Record video with sound in Action

[exaltedthrift]

Can you tell me if it is possible to record video with sound in Action?
By the way, I want to buy Action! I see Action 5 being mentioned a lot on the Steam forum and I want to ask if I buy Action 4, will I be required to buy Action 5 again?

Yes, absolutely. Mirillis Action supports recording system audio (sounds from games, music players, etc.) and recording from the microphone simultaneously or separately.
