Collect and label scenes
Extract keyframes from representative videos and create an evaluation set with scene-level annotations or text captions for retrieval testing.
Index video scenes. Assess retrieval accuracy.
Video scene indexing organises video into searchable segments by extracting representative frames, embedding visual (and optionally audio/text) content, and storing vectors for nearest-neighbour search. Key failure cases include poor keyframe selection, heavy domain shift between training and production footage, and noisy or misaligned multimodal signals.

Video scene indexing organises video into searchable segments by extracting representative frames, embedding visual (and optionally audio/text) content, and storing vectors for nearest-neighbour search. Key failure cases include poor keyframe selection, heavy domain shift between training and production footage, and noisy or misaligned multimodal signals.
A possible application: let archive staff find scenes by example images or short text queries to speed cataloguing. In any production use a human reviewer to confirm matches before archival decisions are made; this starter does not deliver a production-ready retrieval system.
Extract keyframes from representative videos and create an evaluation set with scene-level annotations or text captions for retrieval testing.
Embed frames (and optional subtitles) with a pretrained visual or multimodal model such as CLIP, keeping train/validation splits to avoid leakage.
Store vectors in a nearest-neighbour index (FAISS) and measure retrieval metrics like Recall@K and mean reciprocal rank on held-out queries.
Measure latency, failure modes (false positives/negatives), and design a review UI that lets humans inspect and correct results.
The supplied starter loads the sklearn digits dataset, splits it, fits a RandomForestClassifier, prints a classification report and shows a confusion matrix. It does not process video frames, compute image or multimodal embeddings, nor perform retrieval or indexing.
model = RandomForestClassifier(n_estimators=300, random_state=42)
model.fit(X_train, y_train)
predictions = model.predict(X_test)
print(PROJECT_NAME)
print(classification_report(y_test, predictions))
The starter uses the handwritten-digits dataset and a RandomForest classifier; this does not implement scene extraction, embedding, vector indexing or multimodal retrieval described by the project title. Results on digits do not validate video indexing or search behaviour, and there is no evaluation of Recall@K, grounding, latency or human-usefulness metrics.
A proposed extension: extract keyframes from videos, embed them with a multimodal model (e.g. CLIP), store embeddings in a FAISS index, and expose a simple web UI for example-image and text queries with human verification.
This is a potential application pathway, not a delivered product. The supplied starter does not implement this service or validate it with real users.
