Pourquoi faire confiance à ce guide ?
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.
Étape par étape, avec captures d'écran et conseils de pro.
Tutoriel sur l'IA pour les sous-titres
This How to Use Captions AI tutorial walks through every feature in order.
It starts at your first upload and ends at export.
IA de sous-titrage
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.
Premiers pas avec l'IA de légende
Avant toute fonctionnalité, veuillez terminer cette configuration unique.
Cela prend environ trois minutes.
Here’s what the app looked like on my first project:
Passons maintenant en revue chaque étape.
Étape 1 : Créez votre compte
Go to the Captions AI site web and click S'inscrire.
Saisissez votre adresse e-mail et choisissez un mot de passe.
✓ Point de contrôle: A confirmation message lands in your boîte de réception.
Étape 2 : Téléchargez ou accédez à l’application
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.
✓ Point de contrôle: You can see the Créer button on screen.
Étape 3 : Terminer la configuration initiale
Pick your main language and your usual video format.
Then set your default caption style in settings.
✅ Terminé : Vous êtes prêt à utiliser n'importe quelle fonctionnalité ci-dessous.
How to Use Captions AI Creators
Créateurs d'IA lets you turn a script into a finished video using a stock presenter.
Voici comment l'utiliser étape par étape.
Step 1: Open the Creators tab
Cliquez Créateurs d'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.
Voici à quoi cela ressemble :
✓ Point de contrôle: The preview updates with your changes.
Étape 3 : Générer et examiner
Cliquez Générer and wait while the audio is processed.
Watch the draft, then trim any line that runs long.
✅ Résultat : A finished talking-head video with auto-captions burned in.
💡 Conseil de pro : Write in short sentences. The AI handles pacing better, and the captions stay under 40 characters per line.
How to Use Captions AI Shorts
Courts métrages IA lets you cut one long recording into several short clips ready to post.
Voici comment l'utiliser étape par étape.
Step 1: Upload your long video
Cliquez Upload and select a file from your computer.
A podcast, webinaire, 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.
Voici à quoi cela ressemble :
✓ Point de contrôle: The preview updates with your changes.
Step 3: Export the clips you want
Select your favourites, then export each one as a separate file.
✅ Résultat : Five to ten vertical clips sized for a YouTube channel or feed.
💡 Conseil de pro : 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
Édition IA lets you edit video by deleting words from the transcript.
Voici comment l'utiliser étape par étape.
Step 1: Open the transcript panel
Cliquez sur Transcription 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 immédiatement dans la transcription.
Highlight a filler word, press delete, and the matching frames disappear.
Voici à quoi cela ressemble :
✓ Point de contrôle: 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.
✅ Résultat : An edited cut with no gaps, silences, or stray “um” moments.
💡 Conseil de pro : Run a search for “um” and “like” first. Removing those two words alone tightens most recordings by 10%.
How to Use Captions AI Twins
Jumeaux IA lets you clone your own face and voice so you can post without filming.
Voici comment l'utiliser étape par étape.
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.
Voici à quoi cela ressemble :
✓ Point de contrôle: 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.
✅ Résultat : A reusable digital twin that can create videos from text alone.
💡 Conseil de pro : 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
Personnalisation vidéo lets you control how every caption looks so your videos match your brand.
Voici comment l'utiliser étape par étape.
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.
Voici à quoi cela ressemble :
✓ Point de contrôle: The preview updates with your changes.
Step 3: Save it as a preset
Name the style and save it for your next project.
✅ Résultat : A saved caption preset you can apply to every future upload.
💡 Conseil de pro : Keep captions to one or two lines. Anything longer forces viewers to read instead of watch.
How to Use Captions AI Avatar Generator
Avatar IA Générateur lets you build a presenter from a prompt and stay off camera.
Voici comment l'utiliser étape par étape.
Step 1: Open the avatar generator
Cliquez Créer, 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.
Voici à quoi cela ressemble :
✓ Point de contrôle: The preview updates with your changes.
Step 3: Attach a voice and script
Select a voice, paste your script, and generate the video.
✅ Résultat : An original presenter you can reuse across an entire content series.
💡 Conseil de pro : Generate three avatars and test each on one post. Engagement tells you which face your audience trusts.
How to Use Captions AI Eye Contact
Contact visuel IA lets you fix your gaze so you appear to face the camera.
Voici comment l'utiliser étape par étape.
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.
Voici à quoi cela ressemble :
✓ Point de contrôle: The preview updates with your changes.
Step 3: Adjust the strength
Lower the slider if the effect looks too intense.
✅ Résultat : A clip where you appear to hold eye contact with viewers throughout.
💡 Conseil de pro : Keep your head still while reading. The effect corrects your eyes, not large head movement.
Comment utiliser l'outil de suppression du bruit de fond par IA pour les sous-titres
Suppression du bruit de fond lets you remove hum, traffic, and room echo in one click.
Voici comment l'utiliser étape par étape.
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.
Voici à quoi cela ressemble :
✓ Point de contrôle: The preview updates with your changes.
Step 3: Set the level
Dial it back if your voice starts to sound thin.
✅ Résultat : Clean audio that also lifts caption accuracy on the next pass.
💡 Conseil de pro : Clean the audio before generating captions. The AI mishears far fewer words when the room noise is gone.
Comment utiliser les sous-titres automatiques de Captions AI
Sous-titres automatiques lets you add captions to any video automatically and translate them into other languages.
Voici comment l'utiliser étape par étape.
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.
Voici à quoi cela ressemble :
✓ Point de contrôle: 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.
✅ Résultat : Captions in multiple languages, plus a subtitle file for your YouTube channel.
💡 Conseil de pro : Export an SRT alongside the burned-in version. YouTube reads that file as closed captions and indexes the text.
Astuces et raccourcis pour les pros de l'IA de sous-titrage
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.
Raccourcis clavier
| Action | Raccourci |
|---|---|
| Play or pause the preview | Espace |
| 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.
Fonctionnalités cachées que la plupart des gens ignorent
- Espaces de travail : 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.
- Notes de l'orateur : Paste your notes into the script field and the teleprompter reads them back.
Here are the benefits that show up fastest in real work:
Erreurs courantes à éviter avec l'IA de sous-titrage
Mistake #1: Publishing captions without reading them
❌ Faux : Trusting the first pass and posting straight to your YouTube channel.
✅ À droite : Treat AI captions as a first draft. Fix names, jargon, and punctuation before you publish.
Mistake #2: Cramming too much text on screen
❌ Faux : Four lines of tiny text sitting over busy graphics.
✅ À droite : One or two lines, 37 to 40 characters each, in high-contrast colors.
Mistake #3: Ignoring the accessibility side
❌ Faux : Burning in captions only, so no subtitle file ever reaches viewers.
✅ À droite : Export an SRT too. Closed captions meet WCAG 2.1 and make videos accessible to more people.
Dépannage de l'IA des sous-titres
Problem: Captions are out of sync with the audio
Cause: The timeline shifted after you trimmed a clip.
Réparer: Open the transcript, select the caption, and drag its edge back onto the spoken line.
Problem: Names and technical words come out wrong
Cause: The AI misreads jargon, brand names, and strong accents.
Réparer: Edit the text directly, then add repeat offenders to your custom dictionary.
Problem: Export fails or the file will not upload
Cause: The project is too long for your plan, or the render was interrupted.
Réparer: Trim the video, lower the resolution, and export again on a stable connection.
📌 Note: If none of these help, contact Captions AI support from the settings page.
Qu'est-ce que Captions AI ?
IA de sous-titrage is an app that records, edits, and captions your video in one place.
Think of it as a studio, an editor, and a subtitle écrivain sharing the same screen.
The team ships a new feature most months, so check the release notes.
Regardez ce bref aperçu :
Il comprend les fonctionnalités clés suivantes :
- Créateurs d'IA : Script-to-video with licensed presenters and voices
- Courts métrages IA : Automatic clip finding for long-form recordings
- Édition IA : Transcript-based editing that removes filler words
- Jumeaux IA : Face and voice cloning for text-to-video
- Personnalisation vidéo : Caption styling, presets, and brand controls
- Générateur d'avatars IA : Prompt-based custom avatars and voices
- Contact visuel IA : Gaze correction for scripted recordings
- Suppresseur de bruit de fond : One-click noise and echo removal
- Sous-titres automatiques : 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.
