Q: Panasonic sdt750 breaking signal . Fix from camera or FCP express?

Hi. I got the Panasonic sdt750 and since I don't know this camera very well I went to a party and every time that a photographic camera took a picture, the video breaks for 3 or 4 frames. How can I fix this? From the camera? With FCP express? I noticed that the other Canon I have don't break signal in front of flashes..Thanks..

Final Cut Express, Mac OS X (10.6.8), 2.8 intel core duo. memory 4GB 800

    That condition is usually the result of the image sensor and/or the signal processing circuitry of the camera not being able to handle the sudden change in scene brightness caused by the flash.  There's no fix that I'm aware of other than using a better quality camera.  In post, you could cut out the offending frames.

    It's an artifact of CMOS sensors called Rolling Shutter.

    The Canon probaly uses CCD sensors.

     

    See here for some details:

    The newer FCP X program has tools for correcting/(making less worse) the issue.

     

    You can download a free trail version if you wish to explore the feature.

    Thank you very much. I was using the camera in manual mode under the flashes in a place with a very low lights. I did the same in IA and it's now a lot better. Didn't dissapear but now it's tolerable and easier to fix.
