Which converter uses the video card when converting?

Question

Video

Tell me a converter program that can cut, glue videos, but the most important thing is to use the hardware capabilities of the nVidia card when encoding.

Answer 1

To "cut and glue videos", "hardware capabilities of the nVIDIA card" are not needed. All this can be done without recoding.
If you need to transcode: Avidemux .

Answer 2

ffmpeg or gstreamer if you have the right map. You also need to understand that due to the need to drive uncompressed video in the GPU, the performance will not be fantastically high
