Shutter angle equivalency

I apologize for bringing this up again, but I just wanted to make sure I understand correctly...

-The best shutter angle to shoot at for each frame rate is 180 degree shutter?

-180 degree is always equal to 1/__th of a second. The ___ is 2x the number of the frame rate? 24fps = 1/48th, 30fps = 1/60th?

Now if that is correct, then the best shutter angle to shoot at with 60fps would also be 180 degree, which is equal to 1/120th? Or am I completely mixed up?
 
You are largely correct, with the only exception being the insistence on "best" because, frankly, there is no such thing as an overall "best" for every scenario, there is only such a thing as "best" for a particular scenario.

For general use, yes 180 degrees is a safe way to go. In general, your statements are all correct. I'm just pointing out that several people prefer the look of 200 degrees, which gives about 10% more blur and 10% more exposure. In low light circumstances you may find that you prefer the look of a 220 degree shutter. In high speed action sequences you may prefer the look of a 90 degree, or even a 45 degree shutter. The additional choices are there for a reason.

But unless you're going for a specific special circumstance look, then yes the general idea is that 180 degrees makes for a good default speed.
 
Thanks Barry, I've got one more question. Before getting my HVX, I filmed a lot of skateboarding on a vx1000 at 60i, mostly at a fast shutterspeed like 1/500th or 1/1000th. I never noticed any strobe because it was 60i, but I really likes the way it looked. When I start shooting skateboarding again, I think I'm gonna shoot at 60p, for conversion later to both regular and slow motion 30p. What shutter angle would you reccomend I shoot at to best replicate the old 60i, 1,500th look without looking too stroby?
 
Here is a cool little math equation.

fpsx360=x

x/shutter angle = shutter speed

or x/shutter speed = shutter angle


example:

24x360=8640

8640/180= 48

or 8640/48=180
 
When I use to shoot skiing footage back in the 80's I use to set the hand crank Bolex to 45degree's.. I mainly shot at 60+ frames per sec and the images would be lovely and crisp...

I've never dabbled with video and shutter angles... as the images are recorded rather than reproduced... does a smaller shutter on the HVX increase sharpness or should I say increase the clarity at higher speeds (ie less motion bluer)..???

Cheers
 
Thanks Barry...Excellent... will give it a go next time I'm shooting sports...

Anybody shooting snowboarding or skiing should give it a go... especially when it's a really bright sunny day... the footage will look much better than at 180degrees....

Cheers
