# Preparing assets for airing # General operation When Brainsonic Live provides airing operation services, our operators will be in charge of - Playback intro/transition/outro animations and music - Collecting live streams and communicate with third party stream provider - Collecting and playback pre-recorded video files - Adding appropriate graphical overlays (watermarks, lower thirds) - Airing to appropriate destinations These operation are handled from our Parisian Airing Operation Center (AOC)
--- # Pre-recorded assets ### Content You may consider two scenarios: 1. You produce a content ready to be aired 2. Brainsonic Live integrates your assets into a master program ##### You produce a content ready to be aired In this case we expect video files, respecting the format that are ready to play. This should not contain pre not post video loops as explained in the page [Program schedule](https://docs.streamaura.net/books/guide-for-third-parties-content-providers/page/program-schedule "Program schedule"). ##### Brainsonic Live integrates your assets into a master program Brainsonic Live might send you graphic assets to use during post-production, that might includes: - Customizable lower third template in a convenient format ([.mogtr files Adobe CC compatible](https://helpx.adobe.com/premiere-pro/using/motion-graphics-templates.html)) - Backgound slate for multi frame or PiP compositions

Your video should not contain any intro, outro animation nor general watermark (i.e. event logo) as those will be added downstream by Brainsonic Live.

### Format Our operators are expecting two file exports: - A full edit that includes lower thirds - A clean edit that does not include lower third. We might have to use this and add lower thirds ourselves in case of a sudden change in frame organisation. {{@11#bkmrk-container-mp4-file-e}} ### Delivery timeline - We recommend third parties to provide their asset a week before the event. - In case of an unpredictable change, the final version pre-recorded files need to be provided within a minimum of 4 days before airing. # Live sources ##### Content Brainsonic Live might send you graphic assets to use during production, that might includes: - Backgound slate for multi frame or PiP compositions - Full frame video animations including audio that intend to be played for physical audience ##### Protocol Our operators are expecting a single stream sent to two different ingest endpoints (main/primary and backup/secondary) The protocol we accept is SRT1. SRT is compatible with a majority of encoding software and hardware like [VMix](https://www.vmix.com/help23/index.htm?SRT.html), [OBS](https://obsproject.com/kb/srt-protocol-streaming-guide#:~:text=Stream%20with%20SRT,-Go%20to%20Settings&text=In%20the%20Service%20dropdown%2C%20select,enter%20anything%20for%20the%20key.) or [Tricaster](https://support.newtek.com/hc/en-us/article_attachments/1260802200430). Brainsonic Live provides two local (closest datacenters) SRT, of type `srt-listener`, ingest points IPs. Those ingest points are reachable though port `10 000`. A monitoring output (loop out of what you send on port `10 000`) is provided as well. The final program output can be provided though SRT upon request. *1 In some rare cases SRT cannot be used at event location. Even if we do not recommend it, we can accept RTMP ingest following the same encoding specifications.* ##### Encoding {{@250#bkmrk-container-mp4-file-e}} # Médias pré-enregistrés ### Contenu Vous pouvez envisager deux scénarios : - Vous produisez un contenu prêt à être diffusé - Brainsonic Live intègre vos ressources dans un programme maître. ##### Vous produisez un contenu prêt à être diffusé Dans ce cas, nous attendons des fichiers vidéo, respectant le format, qui sont prêts à être lus. Ce contenu ne doit pas contenir de boucles vidéo pre et post comme expliqué dans la page Grille de programmes. ##### Brainsonic Live intègre vos ressources dans un programme maître Brainsonic Live peut vous envoyer des ressources graphiques à utiliser lors de la post-production : - Un modèle de tiers inférieur personnalisable dans un format pratique (fichiers[ .mogtr compatibles Adobe CC](https://helpx.adobe.com/premiere-pro/using/motion-graphics-templates.html)) - Une image de fond pour les compositions multi-images ou PiP

Votre vidéo ne doit pas contenir d'animation d'intro ou d'outro, ni de filigrane général (par exemple le logo de l'événement), car ceux-ci seront ajoutés en aval par Brainsonic Live.

### Format Nos opérateurs attendent deux exportations de fichiers : - Un montage complet incluant les tiers inférieurs - Un montage propre qui n'inclut pas les tiers inférieurs. Nous pourrions être amenés à utiliser ce dernier et à ajouter nous-mêmes les tiers inférieurs en cas de changement soudain dans l'organisation du cadre. {{@11#bkmrk-container-mp4-file-e}} ### Délai de livraison - Nous recommandons aux tiers de fournir leur matériel une semaine avant l'événement. - En cas de changement imprévisible, les fichiers préenregistrés de la version finale doivent être fournis au minimum 4 jours avant la diffusion.
