How to correct timecode in captured tape?
I have captured a tape in a native Adobe HDV project, around 60 minutes. This was captured as one clip, since PP does not support scene detection. Not so much of a problem by itself, although scene detection makes editing a lot easier. So, I have one clip and PP shows a continuous time code from 0 to the end.
BUT, and here is my problem, the tape has several time code breaks and I have been given a list of in/out points based on the time codes as the camera displays them. For instance IN at 00:24:30:24 and out at 00:25:26:00. However, the captured clip shows a time code in the source monitor where this IN point is 00:28:29:13
My question is: How can I correct the time code to display the same figures I have been given, in other words, can I offset the time code to correct the time code breaks on the original tape. That would be far easier than calculating the correct in and out point by hand.
Any suggestions? TIA.

Actually, PP2 does have scene recognition, but the camera clock must be set accurately, and turned on, so that when the camera is paused, Premiere will recognize discrete clips based on date/time. (see “About timecode” in the help utility”). For the future you could “stripe” the tape in the begining, i.e. record black onto the tape, that will help avoid broken time code.) Some record rooms used to be able to restripe a tape with broken code, but that’s not your problem at the moment.)
One suggestion that comes to mind would be to sit for the hour of tape, and create separate clips each time there is a break. When you see and note that the time code has shifted, exit capture, save the clip with a discrete name and continue and restart from where the time code was broken to the end of the break. You could go through the whole tape that way ending up with say 4 or 5 clips with the original time code, rather than continuous code. I also believe you can reset a individual clip time code by going to file–>timecode. I’ve never done that, but there are lots of suggestions in the help file with Premiere 2.

Bill,
Thanks for your help and suggestions. However, in HDV mode there is no scene detection, that only applies to DV. This tape was shot by a first time user of the Z1 and he must have been experimenting with the camera and probably was not aware of the end-search capability.
In a DV world your suggestion makes perfect sense, but in a HDV environment with MPEG2 encoding, frame accurate capture is not possible with PP. Even when using time interval batch capture mode, capturing let’s say 10 minute segments of the tape, consecutive parts have different end/begin points, often overlapping or missing several frames.
Unfortunately the Help file was no help and the timecode filter only allows an offset of 50 frames and can not be applied to the source monitor.
Any other approaches?

What I have done in the past with the ‘broken timecode’ problem was to create a sequence for each part of the tape where the break had occured and set the sequence start timecode to reflect the true timecode of that portion. Then its just a matter of cut and paste from the individual sequences into the main. Does that make sense?

Great tip, Baz. Thanks.
