When I make a flipbook from sprites I have a problem whith anti-aliasing

Hi all! I have a sprite with smooth edges, but when I make a flipbook from it, the edges become sharp.
How I can fix it?

If you go into the source image and change the texture space to 2D Unfiltered I think it should fix that.

Thank you! It was already 2d unfiltered but when I switched to “world”, the problem was solved. But what means this setting?
