Why does an edit fail with the message TK early
or TK late?
Adjusting the slip will simply hide the problem.
The telecine is probably early or late relative to the edit IN point.
Set Check Tk sync to Rough and
perform the edit. Check the film frame at the edit In point.
If the film is early then the required frame will not be recorded.
If the film is late then the required frame will appear after the In
point.
Repeat the edit again. If it is always consistently wrong, then simply setup the telecine again.
If it varies, then check these items, starting with the pulses in the
Source setup panel.
Philips BTS Quadra, FDL90 and FDL60.
Set the switches on the inside right of the machine to 30fps and TC.
Do this for all editing in 625 or 525.
The 6Hz pulse is required in 525 and HDTV to ensure accurate 2:3
editing.
Select 30fps varispeed to get a locked 29.97 playback. Using 29.97 will
be unlocked.
Spirit
Runup will be inconsistent with 50mm film cores. Always use 75mm cores.
The CFR pulse is required in 525 and HDTV to ensure accurate 2:3
editing.
CReality
The CReality internal film frame counters can get out of step. When
this happens Pogle will not be able to cue the machine correctly. If
this happens then can be resynced by the following Pogle keystrokes.
+0 PRESET COUNTER ENTER
However in this situation the film counter should also be checked against a known scene change.
Cintel Ursa and MKIII
Set the digiscan store to MASTER mode, field 1. The store freeze on run
option must be disabled. The telecine runup time should be set on the
machine so that a consistant startup is achieved. The picture should
frame in the same direction each time it runs. The runup does not need
to be 70ms, it can and should be set slower (> 100ms) particularly
if problems are found in achieving the required consistancy. If
problems appear at different points in large reels, then the telecine
should be setup again, starting with the spooling servo.
The Frame pulse is required in 525 and HDTVto ensure accurate 2:3
editing.
The capstan should be cleaned whenever the film is changed to ensure correct film handling.
If the acceleration characteristics of the telecine should change, then the Runup and Slip can be temporarily adjusted until the mechanics can be put right...by cleaning the capstan or altering the runup pot on a Cintel telecine. However if on edge the telecine must be adjusted.
If a frame of video delay is added or subtracted from the signal path, the telecine settings will need to be re-adjusted. It is strongly recommended that the video path delay be kept constant.
