FAQs About AI Subtitle Generator

What is a caption generator or subtitle generator?

A caption generator or subtitle generator is a tool that automates adding subtitles to a video with AI technology, converting audio to subtitles, or on-screen text, for better accessibility, engagement, and localization. It should be noted that it differs from tools like an Instagram caption generator, which are designed primarily for creating text for images rather than syncing subtitles with video content.

Can I use it to generate YouTube subtitles?

Yes, you can. The tool supports YouTube closed captioning and can extract subtitles from YouTube videos unsubtitled originally, allowing you to edit, translate, or reuse them for improved accessibility and reach. It also helps creators save time by automatically generating accurate captions for long or complex videos.

Can this tool support for subtitles download separately?

Yes. The tool also works as an SRT file generator, allowing you to download subtitles separately in SRT format for editing, translation, or integration. This makes it easy to manage subtitles independently, reuse them across multiple videos, or share them with collaborators before reuploading the subtitled videos to other platforms.

Closed captions vs Subtitles: what is the difference?

In brief, closed captions (CC) display spoken dialogue and sound cues for accessibility, while subtitles mainly show translated or original text for viewers. Professional closed captioning services ensure accurate timing, formatting, and synchronization, making videos fully accessible to hearing-impaired audiences and improving comprehension for all viewers.

Can I generate translated subtitles for movies directly with this feature?

Sorry, this video subtitle generator only provides captions generation in the original language. For translated subtitles or localization, you can use our AI Video Translator feature, which converts audio and generates accurate subtitles in multiple languages, making it easy to reach international audiences and streamline the localization process.

How to add captions to video or audio with video caption APP on my mobile phone?

Currently, we don't have a mobile app, but you can still create subtitles on your phone browser. Simply use the web platform for adding captions to videos, allowing you to record, edit, and generate captions directly from your mobile device without installing any additional software.

Can I adjust the font with this voice-to-text converter?

Currently, this caption creator doesn't support font changes, but you can adjust subtitle placement (e.g., top or bottom of the screen) and customize the line-wrapping style for longer captions. This ensures readability and proper formatting, making subtitles clear and well-organized for any video content.

Does GStory provide a free caption generator?

Absolutely yes! You can add subtitles to video online free by using GStory's free credits. By registering or inviting friends, you earn points that can be redeemed to generate subtitles at no cost, making it easy for creators to try out the tool and produce accurate captions for multiple videos.
