thumbnail-extraction

What problem does it solve?

Manually scrubbing through long videos (interviews, presentations, Zoom recordings) to find engaging, high-quality frames for thumbnails is time-consuming and inefficient, especially when you need to capture expressive faces or key presentation slide moments.

Core Features & Use Cases

• Two-Pass Intelligent Scanning: Uses a fast OpenCV first pass to score frames for faces, smiles, and visual interest, then a DeepFace second pass to rank candidates by emotional engagement.
• Diverse Output Formats: Generates full-resolution JPG frames, cropped face images, and transparent background PNG cutouts ready for compositing, plus a metadata manifest with timestamps and scores.
• Temporal Diversity Guarantee: Ensures selected frames are spread across the full video duration, avoiding clustered picks from a single high-engagement segment.
• Use Case: A content creator processing a 1-hour conference talk recording can automatically extract 4 thumbnail candidates featuring expressive speaker faces and key slide moments in 2 minutes, instead of manually scrubbing the entire video.

Quick Start

Use the thumbnail-extraction skill to extract the 4 most engaging frames from your local video file 'conference_recording.mp4' and save them to your Downloads folder for thumbnail compositing.
