Evidence claims:
- [upstream_claim] README: dataset built from 4K HDR10 YouTube videos (10-bit, Rec.2020, PQ) and SDR counterparts: 1235 training pairs and 117 test pairs; original YouTube links provided because the authors do not hold copyright to distribute the videos; pretrained models via Baidu Netdisk/OneDrive. · locator: README, dataset and pretrained models · source: https://github.com/chxy95/HDRTVNet
- [sourced_fact] README points to HDRTVNet++ (arXiv 2309.04084) as the extended version. · locator: README, top notice · source: https://github.com/chxy95/HDRTVNet
- [sourced_fact] GitHub metadata: MIT, not archived, last push 2026-03-26. · locator: repository metadata · source: https://github.com/chxy95/HDRTVNet
- [upstream_claim] Research review verdict at export: reviewed (as of 2026-10-17). Recorded by the research pipeline, not a hub review outcome; evidence.review stays unreviewed until an independent reviewer records one.
