Caption Extractor
Read, search, and copy captions already attached to a public video.
Caption text for research and review
Extracting an existing caption track makes spoken content easier to inspect, quote, or review. Captions can contain errors introduced by the source, especially automatically generated text. Verify significant passages against the original video.
Plain text and timed captions
Read the text or search individual caption segments. Copy the returned text and save a TXT export. Timed SRT and VTT outputs appear only when all returned segments have valid timing and the response is not truncated.
Extraction has source limits
A missing caption track, expired result, unavailable language, or platform restriction is shown as a real limitation. New transcription and other account-based processing continue in Genooi rather than through an anonymous ASR request.
Caption Extractor FAQs
Can I copy video captions as plain text without their timestamps?
Yes. When a supported public link returns captions, Copy text and TXT export use the available plain text. SRT and VTT retain cue timing when a complete valid timeline exists. A partial result contains only the returned portion and is clearly labelled.
Can I search the extracted captions for a phrase?
The result includes a text search that filters the visible caption segments. It helps locate a phrase in the returned track, but it does not search parts of the video that have no caption text. Copy and export still use the returned transcript, not a newly generated transcript.
What is the difference between extracting captions and transcribing speech?
Caption extraction retrieves text that already exists at the source. Speech transcription creates new text from an audio recording. This page only performs the former; when a track is missing, you can continue to a separate signed-in transcription workflow in Genooi.
Why does the extractor return only part of the caption text?
The media service can return a truncated track rather than a complete transcript. MoiMobi marks that result as partial, exports only available text in TXT, and disables timed subtitle exports. It does not fill missing lines with guesses or hide the incomplete state.
Can Caption Extractor read subtitles visible inside a video frame?
Only a separately available caption track can be extracted here. Text drawn into the picture is not a downloadable text track, even when it looks like subtitles. The extractor has no frame OCR, translation, or automatic speech-recognition fallback.
