Inquiry About a Video Effect Seen in an Euro 2024 Tweet

Hello everyone,

My name is Maxence. I'm writing to you because I have a question about an effect I saw in a video. After watching a tweet from Euro 2024 that included a video with a very nice effect, I'm wondering how to create it myself using the software After Effects.

I am attaching the link to the tweet so you can see the effect in question. The effect starts at 4 seconds and ends at 7 seconds in the video. I would like to know if this effect has a name and how to reproduce it.

For those who do not wish to access the tweet, I have isolated the sequence of the effect.

Thank you in advance for your help. I look forward to your responses.

Best regards,
Maxence
