BIPHASE ACCURACY TEST

The biphase accuracy test allows you to verify that you have compensated correctly for the system
delays in the telecine and the video delays between the output of the telecine and the input of the
9025TR. (Colour corrector and noise reducer delays typically)
connections, you may proceed to the KeyKode reader installation.
If you do not verify the frame accuracy of the system at this time, the accuracy of
your system with KeyKode will also be affected.
The following simple procedure will help you establish that the 9025TR is properly installed, and that it
is configured correctly for your application.
1.
Make note of the key number on a piece of reference film. This number is usually the Key
number of the frame where a reference KeyKode dot is located (i.e. on the whole foot
mark). Mark this reference frame with a punch or grease pencil.
2. Place this film on the telecine, with the reference frame in the gate.
3. If you have already set up the Telecine Parameters and sent the configuration to the
hardware as described in section 3.1 and 3.2 you can proceed to step 4.
a) Open the KeyLog TRACKER™ Telecine Setup screen from the Edit menu, and select
the System Default Telecine Setup.
System Default Telecine Setup. Set the Video Delay parameter to match the path delay
(in video fields) between the telecine output and the 9025TR input.
b) Open the System Configuration screen from the Edit menu and then open the System
Default Configuration called Biphase Accuracy test for the video standard you are using.
You will be prompted to make a copy so click Okay. Give the new configuration a
suitable name such as 'Engineering Test'. Make sure that the telecine tab parameters
match those of the System Default Telecine Setup. Press the Okay button to send the
configuration to the 9025TR. It will place the hardware in the correct mode to perform
the following test. Close the System Configuration screen. (See the section titled "First
Time Setup" in the KeyLog TRACKER™ manual or online help for detailed information).
c) Open the Encoder Status window using the
