Topaz Photo Ai: Denoise and enhance VHS with Nyx

Topaz Photo AiTry it →Watch full video →Topaz Labs ·

Demo summary

The demonstrator applies the Nyx model to denoise and sharpen non-interlaced VHS footage, showing both auto and manual parameter adjustments for grain and noise reduction.

Step-by-step

  1. Select the Nyx model in the enhancement settings
  2. Set Recover Detail to zero to ensure the filter works at 100% without reintroducing original artifacts
  3. Run an initial pass using Auto mode to establish a baseline
  4. Enable manual parameters and click Estimate to let the application analyze surrounding frames
  5. Adjust the Reduce Noise and Compression sliders
  6. Set the Reduce Grain slider to a position slightly behind the noise and compression levels
  7. Increase the Sharpen and Dehalo sliders to refine edges
  8. Lower the Deblur and Anti-aliasing settings if the image appears too soft

Options

  • Toggle between Auto and Manual parameter modes
  • Use the Estimate function to automatically suggest manual slider positions

Watch out for

  • Never set the Reduce Grain slider ahead of the Reduce Noise or Compression sliders, as it becomes too aggressive and pulls details from surrounding pixels

Tips

  • Keep the Reduce Grain, Reduce Noise, and Compression sliders in a 'triangle' formation with grain at the lowest value
  • If dark edges or halos reappear after sharpening, increase the Dehalo setting and slightly decrease Sharpen to find the sweet spot
  • Use Nyx specifically for low lighting, VHS, and VHSC tapes

Highlights

“that's looking pretty darn good so compared to the original this is already enhanced quite a bit”
