Overcranking HMC150?

Hello everyone,

Ok so I read in some threads here about overcranking with clips from the HMC150 and cinematools from FCP. I am a noob to this as the only way I know how to overcrank was in camera with the HVX200. Can someone fill me in on how its done on cinema tools? What settings should the HMC be set to? 720/60p? Thanks
 
Yes it should be 720/60p......

And while we are on the subject can someone explain to me how to properly pull this off with premiere? and also would it effect the process if I am using the panasonic transcoder and work on a DVC Pro file?
 
Shoot in 720p60, and use Log and Transfer to bring the clips into Final Cut (or whatever your preferred way to import). Then just open the imported ProRes file in Cinema Tools and choose "Conform" from the "Clip" menu. Choose 23.98 fps and voila... when you go to FCP, the clip will now be a native 24p file, and will be playing @ 40% speed.
 
I think the ideal shutter speed is 1/120. That way when you slow down, it should feel like 24p @ a 1/48 shutter.

I think its just how you want it to look.

The skate clip that I uploaded yesterday in the "latest project" thread was shot with 1/2000th shutter. The higher the shutter the less blur there will be. So if you want a little more natural blurriness to the slow motion the bring the shutter down. Available light will also dictate how your shutter will be set.

True. As long as your shutter speed is 1/60 or greater, you will be fine.
 
btw. why do people call this overcranked? I mean it's just conforming a 60fps clip to be played at 24fps causing a natural slowdown. The term "overcranking" kinda makes me think that there is heavy tweaking/hacking of camera settings going on.

It's actually faux overcranking. It just appears as if the footage is overcranked.

So instead of the camera doing it, we're doing it in post.
 
I was shooting over the weekend and left the settings at 720/60p.
How can I make 60p clips play smoothly in real time on a 30p time line?
I am noticing some ghosting on the exported real time clips, the slo mo stuff looks crisp
 
From a technical standpoint it's pretty straightforward - just drop every other frame. Your NLE might be trying to over-complicate things, which are you using? If it's Premiere, look to disable "frame blending" I believe it's called (right-click clips in the timeline)

On film cameras, you would crank faster, making more frames come in on the tape in the same available space, being perceived when viewed as slowmotion.

Imagine: you have 15 frames, and have to fit into 10 frame space.
Thats the same idea as having 60 fps, and putting into a 30fps timeline.

Yes, I am using premiere...I will try the disabling "frame blending" and let you know how it goes.

The footage that comes out of this camera makes me feel like I know what I'm doing. I'll post some unedited and edited clips as soon as I get a chance
 
After disabling frame blending on a clip that I want to play in real time is there an additional step I need to perform to get real time speed from a 60p clip in a 30p timeline?

Just disabling the option seems way too easy. i tried it and the files look great but I just want to make sure I don't miss anything.

Thanks

I believe the default is 1/100 and then goes up from there. I tend to use the fastest shutter I can and get a decent exposure. Most of the stuff that I shoot is /500 or higher... It really tends to pop it out and eliminates a lot of the motion blur.

The other nice thing with this cam over the HVX is that the gain is so much better and really usable even at plus 12. The gain on the HVX was absolutely terrible and produced such ghastly footage.
