Hey Everyone,

 

In recent beta builds (14.3.0 and newer) we've added support for Apple's Afterburner accelerator card which is an optional component available for 2019 Mac Pro systems. Currently we support decode acceleration of ProRes 4444 and 422 codecs using the Afterburner card. Please note: ProRes RAW acceleration via the Afterburner card is not currently supported - although CPU decompression is available for ProRes RAW. 

The Metal renderer must be selected for use in the applications (this is already the default setting):
  • After Effects (Beta): File > Project Settings... > Video Rendering and Effects > select "Mercury GPU Acceleration (Metal)"
  • Media Encoder (Beta): Preferences > General > Video Rendering > select Renderer: "Mercury Playback Engine GPU Acceleration (Metal) - Recommended"
  • Premiere Pro (Beta): File < Project Settings > General > select Renderer: "Mercury Playback Engine GPU Acceleration (Metal) - Recommended"

 

Unfortunately there is currently no way to identify utilization of the Afterburner card - but if you have a 2019 Mac Pro with an Afterburner card installed, and your workflow contains ProRes 422 or 4444 content,  please share your experience with us in this thread.

 

We look forward to your feedback.
 
Thank you,
Kyle Plumadore

Premiere Pro doesn't seem to be utilizing the Afterburner card much if at all while working with ProRes files attached as proxies to MXF online footage.

 

Media Encoder, on the other, somehow appears to be using the Afterburner quite heavily when encoding to ProRes, which is a bit confounding to me.

 

MenuBar Stats 3 is the software I'm using to measure memory and processor use on the Afterburner card separate from the AMD Radeon Pro Vega II Duo.

Hi RayWood,

 

The last we checked MenuBar Stats 3 did not show Afterburner usage. Can you share a screenshot of where it shows Afterburner usage? Also, Afterburner does not support encoding - only decoding - so it is a bit odd that it would show any usage during encoding to ProRes unless of course your transcode source is ProRes.

 

Thanks,

Kyle

I'm starting to wonder if MenuBar Stats 3 is pulling info from the Vega II Duo and mistaking it for the Afterburner. That would explain why I'm getting these odd readings (it showed usage even when not playing back the ProRes proxies):

Also, here are screenshots of my Media Encoder showing usage as well when encoding MXF to ProRes. This is another reason I think the software is giving me incorrect readings:
