SMPTE Configuration
Next, we will setup the SMPTE interface in the SMPTE
Configuration screen. You can access this screen by selecting
Binloop SMPTE Configuration… or by clicking on the
icon.
For consistency, we want the SMPTE clock to run at exactly the
same rate as the video. We will be playing 29.97FPS video in
this example, so select
29.97 as the frame rate and enable the
Genlock To Video option. We also want the SMPTE generator
to Start Automatically on Power Up and Loop SMPTE at End
Time , so make sure those options are enabled as well.
Now, the only thing left to configure is the range of time that the
SMPTE interface will generate. First, set the
Preroll Time to
00:59:55.00 and the Start Time to 01:00:00.00 . For this
example, the End Time value needs to coincide with the end of
the video. If you loaded the test clip mentioned in the Playing a
Test Video
section, the length of the video is 2 minutes and 39
seconds (or 00:02:39.00). One might conclude that the End
Time would then be 01:02:39.00, but not so fast! The
reproducers are not capable of playing video immediately when
they are commanded to do so. They need time to load the video
before playback can actually begin, so there is a consistent delay
associated with the Play command. This delay is exactly 2
seconds. When you add this delay to the video length, you end
up with an
End Time of 01:02:41.00 . After that, click OK to exit
this screen.
