Notes on Video2Any: what it does, how we think about speed and privacy, and where it is going. It runs in this tab — no upload, no account, no watermark.
What changed this month
Undo and redo, a preview that takes the room when you need it, the deck following the video, the frames you added marked as yours, and a dozen smaller fixes.
A Chrome extension that reads your lecture without downloading it
Click the icon on a recorded lecture and its slides open in the next tab. What crosses between the two halves is a few megabytes of still frames, never the recording — and that limit is the design, not a shortcut.
Convert a whole course in one run
Point Video2Any at a folder of lecture recordings and get a deck for each one, in the right order, with nothing uploaded. Step by step, including what batch mode will not do.
0.2.0: what a webcam bubble does to slide detection
Four real runs turned a video into 900 slides — one per sample, nothing rejected. The open detector behind Video2Any now masks the part of the frame that never holds still, and picks its own threshold. With the numbers.
Decoding video in parallel, in a tab
No upload means no server, which means a browser tab has to demux MP4 by hand, run four decoders at once, and still stay usable. What that costs, and the stack around it.
Which export format should you pick?
One extraction, nine files. What PowerPoint, Word, Markdown, a contact sheet and a bare audio track are each actually good at — and why there is no MP3.
Eight bugs that looked like the algorithm
A week of debugging a browser video pipeline. Two were in the detector. The rest were a stale guard, a lying test harness, a virtualised list, and an error message that threw away the useful half of itself.
Your video-to-PowerPoint export has 300 slides. Here’s how to get 40.
Builds, laser pointers, webcam overlays and fades each split one real slide into a dozen frames. Tuning the detection beats deleting them by hand.
NotebookLM video to PPT or PDF: two honest ways to get the file
NotebookLM can export a newly generated Slide Deck itself. If you need the exact visuals from an existing Video Overview, convert that downloaded video instead.
Turn a lecture recording into notes, not just slides
The slides are only half of it. Here’s how to get the slides and the spoken words as notes you can actually study from.
How to extract PowerPoint slides from a lecture video
The professor never shared the deck, but every slide is right there in the recording. Here is how to get them back as a PPTX, step by step.
How to recover slides from a Zoom recording
The presenter shared their screen, the meeting ended, and the deck never arrived. The recording has every slide — here is how to get them out.
Why video-to-PowerPoint tools miss slides (and how to test the output)
Sampling, thresholds, transitions, motion, and deduplication fail in different ways. Here is how to identify the stage that went wrong.
What “editable PPTX” actually means: image slides, OCR layers, and native objects
Image slides, OCR text layers, native PowerPoint objects, and AI-generated decks are four different outputs. Here is how to inspect the file.

What to look for in a video-to-PPT converter, and the honest case for Video2Any when you want slides rather than an embedded clip.
WebM in PowerPoint: why it won't play, and how to fix it

Your video never leaves your browser
Privacy here does not depend on a promise. Conversion happens on your machine, so there is nothing to upload, nothing to store, and nothing to leak.
