完成上述设置后，导出的视频测试发现，使用NVIDIA显卡时，硬件加速使用的是CUDA核心，而不是使用显卡自带的硬件编码器（NVIDIA NVENC）。为什么不使用编码性能更高的硬件编码？

As we can't see the rest of the export settings, we can't tell what you're actually doing there. So it's hard to say.

Everyone's mileage always varies ...

In fact, I think most people are confused that NVIDIA video coding acceleration has two different schemes: 1. Use the graphics card CUDA universal core to do coding acceleration; 2. It is encoded by the video hardware coding core that comes with the video card (NVIDIA NVENC). premiere uses cuda security, but obviously the performance is lower than the latter!

After the above Settings, the exported video test found that when using NVIDIA graphics card, the hardware acceleration was using CUDA core, rather than using the hardware encoder (NVIDIA NVENC) that came with the graphics card. Why not use hardware encoding with higher coding performance?
