First Rush (which I reported on last week) just got a major on-set update with live color + scopes, real-time compositing, a Companion Viewer that streams to iPhone/iPad with no router via P2P, and clip playback over SDI.
It’s also now available on the Mac App Store and is free to download.
If you are not familiar with First Rush, it is a native macOS multi-camera SDI recorder for professional film and broadcast workflows. It captures from Blackmagic DeckLink / UltraStudio and AJA hardware, records Apple ProRes MOV files, reads SMPTE RP 188 timecode and record flags, and prepares metadata for Final Cut Pro and DaVinci Resolve pipelines.
It was built by Jinkyu Han, a working on-set editor in the Korean film/TV industry. After years of fighting with Media Express and MovieRecorder on set, he decided to build his own macOS multi-camera SDI recorder.
Built for on-set assistant editors and DITs, it adds live color tools (ASC CDL wheels and LUTs), waveform, vectorscope, histogram and CIE chromaticity scopes, HDR monitoring, real-time chroma-key compositing, processed SDI program out, and a peer-to-peer companion viewer. Multi-camera grids, embedded audio metering, SDI diagnostics, camera HUD OCR fallback, slate naming presets, and reliable ProRes proxy recording — all native on Apple Silicon Macs.
A subscription is required to use First Rush. Monthly KRW 23,000 / Annual KRW 230,000, billed to your Apple Account at confirmation; auto-renews unless canceled at least 24 hours before the period ends, and can be managed or canceled in your App Store account settings. Requires Blackmagic/AJA SDI capture hardware.
