为什么信任本指南
I’ve used Captions AI for eight months and tested every feature covered here.
This tutorial comes from real projects — not marketing copy or vendor screenshots.

Captions AI is one of the most popular AI video editing apps available today.
But most people only ever touch auto-captions and stop there.
Captions make videos more engaging for viewers watching with the sound off.
Creating a finished clip here takes minutes, not an afternoon.
This guide shows you how to use Captions AI end to end.
一步一步教你,附带截图和专业技巧。
字幕AI教程
This How to Use Captions AI tutorial walks through every feature in order.
It starts at your first upload and ends at export.

字幕人工智能
Record, edit, and caption video in one app. Captions AI writes your subtitles, cuts the filler words, and translates clips into multiple languages. Start free — no editing experience needed.
Captions AI 入门指南
在执行任何功能之前,请先完成此一次性设置。
大约需要三分钟。
Here’s what the app looked like on my first project:

现在让我们一步一步来。
第一步:创建您的帐户
Go to the Captions AI 网站 and click 报名.
请输入您的电子邮件地址并设置密码。
✓ 检查点: A confirmation message lands in your 收件箱.
步骤二:下载或访问应用程序
Captions AI runs on iOS, Android, and any desktop browser.
Install the mobile app if you film on your phone.
Log in, and the dashboard opens on the projects page.
✓ 检查点: You can see the 创造 button on screen.
步骤 3:完成初始设置
Pick your main language and your usual video format.
Then set your default caption style in settings.
✅ 完成: 您已准备好使用以下任何功能。
How to Use Captions AI Creators
AI 创造者 lets you turn a script into a finished video using a stock presenter.
以下是使用步骤。
Step 1: Open the Creators tab
点击 AI 创造者 on the left of the dashboard.
You will see a grid of licensed presenters on screen.
Step 2: Pick a creator and paste your script
Choose a face that fits your audience and your business.
Paste your script into the text box, then select a language.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
步骤 3:生成和审核
点击 产生 and wait while the audio is processed.
Watch the draft, then trim any line that runs long.
✅ 结果: A finished talking-head video with auto-captions burned in.
💡 专业提示: Write in short sentences. The AI handles pacing better, and the captions stay under 40 characters per line.
How to Use Captions AI Shorts
AI 短线 lets you cut one long recording into several short clips ready to post.
以下是使用步骤。
Step 1: Upload your long video
点击 Upload and select a file from your computer.
A podcast, 网络研讨会, or interview recording all work here.
Step 2: Let the AI find the hooks
The tool scans your audio and ranks the strongest moments.
Each suggested clip gets a score and a draft caption.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Export the clips you want
Select your favourites, then export each one as a separate file.
✅ 结果: Five to ten vertical clips sized for a YouTube channel or feed.
💡 专业提示: Check the first three seconds of every clip. A clean hook matters more than the rest of the edit.
How to Use Captions AI Editor
AI编辑 lets you edit video by deleting words from the transcript.
以下是使用步骤。
Step 1: Open the transcript panel
点击 文字稿 icon beside your project.
Every spoken word appears as editable text.
Step 2: Delete the words you do not want
Clicking a word selects it 即刻 在文字记录中。
Highlight a filler word, press delete, and the matching frames disappear.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Fix the wording
Correct any name or jargon the AI misheard.
The caption on screen updates as you type.
✅ 结果: An edited cut with no gaps, silences, or stray “um” moments.
💡 专业提示: Run a search for “um” and “like” first. Removing those two words alone tightens most recordings by 10%.
How to Use Captions AI Twins
AI双胞胎 lets you clone your own face and voice so you can post without filming.
以下是使用步骤。
Step 1: Record your training clip
Start by following the on-screen prompts and reading the sample text aloud.
Good lighting and clean audio decide how real the twin looks.
Step 2: Wait for training
Your clip is processed in the background, usually within a few hours.
You get a message when the twin is ready.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Type a script and generate
Paste new text and your twin says it in your own voice.
✅ 结果: A reusable digital twin that can create videos from text alone.
💡 专业提示: Record your training clip in the same location and lighting you normally film in. The twin blends into your other content.
How to Use Captions AI Video Customizer
视频定制 lets you control how every caption looks so your videos match your brand.
以下是使用步骤。
Step 1: Open caption settings
Click any caption on the preview to open the style panel.
All the styling elements sit in one place: font, size, and position.
Step 2: Set font, color, and position
Pick a font, then choose high-contrast colors so text stays readable.
Drag the caption box away from platform graphics.
Check how captions display on a phone before you move on.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Save it as a preset
Name the style and save it for your next project.
✅ 结果: A saved caption preset you can apply to every future upload.
💡 专业提示: Keep captions to one or two lines. Anything longer forces viewers to read instead of watch.
How to Use Captions AI Avatar Generator
人工智能化身 发电机 lets you build a presenter from a prompt and stay off camera.
以下是使用步骤。
Step 1: Open the avatar generator
点击 创造, then choose the avatar option.
Step 2: Describe the presenter you want
Write the age, style, and setting in one line of detail.
The AI returns several options in about a minute.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Attach a voice and script
Select a voice, paste your script, and generate the video.
✅ 结果: An original presenter you can reuse across an entire content series.
💡 专业提示: Generate three avatars and test each on one post. Engagement tells you which face your audience trusts.
How to Use Captions AI Eye Contact
AI眼神交流 lets you fix your gaze so you appear to face the camera.
以下是使用步骤。
Step 1: Upload the clip you read from notes
Any recording where your eyes drift off camera works.
Step 2: Turn on Eye Contact
Find the toggle in the effects panel and switch it on.
The preview shows the corrected gaze straight away.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Adjust the strength
Lower the slider if the effect looks too intense.
✅ 结果: A clip where you appear to hold eye contact with viewers throughout.
💡 专业提示: Keep your head still while reading. The effect corrects your eyes, not large head movement.
如何使用 Captions AI 背景噪音消除器
背景噪音消除器 lets you remove hum, traffic, and room echo in one click.
以下是使用步骤。
Step 1: Open the audio panel
Select your clip, then click the audio tab.
Step 2: Enable noise removal
Toggle it on and let the file process for a few seconds.
Try playing the before and after to compare.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Set the level
Dial it back if your voice starts to sound thin.
✅ 结果: Clean audio that also lifts caption accuracy on the next pass.
💡 专业提示: Clean the audio before generating captions. The AI mishears far fewer words when the room noise is gone.
如何使用AI自动字幕
自动字幕 lets you add captions to any video automatically and translate them into other languages.
以下是使用步骤。
Step 1: Import the video
Drop your file into a new project and wait for the transcript.
Adding captions this way takes seconds instead of an hour.
Step 2: Review the caption text
Read every line and fix spelling, names, and punctuation.
Check that each caption appears and leaves in time with the audio.
这就是它的样子:

✓ 检查点: The preview updates with your changes.
Step 3: Translate and export
Pick extra languages, then export burned-in captions or an SRT file.
Extra languages expand your reach to viewers who never speak English.
✅ 结果: Captions in multiple languages, plus a subtitle file for your YouTube channel.
💡 专业提示: Export an SRT alongside the burned-in version. YouTube reads that file as closed captions and indexes the text.
字幕AI专业技巧和快捷方式
After eight months with Captions AI, these are the habits that saved me the most time.
They help you work far more efficiently on every project.
键盘快捷键
| 行动 | 捷径 |
|---|---|
| Play or pause the preview | 空间 |
| Split the clip at the playhead | Cmd / Ctrl + B |
| Undo the last edit | Cmd / Ctrl + Z |
| Export the current project | Cmd / Ctrl + E |
These shortcuts alone cut my editing time roughly in half.
For example, splitting a clip by hand costs three separate clicks.
大多数人错过的隐藏功能
- 工作区: Keep client projects in separate workspaces so brand presets never mix.
- Keyword emphasis: Bold one or two words per caption to hold attention on small screens.
- Batch translate: Generate the same video in several languages before you publish anything.
- 演讲者备注: Paste your notes into the script field and the teleprompter reads them back.
Here are the benefits that show up fastest in real work:

避免字幕AI常见错误
Mistake #1: Publishing captions without reading them
❌ 错误: Trusting the first pass and posting straight to your YouTube channel.
✅ 右图: Treat AI captions as a first draft. Fix names, jargon, and punctuation before you publish.
Mistake #2: Cramming too much text on screen
❌ 错误: Four lines of tiny text sitting over busy graphics.
✅ 右图: One or two lines, 37 to 40 characters each, in high-contrast colors.
Mistake #3: Ignoring the accessibility side
❌ 错误: Burning in captions only, so no subtitle file ever reaches viewers.
✅ 右图: Export an SRT too. Closed captions meet WCAG 2.1 and make videos accessible to more people.
字幕AI故障排除
Problem: Captions are out of sync with the audio
原因: The timeline shifted after you trimmed a clip.
使固定: Open the transcript, select the caption, and drag its edge back onto the spoken line.
Problem: Names and technical words come out wrong
原因: The AI misreads jargon, brand names, and strong accents.
使固定: Edit the text directly, then add repeat offenders to your custom dictionary.
Problem: Export fails or the file will not upload
原因: The project is too long for your plan, or the render was interrupted.
使固定: Trim the video, lower the resolution, and export again on a stable connection.
📌 笔记: If none of these help, contact Captions AI support from the settings page.
什么是Captions AI?
字幕人工智能 is an app that records, edits, and captions your video in one place.
Think of it as a studio, an editor, and a subtitle 作家 sharing the same screen.
The team ships a new feature most months, so check the release notes.
观看这段快速概览:
它包含以下主要特点:
- AI 创造者: Script-to-video with licensed presenters and voices
- AI 短线: Automatic clip finding for long-form recordings
- AI编辑: Transcript-based editing that removes filler words
- AI双胞胎: Face and voice cloning for text-to-video
- 视频定制: Caption styling, presets, and brand controls
- AI虚拟形象生成器: Prompt-based custom avatars and voices
- AI眼神交流: Gaze correction for scripted recordings
- 背景噪音消除器: One-click noise and echo removal
- 自动字幕: Automatic captions, translation, and SRT export
AI captioning works in two passes.
First the app transcribes your audio into text, then it times each caption to the words.
One note on scope: this handles video, not still photos.
Image captioning in AI is a separate job, so use an image tool for that.
