Using Spout

Scope supports near-zero latency video sharing with other local applications on Windows via Spout. This enables powerful workflows like sending Scope’s output to TouchDesigner, Unity, or Blender in real-time.
Windows only. The Scope server must be running on a Windows machine to use Spout. Spout is not available on Linux (including RunPod).

​
What is Spout?

Spout is a real-time video sharing framework for Windows that allows applications to share GPU textures with minimal overhead. Unlike screen capture or video streaming, Spout shares frames directly through GPU memory, resulting in:
  • Near-zero latency - Frames are available instantly
  • Full quality - No compression artifacts
  • Minimal CPU overhead - All processing stays on the GPU

​
Spout Receiver

Configure Scope to receive video from other applications via Spout. This is useful for using external video sources (like TouchDesigner or OBS) as input for your generations.
1

Set input mode to Video

Under Input & Controls, set Input Mode to Video.
2

Select Spout as source

Set Video Source to Spout Receiver.
3

Configure sender name (optional)

The Sender Name field can be:
  • Empty - Receive from any available Spout sender
  • Specific name - Receive only from a sender with that exact name

​
Spout Sender

Configure Scope to send its output to other applications via Spout. This is useful for post-processing in TouchDesigner, recording in OBS, or using Scope’s output in Unity/Unreal projects.
1

Open Settings

Click the Settings panel in the Scope interface.
2

Enable Spout Sender

Toggle Spout Sender to On.
3

Configure sender name (optional)

The default sender name is ScopeOut. You can change this if you need to identify multiple Scope instances.

​
Compatible Applications

Scope can share real-time video with any application that supports Spout. The following applications have been tested:

TouchDesigner

Use Syphon Spout In and Syphon Spout Out TOPs

Unity

Use the KlakSpout plugin

Blender

Use the TextureSharing add-on
Any application that supports Spout should work with Scope. Check your application’s documentation for Spout integration instructions.

​
Example: TouchDesigner Integration

This example shows Scope sending real-time AI video to TouchDesigner for further processing and output.

​
Basic Setup

  1. In Scope, enable Spout Sender with name ScopeOut
  2. In TouchDesigner, add a Syphon Spout In TOP
  3. Set the source to ScopeOut
  4. The AI-generated video now flows into your TouchDesigner network

​
Use Cases

Live VJ Performance

Use TouchDesigner to mix Scope’s output with other visuals, apply effects, and output to projectors or LED walls

Interactive Installations

Combine Scope with TouchDesigner’s sensor inputs for reactive AI art

Broadcast Graphics

Route Scope through TouchDesigner to NDI or SDI for live broadcast

Game Development

Use Unity or Unreal to incorporate real-time AI video into game environments

​
Troubleshooting

  • Verify Spout Sender is enabled in Scope settings
  • Make sure both applications are running on the same Windows machine
  • Try restarting the receiving application after enabling Spout in Scope
  • Verify the sending application has Spout output enabled
  • Check that the sender name matches (or leave empty to receive from any sender)
  • Ensure both applications are using the same Spout version
  • Spout sharing is GPU-memory based and should have minimal overhead
  • If you see frame drops, check GPU memory usage - you may need to reduce resolution
  • Close other GPU-intensive applications if VRAM is limited
