# Dense Slides: Evals 101 — Doug Guthrie, Braintrust

## Source Video
[Evals 101 — Doug Guthrie, Braintrust](https://www.youtube.com/watch?v=bk0TmxoZlUY)

## 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.

## Cropped Visible Slides
