精选推荐
按视频质量、功能集、易用性和特定使用场景的性价比排名。
如何选择
这些工具服务于不同的需求。Runway 最适合生成式 AI 视频（文本转视频、图片转视频）和创意特效。Synthesia 和 HeyGen 使用 AI 虚拟人创建专业的口播视频——非常适合培训、营销和企业宣传。Descript 是一款以编辑器为核心的工具，增加了自动转录、填充词去除和眼神校正等 AI 功能。
预算差异显著。Descript 起价每月 24 美元，而 Synthesia 和 HeyGen 按视频时长收费，大批量制作时费用可能快速累积。
常见问题
AI 能从文本生成逼真的视频吗？ Runway 和类似工具可以根据文字提示生成短视频片段。质量已大幅提升，但最适合用于过渡画面、转场和创意内容，而非长篇叙事视频。
哪款 AI 工具最适合制作培训视频？ Synthesia 是培训和讲解视频领域的行业领导者。您可以在几分钟内使用 AI 虚拟人创建专业视频，无需摄像机或演员。
AI 视频编辑比传统编辑更简单吗？ 简单很多。Descript 让您通过编辑文本来编辑视频——删除一句话，对应的视频就会被删除。对于访谈和播客编辑来说，这种方式快得多。
