A raster is a rectangular grid of pixels (tiny colored squares) that make up digital images and video frames. Each pixel holds color and brightness data, and together they form the picture you see on screen.
Rasters define how digital visuals are structured. The size of the raster grid (number of pixels across width and height) determines resolution, and ultimately how detailed or sharp an image appears. All digital video is raster-based (unless vector-based graphics are involved).
Know your raster dimensions when setting up sequences, exporting, or resizing footage. Upscaling raster content beyond its native size can cause blurriness or pixelation.
Work in native resolution – Edit and render in the original raster size to avoid quality loss.
Check scaling – Scale raster graphics proportionally to prevent pixelation or distortion.
Match delivery specs – Ensure raster size (e.g., 1920×1080, 3840×2160) aligns with platform or broadcast requirements.
