For the simpler implementation with fixed transition time and one slider (using hold keyframes), slider on layer “controls”.

Position expression:

pos_array = [[2, 54],[-4, -174],[0, -12],[8, 190]]; // predefined positions array
tt = 10; //transition time in frames
cv = thisComp.layer("controls").effect("Slider Control")("Slider").value; //current slider value
tp = 0; // transition progress default
for (i=0; i

Basically the same matter as discussed here. No ready expressions, but the basic methodology is there.

If the transition time is always the same — which it would have to be if you use just a single slider — you can simplify this by looping back from the current frame for the number frames that cover the transition and checking if the hold keyframe value has changed during that time. If it has, you can calculate the progress between the two positions (read from an array) from how many frames back the value changed (in relation to the full transition time).

The streaks behind the cars could possibly be achieved in AE with a masked build-up effect, i.e. use echo on a layer which has just those parts that you want to streak masked out and tracked (perhaps with rotobrush), but you need to time warp the footage with pixel motion blend to generate a LOT more in-between frames to get those smooth streaks. Unfortunately it’s more complex than that, since the streaks move with the footage, they don’t just stay in the place they were in the original frame.

A very complex 3D tracked particle effect could possibly get that result as well. Using a layer emitter matched to the parts you want the streaks originating from (which also makes it possible to derive the color from the image) with particular and auxiliary particles for the strings and streams…

It is really a rather advanced effect.

You could duplicate the (pre)comp, put it under your box layer, fill with black and use minimax to expand the edges, methinks.

SoundKeys can do an accumulative build-up of values, so you should use that option to get the output keyframes.

Ok, my first question is why not do this in a single paragraph text box? Would be significantly easier to scale to fit screen.

Quite simply.

If you need to round the slider to integers, use Math.round(pick-whip-slider-value-here)

You would have to find the indices of the words in question: You can split the string to array with individual words and check each for a match to your “search” words.
