Panopto Plus Extension

Panopto Plus adds a few features to the webcast page on NUS Panopto websites. These changes also apply to webcasts on LumiNUS. It also allows you to customize your webcasting experience.

The Chrome Extension serves 3 main purposes:

1. Add transcript and subtitles to (most) of your webcasts

2. Add silence trimming. Sections in the webcast where there is no speech are automatically skipped.

3. Add various user interface improvements:
o Wider range of webcast playback speeds with a slider / more options
o Persistent settings across all webcasts / webcasts under a module e.g. always start playing webcasts at 2.0x speed
o Volume Booster to amp the volume up beyond the maximum when it's too soft
o Minimizable sidebar for all webcasts (you can now split screen with all webcasts)
o Carousel customization

Additional features include:

a. White noise reduction & audio normalization

These features are toggleable and customizable on the settings page.

Panopto Plus is a free open-source project licensed under GPL-3.0 that belongs to NUS and was developed as an NUS Orbital project. You can access the GitHub repository here: https://github.com/crazoter/panplus
