Hello,
with wich software can i make some good Videos from my market-Place products?
Kind regards,
Andreas
anything that records your game-play or screen, fraps for gameplay, and i use microsoft expression for screen recording 
If you have a series 6 or 7 series video card from Nvidia you can use ShadowPlay which does a very good job of screen recording with or with out a microphone.
Or you can use Matinee to record and then another video editing software to convert the output to a usable format.
