![]() Performances: Never wait for anything to be rendered, in Natron anything you do produces real-time feedback thanks to its optimized multi-threaded rendering pipeline and its support for proxy rendering.It is possible to separate on any number of screens the graphical user interface. Intuitive user interface: Natron aims not to break habits by providing an intuitive and familiar user interface.OpenFX samples (in the Support and Examples directories).OpenFX-Yadif deinterlacer : An open-source efficient de-interlacer.OpenFX-OpenCV : A set of plugins based on OpenCV.OpenFX-Arena : A set of extra nodes (bundled with the pre-compiled versions of Natron).OpenFX-Misc : A set of basic nodes, such as Transform, chroma keyer, etc… (bundled with the pre-compiled versions of Natron).OpenFX-IO : to read anything else than standard 8-bits images (bundled with pre-compiled versions of Natron).Support for many free and open-source OpenFX plugins:.Dozens of file formats supported: EXR, DPX, TIFF, PSD, SVG, RAW, JPG, PNG … and more.Colorspace management handled by OpenColorIO.32 bits floating point linear color processing pipeline.Run the output from your camera into a Mac, then click on your background and it will disappear, revealing the movie or still image of your choice. How do you shoot a complex green-screen scene when all you see is an actor against a big green wall? Chroma Key Live makes it simple again. (Assuming you could afford the expensive studio or at least a video mixer.) Now chroma key effects are included in every editor, but they can’t be easily visualized during production. ![]() This way, the production team could see exactly how the actor looked when composited over the background image. The camera’s live signal would be routed through a keyer in the control room and delivered back to an on-set monitor. ![]() In the days of analog video, chromakey was accomplished in the TV studio in realtime. The keyed output is published as a Syphon stream for other applications to use. Movie playback can be controlled from the keyboard for easy cueing and rehearsal. (See the Camera Compatibility page for complete info.) The foreground and background layers can be independently scaled, positioned, and mirrored (so your actors don’t see themselves backwards). The foreground / background sources include FaceTime cameras, USB webcams, HDMI capture cards, Syphon streams, and pre-recorded movies or stills. CamTwist Studio has a chromakey feature, but it’s buried pretty deep.)Ĭhroma Key Live performs a basic realtime chromakey (AKA “greenscreen”) on your computer screen, in HD resolutions, with adjustable tolerance and edge fade. (There are other free solutions: OBS Studio has a chromakey filter built-in. We didn’t need the advanced features of professional software like Veescope, Wirecast, MimoLive or VirtualEyez so I made my own solution. It features Syphon I/O, HD resolutions and full GPU acceleration.Ī few years ago, some of my students were doing a green-screen shoot and needed to visualize the chromakey while shooting, so their actors could see the composite while they performed. Chroma Key Live “keys out” selected areas of live video, allowing a background to show through.
