Questions about bringing 60i into 24P timeline for slowdown...

I was reading in the DVXbook about doing slowmo.
It recommended shooting in 60i at 120 shutter speed, and bringing it into a 24P timeline (23.97), then slowing down to 40%. Is that really all you need to do? I gave it a shot with some interesting results.

There is interlacing all over the place in Adobe Premiere, and I'm assuming that because of the way that it is done there is nothing you can do to fix that correct? If i export with Adobe Media Encoder and click the Deinterlace button, it comes out without any interlacing. The video did look a little weird and jittery a few times, yet the book recommended it should be glass smooth. The slowmo is nice, but the video just doesn't come out perfect.

Now if I export it outside of Adobe Media Encoder, I get the interlacing because there is no De-interlance button. Is this normal? Will there always be interlacing bringing a 60i into a 24P timeline? Do you have to edit with all the interlacing then deinterlace with another program afterwards? Barry's guide seems to make it sound like it should come out perfect.


Also, if I want to use 60i footage on a 60i timeline, I'm assuming that I'm bringing it on 29.97 frames per second timeline, correct?

Thanks in advance.

Just wondering if you ever got an answer to your post. I'm having the same problem. I followed Barry's instructions in The DVX Book, and shot at 60i, 1/120 shutter speed, then brought the footage into a 24p Final Cut Pro timeline (I tried various capture settings in FCP). Result: Lots of ugly interlacing and no real sense of slow motion.

I've been searching the dvxuser site looking for an answer, but haven't found one yet.
 
I checked out the above article...but can't figure part of it out. How can I do this in FCP?

Interpret Footage
This is a very important step! Conform the frame rate of your clip to 24 frames per second, then set "Separate Fields" to "Lower Field First." NOTE: Some third-party plug-ins for After Effects handle the field interpolation themselves, in which case you would not have After Effects separate the fields. The plug-in would take care of this.
