Something like this can be achieved quickly and easily With any of the four large AI video subscriptions. Some come with a free trial. For a $100 one month subscription you could make Perhaps 1000 animations of this quality shown above. Alternatively you could produce an animation like this manually using two stock footage clips and some overlay variants in a program like da Vinci resolve. Set a textured white paper background as layer one add an abstract stock clip for the color falling as track two above it, Then add an adjustment layer as the third layer, Then drag the film grain effect and crank it up really high on that adjustment layer. If you're not looking for exactly what he did, Just go somewhere like videoblocks and buy a clip that looks good to you and then cut out the section you need. I think it's like $20 for a one month subscription where you can pick anything you want as much as you want.
Here's a sample of just some stock Instagram art I made on runway, Stuff like this doesn't take much work, Maybe 3 hours for this entire video from concept to finish product.
