Bilinear Interpolation

What is bilinear interpolation and when is it utilized in motion graphics?
GLOSSARY
Bilinear Interpolation is a technique used in image processing and motion graphics to interpolate values between pixels, ensuring a smooth gradient when scaling images or video. It calculates the value of a new pixel based on a weighted average of the four nearest pixels in the original image, improving the quality of resized or transformed visual content.
When scaling up a logo for a motion graphic intro, bilinear interpolation ensures that the edges of the logo remain smooth and not pixelated, preserving the logo's visual integrity even at higher resolutions.
Technical definition
The process involves averaging the color values of adjacent pixels and assigning the result to the new pixel, effectively blending the pixels to minimize abrupt color changes. This is especially important in motion graphics where maintaining visual quality across varying resolutions is key.
