képkockák

Képkockák, singular képkocka, are the basic temporal units of film, video and animation. Each képkocka represents a single still image in a sequence, and when these images are displayed in rapid succession, they create the perception of motion.

Technically, a képkocka contains the color information for every pixel in a frame, typically stored in a color space such as RGB. The resolution and aspect ratio of a képkocka determine how much detail the image holds, while compression techniques reduce the data required to store or transmit many consecutive frames. The term is commonly used across video production, broadcasting, and computer graphics to distinguish individual frames from the continuous stream of frames that compose a video.

Frame rate measures how many képkockák are shown each second. Common standards include 24 frames per second for traditional cinema, 30 fps for many television formats, and 60 fps or higher for high-motion content and interactive media. In video encoding, frames may be categorized by prediction type, such as I-frames (intra-coded frames) that contain a complete image, and P- or B-frames that reference other frames to save data.

In practice, képkockák are central to editing, compositing, and playback. They are analyzed for timing, motion, and visual quality, and are manipulated in post-production to achieve effect, rhythm, or synchronization with audio. The concept is fundamental across filmmaking, animation, video games, and digital media workflows.
