Check with the telecine house, and the colorist in particular. I find it impossible to believe they didn’t generate any files or printouts. Maybe the files just didn’t get delivered with your tapes, that’s happened to me. Without it, you’re seriously screwed. You’ll have a 1 in 3 chance every time you digitze of getting it right, so that’s gonna take some time. You’ve got no record of the pulldown cadence, so more trial and error to get a proper reverse telecine. Also, the potential for error when hand entering the key numbers is enormous. And you’ve got no way to double check the colorist’s work. Somenone who would forget to make a flex file is likely to have made other mistakes, such as allowing the key numbers from one camera roll to continue into the next roll. This is a not uncommon problem with lazy telecine operators. DI time is really expensive, and eye matching at that point is gonna be very time consuming.
