Just go through your tape and mark in/out each clip with enough heads on the incoming mark to be a bit more than your preroll. Most of the time you can get away with a 2-3 second preroll. Go through the entire tape logging the clips. After that, go and do a batch capture of the clips on the tape. With a little luck it will be pretty much automatic at this point. When you are finished, you will have a bin with the captured clips in it and timecode that matches the original code on the tape.
If there are timecode breaks throughout the tape, you cannon just capture the entire tape at once, but you can use the Uncontrolled Device preset to capture the entire tape using the Capture Now command, but the resulting timecode on the clip will have no relationship to the timecodes on the original tape. If matching timecode isn’t an issue, this way should still work.
Not my monkeys. Not my circus.
