Reducing video quality with GPU

[roseshayan]

Hello!
When I want to reduce the quality of a video, all the pressure is on the CPU and 100% of the CPU power is used. What should I do to reduce this pressure on the GPU? My graphics card is GTX 1660.

From the current compressO source, there is no in-app switch that will move video encoding to the GTX 1660.

The video codec list exposes software codecs only: libx264, libx265, libvpx-vp9, libaom-av1, and mpeg4. The Tauri side passes the selected value directly to FFmpeg as -c:v:0 <codec>, and the default MP4 path is libx264. I also found GPU detection code, but not a call path that selects an FFmpeg hardware encoder such as h264_nvenc or hevc_nvenc.

So with the current app UI, the practical options are to reduce CPU pressure by using faster or lower-cost settings, lowering resolution/FPS, or running smaller batches. Using the NVIDIA encoder would require compressO to expose and pass an NVENC codec to FFmpeg, and the bundled FFmpeg binary would need to include NVENC support.
