There is a lovely animation effect on page 1 of this interactive file Published Online:
The photos in the background are moving slowly right to left. What animation effect was used here?
My attempt is a little 'jerky' in some places as my images scroll over and it stops short of showing all of the images. I used Fly in from Right with a 20 sec duration. I'm not sure which to select in the Animate area, i.e., "From Current Appearance" or "to Current Appearance/Location". I have fifteen images grouped and I'd like them to continuously scroll then repeat.
I would do this as follows:
-- group images in InDesign
-- set left side of group on left side of page
-- choose preset "Move left."
-- select motion path and extend to the left (turn on animation proxy to make sure group ends on right-most image)
-- increase duration
Here's a screen shot of the setup for a single graphic, the example is here: https://indd.adobe.com/view/2da33f1b-9d4e-4a49-bdde-45ce7fd97b1e
As for looping, that's hard to do. But frankly, will anyone stay on the page that long? I've viewed the sample file you gave many times and today is the first time I've sat through to the end; it doesn't loop.

Did you try the loop check box?
Thank you Diane, you are correct -- I don't need it to loop.
Using your direction below I am making progress but after every few images that go by, it stops for a quick micro-moment and carries on again, like it hit a bump. Is that something I can adjust in the motion path? I need to get used to moving/altering the motion path using the 'Direction Selection Tool'.
I do see the animation proxy gray area but I don't think it's in the right area. I don't understand how to make sure it's in the right place. I assume its location is determined by the motion path. It's something I need to play with.
Also, to confirm... I don't need to adjust anything in the Properities area, i.e., "from/to Current Appearance/Location/origin point', correct?
