Node-based compositing, reimagined.

Settings inside the node

Double-click a node and its settings open right there in the graph, with every control the Properties panel has. You can work without a Properties panel at all.

Every channel is a socket

Expand a node to get a socket for R, G, B, A and for every layer of your EXR. Wire a single pass straight where it's needed, with no Shuffle. A Cryptomatte is one socket.

Wire first, pick the node after

Drag a wire into empty space and the node picker opens; the node you choose arrives already connected. Drag a wire from one input to another to move it, or to swap two inputs.

Vertical or horizontal

Build your tree top to bottom or left to right. Your choice is remembered.

Trackers that do the job

Stabilize, Match Move and CornerPinTracker track and move the picture in one node: no Export, no second node to wire. Track repair fills gaps in a track and works out a hidden corner from the other three. Stabilize and Match Move take as many track pairs as a shot needs, so when one leaves the frame another takes over, and tracks can extrapolate past their last frame.

Roto and paint, redesigned

• A remove brush that paints objects out with texture from around them: no clone source to set
• Each roto point animates on its own, not the whole shape
• Bezier tool with alignment guides and typed offsets
• Dodge and burn limited to shadows, midtones or highlights
• Permanent black and white swatches: Shift+X switches them
• A master offset moves every stroke at once, keyed or linked to a tracker, with Keep Transform and a tweak on top

SVG and vector graphics

Drop Illustrator or Affinity SVG files into the comp, layer order kept. The Vector Graphics node draws lines and shapes with fills, outlines, dashes, gradients, masks, filters and text, all editable and animatable.

An AI that shares your undo

The built-in MCP server lets Claude, or any other MCP client, build and edit the comp you have open. Its changes go into your undo history. More below.

Any language

Node names and notes in any script, with spaces and punctuation, and a Text node that shapes every script correctly. See it below.

FocalFinder

Draw vanishing lines on a still and get a matching camera, ready for projections.

Camera tracker guides

Draw a few lines along a building's edges or a kerb and the camera solve keeps them, through the lens it solves: the scene comes out square to your shot, ready for a cube that fits. Draw the same edge when the camera comes back round a room and the drift closes.

Live link with Blender

Model, light and animate in Blender and watch the scene update in JOS as you work. Lights, cameras and moves you set in JOS show up in Blender, and undo works on both sides.

Blender's best nodes

Kuwahara, Pixelate, Despeckle, MaskToSDF, DoubleEdgeMask, plus Voronoi, Wave and Brick textures.

Keying included

Our own Screen Keyer, IBK, ChromaKeyer and Despill, alongside Keyer and HueKeyer. No third-party keyer licence needed. Nuke scripts keyed with IBK or Keylight come in keying like Nuke: measured on real green-screen shots, on motion blur and fine hair.

Sliders inside the number fields

Drag any number field to change its value, and hold Shift to move ten times slower for fine adjustments. Click to type a value instead. Blender users will feel right at home. 😉

Set up for your machine

A hardware test measures your CPU, memory, GPU and disk, then fills in the cache, GPU and tile settings for you.

Industry Standard compatibility

Open .nk scripts and gizmos: the tree is rebuilt using JOS nodes with their corresponding settings, and gizmos become Nests.

A node graph that feels familiar

Fast gestures and keyboard shortcuts for every common move.

• Tab node picker with fuzzy search
• Ctrl+F finds nodes by name and frames them
• Branches that can't render (a missing file, an unknown node) shown in red, with the reason
• Drop a node on a wire to insert it, shake it to pull it out
• Clones, linked nodes, Backdrops, a minimap, per-node render times
• Dockable panels and workspaces

Colour managed with OpenColorIO

Every colour conversion goes through OCIO, with the ACES configs built in or any config file, chosen per project. Processing is float and scene-referred: values are never clamped behind your back, and viewer settings never alter your images.

Every channel, every pass

Images carry any number of named channels. Multilayer and multi-part EXRs keep every pass, and each one can be wired on its own without a Shuffle.

• Cryptomatte, with a picker in the viewer
• Deep compositing: DeepRead, DeepMerge, DeepHoldout, DeepRecolor and more

Roto and paint

Roto shapes (Bezier, ellipse, rectangle, and open splines: strokes with a width per point) with feather and motion blur, animated point by point. Paint with brush, eraser, clone, reveal, remove, blur, smear, and dodge and burn. Curves and strokes stay editable: the pixels are always derived from them. Auto Path Tracking makes a shape follow a subject that bends and moves, forward, backward and between your corrections.

Tracking

Point tracking for stabilizing and match-moving, CornerPin2D, a planar tracker, and a camera tracker.

Keying, warping, time

• ScreenKeyer, IBKColour and IBKGizmo, Keyer, ChromaKeyer, HueKeyer, Despill
• SplineWarp, GridWarp, IDistort, STMap
• OpticalFlow, Retime, TimeWarp, motion vectors, VectorBlur
• Defocus, ZDefocus, Glow, Grain, Denoise, Text

Fast where it counts

Only what you look at is computed: the visible region and the viewed layer, at the viewer's zoom level.

• Tiled rendering
• RAM, disk and GPU caches, proxy levels, prefetch for playback
• Vulkan GPU processing for Grade, Merge, Blur, Transform and the maths nodes

3D on USD

A 3D viewport, cameras, lights, cards and primitives, MaterialX/OpenPBR materials and projections, built on USD and Hydra. Point clouds, Gaussian splats and VDB volumes come in too.

Animation and expressions

Every parameter can be keyed, from sliders to checkboxes. Includes a curve editor with a toolbar, a pivot to scale keys about any frame and Blender-style keys, a dope sheet, expressions and linked parameters.

Nests and Precomps

Group nodes into a Nest with its own inputs, outputs and exposed parameters. Double-click to go inside, or nest a selection with Ctrl+G.

Fits your pipeline

• OpenFX plugins, with Natron's free set (about 500 effects) a click away
• Python 3.13 with PySide6, a script editor and plugin menus
• Optional plugins for Autodesk Flow Production Tracking and Kitsu
• jos-render for render farms, with no UI
• A path manager, with path mappings between Windows and Linux

Formats

OpenEXR, PNG, JPEG, TIFF and WebP in and out, as files or sequences. Movies in and out as MOV, MP4 or MKV: Apple ProRes (422, 422 HQ, 4444), H.264, H.265 and FFV1. iPhone footage opens as shot. .braw camera files in, with their decode settings (JOS Compositor compatible with Blackmagic Design Blackmagic RAW). Audio with waveforms on the timeline.
