Best mode for normal speed and smooth slows?

Hi, I'm still new to this..

Which PH mode will give me the progressive film look, normal speed footage and smooth slow motion when needed? If it's 1080 50i how will it handle being de-interlaced in post? (to give it film look)

And what shutter speed will suit which ever mode best?

I know my question reflects that I want it all, and maybe that's naive..
If not possible, film look and smooth slows are more critical than resolution to me.

I will be editing in fcp 6.0.5
Thanks
 
No mode will give you progressive film look right of of the box. But the progressive modes are probably more suitable for simulating film look than the interlaced ones. Most people think and argue that film look is associated with 24 frames per second because that's what we're used to see when we go to the movies. IMO image and color play a much more important role than number of frames per second. I think you can have a film look style image with let's say 48, 50 or even 60 frames per second even if this is much smoother than what we're used to see when watching films. It really boils down to what you define as "film look".

It's actually difficult to find a mode which helps you to achieve all the things you want. Usually when shooting for slow motion you want to have very slow shutter speeds, because it gives you much clearer still images with less motion blur but when shooting 24 or 25 you want higher shutter speeds because it will result in smoother motion.
 
for slow motion you can shoot in 60p (only available in 720 though). once you have your footage logged and transfered into final cut...find the clip you want in slow motion in the capture scratch folder for your project...right click it and open with Cinema Tools. In the lower right corner of the viewer, conform your footage from 60p to 24p.

Here is some footage I took using that method: http://www.youtube.com/watch?v=5B4wv46hwsI

The last clip in that was actually shot in 24p, and yes most people shoot in 24p when going for a film look. I agree that color and light sensitivity in an image DO play a huge roll in getting it to look more like film, but that is actually achieved by doing some minor balancing and gamma/saturation correction. I hope this helps you some.
 
Like whitecrow said.

720/60p conformed to 24p or 30p for smooth slo-mo but crank the shutter speed up to 1/500 if possible. This will cause less strobing in the image once slowed down.
 
Btw. you can also save a "reference clip" of your 60p/50p material in Quicktime Pro which will only take a few kilobytes and conform that one to 24/25 fps. That way you have two clips at the size of one in two different speeds.

I could not agree more in that it takes more than 24 frames per second to get the film look. Gamma being a big part of the equation however I do think once the lighting and gamma issues have be set to best make video look like film the 24 fps does have a role in furthering that film look moreso than any other current frame rate.
 
Thanks for the input guys.

Lets say that I needed to shoot full res: 1080 50i - would that not give me the same option to create smooth slows via cinema tools? And then apply the progressive look in post, by interpolating / de-interlacing both normal speed and the conformed slows?

This is what I used to do when shooting sd with my dvx100, shoot interlaced and then de-interlace - worked well to get fairly smooth slows and a filmic look.

Thanks again.

I suggest avoiding shooting 1080i. It's an ancient relict and it will die sooner or later. If you need high frame rates then go with 720p. It will be less troublesome and progressive images are the strength of the HMC.
 
To pailes, now what do you mean by that - you still need a 1080 resolution to fill out a HD screen right?

Has anyone tried shooting 1080 50/60i and then de-interlaced in post?
It would seem to me that you could get the most out of you're footage if you have time to do it this way..

Thanks
 
With the 150 you can shoot 1080p or 1080i so I would not shoot 1080i and then de-interlace it.

If your output is going to be progressive then shoot in 1080 PH mode.
Then you'll get the most this camera has to offer.
 
In my opinion 720p material will look better than 1080i material that has been deinterlaced.

To Xsjado:
720p is another HD resolution which is only available in progressive but offers higher frame rates than 1080p currently does. The entire resolution is 1280x720 pixels of purely progressive image. Since you said that slow motion capability is more important to you than resolution you should really go with 720p.

You can watch 720p on every HD TV or HD display. In the worst case you can still upscale 720p to 1080p and it will probably look a bit softer.
 
Alright. To hidef1080, I'm just pointing out that shooting 50i contra shooting 25p in 1080 would give you better slow, even if you de-interlace it? Seeing that the camera can't record 1080 50p.

I will conduct some tests as soon as i get the camera, comparing de-interlaced 1080 50i against 720 50p, both slows and normal speed.

Thanks for the advise though, cheers

Ps. here is some old de-interlaced footage I shot with a dvx100: http://vimeo.com/1330933

There is a very simple reason for this: The current HD standard does not define such a mode. I've read that internally the HMC always captures 1080p with 50/60 fps and then creates 1080i or 720p out of it.
