Reddit asks: why is open source still so far behind Seedance 2.5 for video?

A Reddit user argues that despite decent open models like MiniMax H3, Seedance 2.5 remains far ahead overall.

• The gap: Seedance wins on environment, lighting, realism, motion, consistency, prompt adherence, and supports videos up to 30 seconds.
• The pain: platform credits (e.g. Higgsfield) burn out fast during experimentation.
• The idea: even if the model gap can't be closed, could an open-source workflow — chaining models for individual shots, character consistency, transitions, and stitching into longer videos — get 70-80% of the way there via ComfyUI?
• The question: has anyone actually built such a workflow, or is the gap too big for orchestration to matter?
