Reference Output Timing
Genlock, also known as black burst, reference or house sync is used to lock various equipment in your
facility to the same timing point. When two or more video devices are connected to the same sync signal,
their video signals can be switched without jumping or rolling. This is critical when connecting equipment
in large post production facilities and broadcast stations.
To change video to reference timing:
1. Go to the Mac’s
System Preferences and click the Blackmagic Design icon.
2. Select the
Settings tab and adjust the Set reference output timing for timed output
until the picture locks and is no longer rolling on the display.
HDTV Up/Down Conversion
The software drivers included with DeckLink, can be used to downconvert high definition to NTSC or
PAL video in real time during capture or playback. They also provide upconversion on capture. Select the
desired option from the output or input processing menus under the Processing tab.
Output Processing
HD to SD Letterbox 16:9
HD to SD Anamorphic 16:9
720p HD to 1080i HD
Output Processing for DeckLink cards with simultaneous downconversion.
HD to HD and SD Letterbox 16:9
HD to HD and SD Anamorphic 16:9
HD to HD and SD Center Cut 4:3
Note: Simultaneous down conversion introduces a 2 frame delay on the SD-SDI output. To ensure accuracy,
adjust the playback/timecode offset options when performing an insert or assemble edit to tape with
Final Cut Pro, Premiere Pro or Blackmagic Deck Control.
Analog video outputs are also down converted so you can always see video on an S-Video or composite
analog monitor. Component analog video can be switched between HD or SD output. Choose to
Enable Conversion on Component, if you wish to view component analog standard definition video
output, when simultaneous down conversion is enabled.
