Outlined phrase captions
A fixed lower caption zone keeps bold text readable while the speaker and background continue moving.
Animated captions that move with the spoken words.
Turn speech into timed captions, choose how phrases enter and active words stand out, and preview the result on the real video before you export.

How it works
- 01
Upload a video with speech
Start with an MP4, MOV, WebM, or MKV. Free supports clips up to 10 minutes and 500 MB.
- 02
Generate and correct the captions
Automatic transcription creates timed segments. Review names, punctuation, wording, and line breaks before designing the motion.
- 03
Choose a caption treatment
Start from a preset, then adjust typography, emphasis, entrance motion, position, and the amount of text shown together.
- 04
Preview and export
Watch the captions against the final footage, keep important visuals clear, and export a watermark-free MP4 or separate subtitle file.
Caption inspiration
Motion should help viewers follow the sentence.
These reference clips show three practical approaches to captions in motion. Use them to judge pace, contrast, and placement, then build the treatment against your own footage.
Lightweight phrase emphasis
Smaller italic captions add motion and emphasis without turning every spoken word into a visual interruption.
Progressive word reveal
Words appear with the pace of the sentence while the caption block stays anchored away from the speaker's face.
Built for the correction after generation.
Motion tied to real word timing
The transcript includes word-level timing, so a style can emphasize the word being spoken instead of animating an entire paragraph on an arbitrary loop. That connection is what makes karaoke highlights, progressive reveals, and active-word treatments feel synchronized rather than merely decorative.
Phrase-level movement that remains readable
Not every caption needs one word at a time. Multi-word phrases can enter with a fade, slide, shift, grow, or pop treatment while maintaining a stable reading area. The goal is to give a viewer enough time to read the complete thought without covering the speaker or changing position on every cue. Faster speech usually needs calmer motion and fewer words on screen; a slow hook can support a more deliberate reveal. Treat the animation as part of the reading rhythm, not a separate effect competing for attention.
Preview motion on the actual composition
Caption timing and placement cannot be judged from a detached style swatch. Preview the treatment on the uploaded footage, where faces, graphics, camera movement, and platform controls affect whether the caption remains clear. Check the beginning, middle, and end rather than approving one attractive frame. Watch once with sound and once muted: the silent pass exposes missing context, rushed cues, and weak contrast. For vertical video, leave room near the edges for usernames, descriptions, and playback controls added by the publishing platform.
Edit the words before styling the mistake
Animation does not make an inaccurate transcript usable. Correct names, numbers, punctuation, and missed speech before the final export. Keeping the transcript and visual treatment in the same workflow prevents a polished caption style from hiding errors that will follow the video into every feed.
A finished export without product branding
The Free plan includes 3 watermark-free MP4 exports each calendar month at up to 1080P. The selected caption treatment is burned into the picture so its timing, typography, color, and motion remain visible wherever the video is posted.
Questions before upload
What are animated captions?+
Animated captions are timed on-screen words or phrases that change as speech progresses. Motion can introduce a cue, reveal words, or emphasize the active word while keeping the caption readable.
Can animated captions follow each spoken word?+
Yes. Word-level timing supports treatments that highlight or reveal speech as it happens. You can also choose phrase-based captions when a calmer reading experience fits the video better.
Can I edit the generated captions?+
Yes. Review and correct the transcript, line breaks, and timing before export. Animation should be applied to accurate captions rather than treated as a substitute for transcription review.
Will SRT or VTT keep the animation?+
No. Standard subtitle files primarily preserve cue timing and text, while the receiving player controls appearance. Export a captioned MP4 when the exact motion and visual style must travel with the video.
Do animated caption exports have a watermark?+
No. Free and Starter MP4 exports do not add an Auto Subtitle Generator watermark. The plans differ through limits and features rather than branding the finished video.
