Video noise is a common issue that can significantly affect the quality of your footage. Whether you're shooting in low light or using high ISO settings, video noise can manifest as graininess, random speckles, or unwanted visual artifacts. The presence of noise can significantly diminish the overall quality of your project, thereby rendering denoising an essential phase in post-production. Adobe Premiere Pro, recognized as one of the most robust video editing software options on the market, provides various methods to efficiently reduce noise in video footage, either through its built-in features or by utilizing plugins. This is a full guide to show you how to denoise video in Premiere.
Table des matières
Video noise refers to random variations of brightness or color information in images, which can create a grainy or speckled appearance. This often occurs when recording in low-light conditions or with cameras set at high ISO levels. Noise can be particularly noticeable in shadows or dark areas of footage, where it appears as graininess or flickering pixels. While some degree of noise is inevitable in certain shooting conditions, reducing it in post-production is essential for creating polished, professional-quality videos.
Premiere Pro offers several tools for reducing video noise. While it doesn't have a dedicated denoising effect, It is still possible to attain remarkable outcomes by utilizing the integrated effects and settings. The Lumetri Color Panel is a versatile tool in Premiere Pro that can help reduce noise while color-grading your footage.
Import your footage
Open Premiere Pro and import your video clip into the timeline that you want to denoise.
Open the Lumetri Color panel
Aller vers Fenêtre > Lumetri Color to open the Lumetri Color panel.
Reduce noise with Color Wheels & Match
In the Lumetri Color panel, go to the Color Wheels & Match section. Adjust the Midtones and Shadows sliders to reduce noise subtly. Increasing the Shadows slightly can help reduce noise in darker areas.
Apply Gaussian Blur
Add a Gaussian Blur effect (Effets > Blur & Sharpen > Gaussian Blur) to your clip. Apply a small amount (e.g., 2-3) to reduce the noise while maintaining detail. Be cautious not to over-blur, as this can lead to a loss of sharpness.
Fine-tune with the Sharpen effect
After blurring, you can add a Aiguiser effect (Effets > Blur & Sharpen > Aiguiser) to regain some of the detail lost. A value between 5 and 10 is typically sufficient.
Make any final adjustments using the Lumetri Color panel, ensuring your footage maintains its visual integrity while minimizing noise.
If you are satisfied with the effect, just export the video with a clear vision.
Personal tip: When using the Lumetri Color panel, always monitor your scopes (Waveform, Vectorscope) to ensure you’re not losing too much detail or altering the color balance excessively. Denoising is often a balance between reducing noise and retaining the natural look of the footage.
While Premiere Pro’s built-in tools can be effective, using a dedicated plugin like Neat Video can significantly enhance your denoising process. Neat Video is a highly regarded denoising plugin known for its advanced noise-reduction capabilities.
Install Neat Video
Start by downloading and installing the Neat Video plugin from its official website. After the installation is complete, you'll find it in the Effects panel within Premiere Pro.
Apply Neat Video to your clip
To use the Neat Video effect, drag it from the Effects panel and drop it onto your video clip in the timeline.
Build a Noise profile
Cliquer sur Open Neat Video in the Effect Controls panel to open the Neat Video interface.
In the Neat Video interface, click Auto Profile to create a noise profile based on your footage. The plugin will analyze the video and identify the noise pattern.
Adjust noise reduction settings
After profiling, you can adjust the noise reduction settings manually. Neat Video allows for precise control over noise reduction, including separate controls for temporal and spatial noise.
Preview and render the video
Preview the effect in the Neat Video window, then click Appliquer to return to Premiere Pro. The plugin will process the footage and apply the noise reduction.
Because Neat Video is a resource-intensive plugin, rendering your footage will take some time. Once the process is complete, you’ll notice a significant reduction in noise without a substantial loss of detail.
Personal tip: Neat Video’s strength lies in its customization options. Experiment with the settings to find the right balance for your footage. Also, consider using the plugin sparingly on clips where noise is most noticeable to save processing time.
If you find Premiere Pro’s denoising process complex or time-consuming, Films Aiseesoft offers a simpler alternative. This user-friendly software is designed for quick and effective video editing and includes a dedicated denoising feature.
Add video file
First, download the free version of Filmai from its official site. After installation, launch the program.
To bring in your video, either click on the Add Video button or simply drag and drop your file into the workspace.
Select Video Upscaler
Filmai offers several enhancement tools, including Video Upscaler and HDR Upscaler. To remove grain from your video, choose the Video Upscaler model and then hit Appliquer.
Denoise and upscale video
Next, you'll enter the enhancement settings screen. Here, select an AI model- either Real World or Anime - and pick your desired upscale resolution, ranging from 1x to 4x. If your goal is to denoise without changing the resolution, choose the 1x option.
Don’t forget to fine-tune the Export settings, such as format and audio preferences. Before finalizing, use the preview function to see how your video will look and make any necessary adjustments.
Export video
When satisfied with the results, click Exporter tout to let Filmai apply the enhancements. Your cleaned-up video will be saved in the format you've selected.
Aiseesoft Filmai is perfect for beginners or those who need a quick solution. The automatic noise reduction works well for most videos, though it may not offer the same level of detail and control as Neat Video or Premiere Pro’s built-in tools.
What is the best video denoiser?
Neat Video is widely regarded as one of the best video denoisers available due to its advanced algorithms and customizable settings.
What is the best Denoise plugin for Premiere Pro?
Again, Neat Video is the go-to plugin for Premiere Pro users seeking top-tier noise reduction.
How to reduce noise without losing sharpness?
The key is to find a balance between noise reduction and detail preservation. Tools like Gaussian Blur with Sharpen in Premiere Pro or fine-tuning settings in Neat Video can help maintain sharpness while reducing noise.
Conclusion
Denoising is an essential part of video post-production, especially when working with footage shot in challenging conditions. Whether you choose to use Adobe Premiere Pro’s built-in tools or a powerful plugin like Neat Video, you can reduce the grain of a video successfully. However, if you want an easier tool, Aiseesoft Filmai is a good option to enhance the quality of your videos and create a polished final production.
