Rough English translations in progress:
1:42 JYP: Miss Akari...
1:45 JYP: When I first met you, I thought to myself, "Wow, I've found someone worthy who I really want to produce for and mentor!"
1:58 JYP: And because I had such high expectations for you in my mind, I kept getting disappointed again and again... until you hit rock bottom and ranked in 13th place.
2:09 JYP: It was a really frustrating and sad experience. I thought, "Ah, did I make a mistake?"
2:21 JYP: But today, Miss Akari, you did so well that you stood out to me the most.
2:36 Akari: Thank you very much...!
2:43 JYP: What stood out in particular was your dancing.
2:47 JYP: It really felt like a shining star (T/N: pretty sure JYP means star as in celebrity, but this descriptions works in a figurative sense, too) was dancing around on stage...
2:55 JYP: ...and I was happy to know that "Ah, I didn't make a mistake."
3:03 Akari: Thank you very much...!
3:10 JYP: Miss Riria, uh, because you kept falling short of my expectations during your previous performances, you haven't had a single chance to be praised by me, right? Except that one time near the beginning of this whole show, correct?
3:19 Riria: Yes.
3:21 JYP: Well, you've improved greatly today.
3:25 Riria: Thank you very much...!
3:32 JYP: I really want to praise you for your singing--a group needs someone who can hit those high notes with a powerful voice like Nina, but what a group also needs is someone to sing all the other parts in a stable, reliable fashion. And you performed that role admirably, Riria.
3:45 JYP: Your voice had real strength behind it and felt rich/vibrant. During that situation-- (T/N: based on his intonation & how they edited this scene, JYP doesn't really get to finish his sentence before it cuts away)
