Please rate/correct/suggest my editing plan with Camtasia

I know how to use Camtasia when it comes to the basics but have always wondered about making proper YouTube videos.

My plan:

- Clone my voice (ElevenLabs)
- Use ChatGPT to make YouTube video scripts, and to tell it to add timestamp editing points [more below]
- Sync my voiceover to the script
- Import the voiceover + script into Camtasia

I will upgrade Camtasia in order to access the TechSmith Premium Royalty-Free Image and Video Assets add-on libary. From here is where I get a little hazy as I'm unsure how you go about implementing the editing side of things?

One idea I had was to tell ChatGBT to add timestamp references so I know what time to add a new stock image/clip, if I do that it should save me time and save me having to play/stop my voiceover etc.

I would like to hear your thoughts about my above plan and to hear any feedback regarding improvments.

Thanks
