I was on a commercial shoot the last couple days. Cameras were 2 x Canon C300's that I had synced using Zaxcom ERXT's. I checked them periodically throughout the days for sync. On the last shot series of the second day I noticed one of the camera's timecode was off by a few seconds! I soon discovered that the timecode BNC cable (a locking connection) was now magically plugged into the genlock BNC connection. I plugged it back into the correct connector, timecode instantly synced and we finished the day.
As I was driving a PA home from the out-of-town shoot, I asked him if he had any clue what might have happened. It turned out that he had been instructed to unplug the video VTR cable (also BNC) when the camera was moved and had accidentally unplugged my timecode connection and obviously plugged it back into the wrong connector.
My question is how exactly would you proceed from here in terms of alerting/explaining to production what happened? We also were using a smart slate, and thanks to the wizardry of Zaxcom, we also had a mono scratch track of audio going to each camera. I get no pleasure in "ratting" anyone out (and this PA had been otherwise helpful throughout the production), but obviously at times out professional reputation is on the line. Clearly production must be alerted, but the question is how and in what words?
Thanks in advance for any level-headed input, as things like this are apt to make my head a bit un-level:)
Best,
Steve
