Generate Accurate AI Subtitles in 4 Simple Steps
1 Upload Your Video
Start by uploading the video you want to subtitle. Revid's AI subtitle generator analyzes the spoken audio in your file and prepares it for automatic transcription, caption timing, translation, and optional mobile reframing.
2 Choose Subtitle and Video Options
Keep the original language or enter a target language to translate captions automatically. You can also enable auto-reframe to convert your video into a mobile-friendly vertical format for TikTok, YouTube Shorts, and Instagram Reels.
3 Add Optional B-Roll or Visual Enhancements
If you want to make your subtitled video more engaging, enable AI B-roll. Revid can add relevant split-screen or full-screen visuals using AI video, moving AI images, motion graphics, stock footage, your own media, or static gameplay-style clips.
4 Generate, Edit, and Export
Click generate and let Revid create accurate, timed subtitles in minutes. Once your video is ready, use the built-in editor to adjust captions, styling, timing, layout, and visuals before exporting a finished video with subtitles or a subtitle 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 Revid AI Subtitle Generator?
The Revid AI Subtitle Generator is an online subtitle generator that automatically creates accurate subtitles for videos. Upload a video, and Revid uses AI to transcribe the audio, sync captions to the speaker timing, and generate readable subtitles for social media, YouTube, courses, ads, podcasts, interviews, tutorials, and more.
How do I generate subtitles for a video automatically?
To generate subtitles automatically, upload your video to the AI subtitle generator, choose whether you want to keep the original language or translate the captions, select optional settings like auto-reframe or B-roll, then click generate. Revid will process the audio and create timed subtitles that are ready to edit, download, or burn into the final video.
How accurate is the AI subtitle generator?
Revid's AI subtitle generator can reach up to 99.5% accuracy across supported languages. Accuracy depends on the quality of the audio, background noise, speaker clarity, accents, and how many people are speaking, but the tool is designed to dramatically reduce manual transcription and caption editing work.
Which languages does the subtitle generator support?
The AI subtitle generator supports subtitles in 100+ languages, making it useful for creators, businesses, educators, and marketing teams that publish videos for global audiences. You can generate captions in the original language or translate subtitles into another language to make your video easier to understand worldwide.
Can I translate subtitles into another language?
Yes. Revid works as both an AI subtitle generator and a subtitle translator. After uploading your video, enter the language you want in the "Translate captions to" field, such as English, Spanish, French, German, Italian, Portuguese, Hindi, or another supported language. Revid will generate translated subtitles for your video automatically.
Can I add subtitles to TikTok, YouTube Shorts, and Instagram Reels?
Absolutely. Revid's subtitle generator is built for short social videos, including TikTok videos, YouTube Shorts, and Instagram Reels. You can generate auto captions, reframe your video into a vertical mobile format, and export a ready-to-post video with subtitles that are easy to read on small screens.
What is the auto-reframe option?
Auto-reframe uses AI to adapt your video to a mobile-friendly aspect ratio, such as vertical 9:16. This is useful when you want to turn a horizontal video into a subtitled TikTok, YouTube Short, or Instagram Reel. The AI focuses the frame on the important parts of the video so your captions and subject remain clear. This option costs additional credits.
Can the AI subtitle generator add B-roll to my video?
Yes. Revid can add optional B-roll while generating subtitles. You can choose split-screen B-roll or full-screen B-roll, adjust the frequency, and select a media type such as AI video, moving AI images, motion graphics, stock videos, your own media, or static gameplay-style footage. This helps make captioned videos more dynamic and engaging.
Can I edit the subtitles after they are generated?
Yes. After the AI subtitle generator creates your captions, you can review and edit them inside Revid's built-in editor. You can correct words, adjust timing, change subtitle styling, move captions, update the layout, and fine-tune the final video before exporting.
Can I customize how the subtitles look?
Yes. Revid lets you customize subtitle appearance so your captions match your brand and platform. You can adjust subtitle style, position, size, and readability in the editor. Clear, well-styled subtitles are especially important for short-form videos because many viewers watch without sound.
Can I burn subtitles directly into the video?
Yes. You can export your final video with subtitles burned in, making the captions visible on any platform even if the viewer does not enable closed captions. Burned-in subtitles are ideal for TikTok, Instagram Reels, YouTube Shorts, LinkedIn videos, ads, and other social media videos.
Can I export subtitles as a separate subtitle file?
Revid is designed to help you generate timed subtitles that can be used with your video workflow. Depending on your export settings, you can create a subtitled video and use subtitle outputs for platforms that support separate caption files. This makes the subtitle generator useful for both social videos and longer-form publishing workflows.
What types of videos work best with the subtitle generator?
The AI subtitle generator works well for talking-head videos, podcasts, interviews, webinars, online courses, tutorials, product demos, marketing videos, YouTube videos, TikToks, Reels, and Shorts. For best results, upload a video with clear speech and minimal background noise.
Does the subtitle generator work with accents, fast speech, and background noise?
Yes, Revid's AI subtitle generator is built to handle real-world video audio, including accented speech, fast dialogue, speaker changes, and some background noise. Very noisy audio or overlapping speakers can reduce accuracy, but the generated subtitles can always be edited before export.
How long does it take to generate subtitles?
Most videos can be processed in minutes. The exact time depends on the length of your video, audio complexity, whether you translate subtitles, and whether you enable extra options like auto-reframe or AI B-roll. Revid is designed to save hours compared with manual subtitle creation.
How much does the AI subtitle generator cost?
The cost depends on your Revid plan, video length, and selected options. Basic subtitle generation uses credits, and optional features such as auto-reframe or B-roll may require additional credits. Before generation, Revid shows the estimated credit cost so you know what the subtitle generator will use.
Why should I add subtitles to my videos?
Adding subtitles makes your videos more accessible, easier to understand, and more effective on social platforms where many people watch without sound. Accurate video subtitles can improve watch time, retention, engagement, shares, and accessibility for viewers who are deaf, hard of hearing, or watching in a non-native language.
Can I use Revid's subtitle generator for commercial videos?
Yes. You can use videos created with Revid's AI subtitle generator for commercial use, including ads, client videos, product demos, educational content, brand videos, and monetized social media content. Make sure any uploaded media, music, or third-party content you use is properly licensed.
What is the difference between an AI subtitle generator and manual subtitling?
Manual subtitling requires listening to the video, typing every word, splitting captions, syncing timing, formatting subtitles, and checking translations. Revid's AI subtitle generator automates transcription, timing, translation, and formatting so you can create accurate subtitles in minutes instead of spending hours captioning videos manually.
