Enhance AI-Generated Corporate Video

There is a 2 minutes AI generated video which needs to be further enhanced and make it more professional. Concept and content sequence remains the same and sondies the audio track. Only the visual part need to be enhanced to be fit for a corporate presentation.The expected outcome has to look natural in its make.

Sharing below the current video link.

In this video of 5+ minutes ,the middle portion already has a natural content. I want the other prefix and suffix to match the similar one.
