workflow terms definition in RED language

[Alexander Alexandrov]

English is not my native language and I get a bit confused with definitions from time to time. Looking at things from a process point of view 1st, rather than the terms they are associated with.

can someone briefly explain the process meaning as it applies to "RED workflow" of the following:

- decode
- transcode
- debayer

what are they? downconversions? downloading? color correcting? i'm probably doing most of the steps in my "new to red" learning process, but simple, down to earth explanation would be a great help

thank u

The R3D is a compressed file, and must be decoded to be viewed. Transcoding is taking an image stored in one codec and converting it to another codec or format. "I transcoded the R3D to Apple ProRes" for instance.
Debayer or Demosaic refers to the process of converting a Bayer pattern color filter array image from a single sensor to a full RGB image. Because the R3D codec stores the compressed RAW sensor data in it's native Bayer pattern form, this is a process that must be done to see a full resolution full color image.

thank u, Graeme!

and where is Debayer step usually done, what apps do it?
(i havent faced a need for pro deliveries yet). but i'm coming from a clipfinder->fcp->color workflow steps.

If you do 2k via half-standard, no debayer takes place. Half high does a special 4k to 2k debayer / downsample. If you go for full 4k, then a debayer must take place. In a 2k Color workflow (4k data seen as 2k) the half-high debayer is used for rendering. A full debayer is used for 2k captured R3Ds.

thank u. and now with the color supporting 4k, it will be full.

Thanks for explaination. They should include this information in the pdf.

and another one: "conform" - is it the process of swapping the transcoded (for example ProresSQ) files with the original ones?

Thanks Graeme for making some things clear for all of us
