Browser-based Video Editor (Website)

Design webfrontendwasmgraphics Tooscut

Tooscut is a professional browser-based video editor leveraging WebGPU and Rust/WASM to achieve near-native performance for editing and real-time previews.

What: Tooscut offers a non-linear editing (NLE) experience directly in the browser, featuring GPU-accelerated compositing, keyframe animation, and multi-track timelines, all without installation, utilizing WebGPU and Rust/WASM.

Why it matters: This project demonstrates the increasing capability of web technologies (WebGPU, WASM, File System Access API) to deliver complex, performance-intensive applications previously confined to native desktop environments, pushing the boundaries of what's possible in the browser.

Takeaway: Explore WebGPU and WebAssembly with Rust if you need to build high-performance, complex multimedia applications for the web.

Deep dive

Tooscut is a professional, browser-based non-linear video editor.
It offers GPU-accelerated rendering and compositing using WebGPU and Rust/WASM.
Features include multi-track timeline, keyframe animation with bezier easing, and real-time GPU-computed effects (brightness, contrast, blur).
The editor provides near-native performance for real-time previews and exports.
No installation is required; the application runs entirely in the browser.
Media stays local on the user's machine, utilizing the File System Access API.
The project highlights the potential for complex applications to run efficiently on the web platform.

Decoder

WebGPU: A new web standard API that provides access to a computer's graphics processing unit (GPU) for rendering and compute operations, offering more powerful and lower-level control than WebGL.
Rust/WASM: Refers to using the Rust programming language to compile code into WebAssembly (WASM), allowing near-native performance for computationally intensive tasks in web browsers.
Non-Linear Editor (NLE): A video editing system that allows for non-destructive editing of video and audio in any order, common in professional video production.
File System Access API: A browser API that allows web applications to read and write files and directories on the user's local system after user permission, enabling local-first functionality.

Original article

Professional video editing, right in your browser

A powerful NLE editor with GPU compositing, keyframe animation, and real-time preview. No installs required.

Everything you need to edit

Built on WebGPU and Rust/WASM for performance that rivals native apps.

GPU-Accelerated Rendering

WebGPU-powered compositing via Rust/WASM delivers near-native performance for real-time previews and exports.

Multi-Track Timeline

Canvas-rendered timeline with unlimited video and audio tracks, linked clips, and cross-transitions.

Keyframe Animation

Animate any property with bezier easing curves. Transform, opacity, effects — everything is keyframeable.

Real-Time Effects

Apply brightness, contrast, saturation, blur, and hue rotation — all GPU-computed with instant preview.

Zero Install, Full Power

Everything runs in the browser. Your media stays local with the File System Access API — nothing leaves your machine.
