Caveats

• State lifetimeStabilisation is stateful across frames: it holds the previous frame and a rolling window of warps inside the running container, so a feed that pauses or resets is steadied relative to whatever frame preceded it.
• Parameter interactionsmoothing_radius sets how many frames the warp is averaged over; larger values are smoother but lag real camera moves, smaller values track faster but leave more residual shake.
• Parameter interactionA higher-order motion_model corrects more distortion but needs more reliable keypoints, and motion estimation that fails for a frame falls back to no correction for that frame rather than erroring.
• I/O contractWith crop_borders on, the warp-revealed margins are cropped and the valid region is rescaled to the original size; with it off, full size is kept with black fill. Output dimensions always match the input either way.
• LimitationContent shaken out of frame cannot be recovered, and strong rolling-shutter skew is not corrected since the model is a single global warp per frame.
• State lifetimeAll configuration is captured once at startup; changing any setting requires a redeploy.
