If your video is grainy, you will want to try these noise reduction methods to make it less noticeable. When filming, the best thing you can do to combat video noise is to add more light to your shot.Īnd remember, its easier to grade your footage to be darker than to edit out any noise from your footage.

Since the sensor is recording light levels, the darker areas of your shot are the most affected. How you set up your camera will dictate how the sensor measures the information. The electronic sensor creates the noise in the camera (CCD) and measures the light for each pixel in your image. Summary Part 1: What is Noise Reduction Part 2: Steps to Reduce Noise in Adobe Premiere Pro Part 3: Use Dynamic Linking to Reduce Noise in After Effects Part 1: What is Noise Reduction Noise reduction is the process of fixing the grainy areas of the shot. If you do end up needing to fix some noise, here are a couple of simple methods you can try in Premiere Pro CC and After Effects CC, without using plugins. Objects don’t move randomly over time, but noise does.It can spoil an otherwise excellent film Theres no better fix for noisy video footage than taking the time to shoot it right. Video is a changing image, it moves over time. The answer lies on the very nature of video. How can we know that bright spot on the beach is caused by a sand grain or a noisy pixel? What’s different between a video of a sand beach and pure noise? They both have small detail, the pattern is random in most cases and it affects all of the channels. Our goal is to find a criteria which helps us to separate the damage pixels.

A median filter is more subtle, but it will only work when the noise is very visible and very small. A blur filter will remove all the noise, but it will also destroy the rest of the image. You could try to look for small pixels which differ from the surrounding patterns, you could try to smooth the hole images keeping the borders intact, you could apply complex statistical models which decide if a pixel is susceptible to be noisy, etc.īut we do not want to affect the detail and textures of the image. There are many ways to decide how much noise a pixel has.
