Missing Time Code: not so excellent at DVinfo.net

Tom Koerner · April 8th, 2005, 12:10 PM

I am currently working on two short films; I'm editing one and DPing another. Both are using a DVX 100A. I have no problem capturing the footage onto my G5 with my Panni GS-200 from the one; but for the one I'm actually editing, the tapes don't register Time Code on my camera. The hardcore decks at the lab I work at registers the TC fine.

The only difference I know of is that the tapes I can't read timecode on are Sony Excellence instead of Sony Premiums. Is that a potential cause or is it likely some camera setting? I'm betting this is the best thread, if not please chastise me.

Were the tapes recorded LP mode by any chance?

The grade of tape is almost surely not a factor, though when things go wrong, who knows ...

The best solution is likely a Firewire dub of the problematic tapes -- the new tapes will have exactly the same video/audio data, but with a new timecode track laid down by the recording device. Make the dubs now, before you are deep in the edit process, and treat the dubs as if they are the camera originals ...

The joys of lossless dubbing!

Lossless dubs - astounding! That should do it for sure. You, sir, are a gentleman and a scholar.

On the note of the actual problem - the production shot this weekend on standard sony premium - so i will soon know whether that had any bearing on the recognition of TimeCode. Stay tuned - same bat thread, same bat forum.

I vote for the LP possibility also.

The LP was a juicy possibility - but alas it was not to be. That isn't the issue. The plot thickens, however; as I noticed that my camera registers the minutes left on the tape - but not the time code.

We are getting some regular sony premiums they will be shooting on soon - so I will be able to let you all know if tape quality could conceivably affect time code availability.

What do you mean by 'registers the minutes left on the tape'?

The camcorder's convenience display of 'minutes left on tape' isn't a timecode function -- it works with blank tape that has nothing recorded on it, as well as used tape.

Recorded to tape is the timecode track, which counts up from 00;00;00;00 unless forced to do otherwise, the date/time track which records the date and time of day to the second but not frame _if_ the date/time clock was set on the camcorder before shooting (set once, lasts until the button battery runs out), and the data track which records details like shutter speed, iris, gain & white balance details if your camcorder supports this ...

On some devices you can set the start timecode to other than 00;00;00;00 or you can choose 'Free run' instead of 'Rec run' (which leaves the timecode clock running between shots, so any camcorder pause creates a 'jump' in the timecode track.

But the 'minutes left on cassette' feature is not part of any of those, and was available even on VHS and Hi8 devices that didn't offer timecode.
