Analog Clock

[Vikkes93]

Hi,

Im making an analog clock with a minute, second and hour handle.

hey shall rotate properly relative to each other. Its my first time using expressions and Im a bit lost. I want the time to speed really fast, for so slowing down and stopping completely.

Right now Im using this on z rotation:

time*5 on the hour handle

time*60 on the minute handle and

time*720 on the seconds.

Please, If someone could help me with accomplishing this I would be so grateful.

I don't quite understand what you're asking. Are you saying you want the hands to move relative to each other, but you want control over the speed at which they spin?

If so, just tie the rotation of the minute hand and the second hand to the hour hand and keyframe the hour hand's rotation.

I can make them move relative to each other, but not speed up, for so slowing down. How can I choose different speed?

As Michael said, parent Rotation property of two arrows to a third one (Master Arrow) and appropriately adjust expressions with simple math. Then you can either animate Master Arrow Rotation with keyframes and optionally expressions (moving keyframes along the timeline will result in clock 'speed' change):

or you can apply Slider Control effect onto the Master Arrow layer and animate its rotation speed via time value as you originally wanted:
