Transcribe a video already saved from Instagram
This guide is for an existing local video you may process. Public-link retrieval has its own Instagram Transcript Generator walkthrough.
1. Check the file, audio and coverage
A local video is different from a saved post or web shortcut. Play the intended passage and keep its source reference separately. A picture without audible speech cannot supply a spoken transcript.
Check: The recording includes the words you need.
Continue in the matching tool2. Use the local video workflow
Open Video to Text for one browser-decodable file up to 100 MB. Recognition supports English only, with language checks before transcription. Local media stays in the browser; model resources are downloaded as needed.
Check: You selected a real media file rather than pasting a platform URL.
Continue in the matching tool3. Keep visible words separate from speech
Replay and correct the transcript, then save TXT/Markdown or valid SRT/VTT. The tool does not read a post description, comments or text printed on the video. See Caption Extractor to choose the appropriate text source.
Check: The exported transcript represents speech, with other sources clearly identified.

What processing and privacy boundaries apply?
Local decoding, recognition, replay, edits and downloads run in your browser. Model resources need network access, but the local recording and transcript are not uploaded. There is no account history or saved cloud project; download your work before closing the tab. Same-origin editor transfer keeps the cues and recording local between tabs. Instagram URL retrieval and YouTube caption lookup have separate server-assisted privacy boundaries.
Where should I continue?
Open the matching tool and follow its current input requirements. Keep the original, review your result and download it before closing the tab.
Historical measurements and method limits
How long does Instagram video to text take?
These are historical measurements from 2026-09-14 using only whisper-tiny.en. They do not measure the current language-detection plus English-transcription workflow, and exclude Instagram lookup and media download.
| Audio length | Historical wall-clock time | Historical model load |
|---|---|---|
| 11 s | 16.89 s | included |
| 11 s | 6.49 s | already in memory |
| 30 s | 8.98 s | already in memory |
| 60 s | 16.06 s | already in memory |
| 120 s | 28.58 s | already in memory |
In the historical test, the first run included model loading; subsequent runs retained the English model in memory. Current jobs release that instance before language detection, so a resource cache hit still requires initialization. Wall-clock time is not CPU time, and subtracting two runs does not isolate download or initialization time.
One machine, one WASM browser, one run per historical data point. Audio clips were constructed from a repeated public JFK recording. These rows do not predict today's end-to-end time, other devices or other recording content.
