Rough English translations as follows:
2:08 JYP: Uh, Mako--you're so friggin' cool! It's pretty much impossible to find any faults with you, so there's really nothing to evaluate.
2:15 JYP: I think the word "badass" is probably the most apt "evaluation" for you.
2:23 JYP: Mako, you were ranked 1st in the vocal evaluation, right?
2:27 Mako: Yes!
2:29 JYP: Do you know who sang the best today?
2:38 JYP: It was Mayuka.
2:42 JYP: --Was always frustrated, like--whichever song you perform on stage, you can't always give off the aura of a "good girl," y'know? That was always the most disappointing part about you, Mayuka. (T/N: the way they edited this, it cuts into JYP mid-speech, and I can't tell what that weird sound he made at the beginning of his sentence is)
2:52 JYP: That's why I told you in the Practice Room, "Please, show me who you really are!" Yeah... (T/N: as in her personality or "inner colour")
3:00 JYP: Mako is pretty much the best ranked/skilled performer amongst all the girls right now, and you did not lose out to her, Mayuka. (T/N: as in, Mayuka performed at a level roughly equivalent to Mako in this performance)
3:10 Mayuka: Heh... thank you very much~!
3:16 JYP: Miss Ayaka. Your dancing skills have leveled up so much!
3:20 JYP: When you were doing the zombie walking part, the angle/line of your arms was straight & true!
3:26 JYP: Your body line, arm line, leg line (T/N: JYP is referring to dance terms, namely the angle & form of Ayaka's body/arms/legs while dancing & how accurate/good they are) ...they were all precisely on spot!
3:34 JYP: Uh... Riku, today you were...
3:42 JYP: It's the first time that I feel like you remained stationary in your improvement. (T/N: as in, Riku's hit a plateau during this performance, whereas she was continually leveling up before)
3:47 JYP: You weren't able to quite reach my expectations based on your previous, consistent improvements in skill.
3:53 Riku: Understood...
4:03 JYP: Momoka, you are stuck in a rut...
4:09 JYP: Just to get it out, why do you think that's the case?
4:12 Momoka: As I thought, it's maybe too late for me...
4:17 JYP: A singer? Or even a Star--you definitely have the potential to become one.
4:23 JYP: It's a shame/waste for a talented person to be unable to realize their full ability, right? (T/N: realize as in attain or display)
