## How it works

1.  ### Upload your file

    In Speechyou Notes, select Upload, choose your recording, and select Upload & transcribe.

2.  ### Review the transcript

    Open the finished note and listen for names, technical terms, and changes of speaker. Check those passages again in the exported captions.

3.  ### Export Subtitles (.srt)

    Choose your subtitle format from Export when the transcript contains timed segments. Check the cue timing in your editor or player.

Accepted extension .mp4

## Export guide

### Use the same MP4 you plan to publish

Export the finished MP4 from your editor with the narration or dialogue audible. Transcribe that file in Speechyou. The resulting SRT uses the MP4 playback timeline, so use the matching version when you add the captions to YouTube or another supported destination.

### Deliver the caption track alongside the MP4

Name both files after the same project so it is clear which caption track goes with the video. Preview them together and check the first cue, any long pauses, and the final line before uploading or handing off both files.

### Upload an SRT with timing in YouTube Studio

Open the video in YouTube Studio and go to its subtitles. Select the language, choose to upload a subtitle file with timing, and pick the downloaded SRT. Review the captions against the uploaded video before publishing so you can catch a language mismatch or an edit made after transcription.

### Troubleshoot an MP4 caption track that looks out of sync

If the captions are equally early or late from beginning to end, compare the lead-in of the uploaded MP4 and the copy you transcribed. If they fall further behind as the video plays, check for cuts, playback speed changes, or a different export. Generating cues from the uploaded version gives you one timeline to review.

### Publish a captioned MP4

-   Save the MP4 and SRT under the same project name and version.
-   Choose With timing when adding the SRT in YouTube Studio.
-   Check the intro, one mid-video exchange, and the last spoken line in the published player.

## Frequently asked questions

Do I need to extract the MP4 audio first?

No. Upload the MP4 directly. Speechyou transcribes its audio and offers SRT export when timed speech segments are available.

Can I edit the SRT after downloading it?

Yes. SRT is a plain-text format. Open it in a subtitle editor to adjust wording, line breaks, or timing.

Can I attach the same SRT to a re-edited MP4?

Only reuse the track if the dialogue still occurs at the same playback times. If the edit moves or removes speech, retime the cues or generate a new SRT for that version.
