How does DeBayering work within a CineForm RAW workflow?

At some point in a workflow that uses Bayer or CFA sensors, the DeBayer operation must be performed. It is up to your knowledge of the post-production tools and their capabilities to determine when to perform the DeBayer operation. 
 
CineForm performs the DeBayer operation in two different ways:  
 
Dynamic DeBayer which allows playback of multiple streams of CineForm RAW files (up to 4K) in real time within a calling application, including within an editing or compositing environment. In this mode the source file remains CineForm RAW, but the CineForm decoder DeBayers the CineForm RAW data in real time and presents it to the calling application as traditional YUV or RGB . This mode defers the need to perform a rendered DeBayer until later in the post workflow. The CineForm decoder performs the dynamic DeBayer operation automatically when decoding CineForm RAW data. 
 
DeBayer during Rendering: At the time a render is performed on a CineForm RAW file, the result is always a traditional RGB (CineForm 444) or YUV (CineForm Intermediate) file based on user choice.  
 
CineForm RAW is based on the same underlying Wavelet algorithm architecture as CineForm Intermediate, and is the name CineForm gives to the compression of raw sensor data. Cineform RAW files (like CineForm Intermediate and CineForm 444) exploit the multi-resolution decoding nature inherent when using Wavelets codecs. The multi-resolution nature of Wavelet codecs assists in the real-time, multi-stream editing workflow provided by CineForm products.  
 
CineForm RAW files can be moved onto the timelines of supported NLEs, compositing and effects apps, and even played within Windows Media Player or QuickTime player. Further, within an NLE or compositing environment, you can inter-mix CineForm RAW, CineForm Intermediate, and CineForm 444 media – even on the same timeline. The CineForm decoder understands the differences in each of the file formats and converts the data (including dynamic DeBayering) to the YUV or RBG format requested by the calling application.
