Projects and saving
Autosave, keeping several projects, working offline and installing as an app.
4 min
In most editors the first thing you learn is Ctrl+S. There's no such key here, because there's no need for one: your work saves itself. Every cut, every slider move is written into your browser's storage a few hundred milliseconds later. Close the tab by accident, lose power — when you come back, it's all still there.
But this kind of saving is not quite like the kind you're used to, and it's worth understanding the difference — otherwise, one day, you may lose your work.
How autosave works
Your work is split in two and stored in two different places. It's a technical detail, but it explains why the studio opens as fast as it does.
Media files → OPFS
The video and audio files themselves. OPFS is a private file system inside the browser: it can hold heavy files — even gigabytes of video.
The project itself → IndexedDB
The timeline, tracks, cuts, effects — the “recipe”, in other words. It's tiny, which is why it can be rewritten after every single edit.
WHERE your work lives
This is the most important paragraph in the guide. Your project lives in this browser, on this computer. Not on a server, not in a cloud, not in your account — there is no account.
- Open it on another computer and your project isn't there.
- Open it in another browser (Firefox instead of Chrome) and your project isn't there.
- Clear the site data in your browser settings, or wipe “everything” — and your project is gone for good.
Several projects at once
You can keep as many projects on the go as you like — working on one never touches another.
“New project”
Choose it from the top menu. Your current project is NOT deleted — it's saved first and stays in the list. The new one simply opens alongside it.
Pick a size
When you create the project you click a platform preset (the list is below). You can change the size later, but getting it right up front saves work: change the aspect ratio and you have to re-position your layers.
The “Projects” list
This is where all your projects sit. Click one — the current one is saved and that one opens. Renaming and deleting happen here too.
YouTube — 16:9 (1920×1080)
The classic landscape frame — for desktop and TV screens.
TikTok / Reels / Shorts — 9:16 (1080×1920)
The vertical frame that fills a phone screen edge to edge.
Instagram — 1:1 and 4:5
Square (1080×1080) and the slightly tall post (1080×1350) — they take up more room in the feed.
Light — 720p (1280×720)
The same 16:9, but with half the pixels. The kindest option on a slower machine, and great for quick tests.
Installing it as an app, and working offline
Ondo Studio is a PWA: a web page that can nevertheless be installed like an ordinary app. An install icon appears in the address bar of Chrome or Edge (or use “Install” in the menu). Click it and the studio opens in its own window, without browser chrome, and shows up among your applications.
Once installed it opens without an internet connection: since all the editing happens on your machine, no network is needed to work at all. On a plane, on a train, when the internet drops — you just carry on.
Theme and language
The studio comes in a dark and a light theme. Dark is the default, and not by accident: against a dark background you judge the colors in the frame more honestly, and your eyes tire less over a long session. If you're working in a bright room, switch to light.
The interface speaks Uzbek or English, switchable from the language picker. Your choice is remembered. It only affects the interface: your project, your file names and the text inside your video are untouched.
Common questions
How do I move my project to another computer?
For now, only by exporting the finished video. There's no way yet to carry the project itself — timeline and all — around as a file.
It says a media file could not be found.
The browser may have cleared its storage (when the disk filled up, or because of a cleanup setting). You'll have to import that file again.
Can I work in a private/incognito window?
It runs, but everything vanishes the moment you close the window — that's the whole point of incognito. For real work, use a normal window.
Won't the storage fill up?
Video takes up room. Delete the projects you no longer need from the “Projects” list — their media files are freed along with them.
