I am just wondering in this today's technology, any digital movie camera works with a rolling shutter like our movie camera.

What I meant is that the digital camera that took frame by frame and later on play the frames in certain speed, e.g 24 fps?

Do you know any?

Yes and no, Wimbert.
MACHINE VISION cameras are designed to have a trigger input that generates ONE frame of digital video and stores it to an external computer. The software of that computer then generates the video file that presents the individual frames in sequence at the required speed.
They are used extensively in Film Transfer by amateurs and professionals using the "frame by frame " method.
See Videofred's results on other Forums.

I'm not aware of any camera that achieves all those functions in the same unit.

Thanks Martin. Indeed, my DSLR camera can take multiple frames in 1 one second. But this feature more to take the best shoot in speedy action. When the camera is set in this feature, after taking one shoot, to process 10 frames camera needs several second to process it. I can imagine that at 24 fps technically will take an enormous speed and complicate machine to process them, and moreover, film camera is continues shooting until trigger is released.

i understand that some software can play multiple slides in single show, at certain speed desired. But I was thinking a camera that can take 24 fps (as continues movement) until trigger is released. But as I said above, it would take an enormous speed processor which I think in today's technology still no-existent.

My DSLR camera is using mechanical shutter which I think will suddenly give up to open and close 24 times in a second (or 1440 times in a minute or 86,400 times in an hour, or... etc)

I am really curious to know if in high-end machine there is already technology that can process 1440 picture frame in a minute (which I believe will be more than 2 mb/frame).

ps: and I believe if this frame by frame camera is widely available, that is the end of celluloid.
