eVc2

eVc2, sometimes written eVC2 or eVc-2, is a designation found in discussions of video coding that may refer to more than one concept. The most commonly cited usage is Enhanced Video Coding 2 (eVC-2), a proposed successor within the broader family of Enhanced Video Coding (eVC) efforts that aimed to improve coding efficiency beyond earlier eVC work and in the period surrounding the development of modern video codecs. In this context, eVC-2 is described in sources as seeking higher compression for a given video quality, with attention to scalable profiles and broader applicability.

However, there is no single formal ISO/IEC or ITU-T standard officially published under the name eVc2. Published specifications and widely recognized standards do not converge on a definitive eVC-2 specification, and public documentation is limited. Some references to eVC-2 appear in academic papers, industry discussions, or vendor notes as part of historical discourse about alternate or transitional video coding ideas, rather than as an adopted standard with broad interoperability guarantees.

In addition, the term may be used informally to describe extensions or variants related to VC-2 (a video compression approach standardized by SMPTE) or to other agile or proprietary developments related to enhanced coding techniques. This usage is even more variable, and it does not reflect a single, formal specification accepted by major standardization bodies.

As a result, information about eVc2 varies by source, and concrete implementations or deployments are not widely documented. The term is largely of historical and researching interest rather than representing a widely adopted, standardized codec in current consumer or broadcast ecosystems.
