According to my research, the common expression is "they burst into laughter".

However, I came across a video, and at 4:44, they say “then they burst into laughs”. The people in the video speak like native speakers.

Is it correct to say "They burst into laughs"?

    It makes sense but it is not idiomatic. The grammar and punctuation in that video are frequently incorrect. Jul 18, 2021 at 6:30

    @Tom - why would you expect anything different? They just want clicks. They don't want negative comments. They are not there to help you. Jul 18, 2021 at 11:33

    WOA looks like a very low quality site created by non-native people. Jul 18, 2021 at 11:36

Idiomatic expressions would be:

  • Burst into laughter
  • burst out laughing

"Burst into laughs" is not idiomatic. Don't be surprised when native speakers mix up their idioms. That video doesn't seem like a professional production, anyway - I skipped through it and heard at least two other mistakes.
