That said, it’s not entirely free-to-use, as users will be required to have enough credits on their account to access the startup’s most advanced Gen-3 Alpha video generation model.该工具从10月22日开始面向用户推出，拥有Runway账号的人都可以获取。不过，该工具并非完全免费，账号中有足够的积分的用户才能访问该初创公司最先进的Gen-3 Alpha视频生成模型。In the filmmaking industry, facial animation is an intricate and expensive task that involves using sophisticated motion capture technologies, manual face rigging techniques and lots of heavy editing behind-the-scenes. Using the tool, creators will be able to animate their video characters in almost any way they can imagine, without needing to use pricey motion capture equipment.在电影制作行业中，面部动画是一项复杂且昂贵的任务，涉及使用先进的动作捕捉技术、手动面部绑定技术和大量的幕后剪辑。使用Act-One，创作者能够以几乎任何他们能想到的方式为自己的视频角色制作动画，而无需使用昂贵的动作捕捉设备。*译注*1. 动作捕捉技术：例如，在动捕服上放置标记点。2. 手动面部绑定技术：动画师手动在面部模型上设置关键点和控制器，通过这些控制器逐帧调整面部表情，使其更加自然。Act-One can be utilized by a range of creative professionals, including animators, video game developers and indie filmmakers, enabling them to generate more unique characters whose personality and actions can be reflected with their emotions and expressions. They’ll be able to create much more realistic, cinema-like video characters and capture them at any camera angle or focal length, Runway said, unlocking the potential for much richer, more detailed storytelling and artistic expression.Act-One可供大批创意专业人士使用，包括动画师、游戏开发者和独立电影人，帮助他们生成更多独一无二的角色，这些角色的性格和行为可以通过情绪和表情得以展现。Runway表示，创意专业人士将会创造出更加逼真、更具电影感的视频角色，并可以在任意拍摄角度或镜头焦距下捕捉这些角色，从而解锁更丰富、更细腻的叙事与艺术表达的可能性。Runway added that Act-One comes with a number of built-in safeguards that will prevent misuse, including guardrails that will prevent efforts to generate content featuring public figures without their express authorization. It’s also integrated with tools to verify voice usage rights, the company said. In addition, Runway will perform continuous monitoring of the tool to ensure it is used in a responsible way by creators.Runway补充说，Act-One配备了一系列防止滥用的内置保障措施，包括一项防护机制，用于防止未经公众人物授权而生成以公众人物为特色的内容。Runway还表示，Act-one还集成了验证语音使用权的工具。此外，Runway将对Act-one进行持续监控，以确保创作者可以负责地使用该工具。
