  • 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 :)

Low res modes on Scarlet = FPS + focal length boost?

Is it reasonable to assume that Scarlet will be able to shoot at higher FPS when shooting at 2k or lower? Same for 2.35:1. I believe this is the case with Epic right?

Also, a 2k mode would crop into the sensor slightly giving the fixed lens a boost in focal length (or equivalent focal length if you get me). Has red commented on this anywhere? Personally I would love to be able to shoot at 200fps or higher if I dropped the resolution to 2k.

Thoughts?
 
Beyond cropping to 16:9, 2:1 or 2.4:1 it doesn't seem likely that Scarlet will have smaller crop options. Will there be a 2k crop mode? Not much reason for it on Scarlet except to get higher frame rates.

Yeah people really seems to like the ability to shoot slo-mo... I mean, 2/3rds of all the Epic footage we've seen so far has been 2K 300 fps footage.

As explained to me in another thread, it's especially good for sports. Snow Skiing, surfing, football, drag racing, etc., can all benefit from slo mo footage to examine the action.

So if you shoot sports, this is probably high on your list of features to have.
 
Of course, you'd be cropping the already small sensor to tiny proportions so your DOF and lens characteristics would change dramatically.
 
120 fps at 3k seems perfect to me. If magic bullet like can handle this, why do you want to shoot more fps on 2k. It's like a nonsense to me. At 300 or 500 fps, it begins that nothing happens during 10 seconds.
For example I movix company makes some of the slowest cams in the world (2500fps). These images are wonderful but you gotta wait 3 minutes before something happens on the screen ! See what I mean ? ;)
 
Bayer filter

Bayer filter

I think with the introduction of 4K Bayer sensors with RED ONE, the world of digital cinematography has evolved past SD/HD past.

Scarlet shoots 2880x1620 like Alexa for good reasons, it gives you a 1.5x oversample for the de-Bayer to null some of the de-Bayer artfacts and to reduce the excess blur from the OLPF filter.

By the time Scarlet gets into its final sales, Bayer cameras will only 1920x1080 pixel sensors will be past their prime.

The future of Digital Cinema Cameras is to have sensors at least 2880x1620 and in a few more years at least 3840x2160.

Although you can get an image with small sub-samples of a Bayer sensor, you cannot fully avoid Bayer artifacts when the images are enlarged, so shooting even 1280x720 and enlarging it to 1920x1080 is something you would want to avoid for HD use.

For transfer to 35mm movie film you want a Bayer sensor that is 2560x1440 to give you 1280x720 RGB resolution on the film.

I was at a XD digital theatre yesterday, and the digital resolution is more than typical 35mm film 4th generation print projection, so there is a new standard of image quality needed for future use of footage shot today. If people get real 4K TV sets in the next 20 years, hopefully there will be a standard of quality for what gets shown on it, and Super16 resolution is not enough.

If you sub-sample at 640x360 you can get higher fps (if the REDCODE compressor can keep up) but the red/blue resolution at that is only about 180 video lines per image height, or like the slow speed on VHS, so blowing that up to 4K is going to show artifacts.
 
Sensor cropping doesn't seem like a big deal. Unlike DSLRs, you aren't cropping to lots of photosites you skipped over. You may as well just crop in post with Scarlet footage.

But as far as FPS goes, I would welcome options all the way down to 720p. You could probably get a decent image and if it is 300fps, those are the kinds of speeds where you see hummingbirds and insect wings in a whole new light. You make tradeoffs, but its worth having the option.
 
+1 for more FPS :thumbup1:

I was thinking about this too. And it would be a cool feature. That seems to be the most delivered format for me most of the time.

Who wouldn't want such a feature, if it doesn't add to the cost?

I'm sure 720p bayer from Scarlet would be at least the same quality as the 720/60p of any DSLR out there.

It would be great for me. I shoot skiing and surfing mostly. I usually still deliver my media at 720p and it would be insane to capture a 300fps shot around that range. Lets hope thats a hidden secret in the camera they're not talking about. Can we shoot them a message or propose that somewhere?
 
I don't think they need a feature-request from us. ;) They'll push Scarlet to its limits, like they're doing it with R1 and EPIC already. I'm sure about that.
So if its possible to integrate crop-modes with higher framerates then we will see it, maybe later via software-update.

Yeah I figured as much! Goodness I'm getting myself way to excited about this camera
