Fix export issues in Premiere Pro

If the issue persists, follow these steps:

1. Try exporting your project to a different file format

•  Exporting to H.264 or HEVC? Go to Preferences > Media and deselect Enable hardware accelerated decoding (requires restart).
• If you are not exporting to H.264, or if the issue persists:
  • Choose File > Project Settings > General. The Project Settings window opens. 
  • In the Video Rendering and Playback section, choose Mercury Playback Engine Software Only.

• If you’re using a custom export preset, change to a built-in preset.

• Select Queue to open Media Encoder to export your project using Adobe Media Encoder. An added advantage to using Media Encoder is that you can work on other projects in Premiere Pro.
• If you’re using a third-party transition or plugin, remove that temporarily from the project and export again.
