1-2 FilmStream mode Viper
To operate in the FilmStream mode you must ensure that the camera
is switched to this mode. The output signals and the control functions
that are available depend on the mode you select.
The factory default for the mode setting is the FilmStream mode, so
normally you do not have to switch modes to operate the camera as
a digital film camera.
If a different mode has been set up, then you need to switch to the
FilmStream mode by changing a menu setting (for more details refer
to Section 5).
To change modes:
1.
Open the menu system.
2. Go to the Install menu.
3. Select Output mode item.
4. Change the value to FilmStream or HDStream .
The camera remembers the last selected mode, so it remains in the
FilmStream mode even when switched off and on again.
Monitoring
To provide a monitoring signal for viewing, a separate channel is used
which undergoes some video processing to make it acceptable for
viewing on monitors and viewfinders. Although derived from the same
sensor signals, this channel is entirely separate from the main FilmStream
output.
The Viper does not have any adjustable visual parameters for the
FilmStream outputs. Framing, focussing, exposure setting, shutter
angle and optical filtering are the only operations required of the
camera and lens operators.
