Hi,
I fail to see from the video what your problem is?
It seems to perform as continuous servo should.
The difference between an analog and digital servo is the internal control system, they are basically interchangeable.
A continuous servo is used as motor/wheel drives, RC yacht winches.
Position servos run at one speed if asked to go from 0 to 45 or make large excursions as the internal control system is made that way.
If a servo gets a 90 signal and it is at 0 and its your favorite and most expensive RC toy and its heading for the ground, then you would appreciate as fast as possible reaction.
You can make a positional servo move slow by sending incrementing signals,
eg 0 to 45, send 0 then 1 then 2 etc to 45.
or if a little faster 0 then 5 then 10 etc to 45.
You need to google how a RC servo works
