P: Premiere Pro Freeze During Export Using Hardware Encoding (NVIDIA RTX 5070)
Hi Adobe Community,
I'm experiencing consistent freezes when exporting projects using CUDA acceleration with my new NVIDIA GeForce RTX 5070. This occurs in both Adobe Premiere Pro and Media Encoder.
Bug Report Details:
-
Product(s) Affected:
-
Adobe Premiere Pro (25.2)
-
-
Operating System: Windows 11 Pro
-
GPU: ASUS Prime GeForce RTX™ 5070 OC Edition 12GB GDDR7
-
GPU Driver: NVIDIA Studio Driver (Latest version available at the time of this report)
Issue Description:
Since upgrading to the ASUS RTX 5070, Adobe Premiere Pro freeze during export when CUDA acceleration is enabled. The application becomes completely unresponsive at a random percentage of export progress. No error message is displayed, and no crash logs seem to be generated. The application process cannot be terminated via Task Manager, forcing a full PC restart.
Project & Export Settings (Typical Scenario):
-
Source Footage: H.265
-
Sequence Resolution: 1080p
-
Sequence Duration: Approximately 40 minutes
-
Effects Used: Minimal (no heavy effects or LUTs)
-
Preview Rendering: Not used
-
Export Format: H.264
-
Renderer: Mercury Playback Engine GPU Acceleration (CUDA)
-
Encoding: Hardware Encoding
Steps to Reproduce:
- Open a project in Premiere Pro (e.g., a 40-minute timeline with H.265 footage, simple edits, no heavy effects).
- Go to File > Export > Media.
- Set Export Format to H.264.
- Ensure "Performance" is set to "Hardware Encoding."
- Under Video > Encoding Settings (or similar, depending on version), ensure the Renderer is set to "Mercury Playback Engine GPU Acceleration (CUDA)."
- Start the export (either directly from Premiere Pro or by queuing to Media Encoder).
Expected Result:
The export completes successfully（New RTX 5000 series now support 4:2:2 10bit H.265 natively）
Actual Result:
The application (Premiere Pro) freezes at a random point during the export. It becomes unresponsive, and the system requires a hard restart as the application cannot be closed via Task Manager.
Additional Notes:
-
The problem is reproducible in both Premiere Pro direct export and Adobe Media Encoder.
-
Switching to "Software Eng" rendering allows exports to complete, but this is not ideal.
I would appreciate any insights, troubleshooting steps, or guidance on whether this is a known compatibility issue. Please let me know if further information is required.
Thank you!
