framerate This setting controls frame rate of the camera. This is
- an approximate setting (in terms of "worst" ... "best")
- because camera changes frame rate depending on amount
- of light available. Setting 0 is slowest, 6 is fastest.
- Beware - fast settings are very demanding and may not
- work well with all video sizes. Be conservative.

- adjusts only V component. However usually it is enough
