01 / The idea
The useful moment, not the whole file.
Sharing a ten-second highlight should not mean uploading a forty-minute recording first. Save Replay moves the cut to the browser, where people can preview and select the exact range before any video is transferred.
The result is a focused tool rather than a full editor: less waiting for the sender, less data moved, and a clean watch page for the recipient.
02 / Product flow
Three steps. One link.
- 01
Choose
Open a recording and preview it instantly on-device.
- 02
Trim
Select the useful moment on a visual timeline.
- 03
Share
Upload only that clip and get one short link.
The original stays local while the useful range is selected and prepared.
The same short URL moves from processing to ready-to-watch.
03 / Behind the simplicity
A small interface backed by a complete video system.
Browser-side preparation, multipart uploads, background processing, adaptive streaming, and privacy-aware access all work together so the primary journey stays simple.
- Local-first Browser preview and clip preparation
- Reliable MP4 fallback with adaptive HLS playback
- Private Public, unlisted, protected, or owner-only
