replaced regex for turning list of matched frames -> start, end frames.
Replaced by the frame matching logic having the frames just keep track of their own number.
This should result in far fewer errors, and a marginal speedup
Issues
the regex used to take the matched frames and turn them into start and end frames was buggy and often resulted in the wrong start time.
Notes
sorry for all the edits. There was some weirdness with comparing branches
