Echo360 Captions tekijä spuddydev

Echo360 hosts lecture videos and shows a transcript panel beside the player, but it does not surface those transcripts as captions on the video itself. That makes lectures hard to follow when you are watching at speed, in a noisy room, with the volume off, or when reading along is simply easier than listening.

Echo360 Captions adds a small CC button to the Echo360 player. Toggle it on and the active transcript line is rendered as a caption overlay directly on top of the video, exactly where captions belong. Toggle it off and the overlay disappears. Captions follow the player into and out of fullscreen, and dual-stream layouts are handled.

Captions only work while the Echo360 transcripts panel is open, since Echo360 only mounts the transcript text into the page when that panel is the active sidebar tab. The extension opens the panel for you on load. If you close it mid-lecture, click the Transcripts button in the player controls to restore captions.

The extension only runs on echo360.net.au pages. It declares no permissions, makes no network requests, and does not collect, transmit or store any data. All processing happens locally in your browser using the transcript that Echo360 already renders on the page.

This was developed and tested with the intention of working for the University of Western Australia's Echo360 deployment. Echo360 is a general lecture-capture platform used at many institutions and the extension should work wherever the player and transcript layout match. If it does not work for your institution, please open an issue with a snippet of the relevant page markup so that the selectors can be widened (github.com/spuddydev/echo360-captions/issues)
