I've had a thread going over on RedUser here: http://www.reduser.net/forum/showthread.php?72431-Premiere-Media-Encod er-Render-Tests-Matrox-CompressHD-Card-Results
Basically in the source settings for any .r3d file in Premiere, you can choose High, Medium, or Low for debayer. I've run tests using High vs Low, and the encode times are exactly the same. I'm assuming something is wrong?! If you use full vs any partial debayer in RedCineX, the full debayer always takes much longer to complete.
Also, another user posted that he sees no quality difference between selecting High vs Low debayer in Premiere.
Is this feature not working??
As it turns out, the Debayer Detail setting in CS5.5 is a subtle sharpening control which has little/nothing to do with debayer resolution:
The debayer quality is handled automatically.
This doesn't seem to be documented anywhere, just took me a few days to find (and still trying to find just how the automatic control works). Oh well, it's only been four months!
