Layer Time and buffering

Duration: Specifies the time for an iteration of the animation that will be performed;

RepeatCount: Represents the number of iterations that the animation repeats. If the duration is 2,repeatcount set to 3.5 (three half iterations), then the full animation duration will be 7 seconds;

Duration and RepeatCount are all 0 by default. But this does not mean that the animation is 0 seconds or 0 times, where 0 represents only the "default", that is, 0.25 seconds and 1 times

BeginTime: Specifies the delay time before the animation starts. The delay here is measured from the moment the animation is added to the visible layer, which defaults to 0 (which means the animation executes immediately)

Speed: is a multiple of a time, the default 1.0, reducing it slows down the layer/animation time, and increasing it speeds up. If the speed of 2.0, then for a duration 1 of the animation, in fact, in 0.5 seconds time has been completed;

Timeoffset: Similar to BeginTime, but unlike the delay animations that increase begintime, increasing the timeoffset just makes the animation fast forward to a point, for example, for an animation that lasts for 1 seconds, Setting Timeoffset to 0.5 means that the animation will start from half of the place. Unlike BeginTime, Timeoffset is not influenced by speed. So if you set the speed to 2.0 and the Timeoffset to 0.5, then your animation will start at the end of the animation, since the 1-second animation is actually shortened to 0.5 seconds. However, even if the timeoffset is used to let the animation start at the end, it still plays a full length of time, the animation just loops around and then starts playing from the beginning
