Uncompressed WAVs and WMM

All right, so I've got all my raw materials together and I'm reading through the guide to getting nice accurate uncompressed WAVs through EAC and setting them up for ease of editing. All of which was fine up until I got to the point where it said that I would need to mess around with framerates if I was going to be editing in Premiere, since it can't handle 23.976, and that my audio would have to be sped up accordingly.

Now I don't have Premiere, but I'm wondering if the same problem applies to WMM? Do I need to worry about changing the framerates of my audio to fit with WMM's preferred speed? And if I do need to change them, how do I change them? I noticed that BeSweet has a nice setting already up there for Premiere's 24fps, but I didn't spot one for WMM.

Now I hope I'm just worrying about nothing and that WMM can edit in 23.976 and that everything will be fine, but knowing technical stuff I figured it was worth an ask first. Anyone help me out?

The good news is that you don't need to edit your audio.

The bad news is that this is because Windows Movie Maker always uses a frame rate of 29.97. But it's not really a big deal if you've IVTCed your source; you'll just get duplicate frames in the export, nothing big.

Thanks Scintilla! Being absolutely brand new to all this, I'm not quite sure what you mean by duplicate frames or how to deal with them, but I'll handle that issue when the time comes. *g* I'm just glad it's only the video I have to mess around with, not the audio too.

in every cycle of five frames, at least one frame will be an exact copy of another. wmm resamples the video, but at a higher rate than 23.976 fps, so this shouldn't cause any significant change in playback.

the only drawback is that the framerate of your video file is 29.97 fps, but only 23.976 "images" per second are being shown, which translates to a larger filesize than a 23.976 fps video of same visual quality.
