Below are several examples of clips with visible noise of different nature. Generally, noise can be brought in by the video camera sensor and signal amplifier, by electric interference, by compression, etc. Neat Video can significantly improve the quality of such video by reducing the objectionable noise.

This video contains heavy noise produced by the camera working in a high-gain mode. Neat Video reduces this noise, preserves the underlying details and makes the clip usable:

Note: Most video compression methods work better on noise-free video data, so the filtered version of such a clip can be encoded to a significantly smaller file. Therefore, Neat Video helps to clean up the video and at the same time to make the resulting video file smaller.

This clip contains strong visible noise introduced by the air transmission of TV signal and further aggravated by the TV-tuner software's compression. Neat Video reduces the noise and produces a much cleaner video clip.

This clip contains the noise and radio interference from the air transmittion. The interference has a periodic structure (the banding in the original). Neat Video clears these noise elements, preserves and reveals true details and produces a clean video output.

  (Neat Video) "reduced the noise by an incredible amount and made the footage much better", Patrick Lawler
  
  The original 1080p clip contains strong noise produced by the 7D DSLR camera working in high ISO mode and in low light conditions. There are also compression artifacts. Neat Video clears the objectionable noise producing a much cleaner HD clip.
