Instant Replay with VMIX

by Luke Eclipse-Ujano Updated on

This may not be the $20,000 instant replay system we want, but it's the one we have.. and it works.

Set Up Web Presenter

SDI IN: AUX on the Big Black Box
USB C: USB C on Instant Replay Computer

AUX on the Big Black Box is OUTPUT 2 on the Constellation. To change camera angle, use the ATEM Control Software on KVIKS-MOBILE-3.

Output Signal to Big Black Box

This is how the instant replay on VMIX sends to the live stream equipment.

HDMI from Computer to HDMI to SDI Microconverter
SDI OUT from HDMI to SDI Microconverter to CAM8 on the Big Black Box

Audio Follows Video

On the ATEM Control Panel, go to Audio, then XXX, check that AFV is enabled. This will ensure that if the music track is enabled on a highlight reel or event playback, it will automatically play when faded to it.

Setting Up Stinger Transition on ATEM


If your VMIX window looks brand spanking new, then click on the arrow next to Open, then VMIX Instant Replay. If it's not there, press Open and look for the preset in the Documents folder.

Clip Organization

Tagging a Clip

To tag a clip, right click near the right side of the white square and either type in or select a tag.

Clip Folders

The tabs labeled 1 through 20 are folders you can use to keep organized. Ideally, you would want to utilize one folder per quarter, then at the end of a quarter, copy over the best shots to another folder as a highlight reel.
