There are a number of different reasons why your footage may have come out low quality, grainy and full of noise. Fortunately, it is really easy to remove noise from your video in Adobe After Effects — all without plugins!
Note: I start the video out by showing how to export the clip from Premiere Pro. That is actually not a good workflow as it compresses the video and loses you quality right off the bat. I totally missed that as I was focused on the work done in AE and not the overall workflow. The primary reason for grainy footage is having too little light available when you shoot your video. There are three fundamental ways in which your camera can compensate for low light:.
You may often find that your camera is already as the largest aperture smallest number and at the slowest shutter speed possible. The only option left for your camera is to increase the ISO value. If your camera is set to automatic mode that is exactly what is going to happen in those situations. While increasing the ISO value will brighten up the image because the sensor becomes more sensitive to light, it also makes the sensor more sensitive to noise and so your footage will end up looking grainy.
It goes without saying that the best way to reduce noise and grain in your footage is to simply film with more light in your scene to begin with. However, that may not always be possible or you received footage from a client that already contains a lot of noise. Fortunately, even if you did end up with grainy footage, you can easily fix that up using Adobe After Effects.
However, you can also remove noise directly in Adobe After Effects using the inbuilt Remove Grain effect. Here is a screenshot of a video with lots of noise due to a high ISO value. Simply apply the effect to the noisy footage you want to fix.
A small rectangle will appear on top of your footage. This rectangle is the preview region, giving you a preview of what your footage will look like with the final effect applied. If you want to see the noise removed from the entire image, you can always switch the Viewing Mode over to Final Output. This however may slow down your computer as the Remove Grain effect is fairly computationally expensive. The Remove Grain does have a lot of settings that you can adjust and it is important to understand how they affect the noise removal process for optimal results.
These allow you to control how aggressively Adobe After Effects will reduce noise in your video. Higher values will remove more noise, but potentially also make your video slightly blurry.
Here is what happens when you increase the Noise Reduction settings too much. Notice how a lot of the detail has been washed out of the image and everything has become pretty blurry. You can adjust the Number of Passes for more thorough processing, but it will also make your computer work harder.
I recommend slowly increasing this value until you no longer see any improvement. Fairly often I leave it on the default of 3. Another important aspect of removing noise from your video is to understand that the noise is usually different within your red, green and blue channel.
If you look closely you can see that the frequency, intensity and patter on the noise is different across the different colour channels of the image. For situations like this, the Remove Grain effect allows you to adjust the Noise Reduction for each channel independently. Once you have tuned your Noise Reduction Settings and play back your video you may notice that while a large amount of noise may already be gone, you may be able to see some flickering in your footage.
This is caused by the fact that the Remove Grain effect works on every frame of your video independently and consecutive frames have different noise patterns, leading to flickering when you play back your final video. Temporal Filtering will take the noise from consecutive frames into account and compensate for that. Enabling this option should take care of most flickering you may see after removing the initial noise.
However, like any other video processing effect, enabling Temporal Filtering can also have how to apply brown eyeshadow for beginners impacts on your video.
For example, you might see strange blocky artefacts on fast moving objects like in the screenshot below. I recommend going to a frame where these artefacts are most obvious and then adjusting the Motion Sensitivity setting and the Amount of the Temporal Filtering slightly. You have to balance the benefits of reducing the flickering with the amount of artefacts you can live with.
I usually find a good balance somewhere in the middle. You can see these sample points if you change your Viewing Mode to Noise Samples. While the automatic noise sample selection usually provides a good starting point and a decent noise reduction effect, you can often get much better results by specifying the sample points yourself. All of how to record using traktor 2 sample points will collapse to the middle of the preview window.
You can now drag them and place them manually in especially noisy parts of your video within the preview window. You can also adjust their number, size and define which frame of your video to sample in the Sampling tab of the Remove Grain effect.
Manually placing and adjusting the noise sampling points usually give the Remove Grain effect a much better understanding of the pattern of noise in your video and help it reduce it more effectively. One of the big issues with removing noise from your video is that you will usually also remove some detail as the automatic process will struggle to tell the difference. If you look at a closeup of my face after I applied the Remove Grain effect and pushed up the noise reduction settings, you can see how blurry all the details have become.
The Remove Grain effect gives you 2 different ways of retaining detail during the noise reduction process:. In the Fine Tuning section of the Remove Grain effect you will find a number of settings that give you more detailed control over how noise is removed and how small details are treated. The most important one is the Texture setting.
How long can i eat after wisdom tooth extraction this value will retain texture detail within your video. However, if you increase this value too much you may cancel out the noise reduction effect altogether so you have to find a good middle ground.
Another useful option is the Clean Solid Areas setting. Increasing this value will smooth out even areas within your video. Again, it is a matter of tuning in on just the right setting to avoid accidentally blurring away the edges of your image.
If you push the Clean Solid Areas setting up too much, you may see the edges of your objects in the image bleed like the red mobile phone in this screen shot. Finally, another way to retain detail in your video when removing noise is to use the Unsharp Mask. The unsharp mask is a sharpening effect. The name simply derives from the fact that a blurred out, inverted image is used for the sharpening process.
As with all other settings, I like to increase the amount slowly to get optimal results without pushing it too far. If you sharpen your image too much, you may get all your detail back, but you will also be left with a rather harsh looking video. If all of that seems too complicated for you and you want something you can simply slap on and be done, you may want to check out paid 3rd party plugins such as Red Giant Denoiser or ABSoft Neat Video. One thing, when I went for manual sampling, the frame number changed.

How Do I Remove Noise From My Video?

This is the third article about the new release of Premiere Pro and After Effects for video editors. We have already covered:. Creative Cloud 's release of Premiere Pro introduces an update to its sound editing capabilities with a Reduce Reverb slider and an updated Reduce Noise algorithm.
In the video below, I will be taking a closer look at how these two work in a real-world application. The upgrade adds new intelligent algorithms for reducing noise and reducing reverb. These are extremely easy to use because you control them as sliders. The question is whether they can do a decent job. I just want to stress one thing: I'm not a sound guy so please forgive me if you know more about this stuff.
I'm a video editor and whenever I have the opportunity, I would hand over the sound repairing to someone else. I'm testing it from the perspective of someone who has only a basic knowledge about sound.
Keep that in mind. I also think that these are designed with such a user in mind. It's obvious that the two sliders are not the best solutions on the market for noise and reverb reduction. The task that they have in the editing workflow is to do a decent job in a short amount of time.
For me, that's perfect. It will make my life easier. It's time to talk about how the sliders work in action. I tested them on footage of the first video I recorded in my office when it was all empty on the other side of the camera and a reverb here was huge.
The process of working with them looks like this:. This is the way to go about these new features of the Essential Sound panel. I've found that while they do a decent job, the result needs to be normalized again. They drop the gain and that can be a bit frustrating. Overall, taking simplicity into account, I think this is good add on to the existing audio tools in Essential Sound Panel in Premiere Pro.
If we edit the effects in the Effects Control panel, we really have much more possibilities and control over the results. Will you use them in your projects? Let us know in the comment section below.
