slowmotion

A 1/250th of a second shutter is pretty fast for any overcrank that the HVX is capable of. Why so fast; what was your reasoning?
 
At 60 fps a 1/250th shutter is equivalent of just under 90 degrees which is a very short shutter period. Even overcranked, something near a 180 degree shutter would be most typical. Certainly a range of shutter angles (periods) is acceptable, but 1/250th is going to be a 2 stop hit in sensitivity.
 
I was shooting fast finger movings.
settings:
-iris open
-shutter 250
-frame rate 50 fps
-rec format 720pn
on the end it was a littlebit blury.
 
What was the distance to the subject (these finger-movings?). If they're very close, then the amount of motion in radial degrees relative to the focal point (I mean it spans a larger portion of the field of view than something farther away) is large and coud look jumpy even at 50 fps.
 
Are you looking to get motion blur free shots? If so, at that distance with a set of fast moving fingers, you may need a really fast shutter and a lot of light.
 
Yes I'm looking to get the clearest picture without any motion blur.Your advice sounds good to me, so I'm going right now to find more light.I will post the results!
Thanks to all:)
 
When you have movement across a wide segment of the image in a short time, it's going to look jumpy no matter what your shutter speed is. Since you're looking for slow-mo anyhow, in addition to adding lots of light, I'd ask the finger-mover to ease off the pace a bit...if it has to be in synch with something (music?) then slow that down too for the recording, proportionally to your degree of overcrank.
