Description of algorithms version 12 and software version 14 in neural network-based video coding (NNVC)
Abstract
This document is version 12 of a description of algorithms and software for Neural Network-based Video Coding. Due to a lack of synchronization between the document and the software development, it corresponds with a software codebase released as NNVC 14. It includes the coding features and encoding methods implemented in NNVC software that are under coordinated exploration study by the Joint Video Exploration Team (JVET) of ITU-T VCEG and ISO/IEC MPEG as potential neural network video coding technology beyond the capabilities of VVC. The groups are working together on this exploration activity in a joint collaboration effort known as the Joint Video Exploration Team (JVET) to evaluate compression technology designs proposed by their experts in this area.
JVET-AM2019 Description of algorithms version 12 and software version 14 in neural network-based video coding (NNVC) [F. Galpin, Yue Li, Yun Li, D. Rusanovskyy, T. Shao, J. Ström, L. Wang] (2025-09-30)
New elements in text and software from notes elsewhere in this report:
- Decision: Adopt JVET-AM0135 EE1-2.1.
- Decision: Adopt JVET-AM0175 EE1-3.2 (non CTC, also provide training script).
It is noted that the list above may not be complete; if some adoption is missing that is recorded somewhere else in the meeting notes it shall also be considered included.
Remains valid – not updated: JVET-AK2020 Film grain synthesis technology for video applications ed. 2 (Draft 2) [W. Husak, P. de Lagrange, A. Norkin, A. Tourapis] (2025-03-14)
Note that draft 3 (JVET-AL2020, planned as output of 38th meeting) had not yet become available by the time of releasing this report.
