为什么信任本指南

I started making Synthesia videos months ago and have tested every feature here myself.

This tutorial comes from real projects, not vendor screenshots.

Synthesia is the 人工智能视频 generator most companies land on first.

但大多数用户只是浅尝辄止地体验了该平台的功能。

本指南将向您展示如何使用所有主要功能。

一步一步教你，附带截图和专业技巧。

Synthesia 入门指南

在创建任何内容之前，请完成此一次性设置。

大约需要三分钟。

Here is what my own first week looked like:

现在让我们一步一步来。

第一步：创建您的帐户

Go to the Synthesia website and click Get Started Free.

输入您的工作邮箱并创建密码。

✓ 检查点： 检查你的 收件箱 用于确认邮件。

步骤 2：打开 Web 应用程序

Synthesia runs in the browser, so there is nothing to install.

Log in and the dashboard loads with your recent projects and templates.

这就是它的样子：

✓ 检查点： You should see the main dashboard and a New Video button.

Step 3: Finish Onboarding

Answer the short setup questions about your team and use case.

Synthesia uses those answers to surface relevant templates on your home page.

Upload your logo and brand colours if you are on a paid plan.

如何使用 Synthesia AI 头像

AI化身 let you put a presenter on screen without hiring one.

以下是使用步骤。

Step 1: Open the Avatars Tab

Click Avatars in the left panel of the editor.

You get 150+ diverse AI avatars sorted by style, age and setting.

Step 2: Pick a Framing

Choose waist-up shots for intros and chest-up shots for detailed explanations.

Add gestures like head nods or raised eyebrows so the delivery feels less stiff.

这就是它的样子：

✓ 检查点： The avatar preview sits on your canvas at the framing you chose.

Step 3: Save It to the Scene

Drag your chosen avatar onto the canvas and lock the position.

Repeat for the rest of your scenes to keep one presenter throughout.

如何使用 Synthesia 文本转语音

文本转语音 turns your script into speech using AI 声音.

以下是使用步骤。

步骤 1：粘贴您的脚本

Drop your text into the script box under each scene.

Keep every scene focused on one idea so the AI reads it cleanly.

第二步：选择语音和语言

The speech engine covers 120+ languages and accents.

Match the accent to your audience, not to your own.

这就是它的样子：

✓ 检查点： 这 嗓音 name shows under each scene and captions appear in the preview.

Step 3: Add Pauses and Captions

Insert pause tags where you want breathing room in the narration.

Switch on closed captions so viewers can follow without sound.

如何使用 Synthesia 自定义模板

可自定义模板 save you from designing videos from scratch.

以下是使用步骤。

第一步：浏览图书馆

Open Templates from the dashboard and filter by use case.

There are 250+ pre-designed templates covering training, onboarding and marketing.

Step 2: Swap in Your Content

Replace the placeholder text, images and avatar with your own.

Keep a clear visual hierarchy in each scene so nothing feels crowded.

这就是它的样子：

✓ 检查点： Your own text and images now sit inside the template layout.

Step 3: Save It as Your Own

Save the edited layout as a reusable template for your team.

Custom assets and brand kits keep every future video on brand.

如何使用 Synthesia AI 视频编辑器

人工智能 视频编辑器 handles scenes, timing and animations without a timeline.

以下是使用步骤。

Step 1: Arrange Your Scenes

Each scene is a card, much like a slide in PowerPoint.

That familiar layout is why most people learn the editor in an afternoon.

Step 2: Add Media and Animations

Upload images or clips, then set simple entrance animations.

Adjust background music so the sound never fights the voice.

这就是它的样子：

✓ 检查点： Your media appears in the scene with the animation you picked.

Step 3: Preview Before You Generate

Hit play on the preview to check pacing and narration.

Fix anything odd, then click generate.

如何使用 Synthesia 协作和共享功能

协作与共享 keeps review cycles inside the platform.

以下是使用步骤。

Step 1: Open a Space

Synthesia Spaces group your team’s projects in one shared place.

Invite reviewers by email and set edit or comment access.

Step 2: Collect Timestamped Feedback

Reviewers leave comments pinned to the exact second.

You resolve each note as you fix it, so nothing gets lost.

这就是它的样子：

✓ 检查点： Comments appear in the side panel with a timestamp on each one.

Step 3: Share the Finished Video

Export an MP4 or generate share links for your audience.

Videos also push straight into most LMS apps.

如何使用 Synthesia AI 视频助手

人工智能视频 助手 builds a first draft from almost nothing.

以下是使用步骤。

Step 1: Give It a Starting Point

Enter a topic, a prompt or a public URL.

The assistant reads it and writes a scene-by-scene script.

Step 2: Review the Draft

Check the generated text against the FOCA framework: focus, outcome, content, action.

A strategic script drives roughly 80% of a video’s success.

这就是它的样子：

✓ 检查点： A full scene list appears with a script written under each scene.

Step 3: Edit and Approve

Rewrite anything that sounds generic, then approve the draft.

The assistant fills each scene with an avatar, visuals and voice.

如何使用 Synthesia AI 屏幕录制器

AI屏幕录制器 captures product walkthroughs inside Synthesia.

以下是使用步骤。

Step 1: Start a Recording

Click Record in the media panel and choose a tab or window.

No separate recording tool is needed.

Step 2: Trim the Capture

Cut dead air from the start and end of the clip.

Speed up slow sections so viewers stay with you.

这就是它的样子：

✓ 检查点： The trimmed clip sits in your media library, ready to drop into a scene.

Step 3: Add a Presenter

放置一个 人工智能化身 beside the recording to narrate what happens.

Match the voice to the rest of your video series.

如何使用 Synthesia 一键翻译

一键翻译 reaches global teams without re-recording anything.

以下是使用步骤。

Step 1: Open a Finished Video

Select every market you need in one pass.

这就是它的样子：

✓ 检查点： Each language appears as its own version inside your project list.

Step 3: Check Each Version

Watch a minute of each language before publishing.

Fix any term your glossary should have caught.

如何使用 Synthesia 交互式视频

互动视频 turn passive watching into active learning.

以下是使用步骤。

Step 1: Enable Interactivity

Open the video settings and switch on interactive elements.

This works on training videos and product tours alike.

Step 2: Add Hotspots and Quizzes

Drop clickable hotspots on key parts of the screen.

Add a short quiz to test whether the message landed.

这就是它的样子：

✓ 检查点： Hotspot and quiz markers show on the scene you edited.

Step 3: Set Branching Paths

Send viewers down different paths based on their answers.

New hires skip what they already know.

Synthesia 专业技巧和快捷键

After eight months of daily use, these are the tips I’d hand a new user.

键盘快捷键

大多数人错过的隐藏功能

• Synthesia Academy： free courses on localization and advanced production, with worked examples worth a deep dive.
• 品牌套装： lock fonts, colours and logo placement once so every video matches without manual checks.
• Pronunciation glossary: teach the AI how to say product names, then stop fixing the same word forever.

Synthesia 常见错误及避免方法

Mistake #1: Writing the script last

Mistake #2: Cramming every scene

Mistake #3: Skipping the preview

Synthesia故障排除

Problem: Video generation is stuck

原因： Long videos queue behind other jobs during busy hours.

使固定： Generation normally takes 3 to 20 minutes depending on length. Close the tab and wait for the email. Split anything over 10 minutes into shorter videos.

Problem: The avatar mispronounces your brand name

原因： The speech engine guesses unfamiliar words from spelling alone.

使固定： Add the word to your pronunciation glossary with a phonetic spelling. Regenerate that scene only, not the whole video.

Problem: An uploaded clip won’t play

原因： The file uses an unsupported codec or exceeds the upload limit.

使固定： Re-export as an MP4 with H.264 video and AAC sound, then upload again. Keep single files under the plan limit shown on the upload page.

📌 笔记： If none of these fix your issue, contact Synthesia support.

Synthesia是什么？

Synthesia is an AI video generator that creates studio-quality videos from text.

Think of it as a film crew that lives in a browser tab.

You write, it casts an avatar, records the voice and edits the result.

Companies create videos this way for onboarding, product updates and customer service.

Every video created here can be updated later without re-recording anything.

Synthesia is built on AI ethics and 安全. It is SOC 2 and GDPR compliant, and a Trust and Safety team reviews content with both human and AI moderation.

Non-consensual clones of celebrities or political figures are blocked, and explicit consent is required before any likeness is used.

The technology does not suit every job. High-impact 演示文稿 still need a real person on camera.
