After Effects

Among the many features offered by After Effects, it is the Remove Grain that actually does the job to remove noise from video footages. However, by smoothing out the video footages to smooth out those noise artifacts, the program is also blurring everything a tiny bit. The downside of this is that some details and sharpness can be removed from the image at the same time. So, it’s a little bit techy to make the balance.

See the steps below how to remove noise from video with After Effects:

Step 1 — After loading the video footages that you want to remove noise from, locate the Remove Grain feature from the Effects & Presets panel and then apply the effect. A small rectangle will appear on top of your noisy footages. This rectangle is the preview region, giving you a preview of what your footages will look like with the final effect applied.

Step 2 — To see the noise removed from your entire video footages, just switch the Viewing Mode to Final Output.

Be aware that doing this may slow down your computer as the Remove Grain effect is a computation intensive process.

Step 3 — Apply some relevant settings to optimize your final video footages. The primary settings for the Remove Grain effect are the Noise Reduction Settings that you can try out to control how aggressively you want After Effects to reduce noise from video footages. Higher values will remove more noise, but potentially also make your video slightly blurry.
