Auto Subtitles: Add Animated Captions to Video Automatically
Transcribe your video and burn in karaoke-style animated captions for 3 credits, with control over language, font color, highlight color, and position.


How Auto Subtitles works
- 01
Upload your video
Add the clip you want captioned. Viralance transcribes the spoken audio automatically, so you do not type a word of the script yourself.
- 02
Pick language and style
Choose the transcription language, then set the font color, highlight color, and on-screen position to match your brand or platform.
- 03
Burn in animated captions
Captions render with karaoke-style word-by-word highlighting and are burned directly into the video frames for 3 credits.
- 04
Download and publish
Get a file with captions baked in, then download it and upload it yourself to TikTok, Reels, or Shorts. Source videos can be up to 5 minutes long.
Why creators use it
- Costs 3 credits per video, with captions burned directly into the frames so they display on every player without a separate subtitle file
- Karaoke-style word highlighting lights up each word as it is spoken, which keeps viewers reading and watching longer
- Automatic transcription removes manual typing and timing, since the audio is converted to timed captions for you
- Burned-in captions make videos watchable with the sound off, which is how most TikTok, Reels, and Shorts feeds play by default
- Full styling control over font color, highlight color, and caption position so text stays readable over any footage
- Multi-language transcription lets you caption clips in the language your audience actually speaks

Frequently asked questions
How do I add captions to a video automatically?
Upload your video to Viralance and the Auto Subtitles tool transcribes the spoken audio into timed captions, then burns them into the video. You pick the language, font color, highlight color, and position, and it costs 3 credits per video.
What are karaoke-style captions?
Karaoke-style captions highlight each word in a different color the moment it is spoken, instead of showing a full static line. Viralance applies this word-by-word highlighting automatically, and you choose the highlight color yourself.
Do auto subtitles get burned into the video or saved as a separate file?
Viralance burns the captions directly into the video frames, so they appear in any player and on any platform without needing a separate .srt or .vtt subtitle file.
Can I change the caption color, font color, and position?
Yes. Before rendering, you set the font color, the karaoke highlight color, and where the captions sit on screen, so the text stays legible over your specific footage.
How much does it cost to add subtitles to a video on Viralance?
Auto Subtitles costs 3 credits per video. That covers the automatic transcription, the karaoke-style animated highlighting, and burning the captions into the final file.
Do captions actually improve video performance?
Captions let people watch with the sound off, which is the default for most TikTok, Reels, and Shorts viewing, and the word-by-word highlighting helps hold attention. Together that supports longer watch time and makes videos accessible to viewers who are deaf or hard of hearing.
