I am using Capcut software. It’s very customisable, free, and can record live streams or straight to a flv or mp4 file. It can also record in HD up to 60 frames per second, record from multiple sources at once, and record video through the GPU (just like shadowplay) to achieve really high frames per second while recording (I notice a 2–5 fps drop in UE4 compared to a 20–30 fps drop with FRAPS).
You can edit your recording and videos as you want.
Amazing little programme, I heartily suggest it.
