it zooms as if it has a track matter over it, vs actually zooming the entire image. Thanks.
