I know there is a thread having to do with this, but it seems like no one has posted anything more about this topic since march...

I just recently bought the DVX100 and discovered large "color blocks", also known as "macroblocks" throughout the footage when any minor adjustments in color were attempted. I also noticed that when desaturating the image completely they also became noticable in certain areas. I have since returned the camera to panasonic for either repair or replacement. I have been studying stills from other users footage that are displayed in these forums and have noticed the same marcoblocking, but I guess the camera owner never noticed this. I also compared stills from my XL1s to the DVX100 stills and when I apply the same filters, I see none of the color blocks that seem to be inherent in the DVX100.

Anyone have any insight into this, or have any comments or suggestions as to how or why this occurs? Has anyone else noticed this with their footage?

I do admit the 24p and cinegamma features create a beautiful image and without applying any color correction filters, the footage surpasses any other DV camcorders I have seen.

Can you post some samples? This issue has come before around different codecs and display settings.

I could if I knew how...I don't have a web page to post on and you can't post any pics on here. If you have any suggestions I would appreciate it.

Just in case this makes a difference, I am using the following setup:

Powermac G4 dual 1GHZ 1.5GB ram
Final cut pro 4

I've seen two threads dealing with this issue, and I believe that both times it was determined that the camera was defective. So, it depends on what your particular circumstances are, but if you're seeing something that looks noticeably bad, the chances are that your camera might need a repair.
