Long lecture recordings are a strange format.
The useful part is often not the video itself. It is the slide deck trapped inside the video: a lecture, webinar, product walkthrough, Zoom recording, or screen share where the presenter spends most of the time on mostly-static slides.
So I built Video2Any, a browser-based tool that turns videos and screen recordings into PowerPoint decks, PDFs, image frames, and subtitles. The unusual part is that the video does not need to be uploaded. The browser does the decoding, slide detection, and export locally.
On my tests, an hour-long lecture-style video can usually be sampled in under a minute on a normal laptop. The exact speed depends on the video, browser, codec, resolution, and device, but the important design choice is this: the tool does not need to understand every pixel of every frame at full resolution.
It only needs to answer one question quickly:
