I just got a film transfer system to copy 8mm film to a tape using a video camera. The system uses a front surface mirror and a ground glass screen. The projector projects onto the ground glass screen using the front surface mirror to correct left to right imaging. It looks great on the ground glass, but when I try imaging with the video camera there is imaging blooming when the image is bright. I don't think it is the camera, any ideas???

I have no idea what you are talking about. I am just interested in getting information about 8mm film and what others are doing. Have no idea what ICQ ID or AIM ID are. If this not good enough, then......

Hotspots are a common problem with realtime transfers. Here are a few things you might try:

1) Try replacing your lamp with a lower wattage.
2) Darken the camera image with exposure settings.
3) If your camcorder can us external filters...try using an ND filter.

Here is another thread where an ND filter helped this member.

I found that using the longest focal length lens on the projector available cut down the centre hot spot. The ground glass surface could refract more light at the edges into the camera lens that way. I suspect using the telephoto end of the zoom on the video camera (if it focuses close enough) would help also.
