Working on a slow animation with several objects in motion. I want to caption each step in the machine’s operation. The caption needs to be visible for the duration of a mechanical process (a synchronized rotation, for example) and then turned off to make space for new captions of successive mechanical steps.
I watched a video that shows how to turn layers off and on, and I am trying to use this technique to turn off and on a series of DOT type captions that are each allocated a unique layer.
I gather from the video you are supposed to 1) show Bongo where to turn the layer OFF and then 2) show it where to turn the layer ON.
It kind of works, in a sporadic way, but it is not a reliable technique for me so far. To get a caption to turn on at time zero, for example, it seems you have bang the slider against the zero stop a few times manually, and only then hit the go arrow to play the animation. Otherwise the captions do not appear at all.
Is there somewhere a complete discussion of how to turn layers on and off? I am guessing the animation I saw, of a pyramid of pool balls, is not giving me the whole story.
For example, are the objects on the layer supposed to be selected as a first step? Or is this unnecessary? What should be the initial state of the layer, Off or On, before you press Animate?

Here is a file. The first caption is supposed to appear at zero and remain visible until 46. The second caption is supposed to appear at 23 and remain visible until 46. If I can learn how to make captions appear and disappear, I have several more captions to add.
Thank you for your insights. Michael
