Open the media clip in QT player and hit Apple-I. This will tell you what the what the framerate, compressor, resolution, etc. is. You said they added telecine and that the footage is interlaced, so my assumption is that it’s regular 29.97 NTSC.
The way telecine works is that the footage is slowed down by a negligable amount to make 24fps into 23.98fps. It is then transferred to 29.97 video by a proecss known as 3:2 pulldown. In order to get this footage back to 23.98, you need to determine the cadence and then perform a reverse telecine in Cinema Tools. And if you want to go back to actual film, you need to then conform it to a true 24fps by using a different tool within Cinema Tools. But talk to the film lab first and see what they need.
[eppdidit] “I refuse to use the de-interlacing filter because it makes the footage look like CRAP! There must be another solution.”
Actually it works very well when used properly on certain types of footage. For example, video-based 30fps footage shot on a digital format will usually deinterlace perfectly. But the filter is not meant to be used on 24fps based footage – which is why your footage looks like crap after using it. It isn’t meant to do a reverse telecine. There’s nothing inherently wrong with the filter so you should never feel you have to refuse it’s usage or make any negative quality judgements towards it. It just isn’t meant to be used with footage containing pulldown.
Again, you need a reverse telecine in Cinema Tools to bring it back to 24fps. There are also a bunch of filters from Nattress that may or may not be a better choice, depending on your situation. Since this is only one single video clip and the cadence has not been broken (I assume), just use Cinema Tools. But honestly, unless you have a lot of time to do a lot of reading and familiarize yourself with the subject of 3:2 pulldown and interlacing, I’d hire a lab to take care of this for you. Or just call the place that did the transfer and tell them you want 23.98fps Quicktime files – not NTSC. They may do it for free.
