Ptz Control Over Sdi - Blackmagic Design Blackmagic Studio Cameras Manuel D'installation Et D'utilisation

Saturation Setting
The Saturation setting increases or decreases the amount of color in the image. The default
setting is 50%.
Hue Setting
The Hue setting rotates all hues of the image around the full perimeter of the color wheel.
The default setting of 180 degrees shows the original distribution of hues. Raising or lowering
this value rotates all hues forward or backward along the hue distribution as seen on a
color wheel.
Lum Mix Setting
The color corrector built into your Blackmagic Studio Camera is based on the DaVinci Resolve
primary color corrector. DaVinci has been building color correctors since the early 1980's and
most Hollywood films are color graded on DaVinci Resolve than any other method.
This means the color corrector built into your Blackmagic Studio Camera has some unique and
creatively powerful features. The YRGB processing is one of those features.
When color grading, you can choose to use RGB processing, or YRGB processing. High end
colorists use YRGB processing because you have more precise control over color and you can
independently adjust the channels with better separation and more creative options.
When the Lum Mix control is set to the right side, you have the 100% output of the YRGB color
corrector. When you have the Lum Mix control set to the left side, you get 100% output of the
RGB corrector. You can set the Lum Mix to any position between the left and right to get a blend
of output from both the RGB and YRGB correctors.
Which is the correct setting to use? That's up to you, as color correction is a pure creative
process and there is no right and wrong, and the best setting is what you like the most and
what you think looks good!
Synchronizing Settings
When connected, camera control signals are sent from the ATEM switcher to your Blackmagic
Studio Camera. If a setting is accidentally adjusted from your Studio Camera, camera control will
automatically reset that setting to maintain synchronization.

PTZ Control over SDI

Blackmagic Micro Studio Camera 4K supports PTZ output in the form of VISCA commands,
which can be sent to a compatible motorized head. By using a Blackmagic 3G-SDI Shield for
Arduino, you can send pan, tilt and zoom commands over SDI to your Blackmagic Micro
Studio Camera 4K. Your camera will then translate these SDI camera control protocol
commands into the VISCA protocol, and send them to a compatible motorized head via the
9-pin connector on the expansion cable labelled 'PTZ control'.
This means that you can use one SDI cable in a live production environment, to send camera
control commands to remotely control any setting in the camera, as well as send
PTZ commands to a compatible motorized head to control pan and tilt. The pan and tilt
commands will be sent by your Blackmagic Micro Studio Camera 4K to the motorized head,
whereas lens related commands such as iris, focus and zoom commands will be sent to the
active lens that is connected to the camera.
