Troubleshooting Tips

"Latent Images" or "Flashing" during
playback
❏
Incorrect source timecode provided or improperly closed
encoding session. If the incorrect timecode for a file on tape
is given, it is possible to encode a frame or two of trailer or
header information from the tape. Often this “extra” frame
may be seen only briefly and may appear as a visual "flash"
on the screen during looping playback. Review the original
source material and determine if the timecode are correct
for the tape, or if the encoding session was actually started
and closed on the correct frames.
SMPTE time codes are not recognized
properly
❏
Some SMPTE tracks lose information during compression
and may not “trigger” events as required. Testing is
essential to account for variances in encoders and SMPTE
devices involved.
NOTE
Harmony 4E series boards may not be mixed with
earlier generation Harmony or ReelTime series
boards.
NOTE
Timecode is the current playback position, in units of
90000 per second.
