Raster vs Vector Images: Which Format Fits the Job?
Raster images store a grid of pixels; vector graphics describe shapes and drawing operations that can be rendered at many sizes.

Generative AI uses patterns learned from existing data to create text, images, video, audio, or code. This beginner-friendly guide explains how it works, where it is used, and…
A motion prompt is an instruction that describes how a subject, camera, or scene should change over time in generated video.
Image-to-video AI generates a sequence of frames conditioned by a starting image and instructions, proposing motion rather than revealing a recorded future.
Frame rate is the number of video frames presented per second; it affects motion sampling, duration, editing, and delivery compatibility.
Aspect ratio is the proportional relationship between width and height, such as 16:9, 1:1, or 9:16.
Pixel dimensions describe how many pixels an image contains; print resolution describes how densely those pixels are placed in physical output.
An image mask controls which parts of a layer are visible while preserving the original pixels for later adjustment.
An alpha channel stores opacity separately from color, allowing each pixel to be fully visible, partly transparent, or fully transparent.
Create a transparent background by isolating the subject, preserving partial opacity around soft edges, exporting to PNG, WebP, or AVIF, and checking the result on light and dark…
