Adding A Camera
Creating a camera is the first step in adding equipment to your project.
A camera should be created for every different type or operating mode of camera you plan to use with the CinCraft Scenario system.
For example, if you are planning on using a single ARRI Alexa camera but in two different operating modes, then it would be necessary to create a camera in the equipment manager for each mode.
However, if using two cameras that are the same model and have an identical configuration, then only one camera in the equipment manager would be needed.
To add a camera, simply navigate to the equipment manager page and press the “Add Camera Configuration” button
This will bring up the camera adding dialog
CinCraft Scenario includes a database of commonly used cameras and their operating modes. From the dropdown menus, simply select the appropriate choices for your camera.
The camera image area on the right is used to double check that the sensor settings are correct. The yellow lines should match the area of the camera picture. If magnification or operator HUD is causing the image to be scaled then the yellow lines can be simply adjusted by clicking and dragging them to fit the image
This is important, as any error in sensor size configuration will cause poor tracking results
If your camera or mode is not listed then the “Manual” tab allows you to enter in the details of your camera and the relevant sensor size information.
Sensor size information can typically be found inside camera documentation
If the camera applies a sensor crop in the chosen operating mode, it's vital that this cropped sensor size is used and not the overall sensor dimensions
It is important to understand that certain cameras can apply a scaling or magnification effect on the monitor output depending on user settings.
The Surround View or Lookaround options on ARRI and RED cameras for instance will increase the used sensor size from the documented dimensions
The operator's HUD on cameras can also cause confusion when it's opacity is set to 100%. As it will appear that the sensor is being cropped due to the operators overlay
Some cameras will render the overlay on top of the camera image, this overlay can be fully opaque, this means it will look like the camera is in a different sensor mode as the aspect ratio will not match. When working with overlays like this it is recommended to turn the opacity down so that the Yellow box can be set correctly
Camera is in a 16x9 sensor mode with overlay opacity set to 0%
Same sensor mode but camera appears to be in a WS format due to operators overlay set to 100% opacity
This setting is designed to show the camera operator more of the frame. It works by increasing the active sensor area that is used. In the images below the same sensor mode is being used but there is a clear change in magnification between the two images.
Surround view is switched off and the documented and actual sensor size match
Surround view is enabled and a effective change in sensor size is present
In this example it's vital that the "yellow" lines in the add camera dialogue are matched to the black frame lines in the right hand image that represent the documented sensor size
