You don't actually need a capture card to record PS4 games. The PS4 has a Share feature which lets you record,and theres an app called Sharefactory which lets you edit and render your videos. It's nothing special, but I use it for my videos.
Currently I'm doing:
Batman Arkham Knight
Minecraft (Called Aiden Plays Minecraft)
Terraria (Called Terrarian Journey)
Don't Starve
I have other games i started a series of but they weren't popular.
If enough people request them tho, I'll bring them back.
