The working surface

Your recording.
Your explanation.

The video and your steps stay side by side. Nothing is uploaded by the media processing code. Closing or reloading the page loses unsaved work.

Your recording

Use authorized, redacted footage. No secrets or customer data.

Silent clip export

1280×720 letterboxed silent output. Manual captions show at the bottom. Real time render; no MP4 or audio. Only browsers supporting canvas/MediaRecorder.

Make the steps yours

Choose the moment yourself. Review the step against the recording.

Choose a recording to begin.

Your guide starts with a recording.

Choose an authorized file, then write the steps in your own words.

Use authorized, redacted footage. No secrets or customer data. Outputs need your review before sharing.

A manual workflow, on purpose

Make the pause
part of the explanation.

For a shop walkthrough or a team process, the useful part is often the detail that automatic polish would skip.

01

Choose a recording.

Use an existing local video of up to 60 seconds and 50MB. Keep the file authorized and redacted.

02

Write the steps.

Set each start and end time. Describe only what the recording shows. Check each caption against the source.

03

Export and review.

Create Markdown, HTML and SRT files. A supported browser can also render a silent WebM clip with your manual captions.

The scope is part of the product

A small tool.
Clear boundaries.

Does it generate video from a prompt?

No. It works with an existing local recording and your manually entered steps.

Where is my recording processed?

In the browser. The media processing code does not upload the recording. Hosting still receives normal page requests.

Can I get voiceover or automatic captions?

No. Caption text and timings are manual. WebM export is silent, not a narrated marketing video.

What can I export?

A Markdown guide, an HTML guide and an SRT caption pack. Supported browsers can render a letterboxed 1280 by 720 silent WebM clip in real time.

Will my work remain after closing the page?

No. Download your outputs before leaving. Reloading or closing the page loses unsaved work.

Can I buy recording help?

Human services are available by invoice after scope agreement. The service scope page describes the starting scope. There is no checkout or secure intake on this site.

Keep the source in view.
Review every step.

A local guide helper, not a governed enterprise content platform.
