'''에센셜 비디오 코딩'''(Essential Video Coding, '''EVC''') 또는 '''MPEG-5'''는 MPEG 워킹 그룹 11의 130차 회의에서 결정에 따라 2020년 4월에 완성된 현재의 비디오 압축 표준이다.<ref name="ibc" /><ref name="meeting125" /><ref name="intro" /><ref>{{웹 인용|title=MPEG-5 EVC gets final approval |url=https://www.csimagazine.com/csi/MPEG-5-EVC-gets-final-approval.php |website=CSImagazine.com |access-date=6 May 2020 |ref=1}}</ref>

이 표준은 로열티가 없는 하위 집합과 개별적으로 전환 가능한 향상된 기능으로 구성된다.<ref name="meeting125" /><ref name="intro" /><ref name="req" />

XEVE(eXtra-fast Essential Video Encoder)<ref>{{웹 인용|url=https://github.com/mpeg5/xeve|title=eXtra-fast Essential Video Encoder (XEVE)|date=January 9, 2023|via=GitHub}}</ref>는 자체적으로 빠른 오픈 소스 EVC 인코더로 설명된다. C99로 작성되었으며 EVC의 기본 프로필과 기본 프로필을 모두 지원한다. 해당 라이선스는 커스텀 3절 [[BSD 허가서]]이다.

== MPAI-EVC ==
MPAI는 기존 도구를 AI 기반 도구로 개선하거나 교체하여 EVC의 성능을 크게 향상시키는 것을 목표로 하며, EVC의 기본 프로필보다 최소 25% 향상된 성능을 달성하는 것을 목표로 한다.<ref>{{웹 인용|title=AI-Enhanced Video Coding (MPAI-EVC) |url=https://mpai.community/standards/mpai-evc/mpai-evc-evidence-project-status-report/ |website=Moving Picture, Audio and data Coding by Artificial Intelligence}}</ref><ref>{{웹 인용|title=Basic Applications, Technologies and Benefits for Video Coding by means of Artificial Intelligence |url=https://mpai.community/wp-content/uploads/2022/03/HPA-V1.6_.pptx |website=mpai.community/news/presentations/#ShortPresentation|access-date=21 September 2022|date=23 February 2021}}</ref><ref>{{웹 인용|title=Video Basic Applications, Technologies and Benefits for Video Coding by means of Artificial Intelligence |url=https://platform.wim.tv/embed/?vod=33d669d3-4b28-4db9-b220-2c6fda5dc19d |website=mpai.community/news/presentations/#ShortPresentation|access-date=21 September 2022|date=23 February 2021}}</ref>
