Problem
Hardware decoding is disabled by an incompatible driver, forcing software decoding for compressed camera media.
Solution
Root Cause / Diagnostic:
A corrupted or outdated GPU display driver causes the NLE's hardware acceleration subsystem to fail API feature checks (NVDEC/QuickSync/Metal). The application silently falls back to software CPU decoding, causing frame drops and severe playback stutter on HEVC/H.264 clips.
Actionable Fix:
1. Perform a clean installation of the latest GPU Studio Driver (for NVIDIA) or certified enterprise driver, and verify that Hardware Accelerated Decoding is enabled in NLE preferences.
2. Verify that your specific camera media chroma subsampling (e.g., 10-bit 4:2:2 HEVC) is supported by your GPU hardware decoder; if not, configure Intel QuickSync or generate proxies.
3. Monitor GPU Video Decode engine activity in Task Manager or GPU-Z during playback to confirm active hardware offloading.
Pro Tip:
Always install NVIDIA "Studio Drivers" rather than "Game Ready Drivers" on editing workstations; Studio drivers undergo rigorous stability certification with major NLE platforms to ensure flawless hardware decode support.
