Preparar a sessão

    • Entrar no Videocast com SSO
    • Criar a sessão (título, data/hora, opções de acesso, elementos de página).
    • Personalizar o layout (vídeo + slides, chat, redes sociais) conforme o tipo de evento.

Configurar o encoder

    • Abrir o OBS (ou outro encoder).
    • Selecionar fontes (câmara, microfone, partilha de ecrã).
    • Inserir as credenciais/URL fornecidas pela sessão Videocast. 

Testar e emitir

    • Teste privado: verificar o áudio (níveis), vídeo (framerate, iluminação) e latência. Clique Iniciar transmissão no encoder.
    • A página da sessão exibirá a emissão em HTML5 com compatibilidade móvel.

Acompanhar e encerrar

    • Use o painel do Videocast para monitorizar audiência e estatísticas, e moderar chat (se ativo).
    • No fim, pare a emissão no encoder e feche a sessão.
    • Streaming encoder (e.g., OBS Studio, Wirecast) to generate the video/audio stream from your camera/desktop.
    • A stable network connection with sufficient bandwidth for the broadcast bitrate (avoid using Wi-Fi during production).
    • Audiovisual equipment (camera, microphone, slide capture) and a designated operator.

4. Creating and Broadcasting an Event

Prepare the session

    • Log in to Videocast with SSO.
    • Create the session (title, date/time, access options, page elements).
    • Customize the layout (video + slides, chat, social media) according to the event type.

Set up the encoder

    • Open OBS (or another encoder).

    • Select sources (camera, microphone, screen sharing).

    • Enter the credentials/URL provided by the Videocast session.

Test and Broadcast

    • Private test: Check the audio (levels), video (frame rate, lighting), and latency. Click Start Broadcast in the encoder.

    • The session page will display the broadcast in HTML5 with mobile compatibility.

Monitor and end

    • Use the Videocast dashboard to monitor audience and statistics, and moderate the chat (if enabled).

    • When finished, stop the stream in the encoder and close the session.

5. Integrations and Recorded Content

    • The broadcast page allows sharing on social media and embedding (iFrame/Widget) on institutional websites.
    • To manage recorded videos and distribute them to classes, use Educast (an FCCN service focused on recording and post-processing classes).

6. Best Practices for Production

    • Audio first: use a dedicated microphone (lapel/shotgun) and test the levels.
    • Lighting: avoid backlighting and mixed color temperatures.
    • Readable slides: font size ≥ 24 pt, sufficient contrast (WCAG AA), and no excessive text.
    • Network: Prefer Ethernet and reserve bandwidth for the broadcast.
    • Plan B: Have a local recording in OBS and a 4G/5G hotspot as a backup.

7. Accessibility and Compliance

    • Subtitles/Transcripts: For recorded events, provide a subtitled version; for live events, consider using human support for real-time captioning (when necessary).
    • Contrast and minimum font sizes for graphics and overlays (follow WCAG 2.1 AA).
    • Clear language and language identification in materials (PT/EN), maintaining consistency with the EN version of the website.
