How to add automatic subtitles to a screen recording
Captions make short explanations easier to watch without sound and help viewers find important moments. Recsavo recognizes English and Russian speech locally in your browser and lets you correct the results.
1. Record clear narration
Speak into a microphone with minimal background noise, then open the resulting video in the editor.
2. Generate captions
Open the subtitles tool and choose Create subtitles. The first time you request recognition, Recsavo downloads a language model of approximately 76 MB. Speech processing then takes place on your device.
3. Proofread the transcript
Check names, product terms and numbers: automatic recognition can make mistakes. Correct individual words before exporting. Consider a cleaner source recording if the background is very noisy.
4. Choose the output format
Save standalone SRT or VTT captions, or include subtitles in the MP4 itself. Burned-in captions are useful for silent viewing, while a separate caption file is useful for subsequent editing.
Common questions
Is my voice sent to a cloud AI service?
No. The model is downloaded when you request it, and the speech is processed locally in your browser.
Can I correct captions?
Yes. You can edit the generated text before exporting the video or subtitle file.
