  "account": "Two ComfyUI graphs are included in this episode. Neither graph has been rendered or timed for this article, and the information provided should not be used for quality comparisons. The two graphs, MiniMax H3 FL2VA and MiniMax H3 Ref2VA, both contain keyframe timeline nodes and story beat nodes. The FL2VA graph focuses on a first frame and a last frame, allowing the motion between them to be tuned. The Ref2VA graph takes multiple references and arranges story beats on a keyframe timeline using 20 math/integer nodes. The number of steps, CFG, and sampler used in these graphs are not specified, as this article does not aim to provide a single tuple for reference. Open the graph in your own ComfyUI and examine the actual sampler widgets before assuming any specific settings. The keyframes offered by these graphs provide control over the motion and story beats, but they do not prove any inferences, render outputs, or speed comparisons. Additionally, the weights and input media used in these graphs are not included, so be sure to check the respective licenses before publishing any content created using these graphs. The source files can be found on Hugging Face, ModelScope, RunningHub, and Civitai, and the source video is available on YouTube.",
