Code licences are explicit: Real-ESRGAN BSD-3-Clause, RIFE and Practical-RIFE MIT, FILM Apache-2.0. Weight terms differ: Practical-RIFE states that the linked model files are under the same MIT licence as the project; the Real-ESRGAN, original RIFE and FILM READMEs and LICENSE files read make no separate statement about weights, which are distributed as release assets or Google Drive/Baidu links in pickle-capable or SavedModel formats. FILM additionally requires a third-party VGG .mat file whose terms were not read. No output-use terms were found in the documents read.

Curator qualifications: Code licences and the Practical-RIFE weights sentence verify verbatim. The silence on weights terms holds for the Real-ESRGAN README/model_zoo/FAQ, the RIFE README/LICENSE and the FILM README/LICENSE as read (search for licen/commercial/weights). Formats confirmed: .pth (Real-ESRGAN), .pkl (RIFE, Practical-RIFE flownet.pkl), TF SavedModel plus a VGG .mat (FILM). Curator addition (weights provenance): the Real-ESRGAN paper trains on DIV2K, Flickr2K and OutdoorSceneTraining, and FILM's README names Vimeo-90K for training. Dataset terms were not read, so weights rights remain unknown even where a code licence exists. Curator addition: the RIFE README states 'According to the open source license, we respect the commercial behavior of other developers' (L29), about third-party software built on RIFE. It is not a weights grant, but it is the only commercial-use wording in the RIFE files read. Copyright holders differ: RIFE (ECCV2022-RIFE) LICENSE is 'Megvii Inc.', Practical-RIFE LICENSE is 'hzwer' (2021). Practical-RIFE's 'same MIT license' statement therefore covers hzwer's Practical-RIFE models, not the Megvii paper models.
