Attributions

html-video is licensed under Apache-2.0. Some of its bundled video templates are derived from open-source design skills under permissive licenses. This file records every upstream we built on, its real copyright holder, and its license, as required by the upstream licenses and by RFC-07 (our PPT-skill → template conversion standard).

What "derived" means here: we transformed static presentation/slide designs into animated hyperframes video templates — rebuilt as original CSS/SVG keyframe timelines, re-coloured/re-typed where noted, with our own sample data. No upstream source code is copied verbatim. The upstream licenses (MIT) permit commercial use and derivative works; we attribute them regardless.

Many of these design styles are themselves homages to real-world design studios. Where a template is inspired by a specific studio, we record that as the L1 origin in the template's provenance block — as a factual statement of inspiration, never as a claim of affiliation or endorsement. Studio names are not used as template names.
