Utility Menu - Silicon Imaging SI-2K User Manual

Utility Menu

Always leave the MAIN MENU and go to the UTILITY MENU, when you first
start the camera to make the basic settings and create a project name. Ac-
cess the UTILITY MENU from the upper right corner of the MAIN MENU.
Each time the Record mode is entered, a new file will be created in the Project
directory with a file name of the project followed by a timestamp. This creates
an easy sequence of takes automatically.
Camera Preference Menu (CAM PREF)
Basic information about the operation of the camera is set in this menu.
•
Number of Buffers
This is the number of frame buffers used by the DVR to store incoming camera
data prior to Cineform RAW™ encoding. These buffers can be used to extend
recording time when the encoder can not maintain the rate of incoming data –
encoding continues and the buffers slowly fill until recording must be stopped
to allow the buffer to empty. This is important for high frame rate shooting, 2K
modes and scenes with a very high level of complexity as this slows the encod-
ing process. TAKE CARE ! The number of buffers you choose diverging from
the default setting could impact camera's stability.
•
Defective Pixel Detection Map
Most defective pixels are automatically found and replaced using the black
reference. If known pixels are bad, a separate file indicating each bad pixel can
be created. The format is a tab delineated text file with an x coordinate, <tab>,
y coordinate <cr> for each bad pixel.
• Default Boot Frame-Rate / Resolution
This is the default value for the camera and may be set to new values else-
where.
• Cineform RAW Compression Quality
Adaptive Mode) The adaptive recording mode will dynamically change the
compression to meet the scene complexity, maximizing the quality setting while
preventing the RAM buffer from overflowing. So if the camera changes to Qual-
ity level 1, it will, when presented with a scene that can be recorded at Quality
4, increase the quality back up that higher setting. After a recording is finished,
the last recording quality setting is used as initial starting point. Should a scene
have changed radically, the recording will very quickly go back up to Quality
4 once the recording starts back up. You will not be „stuck" at Quality 1 if the
scene can be encoded at a higher quality setting.
