remastering old work, possible to change old frame rate?

I'm working to remaster some of my older videos. the ones I have in mind to start soon should not take much effort, but I'm trying to decide how to go about it.

the old videos were never IVTC'd or deinterlaced, and are thus 29.97fps avi files. since I will be using 24fps clean footage to remaster them, is it possible to change the frame rate of my old videos so that I can use them are referrence? in other words, can I put an amv that is 29.97 through avisynth to create a 24fps video to work off of when lining up scenes and making sure all my cuts match the original?

if I can, I'm thinking that I would do that, then insert it into my new premiere project, which would speed up the process of remastering the video by allowing me to compare frame for frame the old footage and the new. then I would just remove that file and keep the new footage to render the remastered copy.

or is that just a pipe dream, and I'll have to do it the old fashioned way by keeping the old file open in WMP and just doing my best to line up the clips to the same spots in the music? I can do it that way, as I did with Hands Down when I redid that one, but it takes a lot of extra time, imo.

Unless I'm mistaken, you should just be able to throw the 29.97 fps file into Premiere anyways.

hm... but wouldn't it then be longer than the song since the premiere project will be set at 24fps?

Premiere imports videos according to the running time, not the framerate. So it should automatically adjust the framerate of the video if it differs from the project framerate. At least, i *think* it does.

Er, last I checked, running time was calculated from framerate...

Well, yes, running time is calculated from the framerate and the number of frames in the video. But what I meant was, if the video is supposed to be 4 minutes long, it should still be 4 minutes long after you import it into premiere.

So what you're saying is that Premiere forces a video into the project framerate by adding or (in this case) dropping frames, right?

Yes, I'm saying I *think* it does that.
Premiere pro added this frame blending stuff (like vegas does) so it might blend frames instead of just dropping them.

Ahh, blended frames... the most recent bane of my existence...
