I just had a problem pop up that may or may not be associated with the Nuendo SMPTE generator plug in.
I used the plug in to create several SMPTE stripes for our video guys.
These stripes are 30fps. The wavs are 48/24.
Each stripe, once it starts, is continuous time.
I just got a report of three times where the SMPTE jumps out of time and then back over the course of about 3-5 frames. Although for the moment I can’t report down to the frame level, I’ll give you the actual times since they may be indicative of a problem:
hrs min secs
03 37 38
03 57 38
03 57 58
I’ve been told there have been other pops but I’m still waiting to get more times. The second and third times are in the same stripe, but the first time is in a separate stripe.
We were able to film the timecode and watch it back in slo-mo to see what was happening. For the first time listed above we saw the time code jump ahead to somewhere in hour 7 then back to hour 4 then it resumed as normal.
Has anyone seen anything like this before? The similarities in times regarding the numbers 3, 5, 7 and 8 seems very suspect to me. We have a SMPTE conditioner reading the SMPTE from Nuendo then resending it to the video playback system but, through testing, we’ve figured that the problem has to lie with either the Nuendo generator or the video system itself. Unless someone else has an idea of another culprit.
