Sony SVO-5800 Operating Instructions Manual page 33

When using two or more players, as in an A/B roll editing system, phase
synchronization of the signals (i.e., system sync) is necessary. For composite
signals only, the subcarrier phase must also be in synchronization. If not, picture
instabilities or color break-up may occur at edit points.
The FXE-100/100P video editing system and a switcher with built-in frame
synchronizer, such as the DFS-500/SO0P, automatically adjust the sync and
subcarrier phases. For other switchers, after configurating the editing system, use a
vectorscope to adjust the sync and subcarrier phases of the recorder and players.
Subcarrier phase adjustment is necessary only when using composite signals.
