Screen Recording Editing for Personal Use

I have a screen recording that I need edited for a friend. The video replacing some of the original content. Specifically, I need certain pictures and texts replaced throughout the video. As well editing the time. It shows my Bestfriend worked and I need it to look like she did not work.

Ideal skills for this project include:
- Proficiency in video editing software
- Ability to replace content seamlessly
- Attention to detail to ensure the video flows well
