Want to showcase your team's performance with wrestling-specific, professional looking, automated scoring graphics? Here's an example.
Takedown Scoring and Stats automatically generates five scoring graphics:
- Match clock
- Match score with wrestler names and weight class
- Riding time (college)
- Team score (dual meet only)
- Team summary
These graphics are sent over the WiFi network and available to any video production system on the same network. Because the graphics are network-delivered, your scoring iPad and video production system can be independently located in your venue.
With this feature, a team can produce professional quality video just by virtue of scoring matches with Takedown.
In settings, turn on Scoring Video Overlay. Enable any or both of the additional options.

COnfiguring your video Production System
The Takedown scoring graphics are transmitted over Wifi as NDI Sources. NDI is a technology for sending video objects over a network. In this tutorial, we use the open-source and free Open Broadcaster Software (OBS) Studio along with the NDI Plug-in on a Windows 10 computer.

This is an example of the OBS video output using Takedown Scoring Graphics with an actual college match (Boyd v. Dean, Dec 2016). With OBS you can direct your video to a live streaming site, like Youtube Live, or to a file for uploading at a later time.

- Confirm OBS Studio is installed
- OBS: download the NDI Plug-In and install
- OBS: after installing NDI Plug-In, restart your PC
- OBS: import this Scene Collection. Adjust as necessary
- Confirm your Takedown iPad and your PC are on the same Wifi network
- On your PC, change your Network profile to Private
- On your PC, change any security software to allow incoming connections
- On your PC, change any security software to enable "discoverability"
- Diagram of how the scoring graphics work
- Bits and bytes
- The scoring graphics require about 100 kbps of network bandwidth
- Takedown and your video production system must be on the same IP subnet. NDI doesn't work reliably across different subnets.
- If using a PC-based video production system, the Windows firewall must be configured to allow reception of the NDI stream. Configure your PC to use the "Private" Network Category for best results. Your PC must be "discoverable."
- More on underlying NDI protocols here and here.
- Use the NDI Tools to verify whether your PC is can receive NDI streams. NDI Monitor and NDI Test Patterns are especially helpful in diagnosing network issues.
- Since NDI is network-based, you can have multiple video production systems sourcing the same Takedown Scoring graphics.
- NDI Video Data Flow here.
- Open Broadcaster Software (OBS) Studio
- This is the same software recommended by Trackwrestling for Trackcast.
- We've tested OBS Studio on a 64-bit Windows 10 PC with a multi-core Intel processor (i5-2400 @ 3.10 Ghz) and 8 gigabytes RAM. Although the Takedown scoring graphics aren't network or CPU intensive, video production is. Use the most powerful PC you can wrangle.
- Embedded Intel graphics processors might not have the horsepower to render the video in a timely manner. If possible, use a dedicated graphics processor.
- OBS with the NDI plug-in isn't reliable on an Apple computer and we don't recommend this configuration at this time.
- The OBS NDI plug-in isis updated every few weeks. Check for latest version.
- After installing the OBS NDI plug-in, restart your PC. Not doing so will cause grief.
- After configuring Takedown Scenes in OBS, save your Profile and Scene collections. so you won't need to reposition and resize all of the scoring graphics again.
- Live Streaming
- Check out the OBS streaming options! YouTube Live, Twitch, etc.
- You'll need at least 2 Mbps of upstream network bandwidth to get good quality
- Enable "Start Recording" during streaming if your PC has the horsepower to do both. If the streaming gets flakey (or fails) then you'll have a copy of the video on your hard disk drive for uploading to your preferred cloud location later.
