How to make a cycle for some layers in Motion 5 timeline?

Question

I've just started to study animation in Motin 5...
Maybe somebody knows how to select some frames and make them repeating several times?

Answer 1

The animation group has to be trimmed to the length of the animation. The clone will automatically be exactly that length when created. In the Inspector > Timing, you need to set the End Condition (2nd parameter from the bottom) to Loop then retime (stretch) the clone layer to as long as you need in the project timeline.  You need to set it in that order: set timing to loop, then stretch the time length of the clone (you should see "notches" in the timeline under the canvas marking the cycle length.) You can't do it the other way around (stretch clone then retime) [well, you can, but it's a lot more work to fix it afterwards.]
If the length of the animation is the entire project length, then you can use a clone to speed it up and loop by also changing the speed to greater than 100% (multiples of 100 recommended), setting the end condition to loop and dragging out the length of the clone in the timeline.
It is very much worth the effort to learn how to use clones... They can be so useful for so many things. For instance, you can create an emitter that "explodes", clone it, then use the timing to reverse it so it *implodes*, etc...  Clones can also behave as an "inline" image sequence which can be emitted or replicated and have random frames taken out of the sequence -- or to play the animation for each instance of the emitted or replicated source...   And this one even boggles my mind a little: clone frames can exist anywhere in time, even before the animation is actually executed in the project.  ... and the list goes on...
