Denoise

FFMPEG Builder: Denoise

Adds a denoise filter to the FFmpeg Builder command to reduce noise and grain in the video file.

Strength​

The strength of the denoising filter to be applied. This controls how aggressively the filter smooths out noise in the video.

  • 0 – No denoise applied. The video remains unchanged.
  • 50 – Medium denoise. Reduces noticeable noise while preserving most detail.
  • 100 – Maximum denoise. Strongly reduces noise, but may also soften fine details in the video.

The actual effect and available options may vary depending on the hardware acceleration being used:

  • NVENC / NVIDIA GPU – Uses nvdenoise, which supports a strength value between 0 and 1.
  • Intel QSV – Uses vpp_qsv=denoise, which supports values from 0–64.
  • VAAPI – Uses denoise_vaapi=default with standard intensity.
  • CPU – Uses hqdn3d for software denoising.

If multiple hardware options are available, the filter automatically selects the fastest supported backend.
