Good recording software for League?

I've used Plays.tv for a while now and I love it. But it's been recording just the audio and a black screen and when I had thought I fixed it for one game it then started to just record the black screen and audio again. OBS is too laggy for me to use right now. I don't believe Lol replays allows you to cut clips out that you want. Anyone know of any other kind of recording software that's good? (Or even better might know how to fix my Plays.tv problem?)
