MP4 · Max 100 MB per file · Checking the file length limit…A recording, then a written draft
A saved presentation, interview or spoken tutorial can provide source material for notes, quotations or a document draft. This workflow uses speech in the first audio track of an MP4 file. It does not interpret the pictures, so a reference such as “this chart” still needs a manual check against the original video.
MP4 is the video format for this workflow. For an audio-only export, use an existing MP3, M4A or WAV page. A video URL, MOV, AVI or WebM file is not an MP4 upload. Use your recording or editing app to export a supported file you have permission to process.
The free allowance
Guest use is included in the account total when linked. These cloud minutes do not renew monthly. There is no separate allowance for each page.
See current plans and file limits →Step by step
Play the recording and check that the intended speech is audible. Choose one MP4 within 100 MB and the duration limit shown in the uploader. If there are several audio tracks, export the intended track when it is not first.
Cloud processing extracts the first audio track before speech recognition. The selected audio duration is rounded up to whole seconds for usage, rather than using the full video length. Keep the page open while processing. A silent visual track cannot supply spoken words.
Replay important passages to correct names, figures and quotations. Make your edits in the text editor, then copy the latest text or trigger a UTF-8 TXT download. Keep your own saved copy; result retrieval is temporary.
A look at the result
Owned synthetic video with two audio tracks. The speech below is a manual punctuation edit of the first-track script, not a returned provider transcript or an accuracy benchmark. Play the extracted first audio to hear exactly which track is used.

This manual edit splits the source script into shorter sentences for readability. It is a reference for the synthetic first audio track, not an observed recognition result. If quoting a real speaker, compare every quoted passage with your own recording.
If several people speak, identify them yourself while replaying the recording. Add names only where you can verify who spoke; overlapping voices may leave uncertain words.
Check technical terms and references to slides or actions. Add a description of a visual yourself when your notes need it; a speech transcript alone cannot explain what was on screen.
Listen to the selected track. If music masks speech or the microphone was distant, an original separate microphone track may help. A larger export cannot restore words that were never recorded.
Check size and the intended audio-track length separately. Export a shorter relevant clip if it exceeds the shown limit. Keep the original and use a proper export action if the file cannot be opened; renaming its extension does not convert it.
Questions
No. The output is editable plain text from speech. OCR, visual descriptions, automatic summaries, speaker labels, timestamps and SRT or VTT subtitle files are not included. Add headings or labels manually after checking the source.
The cloud allowance is up to 10 cumulative guest minutes. A free account has up to 30 lifetime minutes in total, including linked guest use. Using all 10 guest minutes leaves up to 20 account minutes. It does not renew monthly; audio and MP4 share the same balance.
This upload workflow requires a file from your device. It does not download video links or import captions. Export an MP4 with the intended audio, or a supported audio file, from a source you are allowed to use.
Cloud processing uses private temporary upload storage and a speech transcription provider for the extracted audio. Check the Privacy page for current retention and deletion details, and avoid uploading confidential material without the necessary permission.
