(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. You're right it's very likely too early to switch full time, but like with any other major transition (say you'd like to switch to Windows instead) I'd base my decision on actual compatibility reports from vendors/other users, or purchase a device for a test drive and return it if it's not cutting it.Chroma Key Live “keys out” selected areas of live video, allowing a background to show through.
Of course if you pitch it against a maxed out Mac Pro in a multicore benchmark, its gonna get blown off the table but it already beats it (and almost everything else on the market) at single core also almost every multicore benchmark I've seen says it's out-classing everything in its price range and even quite a bit beyond it.
I'm curious where were you reading about things being extra slow on M1. In case of NDI, they also already have a native ARM implementation for iOS, so I'd expect official support to come sooner than later. For the rest, usually a recompile is enough, unless you've done some pretty silly assumptions (like pointer size, when going 32->64bit), in which case your software was likely in a bad shape to begin with.
NDI falls into this category, but still, the binary translator does not care how the software was written - it translates machine code into machine code. You don't need to rewrite the software either, unless you wrote some parts in x86-64 assembly (which of course, certain performance-sensitive applications need). The visible differences are mostly due to clock speeds. In fact, millions of developers do: on iOS, raspberry pi, AWS graviton, and so on. I write software every day on an x86-64 box and then test it and run it in production on ARM boxes. You don't need to redesign your software to run it on a different CPU architecture, or to take advantage of its performance (or performance per watt). You're right that it's likely too early, but most of your statements are quite inaccurate.
