 === Help === Help
  
-We need help(ers) (/volunteers?) to run our setup in each room, mainly to operate cameras but also to operate the video mixer for switching between camera and slides. The organiser is responsible for making these helpers available. See also [[HelperIntroduction | Helfereinführung]]+We need help(ers) (/volunteers?) to run our setup in each room, mainly to operate cameras but also to operate the video mixer for switching between camera and slides.

 === AV === AV
-* Audio: we need a Mono audio mix per XLR, which we insert into a camera directly. +* The location must have some sort of PA system. Our audio equipment does use XLR outputs, but we do bring adaptors to be able Cinch (RCA) and 3.5mm Mini-Jack if needed. 
-* We also own audio equipment (mixer, microphones), which we don't always bring with us. When our equipment is absolutely necessary, clarify this as soon as possible with us. +* The location must have some sort of video display. This is usually a projector, but having a large screen also works. Our equipment produces a 1080p ("FullHD") signal via HDMI or SDI. If your display does not support that, please get in contact with us, we have a stockpile of adaptors which we can bring if needed. 
-* We *do not* own a PA system, this will have to be provided by the location or rented externally. Please clarify this as early as possible. +
-* Slides, projector signal via HDMI preferred, VGA as a backup. 19:9 aspect ratio is required. +
-* Projektor/Folien: Projektor-Signal per VGA oder HDMI – bevorzugt in 16:9. Please clarify where we can split the video signal into our system.+
  
 === Schedule/Program === Schedule/Program
  
-Our semi-automated editing platform needs the program/schedule in the schedule.xml format. When you are not using Pretalx, we can import spreadsheet files (CSV, ODS, XSLX, Google Docs, etc) or you can build your own tooling. For more information see [[schedule]].+Our semi-automated editing platform needs the program/schedule in schedule.xml format. These file are produced by the usual conference planning solutions (frab, pretalx, ...) without needing to configure anything. If you want to use pretalx, but don't have the means to run your own instance, you can use [[https://pretalx.c3voc.de|the c3voc pretalx instance]] or [[https://pretalx.com|pretalx hosted]].
  
-As of 2022 you can now also use our [[https://pretalx.c3voc.de|own Pretalx intance]].+If you don't use any of these tools, we do have some tooling to import spreadsheet files (CSV, ODS, XSLX, Google Docs, ...). See [[schedule]] for more details. Of course, building it using your own tools is fine as long as it conforms to the published XSD.
  
  
 === Network === Network
  
-Our system more or less requires access to the Internet. If a firewall is on site, we need free access to the listed ports at various (often changing) addresses on the Internet, unfiltered access is much preferred. Access should also be *without* a browser based portal. +For our systems to work correctly, a wired internet connection is required. We do require IPv4 connectivity, but a NATed connection is fine.
-* **TCP:** 22 (SSH), 80 (HTTP), 443 (HTTPS), 6667 (IRC), 6697 (IRC), 1883 (Mosquitto), 8883 (Mosquitto) +
-* **UDP:** 53 (DNS), 1194 (VPN)+
  
-When sufficient Upload bandwidth is available we can also offer live streaming. We need at least 3MBit/s per stream/room, 5MBit/s is better.+Due to the nature of the infrastructure, we cannot provide you with a list of ip addresses we need to connect to. If your network does have restrictions, please ensure we can reach the whole internet on these ports: 
 + * **TCP:** 22 (SSH), 80 (HTTP), 443 (HTTPS), 6667 (IRC), 6697 (IRC), 1883 (Mosquitto), 8883 (Mosquitto) 
 + * **UDP:** 53 (DNS), 1194 (VPN), 20000-20255 (VPN) 
 + * **Optional, additionally for Users:** TCP 143, 587, 993 (Mail), UDP 13337 (VPN), 60000-60100 (Mosh) 
 + 
 +For streaming to work reliably, an uplink bandwidth of atleast 5mbit/s per room is required. 
 + 
 +If we do put hardware into more than one room (or if we have a separate office for post-processing), it would be very beneficial to have all the rooms connected to a separate layer 2 segment (separate VLAN is sufficient). We will bring our own router hardware, please do not put a DHCP server in there.
  
-At events with more than one room we need all presentation rooms and our own office room connected to the same Layer 2 segment (for instance our own VLAN). Each room should have free Ethernet port(s), WiFi is insufficient. In an "emergency" we can run cabling through open windows or under doors etc. 
  
 === Design === Design
  
-We produce videos in Full HD, meaning 1920x1080p25. This means that we require artwork in these formats: +We produce videos in FullHD (1920x1080, 25fps).
-* Background image as PNG, optionally as an animation.  +
-  * See the background of [[https://cloud.githubusercontent.com/assets/40266/24840604/3ab09c48-1d70-11e7-98e6-569970d152d2.png|1]] - there are several possible use cases for the background, see this video https://youtu.be/DNMpEpZnPLk?t=24m16s for possible limitations. +

-  * Optionally include "streaming logos" with room names +
-    * Example https://github.com/voc/intro-outro-generator/blob/master/fossgis17/artwork/overlay.svg +
-  * Optionally Artwork/design for the live streaming website +
-    * Logo, CSS see https://streaming.media.ccc.de/fossgis17/ and https://github.com/voc/streaming-website/blob/master/README.md#konfiguration +
-  * Optionally an [[https://info-beamer.com/|Infobeamer]] design+
  
 +You should supply us with the following artwork files:
 +
 +* Background image as PNG, optionally as an animation.
 +* **Intro:** This should be either a static PNG or some sort of video which we can use in our generator to create intros. Optionally you can provide us with fully rendered videos for each event/talk that we should provide videos for.
 +* **Outro:** Same as Intro. We can use event/talk-specific intros, but usually we use one conference-wide outro.
 +* When live streaming:
 +  * **Break animation:** A looping video that informs the viewers that there's currently no stream running.
 +    * Example: https://github.com/voc/intro-outro-generator/blob/master/sotmeu14/examples/pause.mp4?raw=true
 +  * **Break music:** Music that is playing while the break animation is playing. **Must** be royality-free (ideally CC-BY or CC-0)
 +  * **design for the live streaming website:** Logo, CSS see https://streaming.media.ccc.de/fossgis17/ and https://github.com/voc/streaming-website/blob/master/README.md#konfiguration
 +* Some design files for [[https://info-beamer.com/|info-beamer]] so we can show pretty animations on the projection screens while no talk is running.

 === Insurance === Insurance
  
-The organiser has to insure our hardware for damages and theft during the event and relevant transportation from/to the event. Since the hardware is relatively expensive (ca. 10kEURO / room) this is usually handled by an event insurance which most organiser will already have. When necessary we can supply relevant serial numbers upon request. See [[eventhowto#anlieferung_versicherung]] for more information on this topic.+The organiser has to insure our hardware for damages and theft during the event and relevant transportation from/to the event.
