New in AME Beta: Native Audio Rendering and Audio Plug-In Manager

Previously, Premiere Pro sequences with third-party audio effects would default to DynamicLink rendering via Premiere Pro, even when the Import sequences natively was enabled. Media Encoder now supports native audio rendering for the audio effects (VST3 and VST plug-ins on both platforms and Audio Units plug-ins on macOS).

Users can control which third-party audio plugins will be loaded for Import sequences natively mode to selectively enable or disable the plug-ins. The effects will be applied in Premiere Pro projects and sent to Media Encoder. To access third-party effects, the plug-ins must be scanned.
