Please check shortly before the conference if the schedule has changed.

If you are presenting and have a problem with the date and time your session is scheduled, please contact the conference committee.


Workshops will happen in the two weeks after the conference. They will be scheduled as part of the first session at the summit. Please join us at the planning session. We like to ensure that as many of you as possible can make it to the workshops.

The following workshops have been submitted:

  • Accessibility
    We would like to coordinate the ongoing accessibility efforts in the opencast community and discuss options to additional evaluation and development efforts.
  • Workflow Configuration in JSON
    Currently, the workflow configuration panels are defined in HTML in the workflow definition files. These HTML definitions cannot be displayed and parsed correctly by the new implementation of the admin-UI. That’s why, we propose a JSON definition of these configuration panels to simplify the parsing and displaying in React.js. In this workshop we aim to define a concept for these configuration options.
  • Integration of Opencast in Moodle
    In this workshop, I’ll show how to configure Opencast and Moodle for a seamless integration. In the demonstration the newest features will also be presented. After the presentation, we will have time to discuss the usability of the Moodle plugins and the roadmap for future development.
  • Integration of Opencast in ILIAS
    In this workshop, I’ll show how to configure Opencast and ILIAS for a seamless integration. In the demonstration the newest features will also be presented. After the presentation, we will have time to discuss the usability of the ILIAS plugin and the roadmap for future development.
  • Opencast Annotation Tool – A common way forward
    In this workshop I would like to discuss a common way forward for all parties interested in using the Opencast Annotation Tool (OAT). Discussion points would be:
    What is the current state of the OAT?
    What needs to be done to get the OAT to a stable state usable by everyone?
    Which feature request are of interest to multiple parties?
    How can we coordinate future work on this tool?

Opencast Summit 2022: Call for Proposals

The Opencast Summit (March 8th – 10th, 2022) is dedicated to the use and management of educational videos with Opencast. While the focus of the event will be on Opencast, the community seeks participation from related domains and projects.

We are therefore inviting educational designers, service providers and others working with video in academic settings to share expertise and experience across the field and explore opportunities to collaborate in related projects.


The conference committee is looking for proposals in the following tracks:

  • Opencast adopters
    • Experience in using Opencast for lecture capture/video management
    • Ideas for new features in Opencast
    • Solutions to further develop Opencast
    • Integration scenarios
  • Opencast developers
    • Presentations and meetings with a focus on technical details, likely to  see developers, system administrators, A/V-technicians and those interested in issues related to these domains.

Proposal types

There are different types of proposals for these tracks:

  • Lightning talk: 10 minutes, including 5 minutes Q&A
  • Presentation: 30 minutes, including 5-10 minutes Q&A
  • Birds of a feather (BoF): 1 hour. Suggest a topic you would like to discuss with others.
  • Workshop: Bring forward a topic you would like to introduce others to or discuss with others. Workshops should happen in the two weeks after the conference. Feel free to also propose a workshop topic you would like to attend.

Alternatively, feel free to suggest a workshop for a topic  you would like to know more about. Ideally, you can designate/suggest  someone to host, but feel free to make this a task for the program committee.


Please submit an abstract of your proposed presentation and the format you would like via the provided registration form by 22 February 2022.

Opencast Summit 2022: Save The Date

The Opencast Summit 2022 will take place from March 8-10, 2022. Due to the current situation, the Summit will take place online. The event will be hosted by Osnabrück University.

Sessions will start at 12pm UTC every day and end at about 4pm UTC, depending on how many sessions will be submitted.

We invite newcomers a day early to an Introduction to Opencast workshop at 12pm UTC on March 7, 2022.

Following the Summit, there will be a number of workshops to take an in-depth look at some topics of particular interest to the community. Workshops can be submitted by anyone. If you are interested in a topic but cannot host it yourself, you can also request a workshop. At the Summit a planning session will be held during which the workshop hosts shortly present what their workshop is about, and we can decide when to schedule the workshop.

There will be another post shorty with the call for proposals.

The conference schedule is live:

Opencast Summit 2022

New Opencast summit schedule

As a result of the Opencast Summit 2020 the board started to evaluate if the current schedule and format of the Opencast Summits still fits the adopters’ needs. As part of that a survey was conducted. Based on results and on further discussions in the community schedule and format of the Opencast Summits have been adjusted.

The need schedule is:

  • Opencast Summit, an international conference at the end of March, three days in person. For the community to meet and talk, sit together, work together, discuss things. Plus, there will be workshops and hackathons. As little talks as we can.
  • DACH Meeting of the German-speaking community, end of August, 2 days in person. Same as the Opencast summit. Aber auf Deutsch.
  • Opencast Online Summit, beginning of December, three or four half-days. Talks, talks, talks. And a few other formats that work online.

We will start with the new schedule in 2022. So the next event for the Opencast community will be the Opencast Summit in March 2022. However, based on the further development of the pandemic, it has yet to be decided if the Summit can take place in person, or will take place online again.

Opencast Summit 2021 Survey Summary

The Opencast Summit 2021 was the first International Opencast Summit that took place entirely online. This resulted in a huge increase in the number of participants. While previous summits were attended by about 80 participants (in person) the 2021 Summit was attended by 170 participants via web conferencing.

In order to better understand why so many participants attended the Summit and what could be improved for future meetings, a short survey was send to all Summit participants. This survey was filled out by 22 participants, 8 of these attended the Summit for the first time.

Overall the participants were satisfied with the Summit and were glad it took place at all. Accessing the talks via BigBlueButton and attending online seems to have worked well. New participants pointed out that they liked the variety and range of topics in the presentations. However, the “conference feeling” was missed by many. Being able to talk to people one on one during breaks was missed.

Of the 22 participants who filled out the survey, 14 would have been able to attend the Summit in person, if in person attendance had been possible. For 8 that would not have been the case. Of these 8, 4 attended the Summit for the first time. Some of the participants (7) furthermore stated that they would prefer to meet online for future Summits while 15 would like to meet in person if that’s possible.

For future Summits the Board thus has to consider that while many people in the community would like to attend a Summit in person, there is a considerable number of people who would like to or are only able to participant online. This poses a challenge for future Summits and raises the question of how future Summits should be organized. While this question has been not been answered, the Opencast Board is working on a concept for a way forward that addresses this challenge.

Opencast 10

Opencast 10 has been released. The release notes can be found in the administration guide documentation. Important changes in this release are:

  • A new workflow operation handler has been added: conditional-config. This workflow operation handler can used to evaluate a list of conditions and set a workflow configuration variable accordingly.
  • JVM metrics have been added to the metrics endpoint. This way Opencast’s memory and CPU behavior can be monitored more closely using Prometheus.
  • Opencast Studio, Elasticsearch and many libraries across the project have been updated.

2021 Apereo Fellows

The Apereo Foundation announced the Apereo Fellows for 2021. We are happy that one of the chosen Fellows is from the Opencast community.

Maxilmiliano Lira Del Canto has been announced as a Apereo Fellow.
