Multi GPU not Finalizing Completed Video

Multi GPU setting doesn’t finalize video, freezes at final 30 seconds or less of encoding, however new output video itself seems complete and looks very good. I just have to manually close it out the task as it doesn’t automatically finalize. Having 2 GPU’s saves 50% of the encoding time, so having this work would be great for batch encoding.

I have 2 NVidia Encoders:
Nvidia RTX 4090 Laptop GPU & a RTX 4090 EGPU connected by thunderbolt.
Both are recognized by Topaz & my computer.

To summarize, the UI freezes and when you force quit, the file is exported as expected? Stragely, none of the logs you shared show any command being run at all.

Problem SOLVED. :smiling_face_with_three_hearts:My NVidia RTX4090 eGPU recommends & installs the NVidia desktop version driver by default. My Laptop uses NVidia RTX4090 laptop version driver. I installed the laptop version driver in my eGPU instead of the recommended desktop version. It WORKS Perfectly!!!
