Scroll a long image in a fixed box

Hello everyone!

I’m trying to make an animation where box in fixed position has an image also this box works as a frame. While scrolling this image goes from a start to an end. So i faced with a problem in a mobile and mobile land scape. I couldn’t figured out how to make it works in a narrow screen height and tall screen sizes. I can’t set a right move distance either too much or too little depend on screen height. Hope i explained clear :grinning:

Thanks in advance
