Scrolling background loop

[nadrojxinnam]

Hi there, i'm trying to make an animation with the background scrolling sideways in a constant loop . . I've tried a few tutorials on youtube but can't figure it out properly. Any suggestions? The image below is the bacckground

Before you even try this, I thing you need to get a wider background.  That brown door going by every few seconds is going to get mighty boring.

Thanks for the reply, i've made it longer and a bit more detailed, could you advise me on how i could just loop this image scrolling sideways if possible? Thanks

Do what foughtthelaw says and you should be good!

you want the "offset" effect. just apply it to the layer with the door and mess with the x value.

This is the correct answer. There’s no need to make the layer wider. Just apply the Distort > Offset effect. The easiest way to get it to loop perfectly is to keyframes it at the beginning of the comp. move the time marker to the end. Right click on the property value and Go to Edit Value. Change the measurement units to “Percentage of composition or layer”. Then if you animate in multiples of 100 percent it should perfectly loop
