the question is do i need a webcam or no

That depends. If you wish to use a webcam, you can, or no need.

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)

i mean do this thing automatically give you webcam or no?

personaly.
no.
its a option.

wait so if i turn on the option will the video automatically have my face

Hello madha,

Please refer to the "Recording settings - Webcam (PiP)" section on the linked page to learn about the Webcam overlay function of Bandicam.

Also, you can use Device Recording Mode if you want.

We recommend you try them with Bandicam trial version.

Thank you.
