Segment Search — web interface

Interactive browser tool to rank movie/story segments by any combination of computational annotations and play the matching moment.

Launch

Serve from the project root with the bundled server, then open the page:

cd <project-root>
python3 tools/serve.py            # http://localhost:8000  (pass a port to change it)
# then open:  http://localhost:8000/analysis/web/index.html

Use tools/serve.py, not python -m http.server: the built-in server ignores HTTP Range requests, so <video> cannot seek — the scrub bar and “play segment” won’t jump. tools/serve.py adds byte-range support so seeking works. Serving from the root is also what lets the player load videos from /data/movies/...; opening index.html via file:// shows rankings but cannot play clips.

Use

• Filter/scroll the feature list (grouped by class); tick features to search on.
• Toggle each picked feature High / Low.
• Optionally filter by source and choose how many results to show.
• Segments are ranked by the mean z-score of the selected features. Each result has ▶ Segment (seeks to its start, auto-stops at its end) and ▶ Clip (plays the whole stimulus); the player repeats these for the loaded segment.
• Selected features are plotted as a time series over the whole clip, with a marker that tracks playback. Click the plot to jump the video to that time; the video scrub bar works too.

Rebuild the index

segments.json is generated from the annotated corpus. Regenerate after annotating more stimuli (or to change the window length):

PYTHONPATH=src .venv/bin/python tools/build_search_index.py --seglen 5
