}Evidence claims
- [upstream_claim] README: input a green screen frame (with an alpha hint); the network separates foreground from the green screen and predicts true colour for each pixel including transparent ones; reads and writes 16-bit and 32-bit linear float EXR for Nuke, Fusion or Resolve. · locator: README, intro and features source
- [upstream_claim] README: designed on a 96 GB VRAM workstation; most recent build said to work on 6-8 GB VRAM and most M1+ Macs; optional GVM alpha-hint generator needs ~80 GB VRAM and VideoMaMa originally 80GB+; alpha hints can come from other tools. · locator: README, hardware requirements source
- [sourced_fact] LICENSE 'Corridor Key Licence 1.0' = CC BY-NC-SA 4.0 plus additional terms: commercial-project use permitted, but no repackaging/resale, no paid API or inference service, and commercial software integration needs separate terms; additional terms take precedence. · locator: LICENSE, Additional Terms 1-2 source
- [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.
