This is my first go at asking a video production related question...

I have a programming / data science background.

I have about 30,000 spatial co-ordinates (i.e x , y coordinates) These have come into existence over about 15 years. I want to animate this.

So, I need a programmatic approach - there are just too many points.

Also, when each point appears...I want it to initially appear at say 100% opacity and then over about 15 frames fade to about 30% opacity.

What tool is the best to do this in...?

I am not sure if After Effects has sufficient programatic control..?

What about Flash..? (i.e Adobe CC Animate).

Eventually, I want this animated series of points to be a layer and I will stick it on top of a base map. And do some other stuff. So eventually, the layers will be composited in After Effects.

What tool should I use to create this animation...?

Thanks,

Mark
