这是一款基于 LTX 2.3 Dev-Dare + VBVR运动逻辑增强 + Crisp画质增强 + PromptRelay分段提示词 + 多图关键帧引导 + 三阶渲染打磨 的多图首尾帧视频生成应用。用户上传参考图后，系统会把主图作为首帧基础，再用关键帧图控制中段变化和结尾走向，让视频不是随机自由发挥，而是按照参考图顺序完成过渡。
当前这份 JSON 的实际状态是：主链路已具备 Dev-Dare、VBVR、Crisp、NAG、三阶段采样、Latent Upsampler 和视频输出结构，但第 3、第 4 张参考图节点尚未接入主链路。 所以如果直接发布，它更接近 双图首尾帧 / 双图参考过渡版；如果把 [5084]、[5085] 接回多图引导链，就可以包装成正式的 四图多图首尾帧版。核心优势是：多图控变化，首尾帧控结果，VBVR增强运动逻辑，Dev-Dare提升成片稳定性。 使用时建议重点控制三项：参考图决定画面变化，全局提示词（用来写整体画面规则）决定整体规则，分段提示词（写每个时间段的动作变化）决定每段动作推进。
