MultiRec records up to 8 SDI and NDI sources at once, each to its own file and locked to one shared master timecode. Built for live production, where reliability matters.
Features
These features come from years of experience in live production, each one shaped by what we've learned on real shows.
Mix Blackmagic DeckLink SDI and NDI sources. Each one records to its own file from its own encoder process, so trouble on one feed can't touch the others.
Every file carries the same master timecode, so your clips line up the moment they hit the timeline. If a frame is dropped, MultiRec fills it instead of shortening the clip, so sync never drifts over a long take.
A watchdog restarts any encoder that crashes or hangs. Files stay playable even after a power loss mid-take, so a single failure never costs you the whole recording.
ProRes runs on the CPU; H.265 and H.264 run on the GPU through NVENC. Set the codec and quality per input, and mix CPU and GPU feeds in the same session to spread the load.
Up to 16 channels of embedded PCM audio, lossless and muxed straight into the file, in sync with picture.
Set the color metadata per file: primaries, transfer (gamma), matrix and range. Footage lands in the grade tagged correctly, not guessed at.
Up- or down-scale and convert frame rate per input. Normalize all feeds to one rate and resolution so timecode and sync hold across every clip.
Lay out feeds, clocks and overlays, then send a full-screen multiview to a second display.
Per-channel audio meters, a pre-flight go/no-go check before you arm, and a report after every recording telling you exactly what happened.
Inside the app
System requirements
ProRes encodes on the CPU, so simultaneous ProRes feeds scale with core count. H.264/H.265 encode on the GPU via NVENC, freeing the CPU. Here's what each reference build comfortably handles.
All capacities below are for 1080p50. 4K/UHD is much heavier. Size up a tier, or run fewer simultaneous feeds.

Perpetual licenses
A perpetual license, locked to one machine. Every tier has the same features, and you're only choosing how many inputs you record at once. Updates within the major version are free, and the unlicensed demo includes everything too, capped at 10 minutes a recording.
MultiRec is in final pre-release. Drop your email and we’ll tell you when it’s out, plus the founding price.
