  • 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 :)

I'm a little confused about how Color works with RED footage.

I can take R3D files directly into Color, but if I use FCP and "native" then "send to Color" I get .mov files that look like wrapped R3D files.

What is the difference between importing R3D files and using send to Color?
Does Color access the full 4K information or does it only use 2K. If it only uses 2K then is this system any better then making DPX files?
 
HI Irri thats my doubt too...
 
with 4k color uses 2k (half debayer to RGB 16bit)
with 3k color uses 1.5k (half debayer to RGB 16bit)
with 2k color uses 2k (full debayer... I think... RGB 16bit)

K resolutions are relative as you have "only" 75% of the K resolution with a RED CMO debayer.

As of today...

As I know...

Thanks Patrick.

So if I am exporting 2K from 4K files I get the same amount of information as if I did the same thing in RedCine? e.g. the 4HD to 1080, 4 photosites per pixel thing?

As I understand it would be near to equal to an :

half debayer high from the 4k r3d downsized to 2k.

With this procedure you don't use the whole resolution (3,2k theorical) of your picture and you loose the oversampling capacity of your 4k picture. I would estimate your 2k resolution to about 1.5k...

... :sick:

If you use 4k in Color, for playback it uses "half standard" and for rendering, set the proxy rez to full and it uses "half high". "Half high" does a combined demosaic and downsample from the 4k to 2k and looks, even though I say it my self, rather nice indeed.

Full 2k to 2k demosaic.

Great. Thanks.

Tried some side by side comparison doing my workflow tests and actually the quality/resolution difference is quite striking to me.
Here you can see a detail from a dpx (3K R3D) rendered out from Color and on the right a detail from a dpx (same 3K R3D) rendered out from Recine:

Lot of details have been lost 'innit?
As i know 2K processing is a Color limit i guess there's nothing we can do about it until Apple does something ... wonder if 4K HD can give better results ?(i'm still on b16)

Also when testing i've seen that if i send to Color a sequence made using proxies ( F, H, M or P ) Color reads anyway from R3D files, as if i had ingested in FCP using "native" instead of using proxies directly, so, what's the point of spending time ingesting files? the only difference i see is are default scaling of shots but it can be fixed in seconds in the geometry room ...

Color is only using 1.5K of resolution for the 3K R3D files.

yes, understood. Just testing what this actually means visually.
I'll try to do the same comparison using 4k files and 4k HD files when i'll have a chance ... liked the girl? :love:

still puzzled by the difference from sending proxies or ingested "native" files to color ...:mellow:
 
Apart from the bug with RED originals longer than 2 GB (which can be fixed with Colorfixer by H. G. Daun), the images from proxies or wrapped native files are exactly the same in Color.

I've tried working by direct dragging in the (H or M) proxy files, but I can't seem to get my FCP sequence setting so that it will play smooth without rendering - can you tell me how you are using these files?
