    Slow-Motion Effect

    Hey guys.  I have a video shoot tomorrow and we be filming an airbag deploying.  Cool huh?  I know! I will be using a Panasonic HPX170 P2 camera.  I was thinking of shooting this air bag deploy at 720/60p.

    Two questions:

    1) What camera setting should I use for this to capture the airbag properly?  The airbag will be deploying extremely fast so I want to capture the motion as best as we can.  I know the camera has overcranking capabilites but not sure if I should change my current camera settings.

    2) I did slow down a test file of 720/60p and slowed it down using the timewrap effect within Avid.  It looked good but when slowing it down to play back at 15%, it was a little choppy.  I also tried using the FluidMotion option.  It smoothed the clip but introduced some weird image artifacts around my talent.

    Just curious what you would do.

    Re: Slow-Motion Effect

    I don't want to give you any bad advice re: camera settings, so I won't.

    My go to slo mo effect in Avid is to use the timewarp, set to blended VTR or blended interpolated (test to decide which), then set my input to Film with 2:3 pulldown, detecting the pulldown rate, and set my output to Film with 2:3 pulldown as well.

    Hope this helps!

    Zac,

    Why should I choose blended VTR or blended interpolated?  Is their a reason to choose one over the other?  I see there are lots of choices in that drop-down.  The help file doesn't explain it in layman terms nor does it tell you to choose one over the other if your source footage is progressive.

    Re: Slow-Motion Effect

    The reason to go with one of those two is just personal experience. I find those two give me the most consistent smooth image quality, without artifacting, which is why I stay away from Fluid for the most part.

    I've never heard a layman version of the differences between each, my preferences come mostly from testing and seeing how they look.

    For footage that is already progressive, I've had the same results with the aforementioned settings.

    The deployment of the airbag is so extremely fast that I believe you will need a high speed camera (at least 300 fps) to capture anything that won't look like a blur. It's alot like trying to film the impact of a bullet on a target. Any chance you can rent one?

    Re: Slow-Motion Effect

    If you can I suggest getting either a Phantom camera and operator, which will shoot 720P at 2000fps, or 1080 at 1000fps TOTALLY smooth, no effects requires, or a Weisscam, virtually the same performance, but you could operate it yourself with a touch of training. Using the Avid to get you slow motion is a bandaid for what you are apparently trying to do. With Avid and the Pany, you still only get 60 fps, and just basically multiply frames you already have to make it APPEAR slow. With the other cameras you actually DO have the frames you need to make it slow and all the detail you could ever want.

    Re: Slow-Motion Effect

    Ok yeah that makes sense.  I have heard of the Phantom camera shooting at 2000 FPS.  I will just film it at 60 FPS and slow it down in Avid.  I will post my findings.  Thanks!

    Re: Slow-Motion Effect

    Only other thing you can try (other than getting a true fast over-crank camera) is set the shutter speed as high as possible on the pany (or if you're in "film camera" operation set the shutter angle as low as it goes)

    good luck

    Re: Slow-Motion Effect

    Hey guys.  Sorry it has taken me so long to respond back with my findings.  I just ended up shooting the airbag at 720/60p.  I will slow it down within Avid.  The first airbag we were far away and the second one, we got closer.

    I agree in that if we wanted a high-rez slo-mo we would have to rent a different camera.  Thanks!

    If you got MC5 open the file from a bin on a lower framerate project as 24.

    This will give you a better start.
