System information

MX Control
4-8 Vicon MX Hardware System Reference
where:
hh =hours (00-23)
mm =minutes (00-59)
ss =seconds (00-59)
ff =frames (00-24 for PAL/SECAM, 00-29 for NTSC)
For NTSC, the separator character changes between a colon (:) for
non-drop frames and a semicolon (;) for drop frames.
Vicon MX reads the sequential timecode along with video, audio, and
Vicon raw (X2D) data, which you can use to locate a precise reference
point for editing your data. This timecode information also can be
used to synchronize Vicon MX with external recording equipment.
Timecode Triggering
From the Vicon software on the host PC, you can configure Timecode
triggering to automatically have the MX Control start and/or stop data
capture based on the timecode.
This is useful, for example, if your application uses a background plate
(film scene) that requires a specific movement of a computer-
generated character to be accurately timed relative to that plate. You
can set the data capture start time to the same timecode as the plate’s
Action time and trigger the capture process. The MX Control then
starts the capture when the specified timecode is reached.
Frame Count
The MX Control generates a frame count for each frame of data
Vicon MX captures during a trial. You can use this frame count to
locate a precise reference point in your captured data. The MX Control
resets its internal frame counter to zero at the start of each trial
capture and increments the count for each captured frame.
Video Burn-in Window
From the Vicon software on the host PC, you can configure the Video
Burn-in Window to embed a display of either the current timecode or
frame count into the video output signal. The MX Control reads the

timecode generator for Vicon MX and other devices, it generates LTC
or VITC timecode (you can set the current timecode in the Vicon
software). In either case, it can generate its own frame count.
