10: Replay and Telestration

Overview

LIVE is constantly in a state of recording whenever there is video input to LIVE. Thus, you can set an in point and an out point to create and save a replay clip. You can also specify a speed of playback for your replay. A default transition can be set when switching to the Replay and Telestration Output via the Settings menu.

LIVE also offers you a set of tools for telestration. With these tools you can draw arrows to illustrate movement, highlight things in your video such as players on a field, and more. Illustrated replay is a powerful feature of LIVE that enhances your ability to offer your viewers a deeper understanding of what they are watching.

Working with Telestration

LIVE allows you to add illustrations to your live video or replay clip, including:

An Arrow tool that allows you to illustrate a trajectory or point to an object in the video

A Freehand tool that allows you to draw on the video.

A Number tool, that allows you to indicate a series of locations or events in the video.

A Spotlight tool that allows you to highlight a player or an object in the video.

A Radial tool that allows you to call attention to any still or moving object in the video by placing a moving circle around it.

A Magnifier tool that allows you to encircle and magnify anything in your video. 

Configuring tools

All tools support animations with the exception of the Arrow and Freehand tool. Once the animation is created, it can be saved on a clip and played together with the clip. Define the position and size of a tool drawing in several keyframes (time points), position and size between the keyframes is automatically interpolated.

See more about Keyframing below.

Add telestration to live video or clip

First, specify what you want to telestrate by doing one of the following.
