Transcription guide

Download the finished browser recording

Save the WebM file after the recorder finishes exporting it. A browser capture can include microphone audio, tab audio, or both, depending on the permissions you selected when you recorded. Play a few seconds from the saved file so you can hear the source you intend to transcribe.

Review the transcript as you follow the demo

Spoken walkthroughs often refer to actions that are only visible on screen. When you reuse a WebM transcript for training, add the actual names of buttons and menus to the relevant passages after checking the recording. Leave cues in sequence so someone can follow the walkthrough without guessing which screen comes next.

Add captions to the browser player

Choose a plain text download for an article or knowledge base. If you plan to publish captions in an HTML video player, export WebVTT when your note has timed segments. Keep that file next to the WebM in your publishing workflow and check a cue at the beginning and near the end.

Tell a capture problem from an export problem

Browser recorders may keep the microphone and the shared tab on separate tracks, or mix the sources into one. Check the saved WebM in a player. If you hear the presenter but none of the sample audio they play, check whether tab audio was captured. If you hear the sample but no narration, check the microphone setting in the original recording tool. A new export can include a track that exists in the source. When the recording itself never captured it, use a separate narration file or record the passage again.

Check a browser recording

Wait for the recorder to finish exporting the local WebM.
Listen to a section with microphone narration and a section where the tab plays sound.
Check that the version you caption includes the same title screens and cuts as the published copy.
For HTML playback, test the WebVTT cue timing in the destination player.

Frequently asked questions

Why is speech missing from my WebM screen capture?

Play the local file and check whether you can hear the microphone or the browser tab. If one is missing, return to the recorder and enable that audio source when capturing or exporting again.

Does a WebM file have to contain video?

WebM can contain audio with or without a video track. Speechyou uses the audio in the supported file to produce text.

Can I make WebVTT captions from the same WebM recording?

Yes. After transcribing the WebM, select WebVTT from Export when timed segments are available. Preview it in the destination player to verify that cues match the source.
