AVIF seems to be based on HEIF ??

Whatever Sony comes up with will certainly be widely supported, just not by legacy programs and/or gear.

Any thoughts? Or did I misunderstand his comments?

thanks

AVIF seems to be based on HEIF ? Also I'm wondering about patents and IP issues...

The AV1 Image File Format (AVIF) is a specification for storing images or image sequences compressed with AV1 in the HEIF file format.[140] AVIF files conform to the HEIC specification and support features like High Dynamic Range (HDR) and wide color gamut (WCG).

Patent claims

In March 2019, Luxembourg-based Sisvel announced the formation of patent pools for AV1 and VP9. Members of the pools included JVC Kenwood, NTT, Orange S.A., Philips, and Toshiba, all of whom were also licensing patents to the MPEG-LA for either the AVC, DASH, or the HEVC patent pools.[137][138] Sisvel announced it would demand €0.32 for display devices and €0.11 for non-display devices using AV1, but would not seek royalties for encoded content. At the time of the announcement, a list of patents owned by Sisvel was not publically available. However, Sisvel's CEO stated in an interview that such a list would be posted on Sisvel's website before any licensing demands were sent out.[139][137]
