If the edit timing is incorrect the wrong source frame will appear at the IN point of the record deck
If the event timing is incorrect the colour corrector and noise reducer corrections will occur at the wrong timecode.
If the autoshot timing is incorrect the event will not be marked correctly.
In tape to tape operation, wih normal field 1 dominant material, the events should all appear with a *. This is because the data in each event lasts until the end of field 2.
Even if the problem only appears to be the timing of the grading corrections, it is also best to check the edit timing.
To setup timings connect a Player with source
material and a Recorder.
Ensure that the Player and Recorder both edit
correctly.
Use a vtr or disk that easily jogs field by field as the Recorder.
(Not an old D1)
If possible turn on the timecode burnt in display on the source
Player.
