When the telecine is switched to Vari, another set of Runup and Slip
values are used.
Edits are setup in the same way as for 625 editing.
If another varispeed is used then the runup will need to be adjusted
again.
Only one set is saved for all varispeed settings.
In varispeed POGLE cannot always compensate for the inserted or ignored frames, consequently the edit points may move slightly from one edit to the next.
Vtr and audio transports are always run at fixed play speed. If audio must be synced, that was not recorded at video rate, then the audio transport must be locked to the film using bi-phase or timecode. Aaton and Evertz systems can produce the required timecode.
When performing an edit Pogle checks the durations on the telecine and
the vtr.
If they are different, then the Pogle automatically calculates the
correct varispeed for the film so that it will match the vtr duration.
Hit PERFORM again to continue with the edit.
If the Pogle sets the telecine into varispeed when performing, it will be because there are conflicting out points for the telecine and vtr.
If the tk outpoint is not correct, then CLEAR out of TRIM and DELETE the telecine OUT point.
Why does Pogle goes into TRIM and set the telecine to varispeed
when performing?
This is because both the telecine and the vtr have out points.
