Flickering (Green/Yellow) Despite Clean Feature Points
Hello, to help you understand more quickly, I’m attaching a zoomed-in view of one of the points. (This is not an occluded point — it’s a clean feature that remains visible throughout the entire footage.)
I created a sufficient number of tracker points using User Tracks and proceeded with the tracking. I also set the focal length and sensor size to match the original footage. (The tracking itself worked well.)
However, I have a question. Many of the tracking points flicker between green and yellow, and when I inspect those points, I notice that some sections are partially missing or empty.
Even when I try to fix this manually using the Adjust function, it doesn’t seem to resolve the issue.
What could be the cause of this, and is there a recommended solution?
Hello thanks for providing the screenshots.
It appears that trimming is enabled, which is why you’re seeing gaps in the Scrub Bar. These gaps correspond to the spikes for that particular tracker in the Residual Errors graph; those frames fall outside the trim line and are therefore ignored during the solve. Either delete or adjust your trim line then use Adjust to fix or disable any trackers with high residual error and run Refine All again.
For further information on residual errors and trimming trackers, please consult the documentation here
Regarding the “flickering green and yellow”, I’m assuming you’re referring to the tracker colours in the Cinema view after solving/refining. Any rapid flickering in the residual error may be caused by compression artefacts in the footage.
