Video
The XLV offers 2 video outputs:
- one clean
- one with framelines and text output
The output functions can be set by a service technician.
Connect a BNC cable to the desired output.
Note: For multiple monitors it is better to loop them together, with one monitor's
output feeding the next monitor's input, rather than using a T connector to split
the signal.
RS-232
The XLV has 2 serial ports [5 pin Lemo 0B] for external control. Port A is used for
loading software, and direct control of video parameters. Port B is used for Panatape
input.

GAIN & [+/- ]
With the GAIN switch set to manual [left] position, use the [+/- ] switch to increase / decrease
picture brightness. Note: increasing gain amplifies the video signal and therefore also increases
video noise.
Frameline Brightness
GAIN, [+/- ], & CLR
Set the CLR/BW switch to CLR. With GAIN switch in Boost Auto [middle] position, use the [+/- ]
switch to brighten or darken the framelines.
Mask Density
GAIN & [+/- ]

Gain Control
XLV
Normal Auto Gain Control [AGC]
Setting the GAIN switch to the rightmost position enables the standard gain setting,
producing reduced video noise, darker shadows, better highllight detail, and in most
cases a more pleasing image than Boost AGC. The camera will automatically adjust
brightness for changing scene conditions. AGC target is adjustable via the panel
switches [see p11].
Boost Auto Gain Control
With the GAIN switch in the middle position, the XLV will automatically adjust the gain
level to attain a brighter image. Use this position in extreme low light situations when
maximum picture brightness is required.
Note: in many situations this will result in significant video noise, therefore, Normal
Auto Gain may be preferable.
Bright Scenes
For bright scenes, when no signal amplification [GAIN] is required, it is usually best to
set the GAIN control to the Manual [leftmost] position, and then use the [+/- ] switch to
bring the GAIN all the way down to zero. If the picture is still too bright, use the manual
iris control and the ND filter on the XLV to adjust the picture brightness.
Scenes with changing brightness
In situations where scene brightness changes, i.e. panning from a shaded to a sunny
area, it may be advantageous to set the GAIN control to the Manual [leftmost] position,
and use the [+/- ] switch to adjust the GAIN to the desired level. The XLV will hold this
setting and will not try to compensate for changing light levels.
Dark Scenes
When shooting in low light situations, make sure the ND filter is disengaged, and the
video manual iris is all the way open. Try setting GAIN the Boost AGC [middle] position.
If this results in too much noise, try the Normal AGC [right] setting.

Frameline & Text output
Setting Framelines
XLV
The XLV provides 2 independent sets of framelines, which can be adjusted to any film format.
Follow these steps to setup the framelines:
1. Make sure you are viewing the frameline output.
2. Push the SEL/MOD switch towards the MOD position until you see the frameline set to be
changed.
The MOD switch cycles through 4 modes: Frameline A, Frameline B, Frameline A+B, No
Framlines.
3. Push the SEL/MOD switch towards SEL until the left side of the frame blinks as a dashed
line.
The frameline setting will automatically be saved, and the frameline will stop blinking, if no
switch is pushed for a period of 2 seconds.
4. Push the [+/- ] switch in the appropriate direction to move the line.
Repeat steps 3 & 4 for all sides of the frameline.
Repeat steps 2 through 4 to adjust the second set of framelines.
Note: If you only see one set of framelines when selecting with the MOD
switch, one set could be hiding behind the other. Adjust the visible
frameline to a smaller size, so the other set becomes visible.
Once the frameline position has been set, you can adjust the freameline brightness and the
density of the surrounding mask area [see p11]

Turn the thumbwheel segment on front of the optical focus tube. Pushing towards
camera lens mount inserts the ND filter into the light path, pushing the other way
removes the filter.
Focus
Open the cover on the top of the video optics tube. Turn the thumb-knob control to
adjust focus until the crosshair or grind of the ground glass is at its sharpest point. The
Panaglow framelines are on the other side of the ground glass, and may still be slightly
soft due to the shallow depth of field at the plane of focus.
Horizontal Position
Use a philips screwdriver to turn the adjusting screw [see diagram], moving the image
left or right.
Ver tical Position
Use a philips screwdriver to turn the adjusting screw [see diagram], moving the image
up or down.

As a part of our program of continual improvement to our products and services, Panavision
welcomes your feedback regarding any problems, questions, or comments. Please contact
your local Panavision office which supplied the equipment.
Some problems are solvable in the field. Please see the following list for some troubleshooting
tips.
For immediate assistance with any equipment problem, please contact the technical or service
department at your local Panavision office.
- Video won't power up
Make sure XL camera has power
Try a different battery
- Red light is lit, but no picture
Check BNC cables and connections
Run a BNC cable from a known good video source to the monitor. If that picture is ok,
connect the same cable to the XLV.
Try the other video output
- Noisy or grainy video image
Use Normal AGC or Manual gain. See Gain Control section, p13, for more details.
- Framelines are soft [out of focus]
When the video is properly focused on the crosshair or grind of the ground glass, the
Panaglow framelines may appear soft, due to the distance between the 2 surfaces, and
the shallow depth of field at the ground glass.
No picture, No power [red LED is not lit]
Call Panavision and report the problem. Set aside all video and power cables and
batteries connected to the camera at the time of the failure. Make note of all
accessories and external devices [monitors, playback decks etc.] connected to the
camera system. This information will help our technicians repair the video and prevent
future problems on your set.
Image is soft when ND filter is engaged, but sharp without it.
ND gel filter may be warped. Call Panavision to have filter exchanged.

Troubleshooting
XLV
- Moving the Gain switch between Normal and Boost doesn't do anything.
If the video image is either very bright or very dark, both settings will look the same,
because either setting will eventually go through the whole range of adjustment
between 0 gain and max gain.
To test the function, try a lighter or darker scene, or try opening or closing the iris.
