You might find you can uncheck "Limit luminance" completely and just control the mask with the hue and saturation. Once you have the mask, a quick improvement is to reduce the Saturation slider a lot, and then the Gain slider a bit until the luminance matches. Then click on "Show mask" and tweak the other parameters such as "Smooth" until you get a nice mask. I then dragged the 2 "High" sliders to the far right, to unlimit the maximum luminance and saturation.
There is a long-standing bug whereby the rectangular marquee does not display as you select the area. I much prefer working with it in the Custom mode.įirst pick "Select effect range" and sample a part that includes the most saturated area of pink. U/V controls how much noise is removed from variations in colour.įrequency controls how much noise is removed dependent on the frequency of the data.You can tone down the pinks somewhat with the Color Corrector (Secondary), or even 2 of them in series: By default it is set at 80%, as removing all of the noise from the brightness tends to not look as good. Y controls how much noise is removed from variations in brightness, of the image. These controls allow you to adjust how much of the noise is removed. But as the value is increased, more of the noise might be brought back as well. Keep Edges - This slider sometimes helps to bring more of the edges back. It is easier to edit these slider if viewing the correct frequency: simply change the view to one of the frequencies then change the frequency options level to correspond with the frequency slider. The sliders act like a graph, adjusting one will cause the nearby sliders to also be adjusted.Ĭhannel - These controls allow you to change the noise threshold depending on the YUV channel.įrequency - This allows you to change the noise threshold depending on the frequency of the data. If the problem is in the white areas, adjust the ‘100’ slider. If, for example, not enough noise is being removed from dark areas, just increase the threshold of the ‘0’ slider. The controls under this group help the plugin to identify what is and isn’t noise, by manually adjusting the threshold values.īrightness - The controls under this group, allow you to change the threshold values dependent on the brightness of the image. Updates the threshold values in the ‘Threshold - Brightness’ control group.ĭiscards the original analysis that was performed and re-analyzes with the currently selected analysis area. Used when noise amount varies depending on the brightness. This control allows you to increase the contrast, to help you to see it. Sometimes the changes in frequency are too subtle to see. Level - The frequency level to be viewed.Ĭontrast - Allows you to change the contrast of the displayed frequency. Only visible if the selected View is one of the frequency options. The more frames it uses, the more time it will take to render, but usually with superior results.įrequency V - shows how much the v color changes at the selected frequency level The process can be further improved by increasing the number of frames used during the analysis. This will analyze the difference in the noise levels, between the brightness of the original analysis and the brightness of the new analysis region. Move the control points so that the analysis box is over darker noisy area.Ĭlick the Analyze Brightness button in the Analyze control group. To further refine, change the View setting to Analysis Box. Ideally select a flat region with mid-level brightness.Ĭlick the Analyze button to analyze the selected area. This will provide the effect with input to analyze the video. This box should be positioned over a noisy area of the frame. This can be adjusted using the two control points.
Professional noise reduction is possible with the denoise effect.Īfter the effect is applied to a noisy layer a highlight box will be displayed in the Viewer.
