My church live streams their Sunday and Wednesday services to Youtube, currently we are uising a logitech usb webcam, the video isn't the greatest. We want to upgrade to an HD camcorder without spending a bunch of money. The computer that we are using currently has a firewire capture card in it. We are using OBS Studio to render the livestreams to Youtube. So the camera needs to have firewire output, and be compatible with OBS Studio. Thanks

Many of the newer cams today have 4k. You might want to look at a GoPro. If you need zoom features and high quality you can use a DSLR for video as well as serve the church for documenting functions.
