This list delivered us the best beta testers the last time around so I am going to start here and see if there's any interested beta testers for the new upcoming versions of AfterCodecs for Premiere Pro and Adobe Media Encoder.
In a nutshell AfterCodecs allows you to export (up to 8K) directly to ProRes (Mac and Windows), H264, H265 and HAP without needing to go through an intermediate format. The encoding is also faster and more efficient (ie smaller file sizes).
