Stills resolution of the Scarlet 3K

[Terry VerHaar]

I was led to believe that there was not going to be no cropping. If you choose HD1080 then the full area of the sensor is still utilized.

I was wondering if the sensor is pegged back in it's resolution for video, whereas digital stills go the full hog.

It must be right that the frame size of stills must match the same as video. I guess if you want the 3K Scarlet to create stills greater than 5MP, then it's best to get a professional digital stills camera or go for one of the high-end Scarlet's or Epic's.

The sensor is 3K and that's all there is.

So, what you end up with, in stills or video frames, as has been stated, is around 5 MP or so. Why would that indicate any cropping? I believe that the 1080P output will be the result of an in-camera down-rez, but I could be wrong on that. I don't, however, think it is the result of windowing the sensor.

It's a reasonable assumption that there will always be scaling of the record format to delivery format.

For 1080p or 720p HD video - 16:9 aspect image - you would use 2880 x 1620 RAW pixels.

For 2K movies - in Scope 2.39:1 aspect - you would use 3072 x 1288 RAW pixels.

For 2K movies - in Flat 1.85:1 aspect - you would use 2998 x 1620 RAW pixels.

You can always choose to record the Full Frame resolution of 3072 x 1620 at up to 120 fps and crop down from there - for either video or stills...

Thank you, Stuart!

BTW: each of the following have a native 1.9:1 aspect; so very easy to scale to fit.

4096 x 2160 (DCI 4K container)

5120 x 2700 (EPIC MX sensor)

3072 x 1620 (Scarlet 2/3 sensor)

I wonder if Ted or someone at RED could tell us what the resolution would be for stills on the RED Scarlet 3K and other cameras?

A rough and approximate guide based on the full sensor area and, of course, with the caveat that 'everything is subject to change'.

G Lap - interesting information to see all in one place. One question - why do you indicate the RED 2/3" and S35 sensors (first and third in the list) as "native 16:9" when, in fact, their H x V pixel counts would indicate a different ratio than the 1.78 of of 16:9? Scarlet 2/3" at 3072 x 1620 and S35 at 5120 x 2700 are both a ratio of 1.89, not the same as 16:9. What did I miss?

[G Lap]

You didn't miss anything Terry.....as I said, approximate, rough and ready from a Stills perspective. Feel free to do accurate conversions if you have the time :). I'll amend my table when I can get around to it.

Well looking at those figures the Monstro is definitely worth it's name!

It seems people are confusing themselves by mixing up their numbers. A megapixel is a million pixels. 3072 x 1620 (the resolution of the Scarlet), equals 4.98 megapixels. The RED ONE takes 11.48 megapixel stills and 11.48 megapixel video, as it's sensor is 4520 x 2540.

The highest-end monstro sensor has a resolution of 28000 x 9334, or 261 megapixels.

Tom - I think most people who were coming up with 8 MP on the RED ONE (M sensor) were doing the "back of the envelope" math of 4K x 2K to get the 8 MP. Of course, you are correct about the size of the whole sensor and the resulting picture size. And, of course, the MX sensor is 5120 x 2700 for a whopping 13.8 MP.
