Add Captions to Video in 3 Simple Steps with Our AI Subtitle Generator
1 Upload Your Video
Start by uploading the video you want to caption. Our AI Subtitle Generator works with any existing video that needs highly accurate subtitles, caption translation, or a formatting upgrade for social media.
2 Choose Your Subtitle and Editing Settings
Select your target language if you want to auto translate subtitles. You can also use Auto-reframe video to turn horizontal videos into a vertical (9:16) format, enable the AI video editor to add dynamic motion graphics, or turn on Add B-Roll to insert relevant AI-generated footage.
3 Generate and Export
Click generate and let our video caption generator do the heavy lifting. In just minutes, you will receive a video with 99.5% accurate, perfectly timed subtitles. You can burn the captions directly into your video or export them as a separate file.
01
99.5% Accurate AI Subtitles in 100+ Languages Without Manual Transcription
Upload your video and Revid generates accurate subtitles automatically in over 100 languages without any manual transcription work. The AI processes your audio, identifies every word spoken, and outputs correctly timed subtitle captions that sync precisely to the visuals. Accuracy reaches 99.5% across supported languages, meaning you spend almost no time correcting errors after the fact. The process takes a fraction of the time that manual transcription or editing-based captioning would require, even for long-form video content.
02
What the AI Subtitle Generator Adds to Your Videos
The subtitle generator produces fully timed captions that can be burned into the video or exported as a separate subtitle file. It handles speaker changes, background noise, accented speech, and rapid dialogue without losing accuracy. The output is formatted correctly for the aspect ratio of your video, whether you are working in vertical, square, or widescreen format. Captions are styled to be readable across platforms and can be adjusted for font size, position, and color before you export the final video.
03
Subtitles That Make Your Videos Accessible and Perform Better Everywhere
Most short-form video is watched without sound. Viewers scrolling TikTok, Instagram, and YouTube Shorts in public or at work rely entirely on subtitles to follow video content. Videos with accurate on-screen captions consistently outperform uncaptioned videos on every metric, including watch time, saves, and shares. Accessible content also reaches a larger audience by including viewers who are deaf or hard of hearing. Adding subtitles with Revid takes the same amount of time regardless of how long your video is.

FAQs
Frequently Asked Questions
What is the AI Subtitle Generator?
Revid's AI Subtitle Generator is an advanced editing tool that allows you to automatically add captions to video content. It uses cutting-edge artificial intelligence to transcribe spoken words and generate subtitles automatically with 99.5% accuracy in over 100 languages, saving you hours of manual transcription work.
How accurate is the auto subtitle generator?
Our auto subtitle generator is incredibly precise, boasting a 99.5% accuracy rate. The AI seamlessly handles background noise, various accents, and rapid speech, ensuring that when you add captions to video, every single word is perfectly synced to the audio track.
Can I auto translate subtitles into different languages?
Absolutely! Our AI video captioning tool supports over 100 languages. You can upload a video in one language and use the 'Translate captions to' feature to auto translate subtitles into your desired language. This makes it effortless to make your content accessible to a global audience.
What does the auto-reframe video feature do?
If you have a horizontal video (like a traditional YouTube video) and want to post it on TikTok or Instagram Reels, our AI can auto-reframe the video for you. It dynamically tracks the main subject and crops the video to a vertical 9:16 ratio, ensuring your newly captioned video looks perfect on mobile devices.
How does the AI video editor upgrade my captioned videos?
When you enable the AI video editor, our tool goes far beyond a simple video caption generator. It acts like a professional human editor: it cuts you out of the background, adds motion graphics behind you for key lines, and dynamically punches the camera in on important moments. The subtitles step aside to let the graphics shine, giving you a highly polished edit.
Can I add B-roll footage to my video using this tool?
Yes! Alongside generating subtitles automatically, you can choose to add B-roll. Our AI will search for or generate relevant media (like AI video clips, animated AI images, or stock videos) to visually illustrate your content. You can choose between split-screen or full-screen B-roll and even adjust how frequently the footage appears.
Why should I use a video caption generator for social media?
A vast majority of social media users watch short-form videos on mute. If you don't add captions to video content, you risk losing viewers instantly. An AI subtitle generator ensures your content is accessible, drastically improving watch time, engagement, and shareability across platforms like TikTok, YouTube Shorts, and Instagram.
How much does it cost to generate subtitles automatically?
The cost depends on the specific features you select. Basic subtitle generation uses a standard credit amount. Enabling advanced features like auto-reframe costs an additional 10 credits. The premium AI video editor feature uses 100 credits, plus 20 credits per 30 seconds of video. Your available credits depend entirely on your Revid AI subscription plan.
How long does it take to add captions to video?
Unlike manual transcription which can take hours of tedious typing, our AI Subtitle Generator processes your video in just a few minutes. Whether you are generating standard captions or using the auto translate subtitles feature, your ready-to-publish video will be available almost instantly.
Can I customize the look of the generated subtitles?
Yes, once the AI has generated the subtitles automatically, you can use our built-in editor to adjust the style, font, size, and color of your captions. This ensures the text perfectly matches your brand identity and remains highly readable on any screen size.
