Cheap and best video analyzing LLM for Body-cam analyzing project.

As the title suggests, I am currently working on an employee management software for manufacturing industries where I am supposed to use body-cam footages to make a streamlined data report with pie charts and heat maps and stuff.

I am stuck at finding a good model with good pricing. I need help in two ways :

1 - What do you guys think is the best models for this purpose ? ( I am currently looking into Gemini 2.5 flash )

2 - Do you guys think this project is actually possible :(
