SAP Inside Tracks have become a worldwide phenomenon, with 40+ events in 2019. There is a continuous stream of high quality content presented nearly each weekend during the year. Still only very few people are able to see it, because most SIT organisers don't stream and record the sessions during the event.
Already in 2015 the SAP Inside Track Munich was streamed live and recorded on YouTube. Another pioneer for the live streaming of an SAP community event was Tobias Hofmann who wrote this post: SIT BR STREAMING – HOW IT WORKS already in September 2017. The SAP Inside Track Munich and SAP Inside Track Berlin 2017 also streamed live using YouTube that same year. The SAP Inside Track Munich 2018, SAP Inside Track Barcelona 2018, SAP Inside Track Vienna 2018 and SAP Inside Track Berlin 2018 where recorded that way. At the SAP Inside Track RuhrPOTT 2019 Oliver Kohl presented Live Streaming SAP Inside Tracks which is the reason to start this page.
The goal of this guide is to enable SIT organisers to live stream sessions on any of the popular streaming services (YouTube, Twitch, etc.), while recording the content for post production and publishing. It documents technical setups with increasing complexity, costs and efforts and that are able to produce good or very good video content.
This is a living document, and you are invited to contribute to it.
There is a Slack channel available for SIT organisers to share their experience with streaming and recording SIT sessions. Join the SAP Mentors Slack and there the #opensit channel to contribute or ask any questions on this topic.
Keep in mind: session streaming and recording is not mandatory at a SIT, and every organiser can add his/her own flavor on how to run a SIT. Your primary goal should be to provide a stellar onsite experience for all participants. But if you dare to try streaming/recording, we are here to help
Some hardware equipment and software that the setups require...
No surprise here - capture the audio and video, record it to disk. Mac or Windows should work and has been tested in the wild. No experience with Linux yet.
OBS Studio (Open Broadcaster Software)
This Software for video recording and live streaming provides all capabilities for creating professional productions, is Open Source, and highly extensible via plugins, and has a broad community of supporters. Its sole purpose is to capture multiple audio and video streams, compose them into a single video stream defined in a set of scenes, which can be used for real-time direction of the production.
There is a large number of beginner and advanced tutorials available:
- How to Use OBS Studio (Beginners Guide)
- How To Record With OBS!
- Getting Started with Open Broadcaster Software OBS
- Scenes in OBS Studio
Camera & microphone
There is a huge variation possible, starting from regular (ICON)mobile phones, to (ICON)high end cameras with multiple wireless microphones. The quality of the production result is mainly defined by what is going to be used in this area.
This is the most basic variant. A mobile phone or any web cam functions as camera and mic, often connected via USB or Thunderbolt. Already here it is recommended to have an image overlay with the SIT logo, speaker name & session title, which can be defined in OBS as single scene.
- Easy to setup
- Slides might become hard to read
- Audio probably not very good
iPhone App: Camera for OBS Studio
Android App: N/A?
In this setup we are add the speaker laptop as additional video source to capture the presentation slides. We now have two video stream as input, which requires more advanced scene composing. The video output of the speaker laptop needs to be converted into a consumable input stream for OBS. The UltraStudio Mini Recorder by Black Magic is a solid option for this.
Instead of connecting the presenter PC directly to the Projector or TV it is connected to an HDMI splitter that then connects to the Projector/TV. So the interface for the presenter doesn't change. You might need adapters from Displayport and VGA to HDMI for older computers. Please check this before the Event. From the HDMI Splitter the signal goes into the Blackmagic Ultrastudio Mini Recorder which has a Thunderbolt output. For a good audio quality the Audio Interface should be connected to the mixer of the speaker / audience microphone. The camera might be a simple Webcam which is connected via USB or an action cam like the Gopro Hero4 that has a HDMI output that can be connected via an additional Ultrastudio Mini Recorder.
- Easy to read speaker slides
- Audio probably not very good
- One time invest into video converter

Semi Professional Setup
We can significantly improve the audio quality by adding a dedicated speaker microphone. Wireless mics are ideal to give the speaker freedom of movement. A professional broadcast camera will be used to record the speaker. This type of professional equipment can be rented, but often isn't cheap. A dedicated sponsor just for the streaming setup might help here.
- Excellent speaker audio and video
- Renting the camera, mics and mixer can be pricey
Broadcast cameras: SONY PMW-200
Speaker microphone: Sennheiser 200 Series Wireless Mic
