I am trying to animate a vehicle coming to a stop and I want the tail lights to start glowing at a certain point. To have a realistic effect, I was using the compositing screen layout with more than 10 nodes and about 30 values and checkboxes. So, I was wondering if there is a way to keyframe all these values at once instead of clicking on each value and insert a keyframe.

    $\begingroup$ Although I have not done this many personally, I am aware that this type of thing is handled using drivers. Here is a tutorial I found. and some documentation on Blender manuals. Hope this helps to get you on the right track. $\endgroup$ – Jasun Thomas Apr 26 '17 at 21:16

  • $\begingroup$ @farhat2 I think you misplaced the animation nodes tag, maybe you want to have them separated as animation and nodes, because animation nodes is a (great) addon and your question doesn't ask anything about it. But if you want there is a way to answer the question using the animation nodes so I'll put it as answer for now $\endgroup$ – Pascal Nardi Apr 28 '17 at 16:12

You can use the Cycles Material Output node to control the strength of your emission shader where its value is controlled through an Animate Float node.

Node Tree

Where the Delay node controls the frame at which the animation will start.
