RS422 MASTER CONTROL OF NON-LINEAR VIDEO RECORDERS
Using the ‘RS422 only’ external timecode selection, it is possible to take full advantage of non-
linear hard disk video recorders such as the FED V-MOD 100.
When using any of the SMPTE+RS422 external timecode options, although locate/lock times in
this case are virtually immediate, when jogging at slow speeds, there is no significant performance
improvement over a VTR and the non-linear video recorder will ‘stutter’ frame by frame much like
a normal VTR. However, using the ‘RS422 only’ selection, slow speed jogging is exceptionally
smooth and very tightly locked to the Akai system’s audio jogging and so is ideal for spotting audio
to picture.
However, please note that because of inaccuracies in the timecode sent via RS422, when playing
at nominal speed, there may be instances where there is a
±
1 frame offset. This can be overcome
by switching to SMPTE+RS422 for playback and using RS422 only for jogging and spotting. Of
course, in the RS422 SETUP page, RS422 MODE must be set to MASTER and the ON-LINE key
must be switched to ON.
