Guys…
ALL Digibeta editing decks have the ability to simply insert new time code information using a simple insert edit. Just set your starting code, do an insert on the time code track only and you will be good to go. The only problem here is if your original tape does not have a continuous control track. Then you will have problems.
If you have another Digibeta deck available, the best solution is probably to simply “clone” your tape to another tape. This will be a digital transfer to another machine resulting in a continuous time code track and control track with no loss in quality. If you have just a tape or two, and don’t have two decks at your disposal, it might be a good idea to simply send these off to a dub house for the duping.
As for adding a little “heads” and “tails” to each shot in the field, while not strictly necessary for preroll purposes, it is just a good habit to get into. Tape is cheap. Production time isn’t. Which would you rather pay for?
