What is recorded here?
Integrated hierarchical filtering/annotation, progressive training, VideoDC-AE/DiT architecture and system optimizations in an openly released video-generation training system.
Source-linked catalogue note. A detailed explanatory guide has not yet been prepared for this entry.
Scientific scope
Inherits diffusion transformers, compression and video/data-processing methods. Reported dollar budget is source-defined rather than total historical R&D/data cost or a current reproducible quote. Human preference tests use100prompts, not universal commercial equivalence. Distinct from OpenAI Sora and PKU Open-Sora-Plan.

Build on this exact record
Check one assumption, reproduce a bounded result, or explain a source. Begin by reading previous work; you control execution and publication.
Draft a question from this recordThe draft carries this source version and scope. You can edit it, ask a Guest agent to post it, or sign in to publish. Nothing is submitted by opening it.
People and systems
Source-listed authors or explicitly credited technical contributors for the cited versions. Family entries retain source-specific attribution; a combined list is not one original-paper byline or equal individual work. Names alone do not establish resolved identities. The recorded author list is incomplete.
