Please Improve Metal Support in macOS
Metal support in Premiere Pro 2020 is currently very bad. On a Radeon VII under macOS Catalina, I'm seeing encode times from a ProRes 4444 timeline to ProRes HQ output taking 45-50 minutes for a 4-minute piece. That same piece encoded in under 10-minutes using OpenCL. Additionally, native Adobe plugins that work fine in OpenCL give a red banner CPU warning under Metal. There is no RED SDK support either. Clearly Metal render support needs work, especially if OpenCL is being deprecated. Please improve Metal support under macOS in Premiere Pro and across all professional media creation applications. Thanks.

Metal performance is MUCH WORSE in Pr 15 than in Pr 14.

Though I don't doubt this is a problem and there is much room for improvement in the way Premiere Pro talks to external graphics cards, I have had mixed results. When I have my wx9100 externally connected to my laptop, I am able to select OpenCL. It does not show up as deprecated. If I select Metal, hardware encoding is not enabled for export. It might depend on the capacities of your graphics card. Also, there are main known problems in Catalina with Premiere Pro. I'm running Mojave still. I saw an article on Creative Cow where a guy bought one of the new Mac Pros and had to return it because the graphics cards did not play well with Premiere Pro under Catalina. Apple and Adobe really need to talk about this and get the problem solved. It is in the interest of both, as well as of those who rely on them.
