May I see the rest of the DEBUG logs ZIP file please? It’s important to see the MDE and decisions which preceded the transcode. ---

Download the logs from Plex 1. Recreate the problem 2. Wait about a minute 3. Settings - Server - Troubleshooting - Download Logs 4. Take the ZIP file it gives you 5. Drag it into the Reply window here 6. Let it upload (will convert to a URL when done) 7. Hit REPLY again to finish ---

Yes. 1. You don’t have a QSV (vaapi capable) CPU . That Xeon doesn’t have QSV 2.

yes, QSV is enabled. By default, Plex will pick the first transcoding hardware it finds . How is the machine configured? QSV CPU + GPU ? ---
