How to Add Captions to a Video
Voicap turns spoken video into timed, editable subtitles and burns the finished captions into a publish-ready MP4. This guide explains the complete workflow inside your signed-in studio.
Sign in to Voicap
Open your account to access the subtitle studio, saved projects, processing quota, and exported videos.
Upload your video
Start a subtitle project and upload an MP4 or MOV talking-head video from your device.
Choose the spoken language
Tell Voicap which language is spoken so automatic transcription starts with the right language context.
Generate timed subtitles
Voicap transcribes the speech and creates caption lines aligned to the video timeline.
Review the text and timing
Play the video, correct names or punctuation, adjust line breaks, and refine when each subtitle appears.
Style the subtitles
Choose a preset or customize the font, size, color, outline, position, and word-level emphasis.
Add translated caption tracks
When you need localized versions, create target-language tracks and review every translated line before export.
Hard-burn and export
Choose source, translated, or bilingual captions, then render a downloadable MP4 with the subtitles permanently embedded.
Soft subtitles or hard-burned subtitles?
Use a separate subtitle track when viewers need to toggle captions. Use hard-burned subtitles when the styling must remain visible and consistent across short-form platforms.
Frequently asked questions
Do I need to install software?
No. Voicap runs in your web browser, while subtitle processing and export happen through your signed-in account.
Can I edit automatically generated subtitles?
Yes. Review and change the caption text, timing, line breaks, and visual style before exporting.
What is the difference between soft and hard subtitles?
Soft subtitles are separate tracks that viewers or platforms can toggle. Hard subtitles are rendered into the video pixels and stay visible everywhere.
Can I add subtitles in another language?
Yes. You can create translated caption tracks, review them, and export source, translated, or bilingual versions according to your plan.
Does subtitle translation change the original audio?
No. The subtitle workflow keeps the original audio and localizes the on-screen text.
