This is done in the effects used to place vertical videos into a horizontal video aspect ration. Plenty on the market, and I’ve made it myself in Motion, very easy. Based on the example you’ve given, here’s where I’d start.
You’ll create a Drop Zone, then make a Clone Layer of that below it. Stretch the Clone layer our, or enlarge it. Then apply a Directional Blur to that and crank it up really high. Publish the desired parameters. Publish as a generator, which is what I’d do. You could probably do this in some way as a Title that you can just drop on top of a clip for the same effect, also.
