""" description_p = """# Interactive Video Segmentation - Built our demo based on [SAM2-Video-Predictor](https://huggingface.co/spaces/fffiloni/SAM2-Video-Predictor). Thanks to Sylvain Filoni. - Instruction
  1. Upload one video or click one example video
  2. Click 'include' point type, select the object to segment and track
  3. Click 'exclude' point type (optional), select the area you want to avoid segmenting and tracking
  4. Click the 'Segment' button, obtain the mask of the first frame
  5. Click the 'coarse' level and the 'Track' button, segment and track the object every 15 frames
  6. Click the corresponding frame to add points on the object for mask refining (optional)
  7. Click the 'fine' level and the 'Track' button, obtain masklet and masked video
  8. Click the 'Reset' button to restart
