How to animate nodes?

How would I animate nodes? Say if I want to make a Blurr-Gaussian node more blurry at one time in the timeline or etc?

Thanks for any help.
God Bless you. :slight_smile:

Generally, use the render preview to see the effect., spend some time experimenting with the adjustments to get a sense of what they do then at the beginning of your scene use one set of adjustments then later in time when you want the scene to get more blurry change the settings.
