How to setup multi-speaker AutoCut

Included in

AutoCut

Ready to handle panel discussions and town halls like a pro? This guide will show you how to set up multi-speaker AutoCut to automatically switch between speakers, making your productions dynamic and engaging. Let's dive in and make your multi-speaker events a breeze to manage!

The AutoCut algorithm supports you in your everyday productions by automatically cutting between different camera angles and moving PTZ cameras around based on the content of the video and audio feeds.

For more information on how AutoCut works and what it can and cannot do, see the AutoCut page.

WARNING

This guide is for setting up AutoCut in a multi-speaker scenario. If you want to set up AutoCut for single-speaker scenarios, see the AutoCut setup guide.

Scenario description

Multi-speaker AutoCut is designed for recording town halls, panel discussions, and other scenarios with multiple speakers. It is required to have an individual audio feed for each speaker. The following shots and inputs are supported:

• A static stage show that shows the whole scene (e.g. stage or hall) - required
• A speaker camera that moves to speakers (with or without AutoTracking)
• A video feed of the presentation slides
• A PiP of the speaker and the slides
• A camera that points at the audience
• Multiple audio feeds (at least one for each speaker)

INFO

In multi-speaker scenarios, AutoCut listens for active speakers and automatically switches to the appropriate shot - either by jumping to a preconfigured preset or by guiding a camera to that position first.

Setup the project

Setup a new project and add all necessary devices. For more information, see the project setup guide.

You need at least one stage camera, one speaker camera and one audio feed for each speaker. The other device are optional and depend on your use case.

Video feeds

First, you need to decide how to route the video feeds into MiruSuite. You can use NDI, MJPEG, or a capture card. This depends on your setup and the available hardware.

One common setup is to use NDI® or MJPEG for the PTZ cameras. For best tracking results, we recommend using a capture card for the speaker camera.

The presentation can also be routed via NDI®, for example using the NDI Tools.

TIP

It is also possible to feed the multi-cam view of your switcher into MiruSuite and crop into the different camera feeds. This is enough when you don't need auto tracking.

Common setup example

• Stage shot:
  • Static camera (connected via HDMI or SDI to the switcher + MiruSuite)
  • Capture card
• Speaker 1:
  • PTZ camera
  • NDI®
  • Programmed presets for every speaker
• Speaker 2:
  • PTZ camera
  • NDI®
  • Programmed presets for every speaker

Setup devices

Connect all devices to MiruSuite and add the necessary components. If you start with the AutoCut controller, it will tell you which components are missing, e.g. a Speaker camera needs a PTZ Controller, an Audio device an Audio Input, etc.

Switcher setup

Connect MiruSuite to your switcher. For more information see Switcher connection.

On the Switcher page, make sure to assign the correct switcher input to each camera in MiruSuite.

TIP

To use a PiP shot, you need to add the presentation input and the switcher input. In the AutoCut controller of the speaker, select the desired PiP input.

Most switchers have this feature built-in. If you're using vMix, you will need to add a new input and combine the speaker and presentation feed to a single feed. You can find more information in this vMix tutorial.

Program presets

Set up camera presets for each speaker camera. For optimal results, we recommend assigning multiple presets per speaker from different camera angles. This enables AutoCut to respond more quickly and produce more dynamic cuts.

To configure, open the AutoCut component of each speaker camera and assign the corresponding speaker’s presets.

Enable AutoCut

Once all devices are connected and configured, navigate to the AutoCut page and toggle the activation switch in the upper-right corner. The startup wizard will guide you through selecting a cut style, choosing the shots you want to include, and finally clicking Start AutoCut.

Monitor AutoCut

You can follow AutoCut’s live decisions and detections on the AutoCut page. If needed, you can override its choices manually using either the virtual switcher in the Switcher view or your hardware switcher. MiruSuite will adjust accordingly and continue from the new state.

WARNING

Due to RossTalk limitations, feedback from Ross switchers is not currently supported. To allow AutoCut to adapt to manual overrides, use the virtual switcher in the Switcher view.

You can also override the currently dominant speaker via the button or hotkey below every audio input. This forces AutoCut to switch to this specific speaker. Click the Override button or hit the related hotkey (visualized next to the button) to activate the override. Make sure to deactivate the override again.

Excellent! You've now configured multi-speaker AutoCut. Your productions with multiple speakers will be more professional and easier to manage. Enjoy the power of automation and happy directing!
