Clearly, the traditional setting of BT.709 as described does not do justice to the HDR capab ilities that are latent within the 15 -stop dynamic range of the image sensor. A different re-mapping of the camera settings are required to fully exploit this 15 -stop DR. In addition, t he subsequent OE TF specified by BT.709 must also b e replaced with a form of logarithmic OE TF to help ensure preservation of the full 15 - stop range – this will be discussed in a separate paper .

Displaying Onscreen Markers, Zebra Patterns and False Color with EOS C700 models
|
Using onscreen markers allows you to make sure your subject is correctly framed and is within the appropriate safe area. The zebra patterns help you identify areas that are overexposed. The false color display allows you to check if the exposure is correct.

The EOS C700 offers broad options in 4K / UHD origination and capture – and a pivotal design strategy was to address this 4K focusing challenge. An innovati ve electronic viewfinder (EVF) u ses a 0.7 -inch OLED panel having fu ll 1920 x 1080 resolution to offer the cinematographer a significant aid t o focusing. The camera also embodies the latest in the Dual Pixel CMOS Auto Focus system which , in combination with face detection , supports a variety of options in precision auto focusing.

The discussions in the White Paper (Deep Dive Part 1 ) centered about the all -important linear representation of the camera video. Now that video must be further “prepped” in a manner that can help ensure that the extensive dynamic range created by the imaging system will be fully protected while being recorded – and also as it is transported over industry standardized interfaces. This is the primary role of the camera’s Optoelectronic Transfer Function (OETF).

In seeking the very highest performance for 2K / HD , the three full bandwidth RGB 4:4:4 componen ts are recorded at 12 -bit or 10 -bit at the v ery high data rates shown in Ta ble 4 . Variable Bit Rate ( VB R) is deployed in this mode because it more f lexibly and accurately encode s the video data , with fewer bits ass igned to less demanding segments of an image frame and more bits used in difficult -to-encode segments. The file wrapper is MXF.
