Your video responses are recorded. You might give it away, if you would read from the screen. I mean, it might get reflected. Just stay cool and say your revert. Instead of an ideal combination of words, it would go well if you say whatever you say in a relaxed and friendly manner. If you start a sentence differently than you had planned, modify it accordingly. A glitch or a stutter here or there may be ok, if the remaining portion went fine and in relaxed manner. You should also not reproduce the exact memorized sentences. Abstain from it absolutely. It might be difficult to not that. Try your best not to. Good luck. 👍
Correction: It might be difficult to manage* that.
