图像 / 视频 / 音频工具怎么选How to choose image, video and audio tools

图像、视频、音频工具的第一道筛子不是「效果好不好」，而是商用许可。 第二道是输入输出与编辑链，第三道是本地还是云端，最后才是价格。 本篇不排名、不报价格；许可原文与定价以官方页为准。

The first screen for image, video and audio tools is not "does it look good" but commercial licensing. The second is input/output and edit chains, the third is local vs cloud, and price comes last. This guide ranks nothing and quotes no prices; licence text and pricing follow the official pages.

| What to check | Why | Where | |---|---|---| | Commercial use of output | Free tiers often allow personal use only | official terms / pricing pages | | Training-data provenance | Some tools claim "commercially safe" based on licensed training data | official trust/legal pages | | Voice cloning and likeness | You need consent from the person cloned; platforms may require extra verification | official voice/face cloning terms | | Font and asset embedding | Font licences differ by embedding method; game/App embedding often needs a commercial licence | the font's official licence page |

• 输入：文生图、图生图、视频生视频、音频驱动口型，支持的输入类型决定工作流。
• 输出：分辨率、时长、水印、文件格式；能否导出无损或分层文件。
• 编辑链：能否局部重绘、扩图、替换主体、保持角色一致性；是否支持时间线或分镜。
• 批量与 API：要量产就看是否有官方 API、并发限制与商用条款，而不是只看网页版。

- Input: text-to-image, image-to-image, video-to-video, audio-driven lip sync; supported inputs determine the workflow. - Output: resolution, duration, watermark, file format; whether lossless or layered files can be exported. - Edit chain: inpainting, outpainting, subject replacement, character consistency; timeline or storyboard support. - Batch and API: for volume, check official APIs, concurrency limits and commercial terms, not just the web UI.

• 本地：模型权重与算力在你手里，适合隐私敏感、离线、长期高频；代价是显卡、部署与运维。
• 云端：开箱即用、模型更新快；代价是按量计费、数据出境与网络依赖。
• 混合：本地跑批量、云端做难例，是常见折中；要确认两端产出的格式与许可一致。

- Local: weights and compute stay with you — good for privacy, offline use and high long-term volume; the cost is GPUs, deployment and operations. - Cloud: ready to use and fast to update; the cost is metered billing, cross-border data and network dependency. - Hybrid: local for batches, cloud for hard cases — a common compromise; confirm both sides produce compatible formats and licences.

• 中文提示词的遵循度、中文文字渲染、中文语音的自然度，都要用你自己的样本测。
• 国内直连、备案与数据出境是独立约束；海外工具在大陆可能直连超时。
• 商用发布还要看平台对 AI 生成内容的标识要求（水印、内容凭证）。

- Test Chinese prompt adherence, Chinese text rendering and Chinese speech naturalness with your own samples. - Mainland reachability, filing and cross-border data are separate constraints; overseas tools may time out from the mainland. - Commercial publishing also depends on AI-content labelling rules (watermarks, content credentials).

• 把「免费可用」当成「可商用」：免费档通常不含商用授权。
• 把「生成效果好」当成「工作流可用」：不能局部修改或保持一致性，产量一大会返工。
• 把「有网页版」当成「有 API」：量产要看官方 API 与并发限制。
• 忽略字体与音乐：生成画面之外的字体、配乐、音效仍受各自许可约束。

- Mistaking "free to use" for "licensed for commercial use": free tiers usually exclude commercial rights. - Mistaking "good output" for "usable workflow": without local editing or consistency, volume creates rework. - Mistaking "has a web UI" for "has an API": volume depends on official APIs and concurrency limits. - Ignoring fonts and music: fonts, scores and sound effects outside the generated image keep their own licences.
