Broadcast-ready recording software

Record every angle.
Never lose a take.

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.

For Windows 10 & 11 · 64-bit

Features

Built to keep rolling

These features come from years of experience in live production, each one shaped by what we've learned on real shows.

Up to 8 inputs

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.

Frame-accurate timecode

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.

Survives a crash

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 & NVENC

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.

16-channel PCM audio

Up to 16 channels of embedded PCM audio, lossless and muxed straight into the file, in sync with picture.

Color pipeline

Set the color metadata per file: primaries, transfer (gamma), matrix and range. Footage lands in the grade tagged correctly, not guessed at.

Scale & frame-rate convert

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.

Editable multiview

Lay out feeds, clocks and overlays, then send a full-screen multiview to a second display.

Know before you roll

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

One screen, full control

Operator screen
Operator screen. Sources on the left, a live preview grid in the middle, codecs and audio meters per input, master timecode and system stats.
Recording in progress
Recording. A lot happens the moment you press record. Each input gets its own encoder, a watchdog catches crashes and stalls, and frames are written so the file survives a power cut. Anything that slips is logged, not hidden.
Multiview editor
Multiview. It's more than a video wall: every feed shows its record status, dropped frames and audio meters, alongside clocks, system stats and alerts you lay out yourself. Style each box, then send it full-screen to a second display so the team can catch a problem the moment it shows.

System requirements

What you need to run it

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.

GeForce vs RTX PRO: H.264/H.265 use the GPU's NVENC encoder. Recent GeForce drivers allow up to 8 concurrent NVENC sessions (older cards fewer); RTX PRO / “Quadro” cards have no session limit, so they're the safe choice for guaranteed 8× NVENC. Encode quality is identical between them.
ProRes is CPU-only: there is no usable GPU ProRes encoder. Roughly 5–6 simultaneous 1080p50 ProRes feeds fit on a 12-core CPU; for more, lower the feed count or move some inputs to NVENC.
Storage: record to a drive fast enough for the combined bitrate of all inputs. A dedicated internal NVMe (or array) is ideal. Portable USB SSDs (e.g. Samsung T7) can work for lighter loads; use the built-in pre-flight write-speed test to confirm any drive before you roll.

Perpetual licenses

Owned, not rented.

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.
