Dear Dave,
Thank you for your both replies on here and on other forum.
I don’t think that this is a counting issue. Because when i open the file in photoshop and just save it. Then open it In after effects i get the real 480 x 854 resolution.
When I drag it to my layer it creates a composition with 853 x 479. If i change the composition to 854 x 480 it gets blurry.
In blended i can open it normally. It shows the right resolution. So for some reason if i open the file in AE the resolution is 1px less from each side.
My only option now is to make a small action script and batch open and save in exr again. I just tried on one and it worked but i truly wanted to know what’s going on.
thanks in advance
