Calibrating Video for Broadcast with TriCaster® Scopes
February 15, 2018 by Rex Olson, Chuck Baker
Video that will be televised over the air or via cable has to meet certain requirements in the signal characteristics in order to be broadcast successfully, preserving the detail in the video image for both color values and luminosity. All NewTek production systems and many NewTek software tools include broadcast quality professional waveform and vector scopes for video signal analysis, and proc amp controls for signal adjustments. This tutorial is done on TriCaster®, but applies to NewTek IP Series, 3Play®, NewTek Connect software and hardware tools, TalkShow®, and more.
In this video, Rex Olson explains how what you see in the monitors you are using really does not tell the story with regard to the true characteristics of the video. Different makes and models of monitor can have radically different color gamuts and luminosity ranges and levels. Video that looks perfect on a given monitor may look very different on another, and the signal may be well outside the proper ranges for successful broadcast.
Rex covers those requirements for broadcast video, and shows how to calibrate the video signals on all inputs and outputs to meet broadcast standards. He demonstrates how video looks in the scopes using a variety of images and using broadcast standard color bars. You will come away with the knowledge and skills to ensure your content is suitable for broadcast.
The tutorial goes a step further, however. We live in the age of streaming video over the internet, so Rex explains what you can do with calibration for content destined for streaming that can enhance the look with a wider brightness range and richer colors than broadcast allows for.
We hope this video has been helpful for you. If you have suggestions for other topics you would like covered in a Facebook Live or 2-Minute Tutorial, please send us a message. We will see you next time.
