Video Object Rotoscoping, Tracking & Inpainting via Meta Open-Source SAM 2 & ComfyUI

End the nightmare of manual frame-by-frame rotoscoping! Meta's open-source Segment Anything Model 2 (SAM 2) brings zero-shot mask segmentation to continuous video. Click any moving object in frame 0—an actor, a jacket, a vehicle—and SAM 2 tracks it across hundreds of frames through occlusions. Integrated with ComfyUI, creators can achieve automated video inpainting, wardrobe swaps, and dynamic background replacement.

CORE TOOLS SAM 2 (Meta Open Source), ComfyUI, PyTorch, OpenCV
BEST FOR VFX artists, video editors, fashion e-commerce designers, commercial directors, virtual production creators
REQUIREMENTS CUDA-enabled PC with 8GB-16GB VRAM (RTX 3060/4060 or better), compatible with Windows and Linux.
✦ WHY THIS WORKFLOW

Manual video rotoscoping traditionally demanded days of painstaking bezier curve adjustment by post-production artists. SAM 2 transforms rotoscoping into a single click, delivering one of the most staggering productivity upgrades in computer vision.

READY-TO-USE PROMPT TEMPLATE
Open Official Tool / Repo ↗ 
I am using Meta's open-source SAM 2 inside ComfyUI for video wardrobe replacement and object inpainting.
Please provide:
1) [Occlusion & Tracking Correction Protocol]: Keyframing positive and negative guidance clicks when subjects turn around or pass behind obstacles to maintain unbroken tracking;
2) [Flicker-Free Temporal Mask Smoothing Nodes]: Node chain configuration (Mask Dilate, Gaussian Blur, Temporal Smoothing) eliminating jagged edge flutter during frame-by-frame diffusion;
3) [Headless Python Batch Script]: Python script using SAM 2 API taking an MP4 and initial coordinate to output transparent ProRes 4444 alpha matte videos directly.
Use Cases & Tags:
