Any advice for shooting at 100 fps.

Hi everyone,

This is our first time using the RED One camera and we need to shoot a 20 sec Tv comercial, wich consist of a time freeze scene with no motion blurs when the camera is traveling using a Dolly Sprinter.
We are looking for a good configuration (ASA 320 or 800, 2k-3k or 4k ,FPS 100 or 120) that will give us a neat look that will avoid motion blurs and any noise from a wrong exposure. This could be an example of what we are trying to achieve, off course on way lower budget (http://www.ikea.com/ms/en_US/rooms_ideas/ckl/default.html).
Here is a short list of what we had in mind:
*Shooting at 100 fps
*Capture resolution 3k
*35mm Prime lense
*A set of Kino flo 4 bank and a 4000 HMI.


Thanks in advance.

Hi,
You would have to shoot 2K for 100fps. The max fps is 60 at 3K 2:1 resolution.

To avoid motion blur, always shoot at or faster than 180 degree shutter; 1/200 at 100fps. You will need more light due to the faster shutter speed.

Are you sure they shot slo-mo for the Ikea commercial? The Heroes stuff used a totally different technique, I think.

Hi David,

Thank you for your answer and tips, I am going to put more detail in the ligthing so it could be enough for the exposure time. As far as I know they used the MILO with motion control, they actually did several passes back and foward with a high rate of frames / sec. Here is a link with a very good article about it: http://mrmoco.com/Newsletter/news071205.htm

Thanks

You'll need a LOT of light to shoot at 100fps with no motion blur!

Remember that your shutter moves in relation to your frame rate so to do 100fps in a 25fs timeline your shutter will be 4x faster.

1/50 becomes 1/200.

As Michael said, you need A LOT of light.

I did a 120fps shoot the other day at midday on a very sunny day and barely had enough!

Thanks everybody for the insights.

I heard that pulling up ASA to 800 will give me noise on my shots, is there any truth about this? or should I stick with a lower one?

I am planning on bringing as much as possible light to my indoor scene, so I can avoid poor exposure when shooting at 100fps.

Yes I would leave the ASA at 320 and expose for that to get the cleanest image. Think of ASA as gain on a camcorder.
