In this tutorial I will show you how to fix a video with amount of noise applying noise reduction.

Let's go to Color section, right click on the first node and add a series node before.

Now we go to the Motion Effects panel:

First thing, Temporal Noise Reduction, select the frames in this case 5.

We change the mode from faster to better.

In motion range section, it depends of your camera movement, if its too much select large or medium.

In Temporal Threshold, increase it between 20-50.

Create another node and add Special NR, select faster and here we raise the chroma 20 or 30
