Clock Hands Rotating but I need a Slider Control or something to control speeds
on Jan 5, 2012 at 7:42:47 pm

I have a basic whimsical clock that has all 3 hands that will rotate from normal speed to as fast as I need it to go.

I can parent the hands together but what if I wanted to have a slider control that I could adjust that slider and change the speed of all 3 hands... ranging from normal speed up to whatever

I also need my "hour" hand to go all the way to 12. I can do that too and have the other hands follow

But a slider to adjust speeds of all 3 hands would be great

Currently my clock hands are at the 12 o clock mark. But what if I wanted to move my hour hand to start at 3 o clock and have the other hands follow?

I know the faster I adjust my hour hand, my second hand will be "flying". At any rate, any help that you might have will be grateful.

Thank You!

Controlling speed in AE is tricky. You're better off controlling the total degrees rotated. If you keyframe the slider to go from 0 to 360 your hour hand will go from 12 to 12 and you can ease it however you want.

Thanks Dan - I dont need to do variable speed - I just need to set it and forget it. I will duplicate the CLOCK comp 3 or 4 times for different speed of clocks.

Any tips on how I can link the 3 HANDS to one slider???

Thanks a million!

What a coincidence, I was just responding to a post by Dan (from 2 years ago) on a very similar topic (rotation speeds and expressions) when I noticed this thread. The post is at:

and might help you out a bit.

My response was regarding motion blur using this technique.

You could link the hour hand to the slider and use this for the minute hand:

thisComp.layer("hour").transform.rotation*24

and this for the second hand:

thisComp.layer("minute").transform.rotation*360

Yes, you CAN link all three hands to the one slider:

Create a null called controller_null with an angle control on it.

On your hour hand's rotation, put:

thisComp.layer("controller_null").effect("Angle Control")("Angle")

On your minute hand's rotation, put:

thisComp.layer("hour hand 2").transform.rotation*12

On your second hand's rotation, put:

thisComp.layer("minute hand").transform.rotation*60

Keyframe the angle control from (for example) 0 to 1 to get a 12 hour animation.
