Ian Johnson maps Prelinger film dataset with UMAP and Marlin-2B vision latents

Ian Johnson used UMAP to visualize a video dataset, adding vision latents extracted from Marlin-2B for each clip alongside the included embeddings. He built the interactive map to render smoothly in the browser, with a writeup linked in the post. The quoted post by Daniel van Strien describes indexing 370 hours of Prelinger Archives films into 23,148 timestamped searchable moments.
