So it's not a bug, it's just a missing feature! Blender's Trim Curve documentation does have a warning that cyclic splines are not currently supported. Which tells me that at some point when they are supported, we won't need the work around in the video to disable the Trim Curve at the end of the animation duration. 🎉 Also, I later discovered that you CAN use the Sample Curve node to get unique positions for all points. I misinterpreted the documentation. The fact that it inputs and outputs fields should have been my clue. If you connect the Index field to the Sample Curve's Curve Index input, the Position output field will give you the factor's position for every spline in the Curve geometry input. No need for the Repeat Zone. You can use Domain Size to get the count of splines, use a Points node with that count, then plug the Sample Curve's Position field output into the Points node to set their positions.
Is there a reason for using colour ramp to drive the orb size, rather than a float curve? I guess it demonstrates another approach, but I always find that float curves are more intuitive.
No particular reason other than habit or preference. I tried adjusting it with the float curve and still prefer the color ramp. The color ramp let's you see the effect as you drag the stops around whereas the float curve you have to release the mouse button to see the change. I suppose it depends on the situation.
Thank you! You should be able to add a Math node after the Scene Time node to subtract some amount of seconds or frames so it starts in the negatives. Once it starts to go above 0 the animation curve will kick in.

Great stuff man! This could be useful for logo animations as well :)
Glad you enjoyed it! Yep a lot of the concepts apply as well.
Great work. I have a question: how can we use this method but presenting each letter after each other (like in your typing video)?
Underrated channel
This made my day. Thank you!
Excellent work!
Thanks a lot!
super cool tutorial
Thank you! Hope you learned some useful stuff from it.
Nice!! 🎉
Thank you! 😊

thanks @TiFiDesign good job!
Thank you! I'm glad you enjoyed it. :)
HI..awesome tutorial BTW . just a small doubt How to I Delay the Animation? like How can i make the animation Start after a Few Frames?
