Sidecar: Training-Free Semantic Reuse for Character-Consistent Free-form Visual Storytelling

Read the original on arXiv Computer Vision →

Sidecar is a plug‑and‑play semantic augmentation module that preserves entity‑level information from a character’s initial description and injects missing semantics into later prompt embeddings, enabling training‑free character consistency in free‑form visual storytelling. It works with existing diffusion models without architectural changes and incurs negligible computational overhead. Experiments on FreeStoryBench demonstrate consistent improvements in prompt‑image alignment and character consistency across SDXL and FLUX baselines.

Not Just a Subject: Capturing Adaptive Scene-Specific Variance for Visual Storytelling

EOS-Story is a training‑free framework that improves visual storytelling by balancing identity consistency with scene‑specific adaptation. It separates narrative prompts into identity and scene sub‑prompts and introduces Cross‑Contextual Bridging to inject appearance cues into the scene embedding. In the vision space, Adaptive Identity Preservation aligns identity features to the scene scale and uses Identity‑Aware Self‑Attention to avoid structural artifacts, achieving competitive results on the extended Consistory+ benchmark.

Weave Forcing: Compositional Memory Routing for Interactive Long Video Generation

Weave Forcing is a training‑free framework that enhances interactive long video generation by enabling compositional memory routing. It uses an LLM to split user prompts into character and background slots, then applies masked memory weaving with semantic masks to selectively retrieve relevant historical references. The method also introduces coverage‑adaptive RoPE to adjust temporal offsets based on reference coverage, reducing visual artifacts and improving cross‑shot consistency while preserving visual quality and text alignment.
