Video Subtitles FAQ

How do I add subtitles to a video?

Simply upload your video file (MP4, MOV, AVI, and more) to HappyScribe. Our AI subtitle generator will automatically transcribe the audio and create accurate, time-coded subtitles. You can then edit them, export them as SRT file or VTT file, or burn them into your video directly.

Is the subtitle generator free to use?

You can try HappyScribe’s subtitle generator for free with limited minutes to test the platform. After that, you can choose from flexible pricing based on the length of your video or switch to a subscription plan that suits your needs.

Can I edit subtitles online after they’re generated?

Yes! Once your subtitles are generated, you’ll be able to use our online subtitle editor to correct timing, edit text, add speaker names, and format the style. It’s intuitive and doesn’t require any special video editing skills.

What if my subtitles are out of sync with the video?

No problem. In the subtitle editor, you can manually adjust the timing of each subtitle or use the auto-sync tool to realign them with the video. This is especially useful if you’ve uploaded your own SRT or VTT file.

Can I translate the subtitles automatically?

Absolutely. HappyScribe allows you to translate subtitles into over 120+ languages with just a few clicks. Whether you’re creating content for a global audience or need multilingual subtitles for accessibility, our platform makes it easy.

What’s the difference between subtitles and captions?

Subtitles reflect the spoken words in a video, usually for viewers who can hear but may not understand the language. Captions include additional information like [music playing] or [laughter] and are intended for deaf or hard-of-hearing viewers. HappyScribe supports both.

What are hardcoded subtitles and how do I export them?

Hardcoded (or burned-in) subtitles are permanently embedded into your video. With HappyScribe, you can choose to burn subtitles into your video directly or download them separately as subtitle files. Perfect for platforms that don’t support external files.

Subtitles for your video with 99% Accuracy

Adding subtitles to your videos shouldn’t be complicated or time-consuming. Whether you’re a content creator, educator, marketer, or team working across borders, HappyScribe makes it simple to subtitle videos with speed, precision, and ease.

Our online subtitle generator uses advanced speech recognition to automatically create subtitles from your video in seconds. Just upload your video file—MP4, MOV, AVI, or any other common format—and we’ll generate accurate, time-stamped subtitles instantly. Prefer to work with your own caption file? You can also upload subtitles in formats like SRT, VTT, or TXT.

Edit and customize your subtitles using our interactive editor. You can tweak timing, adjust formatting, and even add speaker names. When you’re ready, choose to export your subtitles as standalone files or burn subtitles directly into the video to create a hardcoded version ready to publish.

Want to reach a global audience? With support for 120+ languages, HappyScribe also lets you translate subtitles with just a few clicks, making your content accessible worldwide—even without sound.

From boosting accessibility to improving engagement and SEO, HappyScribe is your all-in-one solution to add subtitles to video online—accurately, quickly, and securely.

  • Quick, efficient, and very nice results
    Quick, efficient, and very nice results. Very reasonable pricing. I used it on some rather busy videos to produce subtitles, which I then translated. I will be using it more in the future.
