  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

..is it possible to shoot 24 fps with a 1/8 shutter on the epic?
many thanks?
p.
 
If each frame is 1/24 of a second, then anything slower than 1/24 is physically impossible. Truth is, anything less than 1/48 can start looking very odd for a 24fps segment.
 
You cannot have a longer exposure than the framerate. Kinda wouldn't work as anything but 8fps anyway....

Curios as to what you try to achieve.

What you could do, is shoot 8 fps with a 360 degree (or 1/8) shutter, and triple the frames in post. That would give some of the same effect...
 
People will shoot 1/24 to get an additional stop of light given the right subject but anything slower is not possible.

I wonder, could you set up three cameras and synchonize them to shoot 8fps each but slightly off set so that when you played it back it would in fact be 24fps 1/8 shutter? The blur would overlap but it might have an interesting temporal feel as it would be real time.
 
Looks like about 12fps at 1/12. Then adjust the timebase of your clip to 24fps through a 50% speed reduction. You could play with other frame rates and shutter settings as well but that's my guess.
 
From what the OP said...

I think you just shoot 24FPS at 1/24.... then create 2 more tracks. Offset by one frame, and reduce transparency.

33%/66%/ and 100%....

That would technically be 24FPS, at 1/8 shutter : )

Kind of impossible. But what do you think of my method?
 
The Scott's do this all the time. "Step framing" is one name for it. But as many here have described - shoot at a lower frame rate (with relative exposure so that you get motion blur) then retime to "real time" in your editor of choice. I think James is right - 12fps. I have had good results at 8fps. But haven't done it since the film days. What's old is new again!
 
thanks a lot guys,
this was my guess aswell,
to shoot 12 or 8 frames
and fix it through the
timebase in editing.
will try and post the result
in the near future...
 
Is easy to do in AE, setup a linear project ... then in comp1 drop the footage in 3 times ... making sure the footage is shifted by 1 frame for each time you drop it(also the redlinear is set on that footage). ONLY do a add between the layers (so you do 2 adds). Then drop comp1 into comp2, and do a lin2log in comp2 to output. it needs to be done using the 32 bpc linear and you must do "add"s on the layers. (in the red log workflow discussion i'm perty sure there is something exactly how to do a linear project in AE). Shoot the footage at 24 fps at 360 shutter (i.e. 1/24 +1/24+1/24 = 1/8).
