Release notes
Every improvement, fix, and new feature — documented as it ships.
May 27, 2026
OneshotFX can now automatically transcribe your speech into captions and generate studio-quality narration — all processed locally on your device.
Finish a recording and OneshotFX extracts your mic audio, runs Whisper via Transformers.js right inside the editor, and drops generated captions straight onto your timeline. No cloud, no waiting for uploads — it all happens on-device.
Turn any caption into polished voiceover. Pick a friendly voice — Miles, Ava, and more — and OneshotFX generates narration audio that plays during preview and is baked into your export. Narration can replace your original mic speech while keeping system audio intact.
One click wipes timeline captions, generated narration state, cached STT captions, and related TTS cache — a clean slate without hunting through individual segments.
OneshotFX now tracks STT transcription count, duration, caption blocks, TTS generation count, character count, and narration duration. TTS cache hits aren't counted as new generations, so you won't burn through limits unnecessarily.
Captions now use word-level timestamps and smarter grouping into natural blocks, with improved start/end padding so text appears and disappears at the right moment.
Longer recordings are transcribed in chunks for accuracy. The engine falls back from WebGPU to WASM automatically when needed, and you can cancel auto-caption generation at any time.
Friendly loading messages during STT/TTS processing, human voice names like Miles and Ava, and a cleaner captions list with per-caption play/refresh buttons removed for narration entries.
Per-recording artifact manifests, centralized artifact deletion, TTS cache ownership by recording ID, and size/LRU-aware cache cleanup. Deleting a recording also cleans related TTS cache entries, and legacy unowned entries are handled safely.
The Include Audio export toggle now correctly suppresses generated narration as well. STT, TTS, and export workers are properly bundled in production builds so packaged extensions work out of the box.

OneshotFX is now available in 9 new languages, and you can add customizable captions to your recordings with six different styles.
OneshotFX now speaks your language. German, Spanish, French, Hindi, Japanese, Korean, Portuguese, Russian, and Simplified Chinese are all supported. The extension automatically uses whichever language your browser is set to.
Add text to any moment in your recording. Pick from six styles — pill, outline, box, neon glow, typewriter, or a label that follows your click position. You can adjust the font, color, size, and whether it sits at the top, center, or bottom of the frame.
Skip the boring parts or slow things down for impact. Drag a speed segment onto your timeline to fast-forward through repetitive sections or add slow-motion to highlight key moments. Everything is applied automatically when you export.
Element highlights whatever you clicked with a colored overlay, and Element Spotlight dims everything else to draw the viewer's eye straight to it. Both are great for tutorials and demos where you want your clicks to be unmissable.
The Settings panel now shows your current quality and time limit right at the top, so you can double-check everything before you start recording without hunting through the options.
March 25, 2026
Webcam support lands with full picture-in-picture overlay, the Property Panel gets a ground-up redesign, and you now have fine-grained control over audio in your exports.
You can now record your webcam alongside your screen. Select your camera device, preview the feed before you start, grant permissions right from the popup, and position the overlay exactly where you want it. The webcam footage is automatically merged into your final exported video — no extra steps needed.
Get a moment to prepare before OneshotFX starts capturing. Choose a 0, 3, or 5-second countdown from the recording settings.
Choose whether to include or strip audio from your exported file. You can also mute playback while editing in the editor without affecting the final export.
The Property Panel has been rebuilt from scratch for a cleaner, more intuitive editing experience. Zoom segment settings and keyframe controls are now easier to find and faster to adjust.
March 3, 2026
This is the first public beta release of OneshotFX.
You can now pin the camera to a specific spot on the video, independent of where your cursor was. Enable Focus Point in the Zoom Segment properties, click Pick on canvas to place it, or fine-tune with the X / Y sliders.
Auto-Zoom now reacts to keyboard activity, not just mouse clicks. The camera stays zoomed in while you type and pulls back when you stop — making walkthroughs that mix typing and clicking look much more natural.
Click animation rings were showing up offset from the actual click when Zoom inside window was enabled. This is now fixed.
If you already had browser tabs open when you installed OneshotFX, click tracking and the instruction modal weren't working until you refreshed those tabs. Both now work correctly from the very first recording — no refresh needed.
Several under-the-hood improvements to the editor's rendering pipeline make playback noticeably smoother, especially on longer recordings with lots of click events.
Adding, moving, resizing, and deleting Zoom, Crop, and Skip Segments are all fully undoable with Ctrl/Cmd + Z.
Added a Zoom mode toggle to choose between zooming inside the window or scaling the whole window. Shadows and rounded corners also render more smoothly.
OneshotFX is in public beta. All features are free during this period.
