Common Situations:
Bad Video Output
Symptoms:
One or more of the outputs are seeing something on the video output that is not usable for TV production. This could appear as wavy green lines, a "jumpy" output, no signal at all (black), flickering images, pixelated video, or other abnormal video quality issue. These issues could be a symptom of several root cause problems, depending on the nature of the display and which outputs are being used.
Reference in Workstation?
Though external inputs (camera's and decks) do not require Genlock in
order to work with our system, the main workstation and any related
parts from the factory require an analog composite (480) signal at all
times.
-In the case of a Slate 100, Slate 1000 or a Slate 5008, your genlock signal (composite video) should connect to the bottom
right-hand BNC connector (if you are looking at the back of the Computer Workstation), preferably
from a reference generator of some kind. In a pinch, you can use a composite
output from an old deck/camera/dvd player, as long as that same device is
not being used as an input in the system (because that would create an unwanted
looped signal.) This device must remain on at all times to provide a valid genlock.
-In the case of a Slate 2100, Slate 3016, Slate 3032, Slate 5016, or Slate 5032, your reference signal is looped through your iBoB or Router before going into that bottom
right-hand BNC on the Computer Workstation.
- Check Slate IO Assignments
Check your settings in the Slate IO assignments window. If
you are working with an HD card, for example, make sure the output in I/O Assignments is
set to the same format as the monitor or deck connection being used. Analog inputs and outputs can be toggled between composite, component (YUV)
and s-video (Y/C). If the connection on the monitor does not match,
try toggling through the choices.
- Check external devices and adaptors
Follow the cable path outwards. After the signal leaves the
Broadcast Pix, does it travel through any connectors or adapters? Try a different cable that may have a better connection or
crimp. Try another monitor or deck that you could use to test
the signal.
Check Signal Directly
There are up to 5 Outputs on the back of the Computer Workstation. Output A and B are both SD-SDI format, Output C is Analog and can be used as either Composite, Component (YUV), or S-Video (Y/C) through settings in the Slate IO Assignments window. Additional outputs (outputs D and E) depend on the number and type of I/O cards in the system configuration. Output D (on the first I/O card installed) will always be the same signal type as its Inputs 1-4; Output E (a second I/O card, if installed) will always be the same signal type as its Inputs 5-8. To test the outputs, connect each individual output directly to an external monitor and see if the same problems continue. Remember that the output signal from the card must match the monitor's signal input requirements. If the signals appear normal, check your other devices in the workflow that may be introducing the problem.
- Loop Back
Try running the questionable output of the Broadcast Pix Switcher back into one of the card's inputs. See if the video looks the same on the Multi-View as it does on your monitor/deck.
- Contact Support
If none of these steps work, please contact
Broadcast Pix Technical Support and they will assist in further
troubleshooting of this situation and help to resolve the matter fully.
