    It's possible to encode with 10 Bits, what extra command i should add on parameters?

    I found the code by myself online, just add in parameters: -pix_fmt yuv420p10le

    Yes, HEVC NVENC 10-bit encoding is supported — but it depends on your NVIDIA GPU generation.

    Here’s a quick breakdown:
    GPU Architecture HEVC 10-bit NVENC Support
    Maxwell (1st gen) ❌ No
    Maxwell (2nd gen – GTX 950/960) ✅ Limited support
    Pascal (GTX 10xx) ✅ Yes
    Turing (RTX 20xx, GTX 16xx) ✅ Yes + better quality
    Ampere (RTX 30xx) ✅ Yes + improved encoder
    Ada (RTX 40xx) ✅ Yes + AV1 support also

    • So if you're using a GTX 1060, RTX 2060, 3060, etc., you should be able to encode HEVC (H.265) at 10-bit using NVENC.

    If you're using FFmpeg, the command might look like:

    ffmpeg -i input.mp4 -c:v hevc_nvenc -profile:v main10 -b:v 5M output.mp4
