01. Hybrid event

We participated in the new edition of the annual meeting of Celsa Group, this time in a hybrid format.

The 2021 edition was 100% online details here. This year Celsa Group wanted to make the meeting in a hybrid format.

Three physical locations: Barcelona, Bilbao and Santander, connected live between them through our WeCongress system. Thanks to this, all the speakers and attendees were able to interact with each other as if they were in the same room.

A technological test that was a great challenge for us and that we were able to carry out without any problems.

At the same time, a microsite was opened so that the event could be seen from the different floors. In this way, more than 1,300 professionals from Celsa Spain Group and Global Support&Services could follow and participate in the presentations, the awards ceremony, Q&A and speeches from the authorities.

02. Audiovisual production

Three locations with four different realisations

During the event, live broadcasts were carried out from each of the three locations where the event took place.

A fourth was added to these three realisations for the virtual version of the event. In this way, we allowed a large part of the Celsa Group team to be part of the meta-event without travelling to any of the theatres where the live shows took place.


03. Microsite

A microsite was created with the live streaming of the event so that people from the Celsa Group plants could attend the event virtually.

04. Presentation Video

Celsa Portal Presentation

Within the Annual Meeting 2023 framework, we created a presentation video showcasing the most useful tools offered by the Celsa portal for Celsa Group employees.

The video was screened during the breaks of the 2023 Annual Meeting, but it will also be used for playback on the informational screens located in Celsa Group offices and plants throughout the year.

05. GR40 Crane Video

Presentation of the GR40 crane automation project

At Celsa Group, they have been working on automating the GR40 crane for moving billets for some time.

For their innovation feature in May 2023, we created a promotional video to showcase this project and its implementation plan for other group plants.

In this case, we deployed cameras and drones to obtain the necessary footage for the video's narrative. We also conducted interviews with the people involved in the project, with them creating the storyline for the audiovisual.
