If that video is just CGI, why didn't they sped it up in the first place to look more realistic?
That shit was just video glitch. happens all the time with bad format.
You don't know nothing about thrust to weight ratio don't you?
that little toy rocket was just a few kilos, maybe a hundred at max hard to say without a scale. And it only had electronics on surface, there is no safety limit of the acceleration, it can accelerate with 20-30-50G and it won't fall apart. And: small rockets like that, fireworks and toys use solid fuel. It has a great thrust to weight ratio, but you can't adjust the thrust, and you have little or no gimbal on nodes, so your only control over the rocket is by control surfaces wich are great in atmosphere but useless mass in vacuum
And, if you ignite a solid fuelled rocket, then it is fuckin ignited! No way to stop it and restart. It burns like hell until it runs out of fuel! If you want to send humans in space, and you want them back in mostly 1 piece, then you have to test your engines. Ignite it several times, adjust thurst, gimbal the nodes, etc... So they sticked with liquid fuel. wich needs fuel pumps and etc, wich decreses the maximum thrust and the thrust to weight ratio. However it is a well controlled burn, it has a more higher ISP (specific impulse (effectiveness...) ) They still could accelerate faster tho, but they don't want to. Why? 1: because the faster you go in the dense lower atmosphere the more it will drag you. No need to waste a lot of fuel just to be 1-2 min faster. You can accelerate harder in thin air or vacuum without wasting your fuel. And the second reason: There are fuckin humans aboard! XD You can't give them 20-30 G because they will pass out and they will shiet out of their organs...
I hope I could answer some of your questions
