I recently wanted to start creating amv again after more than 10 years of break!
And I came across this video that caught my interest to the fullest: https://www.youtube.com/watch?v=SbRvE42MlRY ("Friends" from Ben Raki)
I'm desperate to know what effect he used at those times: [0:15 - 0:16] and [0:16 - 0:17].
I have been looking, but unfortunately I can't find anything.
Do you have any idea what that could be? A link to a tutorial?

I'm on Premiere Pro et After Effects
Thank you very much.
