Lightweight Motion Editor

FlashFX runs entirely in the browser. There is no download, no installer, no licence manager and no per-machine setup. Opening the editor URL is the whole process, and the same projects are available from any machine you sign in on.

It runs in Chrome, Edge, Firefox, Safari, Brave and Opera. Rendering uses WebGL, so a browser with hardware acceleration enabled will perform noticeably better than one without.

FlashFX Lite is a further-reduced editor for quick edits and simple animations. It keeps the core object types and animation model while dropping the heavier parts of the full editor, which makes it faster to load and lighter to run.

The Lite documentation covers its interface, the object types it supports, gestures, animation, export, and — importantly — its limitations, so you can tell in advance whether a piece of work fits inside it.

Browser-based rendering has real constraints, and a few habits keep projects responsive:

• •Keep the working canvas at the size you actually need. A 4K canvas quadruples per-frame rendering cost against 1080p.
• •Blur and glow effects are among the most expensive per pixel — stack them sparingly.
• •Large imported images cost memory whether or not they are scaled down on canvas.
• •Enable hardware acceleration in your browser settings.
• •Keep the number of simultaneous 3D elements low; each one runs its own renderer.

The GPU constraints section of the editor documentation covers the rendering environment, memory management and profiling in detail.
