VMAC is the first native macOS live production switcher with instant replay — built from scratch on Metal for Apple Silicon. Multi-camera switching, pro audio mixing, and sports replay without a Windows VM.
Every other Mac "switcher" is a ported Windows app or an Electron wrapper. VMAC is native Swift and Metal — the way broadcast software should work on a Mac.
Zero-copy Metal rendering
Built from scratch on Metal with CVMetalTextureCache. No Electron, no OBS fork — just raw Apple Silicon performance with industry-leading latency. Cut, fade, and transition between unlimited sources with tally and multiview.
Sports-grade instant replay
vMix-style replay workflow with one-tap marks, variable-speed playback, and multi-angle switching. Mark key moments with a single key, then replay them in slow motion from any angle. Built for sports production.
Multi-camera + NDI input
Local cameras, USB capture cards, NDI sources — all auto-discovered. Record every angle simultaneously in ProRes with hardware encoding. Up to 4K resolution with zero-frame-drop ingest.
SRT + RTMP output
Stream to YouTube, Twitch, Facebook, or any custom endpoint. SRT with adaptive bitrate and packet loss recovery. Up to 4 independent outputs running simultaneously with per-destination encoding settings.
Broadcast-grade mixer
Per-source channel strips with 4-band parametric EQ, compressor, limiter, and gain control. Audio-follows-video routing with real-time metering. Submix buses, aux sends, and master output processing.
HTML5 overlay engine
Overlays, lower thirds, scoreboards, and stingers powered by a built-in Chromium renderer with zero-copy IOSurface compositing. Use any web technology to design your broadcast graphics.
Built for IP-based production workflows
VMAC natively supports NDI and OMT for both input and output — no adapters, no plugins, no workarounds. Discover sources on your network automatically, route video between machines, and build distributed production setups that scale.
Combined with SRT and RTMP streaming, VMAC connects to anything on your network or across the internet. Send program output to multiple destinations simultaneously with independent encoding settings per output.
Plug in your cameras. VMAC does the rest.
Plug in cameras or add NDI streams. VMAC auto-detects inputs and starts recording every angle in ProRes.
Cut between cameras live. Mark key moments with a single key, then replay them in slow motion from any angle.
Output via SRT, RTMP, or NDI. Record in ProRes, H.264, or HEVC. Up to 4 independent outputs at once.
Core is free forever with full 4K production tools. Upgrade to Pro to unlock advanced streaming, multi-output, and more.
