eSports Slow Motion and Instant Replay

Written by on July 21, 2019

Join us for another battle royal in slow motion, instant replay. Today we demonstrate a great workflow for setting up the high frame rate and high bitrate live streams for sports. Today we use a live ping-pong match to demonstrate a 4 camera instant replay system with 60 frames per second recordings at 100 Mbps. With four cameras all recording in 1080p at 60 fps we are able to use four cameras for instant replays during our live production. We also have 8 cameras in our production for use during our live sports broadcast.

 

The entire broadcast includes ceiling-mounted PTZOptics 20X-SDI cameras, along with PTZOptics ZCams and vMix. Using the vMix instant replay system we are controlling everything with an xKeys jogdial and T-bar system designed for live instant replay. Then the entire production is streaming in 1080p at 60fps using 6 Mbps. This high bitrate stream is the re-distributed or “restreamed” to LinkedIn, Facebook, YouTube, Twitch and Periscope (Twitter).

In this way, we can use EasyLive to transcode our high bitrate live stream and effectively reach 5 content delivery networks. Check out this entire live stream and enjoy the post-show podcast where our hosts break down some of the events we have planned for this summer. We also break down the technology we are using for live streaming this ping pong match. Did you see our broadcast last week? We did a little eSports live stream using Rock Em Sock Em toys. Check out our vMix Slow-Mo Instant Replay and X-keys XKE-64 Replay unit review here.

 

Finally, we should mention the use of the Newtek NDI to bring in our scoreboard. With so much going on inside our main video production software system, we have found it nice to use the NewTek NDI over our local area network to bring in video from another laptop. In this example, we have a scoreboard that is being updated by another machine on our local area network and that video output can be brought into our main vMix production using an NDI input source. In this way, we can increase our production capabilities and have more people working on the same production. We briefly referenced the way our scoreboards have been set up in this live show and the last. If you have any questions let us know in the comments below.
