E-SEC Authoring Support

Appearance

Asset manager ​

The asset manager is where you upload and select the media files used in your course. Open it with the button in the bottom-left of the edit panel; it slides up beneath the edit panel.

TIP

You can also open the asset manager by double-clicking a component on a slide.

Tabs ​

The asset manager is split into four tabs along the left edge:

  • Images — your uploaded image files. Supported formats: JPG, PNG, GIF, SVG, WebP.
  • Videos — your uploaded video files. Most common formats are accepted (MP4, MOV, MKV, WebM, OGV, and others). Each video file must be 2 GB or smaller. Uploaded videos are encoded into standard playback formats afterwards, which runs as a background task.
  • Icons — pick from a built-in icon library. Icons are not uploaded; they're shared across all courses.
  • Audio — your uploaded audio files. Supported formats: MP3, AAC.

Toolbar ​

At the top right of the asset manager:

  • Search — filter the current tab by file name.
  • Refresh — reload the list. Useful when another author has uploaded something while you were working.
  • Upload — pick one or more files from your computer to add to the current tab. Not available on the Icons tab.
  • Close — closes the asset manager.

Using an asset on a slide ​

  • Drag an asset tile from the asset manager onto a slide to add a new component using that asset.
  • If you opened the asset manager by double-clicking an existing component, clicking an asset swaps the component's asset to the one you picked.

Per-language assets ​

Most assets are language-agnostic — you pick one and it's used for every language the course is published in.

The exception is video. Each video element has its own audio language, and can carry subtitle files for one or more languages. There's no concept of a single video with multiple audio tracks, so if your course is dubbed, upload one video element per language and use the per-language assignment described in Course localization.

Limitations ​

Renaming and deleting assets from the asset manager is not currently supported. To stop using an asset, swap it out on the slide and leave the unused file in the library.
