Key capabilities
What makes Add Subtitles to a Video in Blazescribe stand out.
Captions in minutes
No typing line by line. The transcript becomes timed captions automatically, so you start from a finished draft.
Edit and re-time
Rewrite any line, nudge the start and end in small steps, and merge or split segments so each caption reads cleanly.
Six styles, your colors
Style captions with six presets plus size, position, and color, previewed live on the video before you export.
Any format you need
Download SRT for YouTube and editors, VTT for the web, or a burned-in MP4 for TikTok, Reels, and Shorts.
Adding subtitles to a video used to mean either typing every line by hand in a desktop editor or paying a service and waiting a day. Neither is necessary anymore. Upload your video to Blazescribe and the audio is transcribed with word-level timing, then split into caption lines that already fit on screen. From there it is cleanup, not creation: fix a name, tighten a line, nudge a timestamp that drifted. When the words are right, choose how the captions look with six styles plus size, position, and color, and watch the changes live on the video. The last step is your call. Download an SRT for YouTube and editors, a VTT for the web, or a burned-in MP4 for TikTok, Reels, and Shorts where captions have to be visible the moment a muted clip starts playing. No install, no waiting, no watermark.
