Are these the actual slides from the talk?

Yes. Video2Any read the published recording and kept one image per slide change. FOSDEM publishes its 2021 recordings under CC BY 2.0 BE, which permits reuse with credit; we credit FOSDEM and link to the original file above.

Do diagram-heavy research slides work as well as text ones?

They work the same way, because the detector compares pictures rather than reading them. What matters is that the slide changed and then held still, which a diagram does exactly as a bullet list does.

Can I do this with a conference talk I recorded?

Yes, and it is free for your own files. Drop the recording in and Video2Any detects each slide, keeps one clean frame per change, and exports an .pptx or PDF — in your browser, with nothing uploaded.

Albert Yumol presented this research in the Open Research Tools and Technologies devroom at FOSDEM 2021: using OpenStreetMap street networks as a proxy for socio-economic indicators, by way of network theory and the OSMnx Python package. Video2Any stepped through the 15-minute recording and kept 28 clean frames, one per slide change. A research talk is a good test of the extractor, because the slides are dense with diagrams rather than bullet points, and a network graph that renders in stages is exactly the sort of thing a strict reading would split into several slides. Every image below is real output, extracted in a browser tab with nothing uploaded.
