Synthesia 发布 Syren：一句提示词生成视频与动态图形

Summary

Syren is Synthesia’s new AI video creation tool. Describe your video or share a document, and it builds motion graphics, avatars and voiceover.

• Today we're launching Syren in beta, a new way to create video from a prompt, a preset, or a branded document, video or image you already have
• Describe the video you want, or share the material you have, and Syren builds a finished video with motion graphics, animation, avatars, voiceover, music and b-roll, then refines it with you in chat
• Syren is Synthesia’s video creation tool for fast, creative enterprise video: launch videos, explainers and marketing content

AI agents are changing how work gets done. Instead of operating software step by step, people describe what they want and the agent does the work. Syren brings that to video. A launch video, a feature explainer or a marketing clip can start with a sentence: describe it, and Syren’s agent builds it live, then refines it with you through chat.

Syren runs on a video rendering engine Synthesia built in-house. That engine has been quietly powering motion graphics inside Synthesia since June. Syren is what we built on top of it: a creation experience where the AI agent doesn’t assist the editor, it is the editor.

Describe it, and Syren builds it

Start with a prompt or a preset. Add branded documents, images, videos, PowerPoints or YouTube links. Syren’s agent writes the whole video as code and the rendering engine plays it back live, so you watch the video take shape as it’s built. 

Syren includes a new editor with playback, a transcript view and chat-based editing, so you ask for a change instead of starting over.

Videos render in your browser inside Synthesia, with nothing to install, and can run up to three minutes, horizontal or vertical. You can steer the look by giving Syren your brand assets, a video whose style you want it to match, or a description of your brand.

Where Syren fits

Syren joins Roleplays, Surveys and the Synthesia editor as part of the Synthesia platform. Syren is built for speed and creative output. The editor remains the place for content that has to be exact and repeatable: learning content, compliance training, onboarding and internal communications.

What’s coming

Syren will soon learn a company’s brand from its existing videos, capturing graphics and motion style, pacing and the rhythm of its edits, so every video follows it automatically.

How to access Syren today

Syren launches today in beta for self-serve, free and all Enterprise customers, through a Syren button in the left-hand navigation of Synthesia.
