For 4:4:4 RGB standard input and output, a similar explanation applies. On capture using the No Conversion
setting, RGB 4:4:4 SDI video black at value (64,64,64) maps to RGB (0,0,0), and RGB 4:4:4 SDI video white
at value (940,940,940) maps to RGB (1023,1023,1023).
With the No Conversion with Headroom option, the maximum possible SDI value range is used. RGB 4:4:4
SDI values ranging from (4,4,4) to (1019,1019,1019) map to the same RGB range on capture.
Enabling Colour Space Conversion on Clip Input
NOTE Headroom in input, output, and preview, is not supported by Blackmagic Design devices, only by AJA ones.
This means that video going through the BMD device always has luminance in legal range.
To enable colour space conversion on clip input:
1 In the VTR Input module, click Engineering.
The Engineering menu appears.
(a) Input Connection box (b) Colour Space box
2 From the Input Connection box, select the input connection.
3 From the Colour Space box, select YCbCr->RGB+Headroom.
4 Capture the material.
Material is captured with headroom and footroom.
To enable colour space conversion on clip output:
1 Open the clip library with the clip(s) you want to output.
2 Click Output Clip and prepare output clip settings.
3 In the VTR Output module, click Engineering.
4 In the Engineering menu, select the output connection from the Output Connection box.
5 From the Colour Space box, select YCbCr->RGB+Headroom.
6 Output the material.
Material is output with headroom and footroom.
Capturing 60i Material with 2:3 Pulldown Removal
Using the VTR Input module, you can capture 30 fps film-based material and convert it to 24 fps material
in real-time as you capture. The procedure for enabling automatic 2:3 removal differs depending on whether
your tape uses non-drop or drop 60i timecode.
To capture 60i material with 2:3 pulldown removal:
1 Set up your capture.
2 In the VTR Input module, click Eng.
