Live Performance

Spout is how live visuals move between applications on a Windows machine. One app sends frames, another receives them — with no file, no network, and no compression in between. It is the standard handshake in the VJ world for a simple reason: the frames stay on the GPU, so the transfer is essentially free. This guide covers the two setups you will actually use — OBS Studio for streaming and recording, and Resolume for mapping and mixing — plus the others that speak Spout, and why VJ Loop Studio 3D is built to be the best sender in that chain. ...

Two systems drive motion in VJ Loop Studio 3D: Audio Link, which follows real sound, and modulators, which generate their own. They target the same thing — any numeric parameter on a clip — and they are often best used together. This guide covers both, and the one behaviour that surprises people: why a render does not match the live preview exactly. Audio reactivity at a glance Audio sources Bass, Midrange, Treble, Loudness (RMS), Detected Beat, Low Blend, High Blend, Body, Spectral Brightness Modulator shapes Sine, Triangle, Saw, Envelope, Random Step, Sample & Hold, Macro Route modes Add or multiply, unipolar or bipolar Tempo Tap tempo, project BPM, tempo-synced modulators Targets Any numeric effect parameter, per clip Audio Link: following real sound Every numeric parameter in the inspector has a small ~ button beside it. Click it to open the Audio Link editor for that parameter. ...

VJ Loop Studio 3D is a generator, not a mixer — so it is built to feed the mixer you already use. There are three ways out of it: Spout for another app on the same PC, NDI for another machine, and rendered files for anything else. This guide covers when to use each, and the specific settings for the apps VJs actually run. Integration at a glance Live to other apps Spout (same PC, GPU-to-GPU) and NDI (same PC or across the network) Live to a screen Fullscreen mirror on any connected display or projector File handover MP4, MKV, AVI, MOV, GIF — H.264, H.265/HEVC, VP9 Confirmed destinations Resolume Arena/Avenue, OBS Studio, TouchDesigner, MadMapper, Notch, vMix, Millumin Latency Spout is frame-local; NDI adds a small network buffer Platform Windows 10/11 (64-bit) Pick a route in one decision Your situation Use Why Resolume/OBS on the same Windows PC Spout GPU-to-GPU, no compression, no added latency Mixer or encoder on another machine NDI Travels over normal gigabit Ethernet Driving a projector or LED processor directly Fullscreen output No third app in the chain at all Handing visuals to an editor, client, or a media server Export a file Deterministic, seekable, no live dependency You can run more than one at once — a fullscreen output on the projector while NDI feeds the stream encoder is a normal setup. ...
