Which mode would you shoot and why?
Football sports highlight - 720p60p or 720p30pn?

Custom Title!
I'd go 60P for that fluid look and you could always slow it down to 30 frames for some nice slow motion

But can you do this for fluid slow motion? Does Blu-Ray support 60p/60p playback?
How its 60p different than 60i (besides interlacing)
Or, what if I am going to DVD, and downrezzing to 480i30p... would everything be in slow motion?
60p - how is shooting this faster rate different than changing to a faster shutter speed? Would it make it look video-ish? I try and do my sports highlights more cinematic-like rather than live-action TV like.

Great idea!! A couple questions:
1.) When I shoot 60p (over 60), at a 180 degree shutter... that is 1/120 shutter speed, correct? So, if I conform this footage to 29.97 (30p) it becomes SLOW-MOTION, the exact equivalent of shooting 720p30pn @ 60fps w/180 degree shutter - is this correct?
2.) If I conform that 60p over 60 footage to 29.97 and then speed it up by 200% in a 30p timeline, will that give me the same effect as 720p30pn footage that was shutter with a shutter of 1/120 (instead of the default 1/60, which is equivalent to 180d)?
Shoot it in 60p. Slow motion in sports looks great.
Check this basketball I recently shot at 60p. It looks pretty good in slow motion.

Patssle, when you shot that did you shoot in "60p over 60" mode, then conform footage, or 30pn @ 60fps? The faster stuff - is that what normal "60p over 60" mode looks like, or is it 30pn @ 60fps @ 200%?
I've created four replicated SD DVDs for a college sports recruiting DVD.
We always shoot 720/24pNative. I have a scene settings that is 24pN over 60 for slow motion.
We have created several HD DVDs that look, and recently did a test encode for blu ray authoring.
It also looked good. Client loves it.
Going to SD DVD in DVDSP is a breeze.

I shot 60p over 60 I believe and interpreted the footage at 24p to slow it down. The faster stuff was 60p played at 60p then sped up if needed.
It's a good approach but it takes up a lot of p2 card space.

1.) If I shoot 720p60p with a 350d shutter, will it essentially look just like 720p30p? And if so, does that mean then when played back in slow-motion, all motion/movement would have much more motion blur?
2.) Does 720p60p @ 180d shutter (1/120) create the same kind of motion crispness as 720p30p with a 90d shutter (1/120)? Except just add in more frames? What role does adding in more frames play in the image?

What I've done on these very precise issues is to shoot some test footage, and then examine/compare the results.
Sports footage will present different issues.
What have your tests indicated with different settings and the results?

No, nothing at all like 720/30p. It'll still have twice the motion.
Yes.
Each frame will be equally crisp.
It gives you twice as much motion resolution.
Instead of seeing frames like this:
A---C---E
you'll see
A-B-C-D-E

Thanks Barry. All of that makes sense, except one thing.
You mention in the HVX book that you can emulate framerates by making the shutter slower, and then speeding the footage up by 200%. So why is it that 720p60p @ 350d shutter doesn't look like normal 720p30p @ 180d shutter?

Because that segment was referring to using a shutter speed that's longer than the frame duration, which causes the camcorder to go into "frame accumulation" mode (blending the frames together). That doesn't happen in 720/60p @ 1/60th, you'd have to go to 720/60p @ 1/30th to cause that to happen.
