While CS6 lacks the powerful, one-click denoising of modern software like Neat Video or Premiere Pro CC’s native tools, you can still achieve impressive results. The Median filter is the most effective built-in denoiser in CS6. It works by replacing each pixel with the median value of surrounding pixels, effectively smoothing out grain.

Note: Premiere Pro CS6 is legacy software (released in 2012). It does not have the modern "Reduce Noise" or "VR De-noise" effects found in CC versions. However, you can still reduce noise effectively using built-in tools and a specific workflow. Noise—grainy specks of digital artifacts—is the enemy of clean video footage. Whether you shot in low light, used a high ISO, or are dealing with compression artifacts, Adobe Premiere Pro CS6 offers several methods to clean up your image.
