RotoBrush 2 Selection Expansion issue

Whenever I try to use Rotobrush 2, the selection constantly expands after a few frames until it selects the whoel screen.



I tried 4 different videos and reinstalled After Effects, but it behaves the same as well.

 

Furthermore, it also sometimes yield the error message : Unkown Exception too.

Any help on why this tool is behaving this way would help a lot.

Hey again, just a small update: I formatted and reinstalled a clean Windows 10, graphic drivers I knew worked before and After Effects 17.6. The problem remains. I have however noticed that other applications (high end games mainly) are crashing more and After Effects is now acting strange in general; sluggish, viewport slow to render, freezing up etc. I'm guessing hardware issues and probably not AE related. I'm also guessing that the machine learning algoritm in Rotobrush 2.0 is using the GPU (while 1.0 probably uses CPU?) and so the problem probably lies within my GPU. Will try to run AE with only integrated motherboard graphics and see what happens!


Updating here for anyone googling the same issue. Managed to solve it by underclocking my RTX 2070 through the Aorus Engine app. So basically reduced the clock speed a bit and that solved all of my problems. Buying a new graphics card anyway since obviously something must have degraded in the card - just ran it on default clock values before.

Hey, I have the exact same issue. Have used Rotobrush 2.0 a lot but suddenly it's expanding in that weird way.

Have tried: Resetting preferences, rolling back to previous AE versions, rolling back graphics drivers, different kinds of footage etc. Have noticed the "Best" quality setting starts expanding earlier than "Standard".

Specs:

Windows 10 (v1903)

After Effects 17.6

Intel 9900k 3.60ghz

Geforce RTX 2070

64gb ram

 

Did you find any solution to this? Any help is appreciated. Thanks!

Hi @martinf15146508,

I'm sorry to hear that you're also experiencing this issue. We still have not been able to reproduce this problem in-house, even with the details from @Yeow Kiat Chia above. From the specs you posted ( thank you for those ), I don't see much in common between your specs and the others who are experiencing this same issue.

 

Was Roto Brush 2.0 working for you prior to installing After Effects 17.6? But now those previous versions are not working even after rolling back to previous AE versions?

 

Thank you for any additional information,

Thanks for the response, John!

 

Yes 2.0 was working great, have used it extensively. I can't be 100% sure that it was the 17.6 update that introduced this (it could've been graphic drivers update etc) but since installing it Rotobrush 2.0 has been like this. I've tried rolling back to all versions dating back to when 2.0 was introduced and always with this same result.

 

Should I do a clean reinstall of After Effects? Been trying to avoid that (lots of plugins, extensions to reinstall) but don't see another solution.

 

Thank you so much for the help!

Hi Yeow Kiat Chia,

Thank you for reporting this issue, and sorry to see this is happening when you use Roto Brush 2. Since this is occuring with multiple videos, it seems like there may be either a system incompatiblity or a bug in how Roto Brush is processing propagated frames.

  • What are your system specs? Operating system version, hardware, RAM, GPU, etc.
  • What were the resolutions of the various videos you have tried? Does a smaller resolution video exhibit the same problem?

 

Thanks very much for any additional information you can provide as we attempt to diagnose what is happening.

I have the same thing happening, it switches from what I have Rotobrushed to full Frame Selection.

Hi @mw21146471,

Sorry to see that you are experiencing this issue as well. Please post your system specs, perhaps there will something in common between your system and @Yeow Kiat Chia's which could be a potential cause. Also, take a look at the steps for log collection that I've outlined below. If you are able to, please submit those logs and screen recording to rotobeta@adobe.com

 

Thank you for reporting this issue and for using After Effects (Beta),
