Adjusting the Sync and Subcarrier Phases
When using two or more players, as in an A/B roll editing
system, it is necessary to synchronize the sync and
subcarrier (for composite signals) phases of the signals to
be edited. If they are not synchronized, picture instabilities
or color break-up may occur at edit points. After configuring the editing system, use a vectorscope to
adjust the sync and subcarrier phases of the recorder and
players. Subcarrier phase adjustment is necessary when
using composite signals and Y/C signals.
b) Ensure that the 75 Ω coaxial cables (A) and
(B) (not supplied) are of the same length.
