Evidence claims:
- [upstream_claim] README: audio-driven portrait animation accepted to ICLR 2025 with long-duration (scripts/inference_long.py) and high-resolution (scripts/video_sr.py) modes; showcases labelled 4K, including a 23-minute and an up-to-1-hour example. · source: https://github.com/fudan-generative-vision/hallo2
- [sourced_fact] README says the repository is MIT but the high-resolution feature is a modified CodeFormer whose use or redistribution must follow the S-Lab License 1.0; tested GPUs listed as A100, no VRAM figure. · source: https://github.com/fudan-generative-vision/hallo2
- [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.

Rights:
- code: license=MIT (plus S-Lab License 1.0 for modified CodeFormer component) hosting=restricted redistribution=restricted modification=permitted training=unknown · MIT for the repository per page; the super-resolution component is bound to S-Lab License 1.0 whose text was not read. · evidence: https://github.com/fudan-generative-vision/hallo2
- model_weights: license=unknown hosting=unknown redistribution=unknown modification=unknown training=unknown · Checkpoint license not stated on the page; upstream components (Stable Diffusion v1.5, AnimateDiff motion module, wav2vec) carry their own terms.
