CLOCKWORKS

Turning off Frame lock can be a life saver if you find
yourself in a situation where you have time code on tape
(or other source) but the frame locations jump around to
different times (because of overlapping SMPTE striping,
edits, or whatever). By turning off Frame lock, you can
sync continuously to this type of time code without
glitching or stopping. If the SMPTE on your tape jumps
around as described, you are likely to experience brief
drop-outs at the points where it jumps. If so, just increase
your MOTU interface’s freewheeling to cruise past them.
Generate signal when stopped
This option applies to situations in which your MOTU
interface is converting time code and the source time code
continues even when it is parked on a frame. The most
common case is when your MOTU interface is locked to
SMPTE time code being generated from a VITC converter
that generates time code while still-framed (such as a
MOTU Digital Timepiece universal synchronizer), and
the video deck is paused. In this situation, the Generate
signal when stopped option, when checked, makes your
MOTU interface continues to output time code (LTC,
MTC and VITC), even while the video is parked on a
single frame in pause mode. It will continue to do so as
long as the video head is engaged and VITC lines can be
scanned.
Auto-detect input frame rate
When this option is checked, the MIDI interface will
automatically detect the frame rate of incoming time code
(LTC or MTC). In most situations, this is desirable because
it ensures that your MOTU interface is properly
interpreting and synchronizing to the time code. If,
however, you find yourself in a situation where you would
like to set the frame rate manually, uncheck this option
and set the frame rate in ClockWorks.
LTC Outpu t
This slider allows you to adjust the overall gain of the time
code from your MOTU interface LTC output jack. Move it
towards the left to reduce the level; move it towards the
right to increase it. This level control affects LTC output in
all sync modes, including LTC, MTC, etc.
