  • 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 :)

Technology depresses me. I'll just wait and look at the pictures.

5D is 1.2K, Scarlet will be 2.4K, which is double.

I'm not going to bother arguing what resolves what...

But a jump from 1.2K to 2.4K is actually four times the spatial resolution. Remember, video has a height that increases according to width.
 
One thing I don't get is that the 5K Epic resolves to somewhere near 4K (or 4.5K). But it is also refered to as a 13,8 MP camera. How can the picture in videomode not be the acutal 5K size, but when it's only one frame it is?

It is the actual 5k size. All of the pixels are in every frame, motion or still. No pixels are left out.

What we are talking about is the measured visual resolution of a 5k 13.8 MP frame on a test chart. What we actually see in the image, which is not the same as the number of pixels. The visual resolution of the image is affected by the smoothing characteristics of the low pass filter and the quality of the lens as well as the image processing. But every pixel of that 5k frame is in the image. This is true of all fixed pattern digital sensors, not just Bayer sensors. The Panasonic AF-100 for instance produces a 1920x1080p frame, but to prevent aliasing and moire artifacts it is filtered to 800 lines vertical resolution. 3-chip HD cameras are limited by their prism design and filtering. Without the filters, resolution is still limited by aliasing artifacts in the image, so no sensor will visually resolve an image equal to the total pixel count.

Ah okay. Thank you, now I understand.
 
In an ideal world, you probably don't want actual measurable resolution to match the pixel resolution exactly due to aliasing. On the other hand, we don't often shoot 4K line charts in the real world where you'd get into a situation where the lines of the image line-up perfectly with the pixel pattern.

It's a nice looking lizard, but not much to go by really.

Honestly, in terms of the Scarlet, there isn't much to go by right now. I think in total we have a handful of compressed stills, two short compressed videos of about 10 seconds TRT, and the .R3D of Felix.

There isn't a Scarlet sizzle reel or a selection of "demo" videos shot by different DPs from around the world.

...yet. I'm sure when Jim and the RED team decide the time is right, we will know everything we want to and see plenty of footage.

Nice but extremely short. Looking forward to seeing something more substantial.

Maybe something with pretty girls instead of animals?

If you really want to get a better idea of what Scarlet is about, download the chicken .r3d file and the correct redcine-x 356e version for your computer.
Redcine runs out of its own folder after you decompress it.

Decompress the Chicken.r3d in a video directory so you know where it is. In Redcine click the browser tab at the left edge of the screen, find the r3d clip, double click it to load it into the viewer. Then just play with all the image grading controls on the right side. You will learn more about Red and raw digital cinema vs video from this than any compressed web video you will ever see.
