Key, roto, paint and track.
Comp is independent compositing software for everyone. Work with layered EXRs, OpenColorIO, local AI and camera projections.
Windows · macOS · Linux
Built-in tools
Keying, roto,
tracking and 3D.
63 built-in nodes for compositing, from plate preparation to the final render.
Keying and edge treatment
Pull a matte, remove spill and recover foreground color at soft edges with MultiKeyer, apDespill, BlendSpill and EdgeReconstruct.
Roto and paint
Animate splines, adjust feathering and paint or clone out unwanted details. Track shape motion while keeping manual corrections editable.
Tracking and matchmove
Track points and planar surfaces. Stabilize footage or export CornerPin animation for screen replacements.
Lenses and warps
Undistort a plate, composite the insert and reapply distortion. Import supported 3DE lens exports or use built-in models.
Color and channels
Read EXR layers and AOVs, route channels and apply Grade, HueCorrect or OCIO transforms. Pick HDR colors in working space.
Camera projections and 3D
Project footage onto cards, import camera animation and render depth, UV, motion-vector and per-object alpha passes.
Graph and content browser
Browse sequences and AOVs from Input. Batch-import folders and organize the graph with backdrops, thumbnails and Dots.
Local AI tools
Segment subjects with SAM3, refine mattes with MatAnyone2 and key green screens with CCkey, based on Corridor Crew Keyer 1.
Smart caching
Reuse cached node results when revisiting frames. Lossless cache compression keeps more frames in memory.
Comp 0.2 beta
New since
Comp 0.1.2.
Comp 0.2 brings a redesigned interface, a rebuilt Color Picker and content browsing directly from Input.
Organize graphs with backdrops and keep more frames in memory with lossless cache compression.

Does Comp support OFX effects?
OFX effects are not supported in this build.
Is compositing GPU accelerated?
Image processing runs on the CPU. The Viewer uses the GPU for display when available; local AI uses a supported accelerator.
Can I import a Nuke project?
General Nuke project and gizmo import are not supported. LensDistortion can read supported 3DE lens data from Nuke-format exports.
