Frequently Asked Questions

How does an AI caption generator work?+

It transcribes your video's audio with AI and overlays synced, styled captions automatically — no manual typing or timing. quso.ai supports 100+ languages.

How to generate captions from a video?+

To generate captions from a video, use an AI caption generator that automatically transcribes speech and syncs the text to the video timeline. Upload your video or paste a link, and the tool will create accurate video captions in seconds. You can then style, edit, and export them in formats like SRT, VTT, or as burned-in captions, ready for any platform.

How to save a video from a caption generator?+

Once your captions are created, most video caption makers let you download the video with captions burned in or export the subtitle file separately. To save the video from a caption generator, choose the “export with captions” or “download video” option. You can also download clean transcript files for later use or translation.

How do I add closed captions to a video for free?+

Closed captions are the accessibility standard format: timed, speaker-labelled text that works across platforms. Upload your video to quso.ai's AI caption generator, which automatically creates time-coded captions. Export as SRT (the standard closed caption format) and upload to YouTube Studio, TikTok, or LinkedIn or burn them directly into your video for platforms that don't support external caption files.

Is using an AI caption generator better than adding captions in Premiere Pro?+

For long-form editing workflows where you're already in Premiere Pro, the built-in caption tool works. For social video — anything being repurposed across TikTok, Instagram, YouTube Shorts, and LinkedIn — an AI caption generator like quso.ai is significantly faster: upload, auto-transcribe, style, and publish in one workflow without exporting/importing caption files between tools.

How to generate a caption transcript from a video?+

After uploading your video, the tool will transcribe the speech and allow you to export a clean text transcript or subtitle file.
