Ask HN: How can I make automated videos from data of real estate I have in Mass?

I want to generate a descriptive slide show video (In 4K) ex: https://www.youtube.com/watch?v=rZM5jaU7YyE what this guy has done for Watches I want to do real estate properties list I have.

I have property details, photos, some have walkthrough videos too. I want to attach them to make a slideshow kind of video where the text is spoken as good quality voice using may be amazon or google voice API.

What kind of libraries I can use to work this out?

https://rocketium.com/is/quick-and-easy-bulk-video-maker-in-batches/ I saw this but it seems a bit costlier solution for the scale I am looking for.

I have to make more than 1000 videos. So any ready-made cheap solution? Or something where I can hire a dev and get it done?
