Video Switching Fundamentals

Many pictures in, one picture out, and what decides whether the change is clean

The switcher is where a live video show is actually made. This book covers what a switcher does in the signal chain, why every source must agree on format AND on timing, genlock and frame synchronisers, program and preview and the mix/effects banks above them, the take and how to place it, the three core transitions and what each one says, keying from the lower third to the chroma key, the downstream keyer, tally, embedded audio and lip sync, clean feeds for streaming, working to a director and a run of show, and how to stay calm on a desk that has no undo.

Inside: What a Switcher Does - Program, Preview & the Take - Transitions - Keying & Layers - Switching a Live Show - Where to Go Next.
