There are tons of OBS plugins that are out there. Here are all that ones I use to make my live streams run smoothly
This is by far the best open/closed caption option I have found for OBS. I have this placed below my camera scenes and when using it with Move Transition it will just follow where ever my camera goes.
Closed Captioning via Google Speech Recognition 0.0.8
I use this around all my camera sizes to create a nice rounded corner and a blur effect around my camera.
Advanced Masks
Sometime I like to record just my gameplay scene in the background so I have a back up an option without overlays. This gives some more flexibility to edits.
Source Record
I use this to copy my main camera source so that I can resize, add effects and filters all without messing up my main camera.
Source Copy
I use this in conjunction with Elgato StreamDeck to easily move my camera around with a click of a button or automate with MixItUp.
Move Transition
I use this on my Starting Soon scene while music/game music is playing. Gives a nice little added visual.
