landmark stability on video frames

Hi, is there a way to stabilize the landmarks for subsequent video frames? The landmarks move quite a bit, even when there is no face movement in the video. They "jump around" by ~10 pixel.
Where does this behavior come from?

The issue is about landmark jitter in video frames. Start by looking at the video processing pipeline, likely in the main inference module. Check if there is temporal smoothing or tracking logic. Run the library on a sample video to observe the jitter. 'Done' means proposing a stabilization method, which requires understanding the model's frame-by-frame predictions.
