Anybody knows how to convert 1/192 shutter speed to shutter angle here?
If shutter angle was 180deg then the shutter speed should be 1/144
and if shutter angle would be 120deg then shutter speed will be 1/216

so where 1/192 speed is coming from?
 
The camera does not have a mechanical shutter so I assume you can select 1/192 as a shutter speed option regardless of the frame rate selected -- it's not mechanically tied into the frame rate as a spinning shutter is.

I'm sure one could do the math to find out a theoretical shutter angle to get 1/192 at 72 fps.
 
132 degrees?

360/1 = 1/72 = one frame

Shutter Speed divided by framerate == [(1/196)/(1/72)] == 72/196 = 0.367 of each frame's potential exposure time is exposed.

.367 * 360 = 132.2 degrees.

edit: or more simply...

Calculating Shutter Angle Based on Framerate and Shutter Speed said:
Shutter Angle = 360*FPS*Desired Shutter Speed.

132 = 360 * 72 frames per second * 1/196 of a second... I think.

Jim this is great news, I am so ready for RED Day and all the RED glass I can get my hands on! Is there any chance you can get one in Gibby's hands for LART? (Dates are Nov. 17-18th)

I know that you are extremely familar w/ non- hard lined EFP shooting... When you are out shooting (one man/one camera), do you ever feel the need to have a s16 or B4 HD zoom for greater mobility? Do you think you (RED) might add something like this in the future? I just think if you guys made a pl mount EFP style powered zoom lens with the build of...

a canon Canon Super 16 Cine Zoom Lens 10.6 to 180mm

or...

the Canon Super 16 Cine Zoom Lens 6.6 to 66mm you would further RED's cause to be THE singular acquisition tool that supports almost any style of shooting for any type of content. Even just 20% off Canons list price would allow you guys to deeply penetrate the EFP/Docco/HD markets (***Addendum***This of course would be for single sensor or s16 film cameras--not 3ccd cameras-- hence the need for pl not a b4 --sorry if I caused confusion). I know these are very complex lenses, I just think you guys would open yourselves up to much greater markets and quell the REDHEAD/Jackleg Boogey man mentality to the people protecting their own legacy investments. Instead you hit them with something that they can benefit greatly from as well... the walls of dissent will fade through consent. I promise you. :nerd:

Sorry for all the question, just dying to shoot with such nice gear (that I own) :-).

Cheers,

I definately agree with Andrew on this. I was thinking the same thing. I would also take it further and have red design an on lens motor drive similar to what's on a B4 lens. Jim have you thought about this?

Thanks! Guys, so 1/192 is the absolute actual speed regardless of the fps.
I wasn’t sure of that, since such a strange value of 1/192
As long as we have option to enter shutter speed as a fraction of time (above example) or as a shutter angle I will be more then happy.
Someone mentioned that this is the case?
Andrew
