H3 Infinite Continuation Suite v1.4: FL2VA Workflows with Native Masked AV
HerrgottMargott · reddit · 2026-08-23
H3 Infinite Continuation Suite v1.4 is released, optimizing long-form video generation for the MiniMax H3 model. Leveraging ComfyUI's native Masked AV support, it uses a First/Last Frame (FL2VA) mechanism for high-quality continuation instead of simple infinite generation.
Core Principles:
- FL2VA Loop: The logic revolves around a "First Frame → Generation → Last Frame" loop, using repeated last frames as visual anchors to minimize context drift and quality degradation over long chains.
- Auto Handover: To prevent H3 from freezing or becoming unstable before reaching the supplied Last Frame, the algorithm analyzes the previous clip to find a safe handover point for cutting and latent transfer, avoiding bad endings.
- Independent Audio Tail: Supports continuing audio beyond the visual cut to handle cases where speech outlasts the video.
New Features:
- Native Masked Video + Audio Latent Continuation
- Support for up to 9 Qwen reference images
- Individual clip regeneration
- Memory-bounded stitching for long chains
