Motion blur in 1080 60i

Here's the scenerio:

Shooting HVX200 1080 60i with a century wide angle converter on the front end. Shooting indoors and out. Lighting with HMI's inside and out. Using Firestore with firmware update 4. The camera is set to video and not film cam under scene file settings.

Mac OSX 10.4.11, FCP 6.0.2 on a MacPro with 2 x 3.0 dual core, 8gb of ram, 7.75 terabytes of CalDigit S2VR HD
Sequence is set to DVCPROHD 29.97

The problem: When the camera is stationary and I have someone walking through the frame (not at the camera) I seem to be picking up motion blur. The sharpness of the person's face is going soft as they pass by.

Any guesses as to what the problem is? I've shot with this setup many times before without issues. My static shots with no motion are beautiful. But once motion is introduced to the shot as described before the image just goes down hill.

Shooting interlaced should have alleviated all motion blur. But, it's just not working.

Your help is appreciated.

Interlaced is just as susceptible to motion blur as progressive. Motion that moves quicker than the temporal difference between frames or fields will blur- that's just a fact of life. To minimize that, increase your shutter speed.

Thanks guys. Sorry it took so long to back to the thread I started yesterday. I considered the shutter issue. The shutter was turned off... which if I am correct would make it 1/60. The motion being filmed was simply someone walking casually across the frame/scene.

The motion blur did not appear in my Marshall monitor via component cable while shooting. However, it appeared once I brought the video into my FCP6 project.

Hmmm!
