Apple Afterburner Acceleration
Apple Afterburner is an accelerator card for the Mac Pro (2019), created to enhance Apple ProRes and ProRes RAW workflows for film and video professionals. Afterburner accelerates decoding and playback of multiple streams of ProRes and Pro Res RAW video files.
You must call this function to load the ProRes and ProRes RAW decoders so the Afterburner card can accelerate ProRes and ProRes RAW decoding and playback.
If the decoders aren’t loaded, the system performs nonaccelerated software playback and decoding of ProRes and ProRes RAW video files.
