 This panel contains all settings of the camera used for filming the movie
 which is currently being edited in the Clip editor.
+Different predefined settings can be used here and can be chosen from the panel header.

-Camera Presets
-   Predefined settings can be used here.
-   But such settings as distortion coefficients and principal point are not included in the presets and
-   should be filled in even if camera presets are used.
-Sensor
-   Width
-      Is the width of the CCD sensor in the camera. This value can be found in camera specifications.
-   Pixel Aspect Ratio
-      Is the pixel aspect of the CCD sensor. This value can be found in camera specifications,
-      but can also be guessed. For example, you know that the footage should be 1920×1080,
-      but the images themselves are 1280×1080. In this case, the pixel aspect is: 1920 / 1280 = 1.5.
-Optical Center
-   Is the optical center of the lens used in the camera. In most cases it is equal to the image center,
-   but it can be different in some special cases. Check camera/lens specifications in such cases.
-   To set the optical center to the center of image, there is a *Set Center* button below the sliders.
