b3LAB – Cases

Concrete b3LAB workflows for VJs, live artists, colorists, streamers, educators, and creative technologists. Each use case is a small, real signal path — across audio, realtime visuals, post hosts, virtual camera, and clean delivery.

Routing · PortalOFX+ Presence · b3WebCam+ Control · PulseOSC+ Delivery · BatchForge+ macOS · Syphon · NDI · OSC

Realtime apps → Post tools

Live frames go straight into DaVinci Resolve Studio or Assimilate Scratch / LiveFX, then back out as Syphon or NDI — no capture-card detour, no export loop.

CASE 01

Stage visuals into the documentation cut

A dance company runs live, motion-tracked visuals on the back wall — TouchDesigner reacting to the dancers. The doc cut needs the same on-stage frames, not a re-render. PortalOFX+ pulls the TouchDesigner output straight into Resolve while the show plays. One Mac runs the show; the editor cuts with the actual on-stage frames the next morning.

CASE 02

MadMapper test patches into the showreel

A projection-mapping artist needs new test patches in next week's spec reel. Before: screen-record MadMapper, import, scrub for the good frames, hate the resolution. With PortalOFX+: MadMapper publishes NDI, Resolve cuts it live, color-grades inline. Reel finished tonight, not next weekend.

CASE 03

Live-coded visuals as a comp layer during a multi-cam take

A band records a live take while a Hydra patch generates a reactive overlay. The director wants to see — during soundcheck — how the visual layers under the multi-cam edit. PortalOFX+ pulls the Hydra NDI directly into Resolve as a track. Composite preview is live, the call about "more or less visual" gets made before the take, not in the edit.

Syphon / NDI → Camera output

View, multiview, correct, record, and expose live visual sources as a system-wide virtual camera for Zoom, Teams, Safari, FaceTime, OBS, TouchDesigner.

CASE 04

Reactive cover art as the stream cam

A DJ streams a 90-min set on Twitch. Static avatar = boring; full screen-share = laggy. VDMX renders an audio-reactive cover-art animation; b3WebCam+ exposes it as a system camera; OBS picks it like any cam. Viewers get a moving brand image, the DJ stays out of the frame, no extra hardware.

CASE 05

B-roll clips routed through the camera input

A podcaster wants short demo videos to play during interviews — without screen-share that breaks the cam framing. Mitti plays B-roll as Syphon; b3WebCam+ exposes that as a webcam; Riverside.fm and Streamlabs see it as a second camera input. Cuts to B-roll as cleanly as cuts between hosts.

CASE 06

Architectural walk-through as a "camera" in a Teams call

An architect needs to walk a remote client through a Twinmotion model in a Teams call. Screen-share kills the framerate. Twinmotion publishes Spout/Syphon; b3WebCam+ becomes the system camera; Teams picks it up at 60fps. Client sees rooms in motion, architect controls the mouse.

Audio → Visual control

Turn mic, file, or soundtrack input into 52 structured OSC values for TouchDesigner, Resolume, MadMapper, Synesthesia, VDMX, Max — built for low-latency live response.

CASE 07

Sound bus triggers light scenes via OSC

A small theater company runs without a dedicated lighting designer at every show. PulseOSC+ listens on the audio bus and broadcasts beat / band envelopes as OSC. QLab catches the cues and triggers grandMA scenes via OSC bridge. Lights and music breathe together for the full eight-night run, no operator at the cue desk.

CASE 08

Recording session with pre-synced visual takes

A music producer records a take in the studio. Future music-video footage needs to feel locked to the audio — but composing visuals after the fact is a sync nightmare. PulseOSC+ broadcasts envelopes from the live take; TouchDesigner renders reactive material in real time, recorded in parallel. The visual track is already audio-synced when the take ends.

CASE 09

30-second loop, voice-perfectly-aligned

A generative artist wants a short Instagram-ready loop that reacts to her own voice memo. Hand-keyframing waveform animation by ear takes a day. PulseOSC+ analyzes the voice file, broadcasts envelopes to Cinema 4D / Octane. The loop is voice-locked in one render pass — drop-ready in an hour.

Rendered output → Show assets

Batch-create HAP, ProRes, HEVC, H.264, WebM, image sequences, and audio masters locally — no CLI, no cloud, no telemetry.

CASE 10

12 talks, three deliveries, one watch folder

A conference ends 18:00 with twelve ProRes talk recordings sitting in a folder. Marketing needs YouTube 1080p, LinkedIn-square, and sponsor-logo-overlay versions by 20:00 — none of which is sane to do by hand. BatchForge+ watches the folder; each new file triggers all three preset chains. Twelve talks, three formats each, marketing has 36 deliverables before dinner.

CASE 11

Editor handoff to color, screening copies for producers

A documentary editor wraps a Premiere cut Friday afternoon. Color is doing the grade externally on Avid; producers want H.264 screening copies on the shared drive. Before: stay until 22:00 hand-encoding two passes. With BatchForge+: drop the cut, run DNxHR + H.264 presets, leave at 18:00. Both files land on the share over the weekend.

CASE 12

One EXR sequence, three pipelines

A game studio's cut-scene comes out of Houdini as a 4K EXR sequence. Three downstream targets: H.265 for the Unreal build, ProRes for the external VFX house, WebP-sequence for the marketing trailer. BatchForge+ runs all three from the same source in one pass. No cross-team file-format negotiations, no re-renders.

The whole signal path

When a single tool isn't enough — workflows that connect audio, realtime visuals, post hosts, virtual camera, and clean delivery in one signal chain.

CASE 13

Eight-night theater run, one tech volunteer

Audio bus → PulseOSC+ → light cues. Stage visuals → PortalOFX+ → doc-cut Resolve. Each night → BatchForge+ → next-season promo compilation. Setup once, run eight nights, season highlight reel ready for box office before next season's posters drop.

CASE 14

Sunday morning, one volunteer, the whole service

A church service runs 90 minutes with one tech volunteer. ProPresenter → PortalOFX+ → Resolve Live mix. Audio bus → PulseOSC+ → Resolume stage visuals. Service output → b3WebCam+ → vMix stream. Recording → BatchForge+ → overnight YouTube sermon plus audio-only podcast. Service ends at noon, sermon online before lunch.

CASE 15

Quantum-optics outreach, live to thousands of kids

A university lab streams open-door demos. Microscope NDI + sensor-data TouchDesigner patch + lab-mic audio. PulseOSC+ feeds reactive visuals; b3WebCam+ exposes the composed feed; OBS streams. Researchers explain on camera while the data visual breathes with the experiment. Post-event, BatchForge+ encodes versions for each downstream platform.
