JVET-AL0013 JVET AHG report: Film grain technologies (AHG13) [W. Husak, P. de Lagrange (co-chairs), A. Duenas, X. Meng, A. Segall, G. Teniou, A. Tourapis (vice-chairs)]

This period was slow with no meetings or discussions held.

From the previous meetings, the following five items should be in the second edition:

• Updated TR text to fix errors and clumsy wording
• Updated tools for the TR
• Video test sequences specific to film grain to be added to the TR
• Metrics – discussion and/or survey of available techniques or metrics
• Subjective testing of Film Grain

The following are worthy of discussion for the second edition:

• Conformance – this is interesting due to being an SEI
• Analysis – preprocessing analysis (parameter estimation)

These are additional topics for consideration and discussion:

• EG/RP (?) – What would be useful information for guiding usage? (guidance document)
• Future parameters and signalling – not a v2 topic
