Fusion tab resets/overrides scale/position

Not sure if this is a 'Fusion' issue, or a 'Fusion in Resolve' issue.

I have a clip that needs to be stabilized and scaled to fill the frame. It's 2048x1536 going into a 1080p sequence. It can be scaled and positioned fine in the normal editing tab, but once I do anything in the Fusion tab, that seems to get ignored and it pops back to being scaled to fit and centered in the display. It also acquires some sort of hard matte where I can move it around and resize it with the normal transform controls, but it has hard bars locked to the ratio of the original scaled-to-fit image.

I'm attaching three images. One the original scaled and positioned frame. One how it pops back after it's been tracked and one zoomed in to show the hard matte that's coming from somewhere.

Still getting used to fusion-in-resolve. It's a much nicer workflow, but there's some oddities.

Thanks for any insights anyone has.

Giving this a bump to see if anyone has any ideas. Would this be better posted in the Fusion forum?

It's hard to tell what's going on from the pictures. What are you doing to the image in Fusion? Maybe post some images of that? My guess is that you're doing something in Resolve that comes after Fusion in the image processing pipeline order of operations. Probably stabilization, but I haven't played with resolve stabilization in combination with Fusion, so I couldn't tell you for sure. Normally, color page effects with the exception of OFX plugins happen *After* Fusion processing. I'm pretty sure resolve's stabilization counts as a color page effect. See page 786 of the user manual.

Try turning the clip into a compound clip to force color page effects to happen before fusion.

The only thing I'm doing in fusion is adding a tracking node for stabilization. I agree that it's an order of operation issue of some sort, I'm just not sure what to do about it. Assuming that using the Fusion tab overrides the position and scale settings from the edit tab, how would I then go about sending back a version that is sized and positioned the way I want?

Not something I have run into before doing this kind of thing because I've done round-trip renders of tracked footage from Fusion, but I'm hoping to avoid that in this case.

I'm hoping someone else has run into this. With all the re-framing that happens this won't be a unique problem.

So I've played around some more. It looks like if your source is a different aspect ratio than your sequence and you are doing anything to it in the Fusion tab, you need a crop node in Fusion to match the aspect ratio/resolution of the project/sequence. Otherwise you get some really odd behaviors. Hope this helps anyone who runs into similar issues.
