Timecode Mystery

Hello all,

I think we did some good work on last week's YVH's but we still encountered the mysterious timecode problem which has been giving us trouble with audio and video synchronization. This has happened almost every time we have ingested video for the last two weeks and on various different machines. This leads me to believe that it is not a problem with the decks or computers but rather with the camera or mic or possibly with the tapes. I think some serious investigation is called for on this one. So, by way of starting the investigation I will exposit on every detail that may help yield a solution to this quandary.

The tapes play fine when in the deck, but when ingested we see either a warning message saying something like... "Timecode break encountered. Must re-log clips" or "A problem was encountered..."

I first noticed these issues after we began using a new mic. Although this seems unlikely to cause such a large discrepancy in synchronization (usually about 5 minutes).

The camera has displayed the words "Auto Shut-Off" several times during shooting, although not while recording luckily, and promptly shut down.

We have been shooting in 30f instead of 60i for the last couple weeks as well. I don't know if this could be a potential culprit but it coincided with the problems.

I think that's about all I have noticed but I will keep thinking. I will also do some online research and see if there are any similar stories out there.

  1. I think the problem might be occurring in FCP. Some times Final Cut likes to assume where the time-code begins and where it ends. It even trys to rewind and ff to achieve this. What I have learned is is you set the capture device to non-controllable device, you will never have these problems. Try that next time.
