  • 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 :)

Redalert to DPX... Please explain?

10bit DPX is fine. Just don't use linear light with it. Use Redlog or REC709 gamma, or one of the PDLog options.

From a quick read of the first couple of pages from Apples's Color Manual, it looks like it will work with 10bit log DPX files OK as an uncompressed sequence, so I assume you'd have to generate the log DPX files from RC, then load those, rather than trying to import from .R3D through the PDlog curve and clipping data. Haven't really looked into it though.
 
Thanks CWS, the problem is not with the importing of the dpx log files out of Redcine into Color, but that Color seems to assume that any DPX log files it imports are 95-685 range, I can't find where in Color you can change the settings for the log files black and white points and gamma etc the way you can adjust the loglin input settings in Shake for example. Any suggestions appreciated.

Color looks for header settings in imported DPX files, and sets the black, white and gamma accordingly. This from the Color manual:

The Settings 2 Tab
This second tab contains additional settings that let you modify the header data of DPX image files.
- Override Header Settings: Turning this setting on overrides the following settings in the DPX header for the current shot.
- Log: This setting lets you enable or disable the log to linear image conversion that Color automatically performs to 10-bit log DPX and Cineon files.
- Printing Density: This pop-up menu is only selectable when the current project is set to use Cineon or DPX image sequences. It lets you explicitly choose the numeric range of values that are used to process color to ensure compatibility with your post- production pipeline. These options determine what the black and white points are set to in media that’s rendered out of Color. There are three options:
- Film (95 Black – 685 White : Logarithmic)
- Video (65 Black – 940 White : Linear)
- Linear (0 Black – 1023 White)

Which would suggest PDlog685 is the best curve for Color.
 
Sorry but I still don't get this... how would I setup color to ingest REDLog dpx sequences the proper way?
I've being playing with it... and all the detail is there, it just jumps aroung the tone scale like crazy depending on how you set things up...

Could it be done with the settings of the primary in room? With the luma curve? Maybe with a LUT?
