Temporal anti-aliasing can also help to reduce jaggies, making images appear softer. The resulting stop-go motion is a temporal form of jaggies; formally, a form of aliasing. Jaggies should not be confused with most compression artifacts, which are a different phenomenon. Jaggies are stair-like lines that appear where there should be "smooth" straight lines or curves. In addition, jaggies often occur when a bit-mapped image is converted to a different resolution. Jaggies occur due to the "staircase effect".
