  • Hey all, just changed over the backend after 15 years I figured time to give it a bit of an update, its probably gonna be a bit weird for most of you and i am sure there is a few bugs to work out but it should kinda work the same as before... hopefully :)

Build 15 sneak peak...

How much more light does the RED one need for 120fps? Is there some type of chart that laysout frame rate and increased light needed?
Click to expand...
Every time the frame rate doubles, the amount of light needed doubles. So 48fps needs 2x as much light as 24fps. 96fps = 2x more than 48fps. 120fps = 5x as much light (2.5 more f-stops) than 24fps.

So basically, you would want to use 16mm lenses at 2K to avoid a crop factor, right?

16mm lenses can only cover the 2K frame, they can't be used for 3K or 4K. That doesn't mean you HAVE to use 16mm lenses; of course you could use 35mm lenses too, as the all cover the full 2K frame. But if you want to use inexpensive 16mm lenses, the only format option you have available to you is 2K.

(from 24 to 120 ) isn't the difference 2 stops and some change ?

Another 2k lens option on RED:

B4 HD 2/3" lenses, when used with the RED B4 adaptor, also cover 2k. The B4 adaptor spreads the 2/3" lens coverage the necessary 6% to cover 2k. Higher end HD EFP/ENG zooms have excellent glass. I also have full zoom capablity and start/stop capability on RED ONE using RED's 12v/RS232 bus, via the RED cable to the zoom lens hirose connector. I've been beta testing those cables for RED. With the Fujinon 22x7.3 and Fujinon 13x4.5 lenses I have, in tandem with the RED B4 adaptor, my action subjects footage in 75fps has been excellent. Now to try 120 fps...

I've shot high motion subjects in 2k/75fps with the following lenses: RED 300, Optimo 24-290, Canon FD 150-600, Fujinon 22x7.3, and Fujinon 13x4.5. Footage from the RED 300, Optimo 12x, and Canon 150-600 was crisper in 2k than that from the B4 lenses, as you'd expect because of the extra glass involved in the adaptor to spread the image, but the difference was surprisingly slim and the good B4 lenses did very well in comparison - and the operational utility of servo motors and start/stop on the lenses was a welcome feature.
 
Oh hell yes.

I'm currently in Afghanistan (2nd deployment here), our RED #97x is shipping out here later this week.

It will be the realization of a dream: to take modern archival quality motion footage of our service members. 120fps will be icing on the cake.

Thanks guys.

Great photos,

look forward to see what you capture on RED.

Good luck and please do keep safe.

Ciao

I like the stills Mr Glory...nice work...

Have fun with the RED!

I'd like to see 4K 2.39:1 @ 40fps, and 720P @ 300fps.

1K... not sure what "1k" would be, 1024 x 576? Why stop there? Let's go for widescreen NTSC, 864x480 @ 700fps...

(and then, if and when Red fulfills the original goal of 4K @ 60fps, all these frame rates should double!)

All this should be possible, right? Seriously, it would be very cool if we could dial in custom frame sizes. Might be a hassle to implement through on-camera menus, I can see there being GUI issues, but what about through loadable scene files? Someone could work up a scene file editor program, you type in your desired frame rate and fps, the computer program verifies that it's a valid combination, and then saves it to the SD or CF card. On the Red we already have the ability to load in a "look" from disc...

Barry,

the math behind CMOS sensor is not always that simple. The design approach taken on the RED ONE seems to work on full lines only, so I assume that 2048 lines (4K) will run @ 60Hz, half the amount of lines = 1024 (2K) runs apparently definetly @ 120 Hz. So we can assume something in the near PAL or NTSC region of 512 lines will allow technically 240 Hz.

So the line speed of the sensor seems to be ~1,228,800 lines/second. Divide that by the amount of lines you aim to have:

PAL 1,228,800/576 = ~213 Hz
NTSC 1,228,800/486 = ~252 Hz

Its a bit unfortunate that the region of interest seems not to be possible for parts of lines as well, because then we would have seen drastically higher frame rates. But thats a design issue.

We've been using quite some high speed cameras over here, for years, and there are a few sensors out there that allow pixel bandwidth based regions of interest, which yield some higher rates.

But as we are on it:

When do we finally see PAL and NTSC output frequencies, so we can re-implement wireless transmission for the video village (preferred way on steady-cam use). Its simply a bit uncomfortable use converters on the camera while having handheld mode etc.

Cheers,
Axel
 
The link appears to be dead. . .

I only get high bit characters. No video.

120fps only 2:1?

120fps only 2:1?

Jarred - you haven't responded to my question about 120 fps - is it only 2k 2:1?
The problem with that format is that 99% of projects will have to ditch the sides - doing a "fit to Height" in Redcine.
You have something SUB-HD 1080P.
Almost every project most people shoot finishes in 4:3 or 16:9.
The image ends up cropped to 1,777x 1000 for 16:9 in Redcine.

2000x 1000 = 2,000
1920x 1080 = 2,073

Is there any reason you can't deliver 1920x 1080 at 120fps. Obviously that will be shooting/processing about the same number of pixels in camera, but with a higher-res file in the real world for everything except a cinemascope presentation. ???????????????
 
2.66k

2.66k

Similarly, 3k 2:1 is better than a kick in the teeth, but I might as well be shooting 2.66k - that's where it ends up soon enough in Redcine - and I could have a few more fps, if that is possible.

In other words, for any given project, there's no point in changing the aspect ratio - if vertical resolution for a shot is reduced, why not reduce horizontal resolution as well, AND GET MORE FPS FOR THE SAME FINAL PRODUCT?

Am I missing something here?
 
LOL............... some of these posts just crack me up. Complaining about more features! ====== > wannable :clown2: attitude
