To increase the framerate it is possible to compress the data that is moved from the camera to the computer.

Type Select wich type of compression to use:
  • None - No compression will be done.
  • Automatic - The camera will try and find the best compression, all you have to do is tell it what framerate and quality you want.
  • Manual - The camera will send those pixels that changes more that what the Y Quality and the UV Quality settings specify.
Decimate Only half the scanlines will be captured.

Settings that have a meaning when Automatic is selected:
  • Target/Framerate/Quality - This is what the hardware manual says: The Framerate and Quality parameters are used to determine the actual target rate/level for a target parameter and the minimum acceptable level/rate for the untarget parameter. Play around with the parameters, and you should get a feeling on how they work.
  • Decimate If decimation is enabled the camera will only use it when the framerate can not be met otherwise.
Settings that have a meaning when Manual is selected:
  • Y Quality/UV Quality - Sets the thresholds for Y (chromatic) and UV (color) components.
    Lower value gives a higher framerate, but decreses the quality.
    If you don't know what Y and UV means, just set them to the same value.
