Garbage Mask for Stabilizer?

PostFri Jun 05, 2020 11:12 am

Is any way possible to mask out person from videoclip when using stabilization on edit/color page?
It's normal practice to remove moving objects with mask in Premiere or AE before stabilization, but i can't find how to do it Resolve.

Thanks!

I question that. To what end?

Maybe to that end that if you want to stabilize camera movement you have to exclude moving objects because they have different motion paths... Same practice as if doing matchmove etc.

I know that some stabilization process allow the editor to choose the point(s) to use for solving, but I've never heard of anyone 'removing' an object from the frame to improve that solve. Especially since a proper removal in a moving frame would need some kind of solve first, wouldn't it?

I did some experimenting with this. What might work is first do any masking on the clip with cropping or whatever, then make it a compound clip. Stabilize this compound clip then copy the stabilization data to the clipboard. Go back and decompose the clip and remove the masking, then paste the data back to the stabilizer.

not sure if there is an interactive way to add/remove tracking points... might be in the classic stabilizer....

There is a way to delete tracking points in the classic stabilizer. It might be something to at least check out.

You don't actually need to remove object but rather tell the solver to not spawn any autotracks to that area. Usually manually rotoing a garbage matte is the way to do it.

Thanks for the video, but in new resolve there are no such options as interactive mode or top option to select what axis you want to select.

Resolve will only get you so far. For advanced work get Mocha.

You're GENIUS! Great idea, works terrific! SHAME what BMD didn't implement masks to exclude moving objects while stabilizing. You can exclude moving objects only in classic method but it works TERRIBLE. Anyway, Prodad Mercalli works way better... And it's a shame too that Mercalli OFX still not working in Resolve :(
