Moire effect with HVR-V1U at DVinfo.net

Is anyone else experiencing a pronounced "moire effect" with their Sony HVR-V1U? It seems most visible on greens in intense sunlight, and on thin bands of concrete or steel in sunlight. The "buzziness" on edges of buildings and on railings seems extreme as well. I never had this much moire with any of my earlier Standard def cameras, including my PD-150. Could this mean there is a problem with one of the CMOS sensors, do I need to adjust some internal setting, or is this a common issue with this new camera?

Your description of the problem is not clear enough. However, if you mean line twitter - does it show in progressive mode only? If so, make sure your clips are not deinterlaced on viewing device (HD, I assume) input.

Try to play them back using software MPEG player with deinterlacer off, and a HD monito connect vid DVI-D.

However, if you mean "marching ants", "mosquito noise" or "busy pixels" - I'm afraid this is inherent in this great camera; my advise: just forget about it, and enjoy your videos!

What are you viewing the image with? If you're watching an hd image with an lcd tv that scales the image badly to another resolution then you will probably see a lot of bad moire.

I've shot with the camera in 24p (not A) mode on both the 1080i setting and on standard def DV in letterbox. The moire is there in the original footage, and then I downconvert from the camera in HD or playback in my standard def DVCAM player. I'm playing back on a standard monitor, but since I'm not editing in HD that shouldn't be an issue, and, as I said, the moire is there in my viewfinder when I shoot. I'm wondering if it could be something with the 24p mode.
