Question

Roto Brush propagating every frame in CC2020

Hi all,

I've been running into this really frustrating behaviour with the roto brush recently.

Basically I can only do one or two actions before the entire timeline re-propagates. It used to be that it would only propagate the frames after the stroke keyframe (in the direction of propagation), allowing you to iterate along the timeline easily. This current behaviour is unworkably slow. Any idea why it's doing this?

ADOBE -

instead of eight tracking features/methods with sub-par performance...

how about ONE tracking feature with ok or even just predictable performance!?

 

I mean, you're not designing a version of a douchey guy that can fake his way through a bunch of first dates - ya know by seeming to know a little about a lot of different things... having the information not cuz the subject is important to him, but becuz it might just get him  laid? ..... wait . sh*t.. you sort of are doing that. aren't you??

      This was happening to me and I realized one of my layers accidentally had the fx turned on. When I turned it off, it stopped propogating.

        How do you take the FX off of your layer?

          I beleive there is a known bug that still hasn't been fixed. Regardless, I think your footage would still be problematic and not necessarily propagate more favorably. Perhaps you might want to explore methods liek tracking masks - with or without mocha.

          Oh it's propagating fine - just very, very tediously.

           

          Is it a project by project bug? I've never seen it before.

           

           

          The mocha track isn't going great as the reason I'm having to mask these windows out is they're extremely reflective. The tracker gets all kinds of confused.

          You don't need to mask every window in Mocha, you just have to grab one of the corners, then add another spline to the layer and grab another corner or two, then run the track.

           

          If this were my shot this is how I would set up a track for the building:

          This will give you a clean track of the building very quickly.

          If the goal is to separate the building from the background then a second simple spline linked to the track (layer 1) can be created in just a few minutes. 

           

          I don't know what your design goals are but Rotobrush would be my last choice for creating a matte for anything I see in this shot.
