GPU RAW Media Decoding

Flame Premium and Lustre support GPU RAW Media Decoding for the ARRIRAW and RED file formats, providing much faster decoding speeds. GPU RAW Media Decoding is enabled by default, if the following conditions are met:

• GPU RAW Media Decoding requires the NVidia Quadro 6000, Quadro M6000 or Quadro K6000.
• You must update to the latest DKU.
• For ARRIRAW media, Debayering must be set to ADA-SW5. This is the default setting.
  Note: In Lustre, the new ADA 5 SW Sharpening controls are located in Image / Transcode / Format menu. As always, you can copy these settings using the Selector.
• For RED, Colour Science must be set to version 3.x. This is the default setting.

Improved OpenEXR support (import and export):

• Support for version 2.2 of the OpenEXR format.
• Support for new compressions:
  • DWAA: JPEG-like lossy compression format. Compresses 32 scanlines together.
  • DWAB: Same as DWAA, but compresses blocks of 256 scanlines.

  These new compressions have their own export presets.

Improved Canon XF-AVC support (import):

• Support for XF-AVC 12-bit 444 MXF files.

Improved Panasonic VariCam support (import):

• Support for Panasonic Varicam 12-bit 444 MXF media files.

Performance enhancements (import):

• TIFF decoding is now faster, which should noticeably improve TIFF playback performance.

Improved DPX support

• 12-bit packed DPX created by Blackmagic Design Resolve are now correctly read by Flame Premium. In previous versions, red and blue channels were reversed because, while the DPX metadata says the file is RGB-encoded, the file is actually BGR-encoded.

About GPU Decoding and Wiretap Gateway Slaves

With the recent introduction of GPU decoding, the concept of Wiretap Gateway local decoding slaves is being slowly phased out.

The slaves mechanism had a significant impact on performances for R3D CPU Decoding. No slaves will be used by default for R3D decoding when a GPU decoding capable system is detected (Q6000 and above) unless NumLocalSlaves is explicitly set to a non zero value (it is commented out by default). See the comments in the [Slaves] section of the file /usr/discreet/wiretapgateway/cfg/wiretapgateway.cfg.

Keep in mind that, as mentionned in the wiretapgateway.cfg file, R3D files using Color Science 2.x or HDRx cannot be GPU-decoded, in which case you will need to configure NumLocalSlaves.
