During the last decade, major changes have occurred in professional video production. Computer technology has been embraced; HD has replaced SD; and the CRT display has been superseded. All of these changes have introduced challenges in establishing and maintaining the intended image colours. Computer graphics subsystems (both hardware and software) use different colour coding parameters than video; HD colourspace is somewhat different than SD colourspace; and emergent displays don’t share the same colour physics as CRTs. In the consumer arena, fixed-pixel displays – mainly LCD, but also plasma panels – have become the norm. Production methodology needs to be adapted to the new technology and standards, keeping in mind SD compatibility. In the near future, we can expect IP-based distribution to become increasingly important; attention needs to be paid to colour parameters in video intended for IP transport. It is important for content creators to understand the differences in image presentation between PC and CE technologies, both in the studio and in the consumers’ premises.
In this 1‑day workshop,
Charles Poynton will review how colour is encoded in digital still images and in digital video, SD, HD, and computer graphics. He will explain how creative intent is supposed to be preserved, how that goal is often compromised, and how video production artists, editors, and technologists can make the most of the situation. Knowledge of colour science and colour image coding is useful in colour correction; Charles will explain several colour correction schemes. He will outline image data representation and file format issues. He will describe how viewing conditions affect colour appearance, and explain how faithful image display can be achieved in the studio and in consumers’ premises.
Who Should Attend: The webinar will be suitable for people in positions such as these:
- Video graphics designers and artists
- Video compositors, colorists, and editors
- Technology managers
The attendee should be very familiar with the technical aspects of creation and manipulation of digital imagery and motion sequences. Detailed handout notes – some of which form portions of the second edition of Mr. Poynton’s book – will be provided.
