b3LAB – b3Player Pro

The broadcast-accurate player & signal hub for macOS.

Frame-accurate playback with 10-bit DeckLink output (v210), NDI® and Syphon in and out, a cue playlist, OSC control with Mitti sync, scopes, overlays, FFGL effects and export. Metal-native, with bundled FFmpeg — no terminal and no setup.

// SOURCE FORMATS

Plays what you throw at it.

  • H.264 / AVC, HEVC / H.265, ProRes — hardware decoding via VideoToolbox; HEVC with HDR (PQ/HLG); ProRes incl. 4444 with alpha.
  • DNxHD / DNxHR, MPEG-2 / XDCAM, VP9, FFV1, MJPEG — decoded with the bundled LGPL FFmpeg; DNxHR up to 12-bit, FFV1 for lossless archival.
  • HAP / HAP Alpha / HAP Q — custom decoder (BCn → Metal) for VJ and live workflows.
  • Image sequences — DPX, TIFF, PNG, EXR, JPEG with custom sequence FPS. Stills with adjustable hold, also as a playlist cue.
  • Audio-only — WAV, AIFF, MP3, M4A, FLAC and more play as a black frame with sound.

// OUTPUTS

One Program, every output.

A single shared Program feeds DeckLink, NDI® and Syphon at once — same image, timecode and v210 path.

  • DeckLink (SDI) — 10-bit end to end. True 10-bit v210 computed on the GPU. Scheduled playback with its own device clock, audio over SDI (up to 16 channels), RP188 timecode, HDR over SDI (PQ/HLG, Rec.2020) or tone-mapped SDR.
  • NDI® Output — Program over the network (8-bit).
  • Syphon Output — Program as a texture for other macOS apps, with a custom name.
  • sRGB option — convert the Rec.709 Program to sRGB for NDI and Syphon receivers.

// INPUTS

Files and live sources.

Live inputs go through the same Program stage, so overlays, scopes, effects and every output apply to them too.

  • NDI® — receive from the network.
  • Syphon — a texture from another macOS app.
  • DeckLink — SDI input (8-bit).
  • Cameras — any connected camera.
  • Screen capture — a display, window or app (ScreenCaptureKit), with sound for SDI/NDI, optional mouse pointer and transparent background.

// PLAYBACK & CUES

Frame-accurate, cue-driven.

  • Transport — own playback clock, JKL shuttle, varispeed, reverse playback even for long-GOP, In/Out marks, A-B loop, markers and stop at next marker.
  • Playlist — files, inputs, charts and spacers, by drag & drop. Per-cue switches for fade, loop, goto, pause and transitions.
  • Cue inspector — in/out, playback speed 6–6400 %, play counts, fades, level −60 … +12 dB and OSC at start/end.
  • Folder mode — play a whole folder, recursive or random, without building a playlist.
  • Mitti — import a .mitti2 project, Follow Mitti (sync) or Drive Mitti (control).

// OSC & AUDIO

Remote control and sound.

  • OSC in and out — control via /b3player/… (transport, cues, overlays, outputs, every menu action), feedback to /b3player/status/…, per-cue messages with placeholders.
  • Audio routing — sound over the Mac (delayed to match SDI) and/or over SDI/NDI, up to 16 channels, solo, meters and waveform.
  • Varispeed audio — forward 25–800 % with pitch correction (WSOLA); reverse is silent, like tape.
  • Tone generator — 100 / 400 / 1k / 10k Hz, EBU and SMPTE reference levels.

// MONITORING

Scopes, overlays and viewing aids.

  • Scopes — waveform, parade, vectorscope and histogram in Metal, each scrubbable, also in a floating window.
  • Overlays — timecode, time left, marks, safe areas, center cross, blanking, chart, countdown, meters, grid and more.
  • Viewing aids — false color, focus peaking, R/G/B channel isolation and 1D/3D LUTs (.cube) as monitoring aids.
  • TIME / countdown — Realtime, Duration, To and multi-line Text modes, with its own Syphon server for stage and control room.

// IMAGE

Color, alpha and effects.

  • Color and HDR — Rec.709 / BT.1886 playback, HDR (PQ/HLG) in the window via EDR, 10-bit end to end on SDI.
  • Reframe and alpha — zoom, pan and flip, alpha matte with checkerboard background, clean premultiplied alpha outputs.
  • FFGL effects — effect chain from Resolume "Extra Effects" and your own folders, applied to window and outputs alike.
  • Test chart — built-in chart with its own clock and running timecode.

// EXPORT & TOOLS

Export with burn-in.

  • Export via bundled FFmpeg: ProRes (all profiles, 4444 with alpha), H.264, HEVC and HAP, with timecode track and audio.
  • Selectable burn-in — timecode, safe areas, scopes, meters, TIME, FX, LUT and viewing aids.
  • Source — the file in the player, the playlist as one film, or each cue as its own film.
  • Screenshots as PNG or JPEG, a fully re-bindable shortcut editor, and appearance settings.

// LICENSE

€29, one license per person.

  • Demo (unlicensed) — full viewer at full frame rate, all inputs usable, no time cap. Outputs (DeckLink, NDI, Syphon) run at 2 fps with a banner.
  • Pro (licensed) — €29 — everything without limits, outputs at full frame rate.

Activate with your license key in the license panel. Status shows under App ▸ License.
