Where is hevc_nvenc (Nvidia NVENC HEVC)?

1. offizieller Beitrag

    I just bought the 2026 version of Voukoder. It works well with my Intel 14900K integrated graphics and the LIBX265 encoder; however, I have a Nvidia RTX 4000 Blackwell card so I of course want to use that. The internet (and AI) say look for "hevc_nvenc" or something similar but I can 't find it anywhere. The Voudoker forum makes reference to hevc_nvenc so I assume it's real? When I open the Voukoder Pro Designer and select the video encoder node I scroll down and down to finally get to "Nvidia (GPU)" with subheadings for AV1, H264, and HEVC. I select the latter but under Format there is no yuv422 10 bit option. Where is the hevc_nvenc encoder, and more specifically, how can I get my gpu to render HEVC 10 bit 422 color? Any guidance is appreciated.

    The hevc_nvenc encoder is exactly the NVIDIA (GPU) HEVC encoder.

    But my info reports that yuv422 10 bit got introduced with the rtx 50 series, not with the rtx 40 series.

    Zitat

    Prior to this architecture, NVIDIA GPUs strictly did not support YUV 4:2:2 in hardware:

    • RTX 40 Series (Ada Lovelace) and older: The hardware blocks were physically restricted to 4:2:0 and 4:4:4 chroma subsampling.
    • The Issue: If you imported 10-bit 4:2:2 footage (a standard format for cameras like the Sony α7 IV, Canon R5, or Panasonic GH6) on an older RTX card, your system had to hand the workload entirely over to the CPU for software decoding and encoding. This frequently resulted in laggy editing timelines and slow export times.

    By adding native 4:2:2 pipelines directly into the silicon of the RTX 50 series, NVIDIA finally closed a long-standing gap that had previously given Intel's Quick Sync and Apple's Silicon Media Engines a distinct advantage for video editors.
