How to record a freedoom video

[Valerio]

Hello,

 

I tried to record a video of my freedoom game, using VLC, but it didn't work. On the video, all I could see was a black screen with the small window of gzdoom (you can see it on the screenshot below). Does anyone know how to do it properly, or can you suggest another software to do it (for Windows 10)? Thank you very much !

You can use geforce experience, i use it for my videos and it's really good, but vids recorded with that have a really big file size, for example: a 2 minute video is 598 mb.
