![]() The pixels of a layer aren't positioned directly on the pixel boundaries Position and effect control points, to a precision of 1/65,536 ofĪ pixel. For example, if a Position value goes from atĪ keyframe at time 0 to a value of at time 1 second inĪ 25-frames-per-second composition, then the value at frame 1 isĪfter Effects calculates all spatial values, like This allowsįor smooth animation, as a value is interpolated from one keyframe Integer values they can have fractional values, too. Position and Anchor Point) in After Effects are not restricted to Bicubic sampling helps more for scaling up than it does for scaling down. Bicubic sampling tends to be the best option in cases where transitions from one color to another are more gradual, as is the case with nearly all real-world photographic images, but not necessarily for sharp-edged graphics. It’s rather easy to see artifacts with bicubic sampling in some circumstances, such as ringing and overshoots at a hard transition from one color to another. The default keyboard shortcuts for setting the sampling method for selected layers are Alt+B (Windows) and Option+B (macOS) for Best/Bilinear and Alt+Shift+B (Windows) and Option+Shift+B (macOS) for Best/Bicubic.īicubic sampling is somewhat more processor-intensive than bilinear sampling, and bicubic sampling is not the highest-quality choice in all cases. This per-layer setting determines how pixels are sampled for transformations such as scaling.
