Por que confiar neste guia?
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.
Passo a passo, com capturas de tela e dicas profissionais.
Tutorial de IA para legendas
This How to Use Captions AI tutorial walks through every feature in order.
It starts at your first upload and ends at export.
Legendas IA
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.
Primeiros passos com a IA de legendas
Antes de usar qualquer recurso, conclua esta configuração única.
Leva cerca de três minutos.
Here’s what the app looked like on my first project:
Agora vamos analisar cada etapa.

Insira seu e-mail e escolha uma senha.
✓ Ponto de verificação: A confirmation message lands in your caixa de entrada.

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.

Etapa 3: Conclua a configuração inicial
Pick your main language and your usual video format.
Then set your default caption style in settings.
✅ Concluído: Você está pronto para usar qualquer recurso abaixo.
How to Use Captions AI Creators
Criadores de IA lets you turn a script into a finished video using a stock presenter.
Veja como usá-lo passo a passo.
Step 1: Open the Creators tab
Clique Criadores de IA 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.
Eis como isso se parece:
✓ Ponto de verificação: The preview updates with your changes.
Etapa 3: Gerar e revisar
Clique Gerar and wait while the audio is processed.
Watch the draft, then trim any line that runs long.
✅ Resultado: A finished talking-head video with auto-captions burned in.
💡 Dica profissional: Write in short sentences. The AI handles pacing better, and the captions stay under 40 characters per line.
How to Use Captions AI Shorts
Curtas de IA lets you cut one long recording into several short clips ready to post.
Veja como usá-lo passo a passo.
Step 1: Upload your long video
Clique Upload and select a file from your computer.
A podcast, webinar, 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.
Eis como isso se parece:
✓ Ponto de verificação: The preview updates with your changes.
Step 3: Export the clips you want
Select your favourites, then export each one as a separate file.
✅ Resultado: Five to ten vertical clips sized for a YouTube channel or feed.
💡 Dica profissional: 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
Edição por IA lets you edit video by deleting words from the transcript.
Veja como usá-lo passo a passo.
Step 1: Open the transcript panel
Clique no Transcrição 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 imediatamente na transcrição.
Highlight a filler word, press delete, and the matching frames disappear.
Eis como isso se parece:
✓ Ponto de verificação: 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.
✅ Resultado: An edited cut with no gaps, silences, or stray “um” moments.
💡 Dica profissional: Run a search for “um” and “like” first. Removing those two words alone tightens most recordings by 10%.
How to Use Captions AI Twins
Gêmeos de IA lets you clone your own face and voice so you can post without filming.
Veja como usá-lo passo a passo.
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.
Eis como isso se parece:
✓ Ponto de verificação: 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.
✅ Resultado: A reusable digital twin that can create videos from text alone.
💡 Dica profissional: Record your training clip in the same location and lighting you normally film in. The twin blends into your other content.

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.
Eis como isso se parece:
✓ Ponto de verificação: The preview updates with your changes.
Step 3: Save it as a preset
Name the style and save it for your next project.
✅ Resultado: A saved caption preset you can apply to every future upload.
💡 Dica profissional: Keep captions to one or two lines. Anything longer forces viewers to read instead of watch.

Veja como usá-lo passo a passo.
Step 1: Open the avatar generator
Clique Criar, then choose the avatar option.

Removedor de ruído de fundo lets you remove hum, traffic, and room echo in one click.
Veja como usá-lo passo a passo.
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.

Veja como usá-lo passo a passo.
Step 1: Import the video
Drop your file into a new project and wait for the transcript.

Extra languages expand your reach to viewers who never speak English.
✅ Resultado: Captions in multiple languages, plus a subtitle file for your YouTube channel.
💡 Dica profissional: Export an SRT alongside the burned-in version. YouTube reads that file as closed captions and indexes the text.
Legendas: Dicas e Atalhos Profissionais de IA
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.
Atalhos de teclado
| Ação | Atalho |
|---|---|
| Play or pause the preview | Espaço |
| 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.
Características ocultas que a maioria das pessoas não percebe
- Espaços de trabalho: 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.
- Notas do orador: Paste your notes into the script field and the teleprompter reads them back.
Here are the benefits that show up fastest in real work:
Legendas com IA: Erros comuns a evitar
Mistake #1: Publishing captions without reading them
❌ Errado: Trusting the first pass and posting straight to your YouTube channel.
✅ Direita: Treat AI captions as a first draft. Fix names, jargon, and punctuation before you publish.
Mistake #2: Cramming too much text on screen
❌ Errado: Four lines of tiny text sitting over busy graphics.
✅ Direita: One or two lines, 37 to 40 characters each, in high-contrast colors.
Mistake #3: Ignoring the accessibility side
❌ Errado: Burning in captions only, so no subtitle file ever reaches viewers.
✅ Direita: Export an SRT too. Closed captions meet WCAG 2.1 and make videos accessible to more people.
Legendas IA - Solução de problemas
Problem: Captions are out of sync with the audio
Causa: The timeline shifted after you trimmed a clip.
Consertar: Open the transcript, select the caption, and drag its edge back onto the spoken line.
Problem: Names and technical words come out wrong
Causa: The AI misreads jargon, brand names, and strong accents.
Consertar: Edit the text directly, then add repeat offenders to your custom dictionary.
Problem: Export fails or the file will not upload
Causa: The project is too long for your plan, or the render was interrupted.
Consertar: Trim the video, lower the resolution, and export again on a stable connection.
📌 Observação: If none of these help, contact Captions AI support from the settings page.
O que é o Captions AI?
Legendas IA is an app that records, edits, and captions your video in one place.
Think of it as a studio, an editor, and a subtitle escritor sharing the same screen.
The team ships a new feature most months, so check the release notes.
Veja esta breve visão geral:
Inclui estas características principais:
- Criadores de IA: Script-to-video with licensed presenters and voices
- Vídeos curtos sobre IA: Automatic clip finding for long-form recordings
- Edição por IA: Transcript-based editing that removes filler words
- Gêmeos de IA: Face and voice cloning for text-to-video
- Personalização de vídeo: Caption styling, presets, and brand controls
- Gerador de Avatares com IA: Prompt-based custom avatars and voices
- Contato visual com IA: Gaze correction for scripted recordings
- Removedor de ruído de fundo: One-click noise and echo removal
- Legendas automáticas: 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.
