Workflow:
- open Premiere CC 2019, import media to new project, produce final edit. Working resolution 1920x1080 throughout.
- Export Media, choose Format: Voukoder. Preset: Custom previous settings are remembered and recalled by Premiere.
- Go through Voukoder tabs, first changing audio codec and bit rate, then changing video format to x265.
- Check video codec options and amend (Preset, Tuning, Enable High-Tier, Strategy and CRF).
- Check Filters tab - two properties still present including one to scale output to 960x540; use Remove button to delete them.
- Save Adobe encoder export preset
- Encode the three minute video, which takes almost an hour
- Play back rendered video - it has been cropped to the top-left 960x540 pixels.
