...on my main Intel i9-14900K system. The specs are: Intel i9-14900K 64 GB DDR5-6400 RAM GeForce RTX 4070 Ti 1 TB Samsung 980 PRO SSD (C: drive) 2 TB Samsung 980 PRO (D: drive) Windows 11 Pro 24H2 Premiere Pro 25.1 The integrated Intel UHD Graphics 770 is enabled on this system. I turned on and off hardware decoding and hardware encoding, and I also set the hardware decoder to Intel (Quick Sync) only or Nvidia (NVDEC) only. The hardware encoding is locked to Nvidia (NVENC) only or software only (Intel Quick Sync hardware encoding is not possible with a discrete non-Intel GPU installed). The overall results, in order from slowest to fastest (based on my PugetBench for Premiere Pro scores using the Standard preset): Nvidia hardware decoding enabled, hardware encoding disabled Nvidia hardware decoding enabled, hardware encoding enabled Both hardware decoding and hardware encoding disabled Intel hardware decoding enabled, hardware encoding disabled Hardware decoding disabled, hardware encoding enabled Intel hardware decoding enabled, hardware encoding enabled The result with Premiere Pro set to the default decoder and encoder settings was equal to that achieved with the Nvidia decoder enabled and hardware encoding enabled due to the default decoder setting, which was supposed to utilize both the Intel and Nvidia decoders, was broken in Premiere Pro 25.1. Please note that my findings are for my particular system only. If your system has a weaker CPU, then the hardware decoding performance will always beat software-only decoding. It just so happens that my i9-14900K is more than powerful enough to handle software decoding. If you have the chance to play around with the decoding and encoding settings, please share your findings in this discussion. Randall
