Built for Apple Silicon Macs.
An Apple Silicon Mac on macOS 15 or later is all InterDirector needs to run. Some inputs, outputs and controls need a little more, and it is listed here.
What you need.
- Mac
- An Apple Silicon Mac
- macOS
- macOS 15 or later
- Video
- NDI sources on your network, network streams over RTMP, SRT or RTSP, USB capture that appears to macOS as a camera, Blackmagic devices with Desktop Video installed, or windows of your other apps
- Audio
- Any Core Audio device; native Apple Silicon VST3 effects are optional
Only if you use them
- Blackmagic
- Blackmagic Desktop Video, installed from Blackmagic, for Blackmagic inputs and output.
- NDI HX
- The NDI HX driver from NDI, for NDI HX sources. Ordinary NDI needs nothing extra, and InterDirector shows a message if a source needs the driver and it is missing.
- Stream Deck
- Stream Deck software 6.4 or later, to use the Stream Deck plug-in that comes with InterDirector.
- VST3
- VST3 effect plug-ins built for Apple Silicon. Instruments are not supported.
Questions people ask.
Is InterDirector a vMix alternative?
vMix is Windows software. InterDirector is a native Mac app that covers the parts of that workflow a Mac operator needs: NDI-based switching, audio, graphics, streaming, recording and replay. It is not a clone, it does not open vMix projects, and as one developer's app it does not do everything vMix does. How it compares with vMix and four others.
What does it cost?
It is free to try for 14 days on each Mac, with everything unlocked and no card needed. Then a licence is €40 a month, or €100 every 3 months, VAT included, covers two Macs, and renews until you cancel, which you can do any time. Buy a licence.
Which Macs and which macOS?
Apple Silicon Macs running macOS 15 or later. Intel Macs are not supported.
What capture hardware does it support?
NDI sources on your network, USB capture that macOS exposes as a camera (a capture card such as the Elgato Cam Link is one example), and Blackmagic capture devices through Blackmagic's Desktop Video software.
Can I use my VST3 plug-ins?
Yes: Apple Silicon native VST3 effects, on sources and on buses. Instruments are not supported.
How does it get updates?
InterDirector checks for signed updates the moment it starts and every hour while it is open, and installs one only when you say. It never checks while you are streaming, recording or sending NDI.
What video formats can a Show run at?
A Show runs at 720p, 1080p, 1440p or 2160p, at 24, 25, 29.97, 30, 50, 59.94 or 60 frames per second. Video is progressive, standard dynamic range, Rec. 709.
Where do I stream to?
To RTMP, RTMPS and SRT destinations, several at once, from a single encode, in H.264 or HEVC. Program can also go full screen to any display macOS detects, leave as NDI and out of a Blackmagic device.
Can I record?
Yes. Program records to a QuickTime file with HEVC, H.264 or ProRes video and 24-bit sound, written in one-second fragments so that a crash keeps nearly everything. Armed NDI, network stream, USB, Blackmagic, audio and Window inputs can also be recorded to their own files.
Does it work with Stream Deck?
Yes. The plug-in comes with InterDirector and needs Stream Deck software 6.4 or later. Its keys light up to show state.
What happens if a camera or a network source drops?
InterDirector keeps trying to bring it back, at intervals that stretch to thirty seconds, and its card says it is retrying. Your other sources, and the outputs, carry on.
Does it send anything about my show anywhere?
No, unless you send us an issue report from Help → Report an Issue…, which lists what it carries before you send it. Otherwise the journal and diagnostics that InterDirector keeps stay on your Mac.
Can I make my own overlays?
Yes. An overlay is an HTML package with a small description of the controls it offers, so anyone who can write a web page can make one. Twenty-five overlays come with the app.
