Slow Motion and Regular Speed in One Shot (And a Final Cut/iDVD Possibility)

Here's a scenario. I want to be able to do a progressive shot which starts in regular speed, and at a specific moment, have it go into slow motion. For example, a person splashes a glass of wine into someone's face, and it starts at normal speed, then at the moment the liquid exits the glass, slow motion starts. 60p however at regular speed has a very "live" feel, pretty much like interlaced. So, is it possible to have a shot done in 60p, bring down the speed of the slo-mo part like you normally would, and somehow alter the first part of the shot so that it appears 24p?

Thank you for any help! It's appreciated very much!

Also another maybe dumb question---how can I edit in Final Cut and export the project to iDVD? Possible or impossible? I just am not familiar with DVD Studio and if I want to know if I can make a simple DVD this way if I need it quickly.
 
That's about the only way to do it -- shoot in 720/60p, then conform all the footage to 24fps. Then play back the "real time" stuff at 2.5x speed, and play back the "slow mo" stuff at 1x speed.
 
I just have to add in another question - What if the camera shoots using 720/50p? Do I confirm all footage to 24fps or it will also work for 25fps?

I'm using an HMC 152EN. Sometimes it gets confusing reading topics that have different formats to mine.
 
For a 50hz camera, yes you'd shoot at 720/50p, and conform to 25fps. Play back your "normal speed" footage at 2x speed, and your "slow mo" stuff at 1x speed.
 
Thanks Barry. It's a bit unfortunate though that there's no real way to conform 60p at 100% speed so that it has the feel of 24p ;(
 
There is a way to make 720p60 footage look like 24p. Use the Strobe filter in FCP and set the strobe duration to 2.5 (60/2.5=24). Doing so causes FCP to duplicate certain frames so that there are only 24 unique frames during any 1-second period.

Setting the strobe duration to 2.0 would produce 30 (60/2)unique frames every seconds.
