Compensating for Film Delays Inside the Telecine
Use the Telecine Setup screen to set the Prestore delay.
PRESTORE DELAY Is used to adjust for film rate pre-store delays such
as film grain/noise reducers etc.
CLEARVIEW, enabled, or URSA DIAMONDS or BTS SPIRIT
telecines usually need a non-zero value of PRESTORE DELAY.
Otherwise use a PRESTORE DELAY of zero.
compensations affect the VITC, LTC and Character Generator
outputs. Press the $ & % keys to change the value. Selecting
00 frames turns off the prestore delay compensation.
The PRESTORE DELAY parameter compensates for delays
that occur inside the telecine prior to the image being converted
to video - while the VIDEO DELAY compensates for any
downstream delays in the system which occur after the image
has been converted to video.
The PRESTORE DELAY value does not affect the correct
alignment of the pulldown of the burn-in film number display to
the pulldown of the pictures - it simply affects the matching of
the numerical frame number to the picture frame being
displayed.
VIDEO DELAY will affect alignment of the pulldown of the burn-
in displays to the pulldown of the pictures, and will also affect
the numerical matching of frames. Hence, it is important to get
the VIDEO DELAY setting correct, before attempting to alter the
PRESTORE DELAY.
The HARDWARE menu of the Toolbox menu is used to configure various
hardware related items of the 4025TR such as character width, display
brightness, Telecine Type, Biphase Rate, etc. Press SHIFT+SETUP to
enter the Toolbox menu system. See section 3.2.1 for an overview of the
Toolbox menu system.
