1080 over 60i slow motion?

Greetings!

This question may have been asked in previous postings; however, I have not been able to find a suitable answer.

situation:

I want to shoot 1080i60 to drop into a 720pn24 (HVX-200) timeline to create slow motion video. The reasoning behind shooting 1080i is to be able to smooth out bumpy footage without degrading image quality. I understand that in order to get in-camera slow motion, one must be in 720pn24 and change the frame rate accordingly (48fps would give you 50% playback speed). I suppose what is really not understood here is the trade-off (or difference in quality) between de-interlaced, "smooth-cam'd" 1080i60 to 720p24 and "smooth-cam'd" 720pn24 shot at 60fps. Would it look worse- to stretch the 720p video for smooth-cam, or to de-interlace 1080i and down-rez to 720?

I know the question above is quite convoluted, but I don't know how else to put it.. Has anyone else gained experience in this area? And seriously, any constructive input is greatly appreciated.


Much thanks,

I guess you mean converting 24fps footage to 60 then slowing it down. Yea, that would look worse, because you never had the temporal resolution to start with. 1080i60 is better. You will deinterlace the footage to 60p, then slow it down to 24. Stu Maschwitz mentioned this in his DV rebels guide.

You can use my G Map Frames (In standards Conversion Pack) plugin to do this - it extracts out the fields so going from 60i in a 24p timeline gives a nice 2.5x slowdown (40% speed).
