rotobrush is not working properly:
I start to select an object, and immediately after clicking the mask appears, no matter where I continue to brush the mask will not change, after I finish the mask just resets, what to do about it? watch the video.

Hi @NO314749244wyx,

Thank you for reporting this issue. Would you be able to share the project and footage with us? The behavior you are seeing may be related to the resolution or frame rate of the footage, but it is difficult to tell from the screen recording. Please also share your system specs.

Thanks again for reporting this issue and for any further information you can provide,
