The delay is caused by a couple processes: 

1. Encoding video and audio in the phone/camera device: This usually adds up to 1/2 second.

2. Sending the video to the Director device: This can add 1 to 1 1/2 seconds, depending on the internet connection where you’re using Director. 


We’re constantly working to reduce the delay on the switching. We will roll out updates as they are ready.
