Picture in Picture
The Picture in Picture element combines two inputs into a single output by overlaying a smaller video on top of a main source, or by placing videos side by side. Use it for facecams, secondary angles from a separate device, a co-stream from a friend, or advertisement videos alongside your ongoing stream.

Settings
Adjust the input's size as a percentage of the canvas.
Change the input's position. The top-left corner of the canvas is 0,0.
Crop the incoming video from the left, right, top, and bottom. Cropping is applied before scaling.
Mute the input's audio so only the main source audio is heard.
Synchronize the input's timing with other sources. Value is in milliseconds (e.g. 1000 = 1 second). Allowed values: 0–4000. Note that inputs may drift out of sync if network issues cause buffering.
