Opencast Video Editor

The Opencast Video Editor is a tool included by Opencast to cut and arrange recordings.

Quick Test

To test locally, run:

npm start

This will start a local test server in the development mode. Open http://localhost:3000 to view it in the browser.

The latest version connected to develop.opencast.org is also publicly available at editor.opencast.org.

To open a specific event with the editor, use the GET-Parameter id like so: https://editor.opencast.org/?id=27cd7156-fda6-4b31-aab5-d56833012caf.

Building the Editor

To build the editor for production to the build folder, run:

npm run build

To make the editor work in a sub-path, use:

PUBLIC_URL=/path npm run build

Configuration

The editor can be configured through the editor-settings.toml settings file. It can either be provided in the public folder when running locally or can be found under etc/opencast/ui-config/mh_default_org/editor when deployed in Opencast. More information can be found in the example configuration file.

How to cut a release for Opencast

0. Make sure all merged pull requests have proper type: labels. They are used for generating the release notes.
1. Switch to the commit you want to turn into the release
2. Create and push a new tag

   git tag -s 2021-11-27
   git push upstream 2021-11-27:2021-11-27
   

3. Wait for the Create release draft workflow to finish
   • It will create a new GitHub release draft
   • Review and publish the draft
4. Submit a pull request against Opencast
   • Update the release
   • Adjust the documentation if necessary
   • Update the configuration if necessary
   • Verify that the new release runs in Opencast, then create the pull request.

Opencast API used by the Editor

The editor accesses the following endpoints in Opencast:

• /editor/<mediaPackageId>/edit.json (introduced in OC 9.3)
• /editor/<mediaPackageId>/metadata.json (introduced in OC 9.4)

If you want to use current editor frontend with an earlier Opencast version, you will have to cherry pick the relevant commits from the Opencast repository yourself.

Translating the Editor

You can help translating the editor to your language on crowdin.com/project/opencast-editor. Simply request to join the project on Crowdin and start translating. If you are interested in translating a language which is not a target language right now, please create a GitHub issue and we will add the language.

Configuration

Configuration Methods

Most configuration options can be set either as a URL parameter or as an option in the configuration file.

If the option belongs to a section, URL parameters are a combination of section and option separated by a single dot.

For example, the following option in the configuration file:

[trackSelection]
show = true

…can be specified as URL parameter in the form trackSelection.show=true.

If an option can be specified both ways, the URL parameter will always take precedence.

Settings

Options which are usually specified in the configuration file are documented in there as well. Metadata configuration options are only documented in the configuration file.
