Versatile Video Coding

Versatile Video Coding is a science topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Versatile Video Coding rather than just read about it. In short: Versatile Video Coding (VVC), also known as H.266, ISO/IEC 23090-3, and MPEG-I Part 3, is a video compression standard finalized on 6 July 2020, by the Joint Video Experts Team (JVET) of the VCEG working group of ITU-T Study Group 16 and the MPEG working group of ISO/IEC JTC 1/SC 29. It is the successor to High Efficiency Video Coding (HEVC, also known as ITU-T H.265 and MPEG-H Part 2).

Key takeaways

  • Versatile Video Coding belongs to science; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Versatile Video Coding to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Versatile Video Coding from memory before moving on to harder problems.

Reference excerpt

Versatile Video Coding (VVC), also known as H.266, ISO/IEC 23090-3, and MPEG-I Part 3, is a video compression standard finalized on 6 July 2020, by the Joint Video Experts Team (JVET) of the VCEG working group of ITU-T Study Group 16 and the MPEG working group of ISO/IEC JTC 1/SC 29. It is the successor to High Efficiency Video Coding (HEVC, also known as ITU-T H.265 and MPEG-H Part 2). It was developed with two primary goals – improved compression performance and support for a very broad range of applications.

Concept In October 2015, the MPEG and VCEG formed the Joint Video Exploration Team (JVET) to evaluate available compression technologies and study the requirements for a next-generation video compression standard. The new standard has about 50% better compression rate for the same perceptual quality compared to HEVC, with support for lossless and lossy compression. It supports resolutions ranging from very low resolution up to 4K and 16K as well as 360° videos. VVC supports YCbCr 4:4:4, 4:2:2 and 4:2:0 with 8–10 bits per component, BT.2100 wide color gamut and high dynamic range (HDR) of more than 16 stops (with peak brightness of 1,000, 4,000 and 10,000 nits), auxiliary channels (for depth, transparency, etc.), variable and fractional frame rates from 0 to 120 Hz and higher, scalable video coding for temporal (frame rate), spatial (resolution), SNR, color gamut and dynamic range differences, stereo/multiview coding, panoramic formats, and still-picture coding. Work on high bit depth support (12 to 16 bits per component) started in October 2020 and was included in the second edition published in 2022. Encoding complexity of several times (up to ten times) that of HEVC is expected, depending on the quality of the encoding algorithm (which is outside the scope of the standard). The decoding complexity is about twice that of HEVC. VVC development has been made using the VVC Test Model (VTM), a reference software codebase that was started with a minimal set of coding tools. Further coding tools have been added after being tested in Core Experiments (CEs). Its predecessor was the Joint Exploration Model (JEM), an experimental software codebase that was based on the reference software used for HEVC. Like its predecessor, VVC uses motion-compensated DCT video coding. While HEVC supports integer discrete cosine transform (DCT) square block sizes between 4×4 and 32×32, VVC adds support for non-square DCT rectangular block sizes. VVC also introduces several intra-frame prediction modes based on these rectangular DCT blocks to provide improved motion compensation prediction.

History JVET issued a final Call for Proposals in October 2017, and the standardization process officially began in April 2018 when the first working draft of the standard was produced. At IBC 2018, a preliminary implementation based on VVC was demonstrated that was said to compress video 40% more efficiently than HEVC. The content of the final standard was approved on 6 July 2020.

Schedule October 2017: Call for proposals April 2018: Evaluation of the proposals received and first draft of the standard July 2019: Ballot issued for committee draft October 2019: Ballot issued for draft international standard 6 July 2020: Completion of final standard

Licensing To reduce the risk of the problems seen when licensing HEVC implementations, for VVC a new group called the Media Coding Industry Forum (MC-IF) was founded. However, MC-IF had no power over the standardization process, which was based on technical merit as determined by consensus decisions of JVET. Four companies were initially vying to be patent pool administrators for VVC, in a situation similar to the previous AVC and HEVC codecs. Two companies later formed patent pools: Access Advance and MPEG LA (now known as Via-LA). Access Advance published their licensing fee in April 2021. Via-LA published their licensing fee in January 2022. Companies known not to be a part of the Access Advance or Via-LA patent pools as of May 2025 are: Apple, Broadcom, Canon, Ericsson, Fraunhofer, Google, Huawei, Intel, Interdigital, LG, Maxell, Microsoft, Nokia, Oppo, Qualcomm, Samsung, Sharp and Sony. Access Advance promotes a standalone VVC licensing program under the name of VVC Advance, while Via-LA is promoting a combined HEVC/VVC licensing program; until April 2024, Via-LA was licensing VVC standalone. In December 2025 Access Advance acquired Via Licensing Alliance's HEVC and VVC patent pools but that still doesn't resolve the licensing situation because multiple companies beyond the former two patent pools administrators hold patents for the codec. Acquired Via-LA patent pools became known at Access Advance as VCL Advance but patent, licensor and licensee lists remain hosted on Via-LA websites.

Adoption

Worked examples

Example 1 — a first encounter with Versatile Video Coding

Start with the simplest possible case. Write down what Versatile Video Coding claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Versatile Video Coding before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Versatile Video Coding ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Versatile Video Coding

In research
Versatile Video Coding appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Versatile Video Coding in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Versatile Video Coding is common in secondary-school and first-year university syllabi. It links to neighbouring topics H.26x, MPEG, Open standards covered by patents, so understanding it makes those chapters shorter.
In everyday life
Look for Versatile Video Coding outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
