Captions that keep people watching
A lot of people scroll with the sound off, so the captions decide whether they stay. Sleepy Motion turns what is said into captions that pop in on every word, in your fonts and colors, with sound effects timed to them.
Two styles: Classic puts the captions on top of your video, and Composite cuts you out and puts them behind you, the depth look from high-end edits.
How to add captions to a video
Upload your video
An MP4 up to 150MB, vertical or horizontal, up to 30 seconds (2 minutes on the Agency plan). Sleepy listens to what is said and writes the captions for you.
Pick a style and a language
Classic puts animated captions on top of the video; Composite puts them behind you. Keep the language spoken or pick another one to translate the captions. Paste your script if you want it word for word.
Download
Every word lands on time, with sound effects added for you. Download in 1080p, vertical or horizontal. Something to fix? Edit the words and timings and retry.
Questions
How do I add captions to a video automatically?
Upload your video to Sleepy Motion. It transcribes the speech, times every word and animates the captions on the video for you. No typing and no timeline.
Can I add subtitles in another language?
Yes. Pick a caption language and the captions come out in it, translated from what is said. Picking the language actually spoken helps the transcription be even more accurate.
How accurate are the captions?
They are transcribed from the speech and timed word by word. For a word-perfect result, paste your exact script before you generate. After it is done you can still fix any word or timing in the editor and retry.
Can the captions go behind me instead of on top?
Yes. Choose Composite and Sleepy cuts you out on every frame and places the captions behind you, the depth look from high-end edits.
Does it work with horizontal videos?
Yes. Upload vertical or horizontal footage, and get the captioned video back as a vertical 9:16 short or a horizontal 16:9 video.
Can it cut the pauses and mistakes too?
Yes, on the Agency plan. Turn on AI edit and Sleepy cuts the silences, mumbles and wrong takes before it adds the captions, so a rambling take comes back tight.
Is it free?
Captions come with every paid plan, starting with Starter at $5 a month. You can make motion graphics videos for free before you upgrade.
