This works rather well except for two things:
1) I need to have them moving continuously for up to 60 seconds without gaps. I can loop it but then, gaps. Or I can make the string really long and mask it but this makes a mess. And if I use ECHO, I can’t zoom ( Think)
2) this one’s odd , but In AE 2024, it seems that I need to adjust the Last Margin to get it to work, while in earlier versions on another machine it’s the First Margin that does it.
