well, even in the trail i think there is a option for it.
webcam injection is nice on playback so others can see your "expression"
there is even a option to insert a smal logo.
and as for the worth buying it.....
i tried it 10 minutes, noticed it did what i wanted, INC bandicut, so i bought both as package.
and yes, there some glidges,, but bandicam cant fixed them if there is no feedback (glad there is this forum)
