Exposures longer than frame rate

[David Goldberg]

With Red is it possible to have an exposure that is longer than the frame rate, for example, shooting 60 fps with a 1/48 sec exposure? In essence, creating a virtual 450 degree shutter angle.

Yes but you need to install a flux capacitor.

Yes but you need to install a flux capacitor.

Hahahahahahahaha.

Yes, breaking the laws of the time/space continium with a camera setting would be impressive.

If that were possible you'd have the shutter covering about 1/3 of your frame. Not a good look at all...

I've wondered if this were possible before, kind of like so you could have a continuous timelapse. I think it's more something you would have to do in post. Set a 360 degree shutter and then do some kind of additive time echo thing. It would take forever to render but would look really cool.

There was quite an interesting discussion about this a while ago, sadly I cannot find it again with all the thread-numbering-mumble-jumbo-thingy.

I think all you'd have to is shoot at 48fps w/ a 360 degree shutter and then speed up the footage in post to 60fps, assuming you don't want the frames to pollute each other.

The HVX allows for some advanced time/space bending. You can shoot 30fps with a 1/15th shutter.

I think there is a very good and very old thread on DVXuser explaining what the camera actually did.

 

[Peter Moretti]

Roberto, I could see this being possible if the shutter was multiple of the frame rate, e.g. 30fps and 1/15th. But I think combining 60fps and 1/48th would be impossilbe for any current camera to do.

Shoot at half or a quarter or less, than your desired frame rate and slow it down in post. Kind of how we used to do it on film with step printing.

 

[Cail Young]

With frame accumulation it's possible but you need enough memory to hold several frame's worth of pixels - quite an issue at 4K@24-30fps.

In short, not happening on the RED ONE. Epic, who knows?

I used to have a Sony camcorder which could do this. Or to be strictly accurate, because it was PAL, it shot at 50 fps interlaced, with exposures of up to 0.5 seconds.

I used this feature for some interesting motion trail effects.

And it didn't have a flux capacitor AFAIK

However, I have not tried this with my Red yet, so no idea if it can do it.
