Engineered for Motion Designers
Everything you need in one WebGPU pipeline. Keyframing, 2.5D cameras, lights, vector tools, and skeletal rigging.
Cameras, lights and depth
Make any layer 3D to gain Z position and X/Y rotation. One- and two-node cameras with depth of field, lights with cone angle and shadows, extrusion and bevels for shapes and text. Grab a camera or a light in an orthographic view and move it, parent it to a null, and animate from there.
Keyframes on any numeric property
Linear, ease, ease-in, ease-out, hold and custom bezier. The graph editor edits value and velocity curves directly, and position keeps X and Y as independent tracks so they can be eased separately.
Cameras, lights and depth
Make any layer 3D to gain Z position and X/Y rotation. One- and two-node cameras with depth of field, lights with cone angle and shadows, extrusion and bevels for shapes and text. Grab a camera or a light in an orthographic view and move it, parent it to a null, and animate from there.
Per-glyph text animators
A real selector stack: animate position, scale, rotation, opacity, tracking or colour across characters, words or lines, with range and wiggly selectors. Text on a path included.
Bones and puppet pins on flat artwork
The bone tool builds a skeleton with forward kinematics, linear blend skinning and FABRIK IK. The puppet tool deforms a triangulated mesh from pins with an as-rigid-as-possible solver.
Paths that behave
Pen, pencil, pressure-sensitive brush and curvature tools. Boolean merges, trim paths, pucker/bloat, twist, zig-zag, repeaters, dashed and tapered strokes.
A deterministic emitter
Rate, lifetime, velocity, gravity, turbulence, size and colour over life. The same field always produces the same field, so a re-render is identical to the first one.
Unified Timeline Engine
Every panel edits the same document model with instant undo/redo history.
Compose Engine:Multiple compositions per project, each with its own size, frame rate, duration and background. Nest one inside another as a pre-comp with time remapping, and instance it more than once. A placed composition is sealed - it renders at its own size, through its own camera - until you collapse transformations and let it meet the host’s.
Natural Language Keyframing
Describe the motion prompt to keyframe values or offset tracks. Every action applies as a single reversible edit.
“Stagger the five cards in from the left, 4 frames apart, easing out.”
Deterministic Frame Rendering
One WebGPU frame loop feeds every format. Frame index divided by FPS ensures identical exports every single time.
The default for sharing. Needs ffmpeg.
Smaller than MP4, plays on the web.
Lossless hand-off. Large. Needs ffmpeg.
Palettised across the animation. No audio.
The archival option. Audio rides along.
Vector shapes and transform tracks.
Deterministic by construction
One frame loop feeds every format, and frame time is index / fps rather than wall-clock. Re-render after a crash and you resume identical work.
It refuses to write an empty file
Every path asserts on a real frame count. A zero-frame encode is an error, not a silently successful black video.
Peak memory is one frame
Frames go to a temp directory and ffmpeg encodes in a child process. A multi-gigabyte export never passes through the app's memory.
Preview the actual export
The export dialog renders real export frames with the same snapshot builder the encoder receives, and lets you scrub the whole range first.
After Effects Muscle Memory
Maps directly to familiar shortcuts, tools, blend modes, track mattes, and pre-compositions.
- All 17 blend modes, track and alpha mattes, parenting and adjustment layers
- Classic-3D layer model: flat planes in 3D space, lit and shadowed
- Keyframe assistants - easy ease, time-reverse, sequence layers, stagger
- Expression controls: slider, angle, point, colour, checkbox, dropdown, layer
- Collapse Transformations and Continuous Rasterization, on the same sunburst column
- Interpret Footage: conform frame rate, pixel aspect, alpha, loop - stored on the asset
- Proxies, generated or attached, substituted in the viewport and never in output

Open-Source Core, Optional Hosting
Run the full desktop studio locally for free. Cloud plans add synced projects and remote rendering.
Self-hosted
The whole editor on your own machine, under the AGPL.
Download- Every tool — compositions, graph editor, 2.5D, rigging, particles
- No account, no network — projects are .motion bundles on disk
- Export to every format, offline, with no watermark
- The AI assistant with your own provider key
- AGPL-3.0 source — read it, build it, fork it
The assistant needs the desktop app and an OS keystore to hold your key. Everything else runs anywhere the app does.

Free and open to everyone during the beta. Paid plans are coming soon at $12/month; your projects will always export back to the free build.
Frequently Asked Questions
Everything you need to know about Premation Studio, WebGPU rendering, licensing, and After Effects project compatibility.
It is used in earnest, but it is pre-1.0 - version 0.1.0. Expect rough edges, and expect the project file format to still move. Around 5,400 automated tests across roughly 470 suites cover the app and its engine packages, alongside a pixel-comparison render-test harness with committed reference frames.

System Requirement Notice
Premation renders every frame on the GPU via WebGPU or WebGL2 fallback. A hardware graphics processor is required.
