Higher framerates and 'scope shooting...

[Dominic Jones]

Hi all,

The issue of reducing the recorded image (and therefore the amount of data it is necessary to process) in order to facilitate 4K RedCode RAW framerates higher than the current 30/60 limit when shooting for a 2:35.1 ratio has already been mentioned in a couple of threads.

Obviously if for some reason this is not possible, then this idea won't be of much use, but if it is it would be great if the camera could reduce the extra vertical framing by only as much as is necessary for a given framerate (i.e. you lose 10% of the frame for 36fps @ 4K, as opposed to the full 25% or so for 48fps, say) - that way you'd still get some re-framing area up to all but the highest possible speeds.

Just a thought...

EDIT: Obviously I mean 2.35:1, not 2:35.1!!! Doh!

More Fps @ 4k Plz.

To the best of my understanding, it is a combination of frame rate & frame size that limits what is doable onboard. My best guess - they need some time to make sure the presently proposed 4K workflow, and then the HD res RGB workflow gets settled first, and ROCK solid, and THEN they can start worrying about these kinds of mods.

They know it is desirable, just give'em time to get it all worked out. Make it work first, then tweak from there...

I agree with MikeCurtis that there are a lot of things on our wish list that are mostly software issues that will be addressed quickly once the main work is done and they start delivering cameras. But it is interesting to speculate and think about what we would like and what is possible. So with that in mind:

What pixel res would we shoot for 2.35 aspect?

Given that the sony 4k projector does 4096x2160 would we want to shoot or end up with 4096 x 1743 or thereabouts.

Is the windowing and/or downsampling heavily in hardware or is it likely that RED can do additional window sizes or downsample sizes through firmware updates?

It seems to me that a lot of us would be willing to sacrifice some vertical resolution to be able to shoot really wide screen material without the headaches of anamorphic.

I come more from the video side of the world, is the 4096x2160 an industry standard or proposed standard for digital cinema?

Absolutely Mike, that's my understanding as well - I merely thought it would be best to put all of the ideas on the plate as early as possible, in case something that was seen as a good idea needs a change that *does* have to be done before the hardware's locked down (and I realise it may be too late for that as well, but there haven't been any posts from the Red team saying "Don't give us any more ideas for now!", so I'm proceeding as if this is not the case).

Certainly wasn't my intention to put any pressure on the Red development team, just give them the best heads-up time I could, for their sake...

Although if they can get it done by camera #1083, that'd be great! :biggrin:

This has been discussed here and on DVXUser -- the idea of shooting 2.35 and using the saved pixels for increased FPS -- but as far as I know, no official word has ever come down.
