Timecode Source
Choose between a separate-channel Longitudinal Timecode (LTC) or Vertical Interval
Timecode (VITC) transported in the video signal’s vertical interval or include both (LTC + VITC).
Click on the Hot Text items to enter a value for:
•
Preroll – 0 to 15; the number of frames required to start the source machine before
capture
•
Handles – 0 to 60; the number of frames added to the front and back of a sequence for
editing flexibility
•
Timecode Offset– -30 to +30; timecode adjustment (in frames) forward or back to
compensate for discrepancies between the source’s burned-in timecode and that of the
captured sequence.
General Options
Video/Audio Directory Setup
Use these hot text fields to enter the path of the default
capture/playback directories.
Enforce Memory Alignment
For almost all cases this checkbox should remain
unchecked. However on certain types of RAID Controllers
(usually RAID5 SATA), when reading or writing to disc,
to or from system memory, memory alignment must be
done on a 512-byte address alignment. Enabling this
option insures that reading/writing is done to a 512-byte
address in system memory. But there is a performance
cost. Due to re-alignment, reading/writing is not
guaranteed to be in realtime.
Audio Files Setup
Three audio enable check boxes, when checked, allow you
to:
•
Enable Audio Scrubbing – Audio will play while you move through frames using the
scrub bar (see Play Controls).
•
Enable Audio Variable Speed – Audio will play at the same speed the video is played
(rather than 1x only).
•
Enable Audio Auto-Search – KONA software will automatically load the Audio Track list
with audio files that have been generated with the same name as the selected video file.
Note: When Audio Auto-Search is active, existing file names in the list will be removed or
over-written when the Video File is loaded. (Does not affect the actual audio files.)
Audio Monitor Levels
Choose between +6 dB (US) monitor level and +0 dB (EBU).
