Manual subtitling means spotting every cue, typing every line, and nudging timecodes until they match the audio — hours of work per video. The Recapo auto subtitle generator removes that entire layer: speech recognition finds the dialogue, splits it into cues, times each one, and burns the subtitles straight onto the picture.
What you get back is not a file to wrangle in another tool — it's a finished video. Upload a clip, let it process, then preview the captioned result and download the MP4 right here on the page.
Processing runs on this page — don't leave while it's running, or the task is cancelled.
Zero manual timing, start to finish
Everything that used to require a timeline scrubber is automated: the generator detects where speech starts and stops, breaks it into readable cue lengths, writes the timecodes, and renders each line onto the video. The output is a captioned video you can publish as-is, not a transcript you still have to sync.
- Speech detection times every cue's appearance automatically.
- Sentence segmentation keeps lines short enough to read on screen.
- Subtitles are burned into the picture, so they show on any player without a separate file.
From raw clip to captioned video in one pass
If you publish weekly episodes, clip podcasts, or maintain a course library, hand-subtitling each video is the bottleneck. Upload the clip, let recognition transcribe and time the dialogue, and the subtitles are baked onto the picture for you — your role shrinks from transcriber to a quick reviewer. Processing draws on credits; the pricing page has the details.
How to use the Recapo auto subtitle generator
Three steps, fully in the cloud — nothing to install.
Step 1: Upload your video
Drop in a single clip. The auto subtitle generator reads the audio track straight from the video — no separate caption file to prepare.
Step 2: Let recognition run
Speech is transcribed, segmented, and timed without any manual spotting, then the subtitles are rendered onto each frame of the video automatically.
Step 3: Preview and download
Watch the captioned video right on the page to check the wording and timing, then download the finished MP4 with subtitles burned in.
Frequently asked questions about the auto subtitle generator
Do I have to set start and end times for each line?
No. Timing is generated automatically from the audio and the subtitles are placed on the video for you. There is no timeline to spot by hand.
What do I get back — a subtitle file or a video?
A video. The captions are burned into the picture, so you download a finished MP4 that already shows the subtitles on any player.
What happens when the transcription gets a word wrong?
Misheard words are the normal cost of noisy audio or niche jargon. Preview the captioned result before you download, and if a clip needs a cleaner take you can re-run it with better audio.
