We need a tad more information here.
Does the aspect ratio of your project on the timeline match that of the video?
Do you lose edge material from both the sides and the top and bottom?
Most camcorders do "overscan" and actually capture a bit more than you see in the viewfinder or on the LCD. I once had a lens hood fit on my wide angle that did not appear in the image on the LCD or viewfinder, but once I imported it into an editor I could see edges of it. Fortunately the editor allowed some zooming into the video allowing me to effectively "crop" it out.
