How fast are LLM inference engines anyway? — Charles Frye, Modal
Method
This deck is slide-only. The existing captured video frame set supplies candidate frames, then local OpenCV rejects sponsor/title/speaker-only frames, crops visible slide surfaces, deduplicates, and saves the cropped slide images.

- Recreated text/layout view: open HTML recreation
- AI slide classifier:
content_slideconfidence0.98 - Text source: none.
- OCR decision: ready — Dense product/UI screenshot with chart, small labels, and configuration text; OCR is better than manual transcription.
- Slide text: not surfaced (
illegibleby AI classifier).
