The word “Go” has so many connotations for such a couple of letters. It’s typically upbeat & positive, forward-looking and action-oriented. You get £200 for breezing past it in Monopoly, it’s the oldest board game known, it’s a popular open-source programming language and it’s what the Thunderbirds do.
Back in April 2021, ToW #574 talked about sharing a countdown timer in Teams, if you want to make it clear in a meeting that it’s about to get underway. That was by sharing the application window of a countdown clock, meaning that it would replace any other desktop sharing/slides etc being shown.
Also, the timer will loom very large on the screen of everyone watching, which could well be effective though maybe lacking some of the subtlety you’d prefer.
A more nuanced tip would be to overlay a timer on your own video feed, so you could make the point that things are about to change, and it could be shown alongside other content or whatever else might be happening in the meeting.
Depending on how you do it, the timer could disappear altogether when it has finished, and you’d carry on with the video as before. You might even want to replace your own camera feed with a backdrop and timer until you’re ready to go and show your face.
One recommended way to achieve this effect is to use OBS Studio, open source software which started life as a kind of video manipulation tool aimed at recording or streaming, and has grown to offer a host of features and plugins to modify and manipulate video in real time. It can look a bit scary to start with, but the basics can be picked up quickly.
OBS Studio can apply a series of effects to one or more video sources – could be the real-time recording of windows showing a live demo or a physical camera, with some other stuff like a video file, overlaid on top. You can go down a rabbit-hole of effects (like put a real-life green screen behind you, then chroma key a backdrop or video onto your own video feed – see Scott Hanselman’s tutorial for inspiration).
OBS also includes a virtual camera driver, so while you’re running the software and combining several sources – like a real camera and one or more media sources overlaid on top (along with selected effects) – OBS will combine everything to look like it’s a camera feed that can be selected in Teams, Zoom or any other software that could use a video input.
A simple trick could be to add only a countdown video to OBS and then choose the OBS Virtual Camera in Teams; it will display the video instead of your camera feed, and then when you’re ready to get going, just change the video settings in Teams to go back to your own webcam.
There are plenty of sources online for free countdown videos – here or here for example; download the file, add it to OBS as a Media Source and you’re off. If you’d like to take it up a level, here’s a more in-depth tutorial, and you can even script your own custom ones if you like to delver deeper into OBS features.
