How will undercrank/overcrank work?

[jamesratnarajah]

Hi Guys,

I am a newbie here and so my question may sound very primitive and simple but just thought I would ask. How will the overcrank and undercrank method work? On the HVX200 you set your recording timebase (25p for example) then you set your frame rate (50fps for example) the result is overcranked footage. Will it be a similar process for the Red One?

If this is the case will there be standard timbases 'set in' to choose from i.e. 25p, 30p, 24p then you choose your subsequent frame rate?

Again sorry if this is an excruciatingly simple question :)

I'm probably talking out of my a$$ here, and hopefully someone will correct me if I'm wrong, but I always thought it would record a series of frames similar to a film camera. In other words, capable of being played back at any speed you select.

So then setting the timebase is something you would do in Redcine or your NLE, right? :unsure:

Yes that's exactly how it works. The Project Frame Rate sets the playback speed and timecode count. When in variable speed capture, the camera just stamps each new frame with the next available timecode. On playback everything falls into place as a proper 23.98p, 24p, 25p etc video clip with correct timecode and built in slow motion or speed up motion characteristics.

Hi Stuart

How to you manually control the over/under cracking on the camera.
How user friendly is it?

[Brook Willard]

You have to press a button and then rotate the camera around the lens axis an exact number of times in 4 seconds in a movement akin to a "barrel roll". Want 25FPS? Turn it 25 times. It seems irritating at first, but once you get good at flipping the camera into the air and doing it, it becomes pretty second-nature. The hardest one is 23.976 - that took me a few tries.

[As of NAB, accessing frame rate in the menu system was fast and easy, requiring only a few clicks of the thumb wheel on the back. I have no idea how much it's changed since then. The little thumb wheel joystick will make accessing menus quite simple, particularly to those used to messing with HVX-esque menus. I found the prototype menu system to be easier to use and more logical than Arri's D-20 menu, as an example.]

Again, this is 4-5 month old experience. Who knows how it's changed in the mean time.

stuart, are you speaking specifically of the post production phase (redcode raw in fcp for example) or playback in camera too? can we playback the slow motion shot we just did in camera (redcode or rgb) to verify it's speed/quality before we move on?

i did a search but terms like "playback" pull up just about every single thread.

[Nathan Buxton]

what about ramping? can that be done in-camera? or would we (you) just do it in post?

I'm working on converting a paint can shaker that you just program to do these manouvers as a preset. Think I can bring it in under 10k.

Well that seems like a perfectly fine UI and very similar to some of the gymnastics that other camera's put the operator through. Now, just one question comes to mind. Using this interface, how does one set an interval recording period? Fractional barrel rolls?

Yes, playback in camera too Wigby...

[Craig Schober]

excellent. thanks for the response.

[tj williams]

can I do manual or auto speed ramping?

[Stuart English]

What would you like to be able to do?

[jamesratnarajah]

Hi Stuart,

Thanks for that info, that's made it a whole lot clearer!

[Nathan Buxton]

In terms of ramping, what i would like to see (although i will only be a limited user if a user at all) would be a knob that can pop in and out (like the knobs on the xl-1 that push-click in and out) and enables you to ramp from two defined frame rates. so say set the base frame rate to 24, and the max to 120. you could slowly (or fastly) ramp the speed up to 120fps...

you could, then, for example, shoot a long scene and without cutting ramp to slowmo for an unexpected event. it would be nice.

Who knows what magic the software wizards can come up with as far as a user interface, but I believe the camera body mechanicals were fixed some time ago. I think there are some assignable buttons, but I'm not sure that they're exactly what you mention, and it's a bit late to be adding dedicated knobs to the main body now. This does not rule out an external or third-party controller (connecting via USB? )

There is a separate controller called a "Red Supergrip" which is an external device with some buttons and a joystick, it might have software-selectable controls. Relatively little detailed info has been released about it.

(Note- I'm not associated with Red, this is just FYI as a summary of what I've read here before.)

[Nathan Buxton]

ah yes an external control would be even better. The interface isn't important to me (the pros can figure that out). I would just hope we have the ability to do that somehow.

[Jeremy Hughes]

What would you like to be able to do?

The option of either.

And speaking of speed ramping, will it automatically change the exposure?

[tj williams]

HI Stuart
If you have captured 90FPS in 2K on a 24FPS project then can you build smooth ramps between the nominal speed and the slo mo speed in any length in Red Cine?

[Michael Morlan]

What would you like to be able to do?

Stuart, I would like to be able to setup multiple speed ramps with;

o destination frame rate
o ramp duration
o ramp curve (linear, ease-in, ease-out, ease-in/out)

I would assign the ramp to a button and the operator/a.c. (if not me) would execute each in sequence with subsequent taps of the button.

The way I picture it working, is identical to a follow focus, but obviously with frame-rate being adjusted not focus. Automagic features are nice (set it and forget it) but simplicity is sometimes the key.

SMart ass :)

For those curious, here's how it worked at NAB:

Press a button on the back to pull up the menu. The menu existed on the bottom of the screen and was generally made up of 5 options.

Select an option I can't remeber to get into speed/format info. Click over to frame rate with the joystick and turn the joystick knob to adjust to the desired setting. We're talking 10 seconds.

Thus is a very foggy old memory of a very early prototype. It'd be safer to call it a guess of the functionality instead of a description. Don't hold me to it if I'm wrong.

[Nathan Buxton]

can the knob be used to adjust the framerate while recording?

[jaadgy akanni]

Ok, I'm here trying to figure out why I'm denied the privilege to post new threads, but here's my perhaps stupid question(and suggestion too):
On my akai MPC4000 sampler I have ability to take an audio sample and resample it from 16 bit to 24 bit if I wish, so I was thinking if it would be possible with a digital image to take, let's say a 100fps piece of footage and "resample" it to 120fps(260fps,300fps, etc.) via software, since the camera itself can't do it. Would it be possible to come up with a way in which the software could reprocess footage at a more frames per second for even better overcranking? Doe anyone see where I'm going with this? I'd appreciate someone knowledgeable would answer and enlighten me.
