Get a Subtitle File for Your Video

Upload a video and ScreenApp transcribes the audio, then lines the text up with timestamps so it downloads as a subtitle file. You get the SRT or VTT file to add to your video on YouTube, in your editor, or on whatever platform you publish to.

ScreenApp does not burn the captions into the video for you yet, burned-in (open) caption export is coming soon. Until then, if you want captions permanently visible in the frame, add the SRT or VTT file in your video editor, or use YouTube’s own caption uploader, both of which accept the file directly. Once a caption is burned in it cannot be fixed without re-exporting, so if the file came from elsewhere or you have nudged the timings by hand, run it through the subtitle quality checker first.

How to Add Subtitles to a Video

  1. Upload your video: drag in an MP4, MOV, AVI, WebM or similar file, or paste a video link.
  2. Get the transcript: ScreenApp transcribes the audio and matches it to timestamps.
  3. Download the subtitle file: export as SRT or VTT and add it to your video in YouTube, your editor, or the platform you publish on.

Accuracy depends on the audio. Clear, single-speaker narration transcribes best; overlapping speech or heavy background noise leaves more to review. See how we measure accuracy.

Who Adds Subtitles to Video

Content creators transcribe a video once and get a subtitle file to upload alongside it on YouTube or another platform that reads SRT and VTT natively.

Businesses caption product demos and training videos so viewers can follow along with the sound off, then attach the subtitle file when they publish.

Educators turn a recorded class or webinar into a transcript first, then export the subtitle file for students who need to read along or use a screen reader.

Social media managers get a transcript and subtitle file for a video meant for feeds where autoplay starts muted, then add the captions through the platform’s own uploader.

International teams transcribe a video and use caption translation to produce a subtitle track for a different market without re-recording anything.

Podcasters publishing video versions transcribe the recording and export a subtitle file to attach to the video upload, instead of typing captions by hand.

FAQ

Can I add subtitles to a video for free?

You can transcribe a video and export the subtitle file on ScreenApp's free plan, which covers 2 transcriptions of recordings up to 45 minutes each. Adding that SRT or VTT file to the video itself happens in your editor or the platform you upload to.

Does ScreenApp burn the subtitles into the video?

Not yet, burned-in (open) caption export is coming soon. Today, ScreenApp gives you the transcript and the subtitle file as PDF, DOCX, TXT, SRT and VTT. To have the captions show as part of the video frame in the meantime, add the file in your video editor or through YouTube's caption uploader, both of which accept SRT and VTT directly.

How do I add an SRT file to a video?

Export the SRT file from ScreenApp, then upload it in your video editor's subtitle or caption panel, or in YouTube Studio under Subtitles. Most editors and platforms sync it automatically using the timestamps already in the file.

What video formats can I upload?

Upload MP4, MOV, AVI, WebM, MKV, or similar common video formats. ScreenApp transcribes the audio track regardless of the video container.

Can I get subtitles in another language?

Yes. ScreenApp offers transcript and caption translation, so you can produce a subtitle track in a second language from the same recording.

What's the difference between subtitles and closed captions?

Subtitles transcribe or translate the dialogue. Closed captions add descriptions of sounds, music, and other non-speech audio for viewers who can't hear them. ScreenApp's transcript covers dialogue; sound-effect descriptions are not generated automatically.

How accurate is the automatic transcription?

Accuracy depends on audio quality. Clear, single-speaker audio transcribes best; background noise, overlapping speakers, or a poor recording setup reduce it. See how accuracy is measured.

Does the subtitle timing match my video exactly?

Timestamps are generated from the audio track itself, so they line up with your video's timeline as uploaded. If you trim or re-edit the video afterward, re-export the subtitle file so timing still matches.
