In this tutorial an optical feedback is created. Feedback is used for example as an effect for club visuals, and is associated with an audio signal.
1. Open the desired clip in Live Editor. (A)
2. Pull the video via drag&drop from the Live Editor into the Layermanager. (B)

Tooltip: Feedbacks loop Live Video streams back into the compositing, and are therefore extremely dynamic. With Feedback, image and video material can be handled in an extremely generative and interactive manner.
Feedback can quickly lead to extreme results that are either completely black or completely white, which can be distracting, especially when using LEDs. A special LED_WALL_Equalizer effect can help as ‘Final Effect’ to prevent excessive output. |
