It typically uses a standardized video compression algorithm, most commonly based on discrete cosine transform (DCT) coding and motion compensation. A computer software or hardware component that compresses or decompresses a specific video coding format is a video codec.

Feb 3, 1998 · EE Times explores different algorithms for video compression and includes on overview on JPEG, MPEG and H.261. Visit the article.

• Video compression – Exploit temporal dimension of video signal • Prediction – Generic (MPEG-type) video coder architecture • Current video compression standards – What are they? – What do the standards specify? • Brief overview of H.264 / MPEG-4 AVC video coding standard

Video compression algorithms look for spatial and temporal redundancies. By encoding redundant data a minimum number of times, file size can be reduced. Imagine, for example, a one-minute shot of a character’s face slowly changing expression.

Nov 11, 2024 · Video compression algorithms use both inter-frame (between frames) and intra-frame (within a frame) compression techniques. Inter-frame compression relies on temporal prediction and motion compensation, while intra-frame compression exploits spatial redundancies within a single frame.

Video compression in digital video, enabling efficient storage, transmission, and consumption of content across a wide range of devices. By leveraging the right algorithms and techniques, video compression helps reduce file sizes while maintaining acceptable visual quality.

May 5, 2022 · While many different algorithms exist to encode video (such as MPEG-2, H.264/AVC, H.265/HEVC, VP9, AV1, etc), most of the popular codecs in use today follow a common set of principles which are introduced in this blog post.

Dec 23, 2024 · Advanced video compression algorithms play a crucial role in reducing video data size and improving transmission and storage efficiency. These algorithms, utilizing sophisticated and optimized techniques, have introduced new standards that …

Mar 21, 2025 · Video compression works by using codecs like H.264, HEVC, and AV1 to reduce file sizes while preserving quality. H.264 balances efficiency and compatibility, making it a go-to for streaming. HEVC offers better compression for higher resolutions but requires more processing power.

In other words: The main idea today: use an algorithm to predict what a future pixel should be, then store a description of the algorithm and the residual of the prediction. Stanford CS348K, Spring 2023
