Video noise can appear in video clips recorded in low-light conditions, or in clips recorded with small image-sensor devices such as smartphones or small portable cameras. Video noise resembles static, or a snow flurry-like random dot pattern superimposed on the video image, similar to the grainy texture visible in low-light or underexposed photographic film.
To reduce video noise in a video clip, add the Noise Reduction effect, then adjust its settings.
Add the Noise Reduction clip effect
You can add the Noise Reduction effect to standard or 360° video clips in your project timeline.
- To open the Effects Browser, choose Window > Show in Workspace > Effects (or press Command–5).
- In the Video category of the Effects browser, click Basics to display effects for standard video clips, or click 360° to display effects for 360° video clips. You can also type in "Noise Reduction" in the search field at the bottom of the Effects browser.
- To preview the Noise Reduction effect on the clip in your timeline, skim the Noise Reduction (or 360° Noise Reduction) effect thumbnail in the Effects browser.
- Drag the effect to the clip in the timeline. The first time you add the effect, Final Cut Pro analyzes the clip for noise. You can see the results in a second or two after Final Cut Pro has completed the analysis."
If you’re adding multiple effects to a clip, add Noise Reduction as the first effect, so that it appears at the top of the effects list. You can also drag the Noise Reduction effect to the top of the list to rearrange the order of processing. This ensures the best performance and results.
Adjust Noise Reduction clip effect settings
You can adjust the Noise Reduction effect after you add it to a clip in the timeline.
- Select the clip in the timeline with the effect.
- Choose Window > Show in Workspace > Inspector (or press Command–4), then click to show the Video inspector.
- Select the Noise Reduction effect in the inspector, then adjust its settings:
- To choose the amount of noise reduction to apply, click the Amount pop-up menu and choose the amount.
- To choose the amount of sharpness to apply, click the Sharpness pop-up menu and choose the amount.
- To examine the effect closely, set the Zoom pop-up menu in the upper-right corner of the viewer to 100%. When you’re finished, choose Fit from the same menu (or press Shift-Z).
