capture video

hi

Is there a way or 3rd party open source library that I can use to capture the gameplay in monogame to a video?

Just use normal screen capture software for your os, does not need anything special from MonoGame.

Unless you want to capture graphics Stas for development, in which case use the tool for that shader pipeline, most likely pix or render doc for directx

Yeah, using regular screen capture software should be enough for recording gameplay in MonoGame. If you need to capture the graphics for debugging, PIX or RenderDoc could be useful too.
