Questions for video remaster

OK, I've got a couple of things I need to figure out before I get to work on remastering one of my older videos using DVD source this afternoon.

First off, I'll be editing the remaster in 24fps. But, the original video (which I have the file of) is in 30fps. I need to have the old video on the timeline in Premiere to be able to make sure I get my cuts to match up with the original ones, so I need to convert it from 30 to 24. What is the best way to do this? I assume I can't just import it into Premiere and toss it on the timeline (or can I?).

Second, once the remaster is done, I will need to convert the finished file back to 30(29.97)fps- I need to record it off to tape, and the highest-quality method I have of doing so is to make an SVCD and record a tape from the DVD player playing the SVCD. The guides (and posts in this forum) go into great length about IVTC, but I couldn't find much at all about telecining footage when a 30fps source from a 24fps edit is required. Is TMPGEnc's telecine good enough to just pull in the 24fps finished video, set it to SVCD settings, and hit 'Start'? Or would using avisynth to convert it to 30fps first be better? And if so, what would the likely best settings be? I really want the quality of this to be as good as possible (moreso than usual).

Thanks!

OK matching a 29.97fps video to a 24fps one is going to be tricky. Since you want the same timebase you can't slow it down to 24, the best thing you could do is decimate or drop frames down to 24. If it has a lot of quick effects this is gonna fuck you up good, but if you're just dealing with regular cuts and long static effects you'll be fine. You can do that simply in avisynth with changefps(24) if you have > v 2.05

As for playing back at 29.97. If you're going to put it on an svcd you can just hit "3:2 pulldown when playback" under Encode Mode in tmpg which will tell the DVD player to telecine on playback. That way you can still encode and burn it at 23.976fps and yet record it on vhs at the usual 29.97. You could also telecine it yourself in avisynth but I don't see why you'd want to when you can get your dvd player to do it for you :\

Sweet.

I think I can handle the losing a few frames. I know this video inside and out anyway, so I'll know where things need to be. Plus, I'll have the audio to sync to anyway if there's some confusion. My only slight concern is that I am using a slightly older version of the AMVApp on this computer (I've never had a time when I didn't have a project running, and I don't want to switch versions and possibly mess things up unless I can do it without the danger of messing with a work in progress). To do it without changefps, I would just use the same settings pretty much as if I were IVTC'ing a DVD from 30 to 24, right?

Being able to set the 3:2 pulldown is quite nice, I didn't know about that. I just wish that my progressive-scan Panny would play SVCDs and I didn't have to use my Apex for it :/

Thank you!

you could use Decimate() without Telecide() if you want to but I'd think changefps would probably be better :\ to check the version of avisynth just type version() in a blank script and open it in vdub and it should say. Like I said changefps works in any version greater than 2.05 (I think amvapp comes with 2.06)
