Meeting

Powerpoint has numerous issues and presenting video is one of them. If you are just presenting slides without fancy transitions consider using OBS Studio, which is a very stable and free product that can do slides, images, handle multiple videos, video capture devices, screen capture, window capture, multiple audio sources, cameras, NDI sources, text, browser display and has the capability to include numerous plugins for additional functionality. It can output to multiple screens simultaneously and is easily screen shared with Zoom or used like a webcam and can record all the output in HD to a file.
