AI Subtitle Generator for every platform

Record with the music low or off: background music in the recording itself makes any transcription less accurate. Music you add in Jupitrr comes in after transcription, so it doesn't affect the subtitles. If a transcript comes back wrong, use Regenerate subtitles and try another model or set the language.

Several tools offer animated keyword highlighting, including CapCut and Jupitrr AI. The key difference is control: some tools auto-highlight based on emphasis detection, while others let you manually tag words. For brand consistency, look for tools that let you save highlight rules (color, font weight, animation style) as a reusable template.

Look for tools with saved caption styles - font, size, color, position, background, animation - that you can reuse on every video. Jupitrr has 24 subtitle styles built in, and Save Style keeps your tuned version so you can reuse it on every video. This is critical for teams producing 10+ videos a month who cannot afford to manually style every clip.

The standard safe zone for vertical (9:16) video captions is the lower third - roughly between 70-85% from the top of the frame. Avoid center placement, which cuts across the face in talking-head content. In Jupitrr, drag Position in the Style view to move subtitles up or down, and check the preview before exporting.

You need two things: SRT/VTT export for platforms that render their own captions (YouTube, LinkedIn), and burned-in rendering for platforms that do not (Instagram Reels, TikTok). Jupitrr AI supports both from the same project.

Jupitrr adds punctuation as it transcribes. It doesn't cut filler words out of your audio; if an "um" shows up in the subtitles, delete it in the Transcript view and the subtitle updates while the video stays as recorded.

Use bilingual subtitles. After transcription, open Subtitles > Transcript, turn on Bilingual and pick one of 31 languages, and a translated line appears under each original caption. Translation runs sentence by sentence and is timed to your speech. Export both lines burned-in or as a bilingual .srt.

Bulk captioning requires both API access or batch upload, plus template-locking so every output matches your style. Jupitrr keeps styling consistent across your videos with Save Style. For high-volume teams processing 50+ videos at once, contact [email protected] for a customized setup.

Each platform has different UI elements that overlap your video - TikTok has a bottom action bar, Instagram has a username strip, YouTube Shorts has a bottom gradient. The universal safe zone is 15-80% vertically and 10-90% horizontally. In Jupitrr, set subtitle Position so captions sit clear of those areas, and check the preview before exporting.

Use custom vocabulary. In Jupitrr, add names and brand terms to Vocabulary when you upload (up to 20). If one still comes out wrong, use Find and replace in the Transcript view to fix every instance at once.
