CinePlex v3 Manual - Plexon Inc

Note that applying this correction can shift Markers to have a negative timestamp
near the beginning of files. When this happens, the timestamps will be assigned
the value of 0.
In addition to the correcting for the camera latency, an independent correction for
the tracking latency can be applied, as discussed in the next section.

Note:
As of CinePlex Editor version 1.2.0, these latency corrections are now enabled
by default, with a default correction of 21 milliseconds. If data have been analyzed
using previous versions of CinePlex Editor, the timestamp shifts after
upgrading to version 1.2.0. To return to pre-version-1.2.0 behavior, one can disable
the corrections by unchecking the checkboxes.
When CinePlex is being used with Plexon’s Recorder system, there was an
issue with Recorder versions prior to 2.3.2 that could artificially increase this
latency by up to 80 milliseconds. If using CinePlex with Recorder, please
upgrade the version of Recorder to version 2.3.2 or later. Also, use a video
latency correction of 33 milliseconds as discussed above.
When CinePlex is being used with Plexon’s MAP system, leaving the MAP on
overnight could result in excessive latency - much greater than 30 milliseconds.
If the MAP has been left on overnight, it is better to reset the MAP system.
