How to Denoise a Video Like a Pro

Ever wondered how to make your videos look more professional by reducing noise? Video noise can make footage grainy and unclear. This guide shows you how to denoise a video and remove video grain to upscale video to 4K quality.

You can easily clean up your videos with video denoiser tools like Adobe Premiere Pro and AnyEnhancer. Learn about different types of video noise and how to fix each one.

These steps will help you enhance your video quality. Follow these tips to make your videos sharp, clear, and professional! But before denoising a video, let’s look at what video noise is.

What is Video Noise?

Video noise, often called grain, makes video footage look unclear. It appears as random specks across the image, especially in dark areas.

Sources of Video Noise:

• Camera Sensor Limitations: Smaller sensors in cameras capture less light. This lack of light causes more noise because the sensor amplifies the signal, including unwanted noise.
• Low-Light Conditions: In poor lighting, cameras struggle to capture clear images. They enhance the signal to get more light. But this also increases noise, making the video look grainy.
• High ISO Settings: The camera becomes more sensitive to light with increased ISO. In contrast, it brightens the image, it also adds noise, reducing detail and making the video look rough.
• Compression Artifacts: Compressing videos to save space can create blocky or blurry spots. These artifacts further degrade the video’s quality.

Now that you know the sources of video noise. Next, let’s look at its types so you can understand better how to denoise a video.

Types of Video Noise:

• Gaussian Noise: This type of noise looks like random speckles across the entire image. This happens because of electronic interference in the camera sensor. It follows a bell-shaped distribution, affecting all pixels to some extent.
• Salt-and-Pepper Noise: This noise appears as random black-and-white dots on the image. Sudden disturbances in the video signal cause it. It can make some parts of the image very bright or very dark.
• Poisson Noise: This type of noise is common in low-light situations. It happens due to the random nature of light hitting the sensor. It makes the image look grainy, especially in dark areas.
• Speckle Noise: This noise is often seen in radar and ultrasound images. It comes from the coherent processing of scattered signals. It looks like a grainy texture overlaying the image, reducing clarity.

By understanding these types of noise, you can better manage and reduce them. This ensures clearer and more appealing video footage.

Denoising Videos using Adobe Premiere Pro [Step-by-Step Guide]

Use the built-in denoising tools to remove video grain with Adobe Premiere Pro. One effective tool is the Median effect. Follow these steps to denoise video in Premiere Pro:

Step 1. Import and Prepare Your Video 

Import your video into Premiere Pro by using “File > Import” or pressing Ctrl + I (Windows) or Cmd + I (MacOS). Create a new sequence by dragging your video to the timeline.

Step 2. Apply the Median Effect 

In the Effects panel, search for “Median” under “Video Effects > Noise & Grain.” Drag the Median effect to your video clip in the timeline.

Step 3. Adjust Median Settings 

In the Effects Control panel, locate the Median effect and expand its settings. Adjust the “Radius” setting from 0. Increase it to reduce noise. But avoid over-blurring the image.

Step 4. Use Masks for Targeted Noise Reduction

If needed, use masks to focus on specific noisy areas. Use the Pen tool to draw masks or choose a pre-defined shape. This way, you can reduce noise without affecting the entire clip.

Adjust the “Feather” setting to blend the mask edges smoothly. Increase the “Radius” to balance noise reduction and detail preservation.

FAQs on Video Denoising

What are common video denoising techniques?

Here are some popular methods for reducing noise in video footage:

1. Median Filtering: Averages the values of nearby pixels to smooth out small specks while preserving edges.
2. Temporal Averaging: Uses data from several frames to reduce noise, working best in scenes without much movement.
3. Gaussian Blur: Softens the entire image to lessen noise but may also obscure fine details.
4. Wavelet Transform: Separates the actual image data from noise for finer control over noise reduction.
5. Non-Local Means (NLM): Compares different parts of the image, averaging similar areas to reduce noise and maintain textures.

How does video denoising differ from image denoising?

Video denoising is different from image denoising mainly because it involves multiple frames. Here are the main differences:

• Temporal Information: Video denoising uses details from adjacent frames to reduce noise, which single images don’t have.
• Movement Consideration: Motion between frames must be considered to avoid visual errors.
• Complexity: Denoising videos is more complicated and requires more computing power because of the motion and amount of data.
• Speed Requirements: Video denoising often needs to happen quickly, even in real-time, unlike image denoising which can be processed more slowly.

These factors make video denoising a more involved process than working with still images.

Where is video denoising used?

Video denoising improves video quality across several fields. It’s used in film and TV to enhance visual clarity. Security teams use it to clear up surveillance footage, which is crucial for identifying important details. In medicine, it helps create clearer diagnostic images. For video calls, it ensure smoother communication. Drone operators also rely on it to sharpen aerial footage. This technique is essential for delivering clearer and more professional results in various applications.

Final Words!

Knowing how to denoise a video can make a big difference. Clearer, sharper videos look more professional and are more enjoyable to watch.

Tools like Adobe Premiere Pro make this process easier. Understanding different types of video noise is also important. These methods help you clean up your footage, improving the overall quality.
