EffectCraft

Motion graphics and visual effects; an open-source, professional motion graphics and visual effects studio, built in pure Rust.

A free, open-source compositor: compositions, layers, keyframes, 306 effects, layer styles, expressions, 3D cameras and lights, and a render queue, native on macOS, Windows and Linux, and in the browser. Young, moving fast, and already usable.

What EffectCraft is

EffectCraft is for animated titles, motion graphics and compositing work: the kind of thing motion designers and VFX artists need. You build a composition out of layers (solids, shapes, text, footage, other compositions), animate their properties with keyframes, stack effects on them and render the result.

The interface feels natural and responsive, with dedicated panels (Project, Composition, Timeline, Layer, Footage, Effect Controls, Tools, Preview, Effects & Presets, Audio, Info, Paragraph, Character, Align, Progress, Render Queue) and standard motion graphics shortcuts, going further in a few places where it matters to us:

• Lottie import and export built in, so animations can go straight to the web and apps without a plugin.
• A project file you can read. Projects are versioned JSON (.ecproj), so they diff cleanly in version control.
• Everything is scriptable. Every menu item, timeline drag and property edit goes through one command registry, so the same actions are reachable from a command line, a JSON control channel and an MCP server for agents.
• No FFmpeg. Video and audio decoding and encoding are pure Rust: FilmCraft's codecs and EffectCraft's own VP9, AV1, HEVC and Opus encoders.

Animate

The panels, menus and shortcuts follow standard motion design conventions: Project, Composition, Timeline, Effect Controls, Properties, Effects & Presets, Character, Paragraph, Align, Info, Preview, Audio and the Render Queue, docked the way you expect. Drag footage, comps and effects between them: onto the comp viewer, where they land under the pointer, or into the Timeline, between layers and at the time you point to.

• Layers of every kind: solids, shapes, text, footage, nested compositions, nulls, adjustment layers, cameras and lights; parenting, track mattes, all 38 blend modes, motion blur.
• Keyframes that behave the same: linear, Bezier, hold, auto and continuous Bezier, roving keys, Easy Ease (F9), Keyframe Velocity and Interpolation dialogs, copy and paste at the current time, and a Graph Editor with value and speed graphs and draggable handles.
• Time: time remapping, time stretch, time-reverse, freeze frame, work area, markers, exact frame-accurate timing at every frame rate including 29.97 drop-frame.
• Shapes and masks: shape layers with trim paths, repeaters, round corners, offset, zig zag, twist, wiggle, merge paths and gradient strokes; masks drawn with the pen tool, with modes, feather, expansion and vertex editing in the viewer.
• Text: point and paragraph text with real shaping in any font installed on your machine, the Character and Paragraph panels, and text animators with range selectors.
• Expressions: JavaScript with the standard motion expressions model (wiggle, loopOut, thisComp.layer("…"), vector maths on arrays), an inline editor and the pick-whip.
• Timeline like you know it: twirl layers open to Transform, masks, effects and the rest; drag rows to reorder layers; rename with Enter or a double-click; the property shortcuts (A, P, S, R, T, M, F, E, L, U and their double presses AA, PP, SS, RR, TT, MM, FF, EE, LL, UU), Shift to add properties, Alt+Shift+A/P/S/R/T to key the current time, Ctrl+` to twirl selected layers.
• Puppet tools: Position, Advanced, Bend, Starch and Overlap pins on a mesh built from the layer, real-time pin recording, rotate/scale handles, pins driven by (or carrying) nulls for rigging, and follow-through for hair and cloth.

Effects

306 built-in effects across its categories, each with its parameter names, order and defaults: blur and sharpen, channel, color correction (Curves, Levels, Hue/Saturation, a full color-grading panel…), distort (Warp, Bulge, Turbulent Displace, CC Power Pin…), generate (Fractal Noise, Gradient Ramp, Stroke, Write-on, Audio Spectrum…), keying, matte, noise and grain, perspective, simulation (CC Particle World, CC Rainfall, Shatter, Card Dance, Caustics, Wave World…), stylize (Glow, CC Glass…), time (Echo, Posterize Time, Timewarp, Time Displacement…), audio (Reverb, Parametric EQ, Delay, Stereo Mixer…), text, transitions, utility and expression controls. All nine Layer Styles (Drop Shadow, Inner/Outer Glow, Bevel and Emboss, Satin, overlays, Stroke) with Global Light. Preview plays audio in sync, with meters and waveforms.

3D

Classic 3D compositing: 3D layers with orientation and material options, one- and two-node cameras with depth of field, lights (parallel, spot, point, ambient) with soft ray-traced shadows, layers that intersect correctly, orbit, pan and dolly camera tools, and Front, Top, Left and Custom views.

Export

A dedicated Render Queue, with Render Settings and Output Modules: H.264 MP4 and ProRes MOV (Proxy to 4444 XQ with alpha) with audio, HEVC (Main / Main 10) and AV1 MP4, WebM (VP9 with inter frames and alpha, or AV1; Opus audio), PNG, JPEG, TIFF and 32-bit EXR sequences, animated GIF and WAV/AIFF. Field rendering with 3:2 pulldown, effect/solo/guide/depth overrides, crop, region of interest and resize, Render Settings and Output Module templates with defaults, post-render actions, storage overflow and render logs. The same queue runs from the command line. Every encoder is pure Rust (FilmCraft's H.264, ProRes and AAC; EffectCraft's own VP9, AV1, HEVC and Opus); there is no FFmpeg inside.

Lottie goes both ways: File ▸ Export ▸ Lottie JSON… writes a composition (precomps, shape, solid, image, text and null layers, eased and spatial keyframes, masks, track mattes, blend modes, time remapping, optionally expressions) as .json or .lottie, and lists anything Lottie cannot express; File ▸ Import ▸ Lottie… opens one as a new composition.

Built for agents

Everything you can do from a menu is a command with an id, and agents can reach every one of them:

• MCP server: effectcraft-cli mcp speaks the Model Context Protocol over stdio, headless or bridged to the running app (--bridge 9877). Tools cover commands, the project and property tree, keyframes and rendered frames. This repository ships a ready .mcp.json.
• Command line: one-shot calls with JSON output, for example effectcraft-cli set Main '#1' transform/position '[100,360]' --time 0 main.ecproj --save or effectcraft-cli render --comp Main --out main.mp4, or effectcraft-cli exec file.exportLottie '{"comp":"Main","path":"main.json"}' main.ecproj.
• Control channel: effectcraft --control 9877 accepts JSON lines to run commands, inspect and click any widget by its automation id, and take screenshots.

See docs/agents.md and docs/control-protocol.md.

Where it stands

EffectCraft is young: its first commit was on 1 October 2026. A comprehensive feature set exists, including 306 effects, but breadth is not the same as full maturity across every edge case. Today it's a good place to try things and to tell us what breaks. It isn't yet recommended for production client work. In particular:

• Native project format. Projects are saved as .ecproj, readable versioned JSON. Proprietary project formats and After Effects SDK plug-ins are not supported.
• Fidelity is still being refined. Automated rendering tests currently focus on small compositions, so please report visual discrepancies or unexpected behaviour.
• macOS is the most tested platform. Linux and Windows users have hit basic interaction bugs, which we're fixing first.
• The trained models are new. Roto Brush can use MobileSAM (an optional 40 MB download in Settings ▸ Roto Brush) and face tracking can use Google's MediaPipe Face Landmarker (an optional 3.8 MB download in Settings ▸ Face Tracking). Both are actively undergoing evaluation and tuning.

EffectCraft is in alpha: about 91% of the features tracked in docs/target-app-parity.md exist, and we estimate it is about 45% of the way to being ready for full professional production work. The ROADMAP has the plan, docs/target-app-parity.md the measurement and docs/gaps.md every known shortfall. The web build (docs/web.md) runs the full app in the browser. Bug reports are the most useful thing you can send us right now.

How it's made

• Engine first. A stack of small crates with strict layering. The interface (egui) sits on top and nothing underneath depends on it.
• Clean room. We work from public documentation and observable behavior, never from proprietary files, icons, presets or code. No code is copied from GPL projects. The full rules are in AGENTS.md.
• Private by default. No telemetry, and no network access unless you ask for it.
• One family. EffectCraft shares its time model and text engine design with FilmCraft, and gets its video and audio codecs from it.

Want a specific build or format? On GitHub, the latest release has every build listed below, and all releases has earlier versions and their notes. <ver> in the file names is the version number, and SHA256SUMS.txt lists a checksum for every file.

Windows

Build	Installer	Portable
x64 (64-bit Intel/AMD)	effectcraft-<ver>-windows-x64.msi	effectcraft-<ver>-windows-x64-portable.zip

x86 (32-bit)	effectcraft-<ver>-windows-x86.msi	effectcraft-<ver>-windows-x86-portable.zip

Installers and executables are code-signed. The installer asks where to install EffectCraft (Program Files by default), and later versions install into the same folder. To install silently into a folder of your choice: msiexec /i effectcraft-<ver>-windows-x64.msi /qn INSTALLFOLDER="D:\Apps\EffectCraft".

RISC-V 64-bit: effectcraft-<ver>-linux-riscv64.tar.gz (tarball only; needs glibc 2.39+, e.g. Ubuntu 24.04+ or Debian 13+).

File drag-and-drop on Linux: The current eframe/winit 0.30 native Wayland backend does not deliver file-hover or file-drop events. On Hyprland and other native Wayland sessions, use File ▸ Import ▸ File… (which accepts multiple files), or start EffectCraft via XWayland if XWayland is installed and DISPLAY is set:

env -u WAYLAND_DISPLAY effectcraft

When the backend delivers events (X11/XWayland, Windows and macOS), dropping media anywhere in the window imports it, and a drop-target hint appears while hovering. On native Wayland the app cannot detect an attempt that generates no event; it shows a startup notice with the File ▸ Import fallback instead.
