Appendix 1
Reference
Select whether the external analogue reference input is Tri-
Level or Black & Burst. No reference needs to be applied
unless 'Reference' is selected as the genlock source.
Output
Format
Select which input video format should be used for the video
output.
Ancillary Data
Select which video input is the source of output ancillary
data.
Invert Output Key
Select this to invert the output key. Use this to match the key
polarity with other equipment or for monitoring purposes to
make the key more visible.
GPI Preset
Recall
Enable
Select to enable recall of presets by GPI. Presets 1-32 can be
selected from the binary coding of the external GPI inputs.
GPI Active Level
Select low or high level as the active level for the GPI
signals.
GPI Trigger
Select whether GPI recall should be triggered by a change in
level or a pulse.
GPI Fade Keys
Enable
Select to enable fading of keys by GPI.
GPI Active Level
Select low or high level as the active level for the GPI.
GPI Trigger
Select whether GPI triggering should be triggered by a
permanent change in level or a transition.
Board Reset
Defaults
Select to restore Safire 3 to default conditions without
erasing stored presets.
Erase Presets
Select to restore Safire 3 to default conditions AND erase
stored presets.
Timing
Frame Delays
FG/BG/Key Delay
These controls delay the selected video by up to ten frames
at the Safire 3's inputs.
Output Delay
FG Short Delay
Select this to disable the Noise Reduction and Edge
Softening filters to minimise propagation delay. Short Delay
for SD = 85uS, HD = 18uS, 3G = 10uS. Without Short Delay
selected, add 5 line delay to the above values.
FG/BG/Key Frame Delay Indicates whether the output signal is more than one whole
frame delayed with respect to each input.
Pixel Timing
Delay output video horizontally by 0 to 2640 pixels with
respect to reference. (See note below)
Line Timing
Delay output video vertically by 0 to 1125 lines with respect
to reference. See note above for max delay.
Note: the total
Pixel + Line delay can not exceed one frame for any output
standard. E.g. 720 lines is the maximum delay for 720p
standard.
