Normal speed clip to slow motion

I'm posting this in the cinematography forum too because I have a feeling this has both to do with shooting and post.

I'll be shooting some football footage and want create a final clip that goes from normal speed to slow motion without a cut or transition, just a seamless movement. HBO's Hard Knocks uses this effect a lot, that's the only show I can think of as a reference. What I'm seeking is just how to do to this. I'm assuming I need to shoot the footage overcranked. I'll be using an HPX-500 which I know can shoot at 60p overcranked. When I get to post do I speed up the clip to play at normal speed then slow it back down to play at the overcranked speed? I'll be playing the clip back at either 24p or 30p; which ever looks best. And I'm working in Avid Media Composer 4.0.

Any suggestions or changes would be greatly appreciated.

Sounds about right to me. The editing term is "Speed Ramping", based on how the timing curve looks in the editor.

The overcrank will give you a cleaner slo-mo than normal fps.

You'll like the speed ramp effect in MC.

I'm using Final Cut Studio 2 and recently worked with quite a few pieces of 50p footage in a 25p timeline [we're in PAL land].

What I found is that dropping the 50p footage in the 25p timeline and slowing it down does not give me clean footage. The way which worked was to conform in Cinema Tools [surprised by how quick and easy it was - but if you haven't done it before, do note that it changes the original clip instantly - so remember to keep a copy of your raw footage somewhere].

The slowed down footage will then play cleanly in the 25p timeline - and I could speed it up to normal with a 200% speed change.

Not being familiar with AVID, could you just drag and drop - and it'll play nice?
