ComfyUI Video Stabilizer

Two complementary stabiliser nodes for ComfyUI:

| Node | ID | Highlights | | --- | --- | --- | | Video Stabilizer (Classic) | VideoStabilizerClassic | Feature tracking + Gaussian-smoothed affine/perspective motion. Fast, CPU friendly. | | Video Stabilizer (Flow) | VideoStabilizerFlow | Dense DIS optical flow with global motion smoothing. Higher quality, heavier compute. |

Classic Node (VideoStabilizerClassic)

• Motion models: translation, similarity, or perspective.
• Gaussian trajectory smoothing (smoothness 0.0?1.0) with adaptive crop budget (stabilize_zoom).
• Framing control via CROP (max common crop) or CROP_and_PAD (minimal crop plus padding colour).
• Per-frame binary masks for downstream inpainting/compositing.
• Deterministic CPU pipeline (OpenCV + NumPy).

Flow Node (VideoStabilizerFlow)

• Dense optical flow via OpenCV DIS with adaptive downsampling for speed/robustness.
• Motion models: translation, similarity, or perspective with bundle smoothing.
• Adaptive zoom allowance and framing options (CROP / CROP_and_PAD).
• Deterministic CPU pipeline that outputs binary missing-area masks aligned with the stabilized frames.
