Might be a similar problem and I'm even sure it exists even during the RAM preview unless you really preview the whole 3 minutes from the beginning. Otehr than that MP rendering messes with expression evaluation, so turn it off.
Thank you for your very prompt reply.
I've been thinking the same thought that maybe it was timed.
However, I have noticed that if I change the speed, this will also change where scrolling stops.
However, I am not sure how I get around it ...
And you're right, I have not seen the whole movie in raw preview from start to finish
Maybe I somehow reset the speed and then again back to the starting point ...!
MP rendering is disabled.
Thank you once again!
Mylennium, I wasn't sure he was using expressions here.
Perhaps I'm missing something?
I am now sure that it is when I change the speed of the one autoscroll.
I have two backgrounds with auto scroll.
One auto scroll is set to speed 100.0 and works perfectly whole movie through.
The second is set to -230.0 and it is the one who does not continue throughout the film through.
However, I am very unsure of what I here can do to fix it.
I only use Animation Preset Auto Scroll, nothing else .... if that's what you think...
The backround scroll uses a simple expression on the tile center property of the Motion Tile effect. You would simply reset it suitably using the method explained on my page:
offset = effect("Autoscroll - horizontal")("Speed (pixels/second)") * (time-inPoint) * (100/scale);
reset=thisLayer.width*10; //reset after 100 times the width has been scrolled
[(thisLayer.width/2 + offset)%reset, thisLayer.height/2]
Well, I've got it working and understand it in context!
I say thank you so much for your help!

Ah yes, got it. thanks mylenium.
Dear Mylenium I know it's a old thread but it's really help me alot, I am newbie in AE, don't know anything. Actually i need to make a horizontal scroll in 30 minutes video. I made a pic in jpg 6000px (Width) 40px (Height). Your code helps me to make loop.
