2 Questions: How do I do voice over ai and how do I correct iPhone video over exposure?

Hi all,

Question 1: Can I create an AI voiceover using Adobe Premiere Pro and keep it aligned with the video?

We created video tutorials and planned to use AI for the audio direction. I did a trial run using another AI audio tool with AI video. However, after importing the audio only into Adobe Premiere Pro, it does not align with the video timeline.  Worse comes to worse, I can always clip the sections of the audio and make the audio sections align with the video timeline. But that's a lot of work because there are many video clips I have to edit in Adobe Premiere Pro. Any suggestions on resolving this issue using an Adobe Product will significantly help!

Question 2: I used an iPhone with a RingLight to take the videos. Unfortunately, after exporting the video as an MP4, the video is very, very bright.  How do I resolve this issue?

Thanks for your help!!!
