Hi,
The timeline ticks are an abstract notion of time. The ratio between a tick and a second is set up when the animation is rendered. You do not have to scale the keyframes.
In this model Flag bis.3dm (292.3 KB) the range reaching from tick 0 till 99 is rendered into a video of 1 second with a framerate of 25 frames-per-second.
The matter is comprehensively discussed in Problem registering multiple sequences - SOLVED
