OPERATING THE 4025 WITH BARCODED FILM STOCK

OPERATION
the 4025 can be configured for AUTO rate detect. Changes in transfer
rates by the telecine operator are automatically detected when the telecine
is in still. The front panel PULL and 1:1 indicators will show the transfer
rate that has been detected.
Other telecines do not maintain coherent film frame pulse sequences in still
or shuttle modes. When used with these telecines, the 4025 must be
manually set to the correct transfer rate to accurately track the film /
timecode relationship.
24 FRMS / SEC manually selects a transfer rate of 24 (23.97) frames per
second. The front panel PULL LED should be on.
30 FRMS / SEC manually selects a transfer rate of 30 (29.97) frames per
second. The front panel 1:1 LED should be on.
Do not use AUTO rate detect with Rank Cintel URSA or BTS telecines. Do
not use AUTO rate detect when using a Time Logic Controller and Rank
Cintel 4:2:2 telecines.
In PAL the film rate is fixed at 25 FRMS / SEC.
