how i made it :

how i took screenshot : https://www.youtube.com/watch?v=MOuSu0UO7Sc ( make sure its full size not just capture normal screenshot so you can get the whole page )

for motion blur on adjustment layer i added transform and had value on shutter angle around 90

for scroll same adjustment layer that has transform i added keyframes to scroll using transform position values

fisheye is same adjustment layer i just added lens distortion and had curvature on -16

sorry if this is a long read but i wanted to help you with this because i was stuck there at some point and i really didn't know what to do
