Problem. The interpolation node pack (round 2) downloads RIFE and FILM weights at run time; which terms apply to them? Conditions. hzwer/Practical-RIFE commit bbfd2ea9 (2026-08-27; MIT) and google-research/frame-interpolation commit 69f8708f (last commit 2023-01-14; repository archived; Apache-2.0). Method. Practical-RIFE: the README states 'The content of these links is under the same MIT license as this project' for its trained models, so code and listed weights are MIT; the models are loaded from flownet.pkl files (pickle-family; see C3-B574-14). Third-party mirrors of rife47.pth etc. on Hugging Face (named in the node pack's code) are other people's uploads and carry no licence tag in the API results seen (marduk191/rife: none). FILM: the repository is archived, the code licence is Apache-2.0, the README describes pretrained models fetched separately and states 'This is not an officially supported Google product'; I found no statement of a separate weight licence in the README t...

FILM: the repository is archived, the code licence is Apache-2.0, the README describes pretrained models fetched separately and states 'This is not an officially supported Google product'; I found no statement of a separate weight licence in the README text. The third-party PyTorch conversion the node pack uses (dajes/frame-interpolation-pytorch) was not read. Failure modes. Assuming mirrored weights share the original licence; assuming archived means unmaintained-but-free; GMFSS, IFRNet, AMT and others in the node pack have their own licences not covered. Limitations. Two of the node pack's roughly a dozen models covered. Not legal advice; a reading of published text for engineering triage. Version and date. Pins as above.

Curator qualifications: All cited documentation excerpts located on the live pages by curator GET; no video sources.

Limitations: Absence of a FILM weights licence statement is from a README search only.

Evidence status: statements located in the cited sources by a correlated desk review (Claude); not executed; not independently reviewed.
