Premiere Pro v25.1+ Cannot Use GPU Hardware Decoding for HEVC 10bit 4:2:0/4:2:2 Files on Network Dri
To the Adobe Team,
Hello,
I would like to report a regression issue encountered in Adobe Premiere Pro since version v25.1, which affects GPU hardware decoding of HEVC video files stored on network drives (NAS).
System Information
-
CPU: Intel Ultra 9 285K
-
GPU: NVIDIA RTX 5090
-
Operating System: Windows 11 (Version 24H2)
-
Storage: NAS connected via 10GbE network, mounted as a network drive (e.g., Z:)
Issue Description
Starting from Premiere Pro v25.1, when video files encoded in HEVC 10-bit 4:2:0 or 4:2:2 are stored on a network drive, the software fails to utilize GPU hardware decoding, instead falling back to CPU decoding. This results in high CPU usage and degraded playback performance.
When the same HEVC files are placed on a local disk, GPU decoding works as expected.
Most importantly, in Premiere Pro v25.0 and earlier, GPU decoding functioned normally even when HEVC files were stored on network drives, which strongly suggests a regression introduced in v25.1.
I also tested with H.264-encoded files and found that GPU hardware decoding works correctly from both local and network paths, regardless of version. The issue appears to affect only HEVC 10-bit 4:2:0 and 4:2:2 formats in newer versions.
Possible Cause
Based on the observed behavior, I suspect that Adobe may have made changes to the HEVC decoding module in v25.1 that introduced one or more of the following:
-
Stricter path validation or access control;
-
Incorrectly classifying network paths as unsupported or insecure for hardware acceleration;
-
A bug that disables GPU decoding for HEVC formats when files are not located on a local disk.
Request and Background
As a professional video production studio, we rely on a centralized NAS storage system for high-speed collaboration and asset management. Our network runs on 10GbE connections, so throughput is not a limiting factor.
We kindly ask the Adobe development team to:
-
Investigate and fix this regression in HEVC GPU decoding behavior;
-
Restore GPU hardware decoding support for HEVC 10bit 4:2:0 and 4:2:2 files on network drives as in earlier versions;
-
Or provide technical clarification and any potential workarounds.
Thank you for your attention and continued improvements to Premiere Pro.
Best regards,
