Ideas for Higher Frame Rates on R-1

[Julio Quintana]

Hey guys. I know that Epic is going to solve all these problems, but in the meantime, I was thinking of some ways to get slightly higher frame rates on the RED right now.

My first suggestion is through aspect ratio. Right now the only true 2.35 setting is in 4.5K, which is great, but why can't we get 2.35 in all the resolutions instead of having to crop from 2:1? Would 2k 2.35 be able to go over 120fps? Or 3k 2.35 over 60fps? Even if it's only a slight increase, it's still nice to have the option.

My other suggestion would be a lower RedCode. Jim mentioned that he was impressed with the quality of RC10, so I was wondering if that could be a helpful way to increase framerates. I actually really like 3K overcranked, but if I could shoot 4K 2.35 RedCode10 at 48fps, I would be very happy.

Anyways, I'm sure the brains at RED have already thought of these things, but I figured I would just throw them out there just in case.

Higher end Redcode rates are especially important for high FPS shooting.

Don't quote me on this, but shooting 48fps at 4.5k using Redcode10 would be the equivlent of shooting 24fps at Redcode5. I don't think Red would would be too happy with giving the userbase this option, as there would be a significant (and noticable) reduction in picture quality.

I'm lobbying for lower bitrate REDCODE for 3K for quite some time.

I'm not sure about the new cameras' RGB recording, if it takes less space I'm game, we just need some space saver as well.

Why have less options?

Ah. Good point. But I guess what I mean is, if Redcode 10 looks pretty good at 24fps, then give us Redcode 20 for shooting at 48fps.

Aside from the Redcode option, I don't see any reason why a true 2.35 option isn't available at every resolution since it would save space without affecting quality.

RGB will hardly take less space...

I agree on the 2.35 option, although shooting 2:1 gives you a bit of wiggle room in post with repositioning and resizing with the option of masking to whatever your desired aspect ratio is.

I still think Red would never give the option of shooting less than Redcode28 (especially for higher frame rates) for fear of opening up a can of worms, although it would definitely be nice to be able shoot faster frame rates using the Red One.

 

[Julio Quintana]

I don't really understand the "can of worms" argument. 2K is MUCH lower quality than 4K, but we still have it as an option to allow higher frame rates. I would bet that 4K RC10 cuts better with 4K RC28 than 2K does. I have never seen RC10 so only someone from RED could confirm my guess.

Redcode 10, or even 8, would be a tool for particular situations, just like 2K is right now. As a camera designed for professionals, I think it's smart to give us options and trust that we will use the appropriate settings for the particular job at hand.

I'm on your side Julio, I think it would be a great option. I just think Red have their reasons for limiting the data rates/framerates like they have.

I think it would be very interesting to compare a clip shot at 48fps 2K Redcode36 and a clip shot at 48fps 4K Redcode10 .

Band width is the problem. The max input to the redone redcode chip is 4k x 16/9 x 30fps.
Redcode 10 or redcode 36 only affect to the recording media (output). Not the input bandwith.

I agree with the 2.35 3k and 2k option that Julio suggest. I think it can be a good idea that can be implemented into epic too.


Saludos,

Jose.

Jose, can you or someone at RED elaborate on this a little? What is the "Redcode chip"?

What I want to say with chip is the CPU or processor, or the part of the camera that compress the signal that come from the sensor and go to the hdd or cf. The maximun that this part can process in real time is 4k 16/9 30fps. If you want more fps you must go uncompressed and pay for that.
