I've been meaning to post this for a while. I'm sure quite a few FCP users have toyed with JES deinterlacer to slow down 60i into 24pa. Here's some slowmo I did with it on this clip, along with a tutorial.

Please don't bother critiquing the vid - I hate so many things about it, and in some places I didn't use JES (the strobing slowmo sections). JES is free from the web.

PLEASE SAVE AS

Take the 60i footage, and bring it into JES deinterlacer. That made the 60i into 60p, hence doubling the movies duration (there is an option where you specifically choose 'double duration').

Then I took that into quicktime pro, and exported as image sequence. Then I reimported it back in to quicktime as an image sequence, and chose frame rate of 23.96. QUicktime will prompt you to choose a frame rate.

Once that's done, save the movie as self contained (makes it huge, but stops you from relying on all those wretched image files). Delete the image files, and import your final slow mo movie into FCP, or your NLE.

Once in FCP I still had to render it, not sure why, but it finally sat happy on a 24pa timeline and looked great.

Anyway, here's the frigging movie after all that. Hope it helps someone....it's late!

when converting an image sequence to a qt movie using quicktime, set the compression as "dv ntsc" at 23.98 fps. that should solve your having to render in FCP problem. do not confuse this with dv stream. streams have to be rendered. just a regular QT movie with the .mov extension is what you need.
 
slowmo looks great. i haven't ever tried the 60i thing. i do 30p sometimes and do the image sequence bit to get it down to 24p. but that method only gives you slight slomo. does the video still retain any of that 60i "video" look after deinterlacing? in other words, if i shot a piece at 24p but did my slomo shots at 60i, would the look match up well between the two?
 
Actually yeah, it shows no interlacing at all after this trick. Smooth as butter. I mean if you look REALLY hard of course you'll see some minor imperfection, but for fooling one's audience it does the trick nicely.
