Timing checked twice
The whole video is transcribed once, then each chosen passage is transcribed again word by word. Where the two do not match, the caption keeps the first timing and is marked as estimated so you know to check it.
SHORTS CAPTION GENERATOR
Generate word-timed subtitles burned into your YouTube Shorts.
shortshort captions the shorts it cuts from your long video: every word placed on the moment it is said, in the language spoken, in one of four styles. It is a step of the same studio, not a standalone subtitling service. These are captions burned into the video as subtitles, not the text you write under your post.

Why the studio fits this job
The rules of the studio that matter most here.
Four styles, each with a different job
Spotlight highlights the spoken word in uppercase, Impact sets bold uppercase lines with one highlighted word in each, Karaoke lights words up as they are said, Minimal stays quiet with no effect.
Your own SRT is accepted
An SRT file timed to the source video replaces the studio's own transcription on every short.
The four caption styles, in motion
Each style on a line of its own, all timed the same way. The community below shows real exports.
How to do it
Four steps. About two minutes of your time; the processing itself runs on our servers and depends on the length of the video.
- 01Upload the long video the shorts will be cut from, MP4, MOV or WebM, up to 2 GB
- 02Let the AI pick the passages, then adjust their bounds in the editor
- 03Choose one of the four caption styles and set colour and font for the video
- 04Check the timing on each short, then export the MP4 with the captions rendered on it
What this page does not promise
What the search term usually implies, and the studio does not do.
No standalone captioning: a video uploaded only to be subtitled still comes out as shorts aimed at 15 to 90 seconds.
No translation and no dubbing: captions stay in the language spoken, with no second-language track and no synthetic voice.
On a real video, in the same studio
A published transformation from the community: the original on top, the shorts it became below, with the transcript of each short.

Questions people ask
Are these auto captions or subtitles?
Both words mean the same thing here: text drawn into the MP4, timed on each spoken word. You can also import your own SRT timed to the source, and Export captions in the studio saves each short's captions as an SRT file timed to the short, on every plan.
Which languages do the captions support?
Captions are in the language spoken in the video, never translated: each short's words are transcribed by OpenAI's whisper-1, which OpenAI says supports 98 languages, with accuracy that varies by language, so check the words before rendering.
How accurate is the timing?
Each word of a selected passage is timed in a dedicated second pass on the audio. When that pass cannot line up with the first transcription, the original timestamps are kept and marked as estimated, so you know which captions to check in the studio.
Can I use captions I already have?
Yes. Import an SRT file timed to the source video and the studio uses those cues on the shorts instead of its own transcription.
Can captions be styled to match my brand?
Yes. Every plan lets you pick the caption colour and the font for each video before rendering. The Studio plan goes one step further and stores that choice as the account's brand preset, a single one per account, applied by default to every new video.
Can I caption a video without cutting it into shorts?
No. The captions are a step of the shortshort studio and apply to the shorts it produces, each aimed at 15 to 90 seconds. A one-hour video uploaded for captions alone would still come out as shorts.
Which style should I pick for a talking-head short?
Spotlight is the default: uppercase text with the word being said highlighted in turn, which follows the rhythm of speech. Impact suits a clip built around one number or claim; Karaoke suits explanations; Minimal suits clips where the picture matters more than the words.
A 31-minute interview on Creator, 6 shorts, one upload.
Free to try with 30 credits. Your upload stays private until you export; exported shorts join the community with their source video by default, and any paid plan can keep them out.
