I shot some video a week ago and just relized that when I would cut the camera off or change battery it would break the time code. Is there any way to fix this?

Yes, there's a very easy way. Just make sure that your last shot always rolls a few seconds longer than you really need (always a good practice). Then the next time you pick up the camera, use the "Rec Search Minus" button (located on the front panel just to the left of the aspect ratio selector switch). While in Record Pause mode, as you press the Rec Search Minus button, the tape transport will back up and you'll see the previous frames from your last recording. Release the button. The camera picks up the Time Code from the point. This process is a good habit to get into.

yeah I got it now, you just have to record for 5 or 10 seconds longer to have enough room. Thanks for your help.
