Camera Data

32.0 LOSS OF VIDEO

Ki Pro Rack v4.2
For the RED One, timecode should be sent to the camera via a timecode generator in
order to produce corresponding timecode recordings on the
with this configuration, the timecode value produced has an accuracy of +/- 1 frame. RED
One firmware version 31.6.16 (or later) is required for proper operation.
Because the Camera Data parameter requires the use of SDI, only the XF series cameras
that feature SDI outputs can be used with this feature. These cameras provide ancillary
data that produces start/stop commands and timecode values but not clip naming.
These cameras provide ancillary data that produces start/stop commands and timecode
values but not clip naming. The Canon EOS C300 outputs 1080i by default, but can
produce true progressive video within this interlaced output. The extraction of 1080p
23.98 from within 1080i 29.97 and 1080p 24 from within 1080i 30 is automatic if the
camera is properly configured and the Camera Data selection is set to Canon C300; users
do not need to manually set the Record Type parameter separately. However, for 1080p
25 that is output as 1080i 25 and 1080p 29.97 that is output as 1080i 29.97 from the
camera, users need to manually select "PsF" in the Record Type (1.1) menu parameter
even if they have selected the Canon C300 in the Camera Data parameter. This selection
is required because there is no ancillary data indicating these frame rates within the SDI
output of the camera.
In order to configure certain menu parameters on the Canon HDMI cameras, the HDMI
cable must not be connected to the camera. Configure the camera's HDMI settings prior
to connecting the HDMI output of the camera to the Ki Pro Rack. Since the Canon HDMI
selection is not camera specific like the other Camera Data selections, other parameters
must be set manually and are not auto-configured by this selection.
For use with the C100, the following CONFIG menu parameters should be set as follows:
1.1 Record Type > VFR (if the C100 is configured for 2-3 Pulldown on the HDMI
output
2.1 Video Input > HDMI
2.2 Audio Input > HDMI
8.0 TC In > HDMI.
Ki Pro Rack does not provide support for VFR recordings when the DNxHD encoding
mode is used, so some of the functionality of the 13.1 Camera Data is not supported
when DNxHD is selected. While camera start/stop and timecode values may be produced
when a Camera Data selection is made, frame extraction from RED or Canon cameras is
not supported. Users should consider using ProRes encoding if the Camera Data
capabilities are desired. Note that Apple ProRes QuickTime files may be used with Avid
Media Composer via AMA.
This parameter selects whether recording continues when valid video is not present.
These are the available options:
STOP Rec(default)
CONT Rec
NOTE: If CONT Rec is selected, and a loss of video is encountered, a graphic with the text "LOSS OF
VIDEO" superimposed over color bars will appear. Be sure to check your source and video
connections if you are experiencing a loss of video.
Recording stops when video is lost
Recording continues when video is lost
