This post doesn't relate to the Shopify Script Editor App so I'd assume you've posted this in the wrong forum section by mistake. You'll get better responses if you post in a related section so I'm going to move your post elsewhere (why).
Since it looks like you're asking for people to help out on a paid job, moving this to the job board makes the most sense.
Do you want to record and palyback fuction?
Where are you planning to store this recorded videos on server or do you want to use a cloud service for that?
Add me on skype so that we can discuss in detail about scope of work.
