Using Frame Lock
Frame lock synchronizes the frame rate of the SDI output to an external synchronization
source.
When using frame lock, only modes that are valid for the frame rate of the sync source
can be used for the SDI output. The valid modes will appear in the Output Video
Format list.

NVIDIA Genlock supports the following external synchronization signal types:


Composite Bi-level (NTSC or PAL sources use bi-level composite signals.)

