Kling 4.0 vs Seedance 2.5：2026年にどちらのAI動画生成ツールが優れている？

I don’t have reliable, public information on “Kling 4.0” or “Seedance 2.5” within my knowledge cutoff (Oct 2024). To provide an evidence-based comparison, please share official release notes, tech reports, API docs, pricing pages, or demo links. In the meantime, here’s a concise evaluation framework for the five dimensions you requested: - Creative control - Prompt expressivity and determinism (seed lock, style/shot/camera controls) - Reference conditioning (image/video refs, pose/Depth/ControlNet-like guides) - Editing tools (inpainting/outpainting, extend, keyframe control, multi-shot/storyboarding) - Character consistency, long-form coherence, physics constraints - Video quality - Max resolution/aspect ratios and fps - Motion naturalness, temporal consistency, subject/identity stability - Text rendering legibility, color/exposure/noise, artifact rates - Length limits and quality decay over duration; optional audio support - Benchmark evidence - Datasets and protocols (blind A/Bs, crowd or expert ratings) - Metrics appropriate for video (FVD, CLIPScore variants, temporal IQA) - Reproducibility (released prompts/seeds), third-party evaluations or leaderboards - API availability - Endpoints, auth, rate limits, async job model (job IDs, webhooks/callbacks) - Queues/priorities, SLAs, SDKs, client libs, streaming previews - Controls exposed via API (negative prompts, steps, guidance scales, safety filters) - Upload limits, storage/retention, data governance options - Production costs - Pricing units (per video/minute/frame/credit), resolution/fps/length tiers - Priority vs standard queue pricing, overage and throttling - Commercial licensing terms, usage rights, data retention opt-outs - Volume discounts, enterprise plans, on-prem or dedicated tenancy Share sources for Kling 4.0 and Seedance 2.5, and I’ll produce a side-by-side comparison across these criteria with citations.
