ScreenStudio: Testing transitions
February 2 2017
After adding transition when a source would start, I have managed to support also transitions when the video source stops. It even works when the whole recording stops as ScreenStudio will delay for around 2 seconds the end recording time to have the time to execute the OUT transitions. This means that you can now have an ending to your streams or recording showing anything you want.
