What changed in October: builds folded, a pages slider, and why
This round changed how a deck gets cleaned up after detection, which is where most of the time in Video2Any goes. Below is what changed, and — because most of it came from watching how the editor was actually used — why we built it the way we did.
One idea runs through all of it: missing a slide costs you more than deleting one. A frame you do not need takes a keystroke to remove. A slide that was never captured means going back to the recording, finding the moment and capturing it by hand. So detection now leans towards keeping more, and the editor got better at folding away and stepping through the extra.
The short version
- A slide that is built up line by line now shows as one card — the finished slide — instead of five near-copies.
- A Pages slider replaces Sparse / Default / Dense. It changes the count instantly, without reading the video again.
- Moving the slider towards Fewer drops the briefest frames first, so a slide that stayed on screen is the last thing to go.
- Review shows one slide at a time beside the video: arrow keys to move, X to delete, Z to undo.
- Ignore an area tells detection to look past a clock, a ticker or a webcam corner.
- A Guide button walks you through the editor, and an example recording lets you try all of it without a file of your own.
Slide builds fold into one card
What you’ll see. When a slide appears line by line — bullets one at a time, a diagram filled in, a terminal that keeps printing — the editor now stacks those frames into a single card showing the finished slide. A small number on the card says how many frames are inside; tap it to see them or split them back out. Split all undoes it for the whole deck.
Why. The people who cleaned up the most by hand were almost all deleting the same thing: one slide caught several times on its way to being finished. We had a "select similar" button for duplicates, but it looked for similar pictures anywhere in the deck, and on builds it usually found nothing useful — so we removed it. The new check is narrower and safer: it only compares neighbours, and it only folds a frame into the next one when the next one still contains everything the first one showed. If anything disappeared — an annotation wiped, a page cleared — they stay apart, because then nothing is lost only if you keep both. We tested it on lectures with a speaker inset, whiteboard recordings, terminal-heavy meetings and animated explainers before turning it on. The known weak spot is burned-in subtitles that change sentence at the same moment a title appears.
A Pages slider instead of three presets
What you’ll see. Sparse, Default and Dense are gone. In their place is one slider from Fewer to More, with the count shown next to it. Dragging it updates the deck right away: the video was already read once, so choosing a different number of pages is a fresh selection from what was read, not a new pass over the file. The default sits towards More.
Why. Three presets made you guess which word matched your recording, and changing your mind meant waiting for the video to be read again — so people mostly turned it up to Dense and then deleted by hand. A slider with a live count answers the question you actually have ("how many pages is this?") and costs nothing to try. The default leans towards more slides for the reason at the top of this post: deleting is cheap, recapturing is not.
Fewer pages now drops the briefest frames first
What you’ll see. When you move the slider towards Fewer, the editor keeps the same number of pages as before, but chooses differently which ones. Frames that were on screen only briefly — a transition, a few seconds of a live demo — go first. A slide someone talked over for half a minute goes last.
Why. We found this while comparing converters on a public conference talk — the full comparison is linked at the end of this post. At the default setting Video2Any found all 19 slides. But with the slider moved down to 25 pages, it had dropped the last three slides of the deck — each on screen for half a minute or more — while keeping several frames from a one-minute software demo. The cause: "fewer" used to mean "only count bigger changes", and a slide that differs from the previous one by a line of text is a small change, while a demo repaints most of the screen. How long a picture stayed on screen turns out to be a much better sign of whether it was a slide. On the same talk, the same 25 pages now hold 18 of the 19 slides instead of 15; the default result did not change at all.
Review, one slide at a time
What you’ll see. Review opens the current deck one slide at a time, large, next to the video at that moment. Use the arrow keys (or swipe) to move, X to delete, Z to undo, Esc to leave. Every change is the same as making it in the grid, so undo and export see it too.
Why. Checking a deck in a grid of thumbnails means squinting at small pictures and clicking around. The real question for each frame is simple — keep or not — and it is fastest to answer with the slide large and the video beside it. Keyboard first, because once your hands are on the keys you can get through a long lecture in a few minutes.
Ignore an area
What you’ll see. Under detection settings, Ignore an area lets you draw up to four boxes over the video — a clock, a stock ticker, a chat panel, a webcam corner. Detection then runs again without looking there. Nothing is ignored until you draw something.
Why. A part of the screen that is always moving makes every frame look new, so a still slide gets captured over and over. We already mask a speaker inset automatically when it is easy to find, but some things are not, and you can see them at a glance. We kept it off by default on purpose: guessing wrong would hide a real slide change, and that is the mistake we least want to make.
A guide, and an example to try it on
What you’ll see. The Guide button at the top of the editor walks through the controls in the order you would use them, pointing at each one with a short example. No video at hand? Try an example — on the home page and in the editor — opens a short lecture-style recording we made for the purpose, with a slide build, a speaker inset and a few pages, so every control has something to do. On a phone, the guide now unfolds the detection settings first, so it can point at the controls inside them.
Why. New controls are only useful if people find them, and a help page nobody opens does not do that. The example exists because the fastest way to understand what the editor does is to watch it work on something, and not everyone arrives with a recording in hand.
What we took out
Select similar
Replaced by folded builds, which handle the case it was meant for without you having to pick anything.
The "too many slides" notice
After a run, the editor used to warn when a recording produced a lot of slides for its length and offer to show fewer. A count alone cannot tell an over-detected deck from a recording that really does change that often, and the slider is right there if you want fewer. So the warning is gone.
Smaller fixes
Export on some Android phones
Extraction could finish and export still fail, because re-capturing the frames at full size did not work in that browser. Export now falls back to the frames already extracted instead of failing.
Matroska files
Some .mkv files were refused even though the browser could decode them; the file is now read directly before giving up.
Signing in
Email sign-in is a single code step, and coming back to the tab keeps you on it instead of starting over.
Questions
Do I need to re-extract my old decks?
No. Decks you saved before keep their slides, and builds are folded when you open them. On an older deck, the slider may read the video again the first time you move it.
Can folding hide a slide I need?
A frame is only folded into the next one when the next one still contains everything it showed, so the card always has the content of every frame inside it. If you want the steps themselves, tap the number on the card, or use Split all.
Why does the default give more slides than before?
Because a missing slide is harder to fix than an extra one. Drag the slider towards Fewer if you want a shorter deck; it updates instantly and drops the briefest frames first.
Is anything uploaded?
No. All of this runs in your browser on your own device; the video is not uploaded.
