first couple of sec's - fast forwarded intense part or the highlight of video then the actual video, you can just make a template and use the same one if that works for you doesn't take much time on any editor. (you can use adplexity, spypush etc to get the best working templates and landing pages, you can even rip em and use the best within minutes, that actually saves a lot of time and research (let me know if you are already having some target i will get it for you for free))
approach the other accounts for f4f , rt4rt, once you get to know they are good, approach with your main accounts.
You are warming up twitter does that mean manually or automated using anything?
