Task Overview

Your task as an annotator is to watch each video in the dataset and label it according to the appropriate dance style. The videos have been downloaded from YouTube and their original titles have been obfuscated, so your job is to carefully observe the dance movements and assign the correct label.

Labeling Rules

🔴 You will be "labeling" videos by dragging the video file from the root directory within /videos_for_annotation/ into one of the sub-folders for each dance style. Example: ballet_labeled, jazz_labeled, etc..🔴

  1. Watch at least 30 seconds of each video before making a decision.
  2. If the dance style is clear from the start, you may move the video earlier, but ensure you have enough context.
  3. In case of uncertainty, watch up to 1 minute to finalize your label.
  4. Drag and drop the file to the appropriate dance style folder.
  5. If the video does not fit into any of the predefined categories, you can place it into the "other_labaled" folder.
  6. Avoid using prior knowledge of the dance style based on assumptions or prior familiarity; the label should be based solely on the video content.
  7. Make sure your labels are consistent across all videos you annotate.

Examples

  • Ballet: Example of correct labeling—video shows structured movements like pirouettes, pointed toes, and graceful arm gestures.

    • Incorrect label: Hip-hop (because the video focuses on structured ballet techniques rather than freestyle movements).
  • Hip-Hop: Example of correct labeling—video shows freestyle dance with rhythmic body pops, lock and break movements.

    • Incorrect label: Breakdance (because while hip-hop often includes similar movements, breakdance focuses on acrobatic, floor-based moves).
