Gameplay video capture

[special_ta]

Good day.
<Apologize for my bad English>
What is the best way to record gameplay video ? With the capture button allowed only 30 seconds?
Is there a software for unlimited capture ?
Do I must buy external video capture? Can you suggest the best one for this job?
Thank you.
