Redcode for Dragon

[Christoffer Glans]

Depends on the shoot and images. I usually shoot at 5:1, but if I need to push that capacity of the card I go up to 8:1 (in situations without offloading on set like a remote exterior without power).

But I usually think like this
Greenscreen, high details (like heavy foliage), VFX critical images = 3:1 or 4:1
Regular with reframing, normal details, longer depth of focus = 5:1
Regular, normal to low details, no VFX, shorter depth of focus = 8:1
Interview, concert (lock off just shooting the whole thing), some documentary material = 10:1

I also use less compression the lower in resolution I get. 4K or 3K at 4:1.

On weekends I've been shooting various tests and personal creative stuff, and have really grown to like the max compression.

When resolution doesn't matter, and I'm only looking for color and tonality in the larger 6k frame size to be downsampled to 1080p, 22:1 has worked great.

If you are shooting for web, consider a higher compression ration. If you are cropping in, you will need to drop down accordingly. 2k needs at least 8:1 to look good.

Probably an unpopular opinion around here, but it really opens up the camera to be used on more carefree projects without having to maintain a server farm of drives.

It's tough to say, as a hard and fast statement, that any compression ratio is optimal. As Gavin Greenwalt pointed out in his fantastic compression thread, red code quality is hugely reliant on the amount of small detail in the scene. The more detail the camera needs to resolve, the lower the compression ratio needs to be. Furthermore, a higher compression ratio also aggressively attacks chroma rather than luminance, which means that if you are just interested in color, RedCode still matters.

P.s. This is all if you want the best possible image out of your dragon. However, if saving costs on drive space is more important than IQ then I say go for it.

22:1 looks good? that sounds like abit to much to me but ive never tried it

A lot of compression artifacts disappear when you down-convert from 6K (3144p) to 2K (1080p). What DRAGON 6K does give you, that DRAGON 2K does not, is the ability to use one's conventional (S35+) lens arsenal as they were designed to be used. Thus, a 24 T2 lens gives you a slightly wide field of view and a slightly shallow depth of field, instead of giving you the equivalent FOV of a 70mm lens behaving as if shot at T6.

Just don't look at the 1:1 pixels of the original image and nobody gets hurt ;-)

so on minimags 2:1 is possible @ 6K full frame ?

thanks
