XM2 Red smear

Hi,

I have just got a new XM2 and have noticed that deep reds smear (blur, blooming etc) slightly to the left. It's not to bad. You don't really notice it untill there's red on black. I have seen a few posting saying similar things. Is this a typical XM2 problem?

Thanks,
Will

"Love Lies Bleeding"

Are you seeing this in the final viewing on the TV? Maybe just a fine tune of the TV colour needed? Another thing, is to see the same effect from "Broadcastd" stuff - then be critical!!! - I'm starting to get a name in my family as the "Red Baron!"

As you say, much has been said about this - I think I joined in at one point and gave my "feelings" and airing, just after I purchased my now BELOVED XM2 . . .

Grazie

I can see it in three different TV's and they're all good sets so I'm guessing it the cam. I don't see it on the LCD or viewfinder & I don't see it on the PC, just TV's. But I don't seem to have any of the other problems that these cams can have so I think I'll have to put up with it. Is it a common problem? or should I consider sending the thing back?

Interesting. Do you connect XM2 to TV by s-video cable or by supplied banana-like?

If it's not smeared on the camera or the computer, but it is when you use the supplied cable, then the rca cable is just crummy.

Try the S-video cable and it should improve a little. You'll always have some smear when you go to analog because the reds are hard to hold but it shouldn't be really noticable or catch the eye.

Thanks ben, you're right. I used the S-video and you can hardly see it. Cheers

Keep in mind that DV (CCD?) has problems with the color red.
I try avoiding it with my XL1s.

CCD red problems are well understood by the industry. There is usually a special digital filter somewhere in camera video processing path that removes all the CCD red artefacts.
I'm probably not knowledgeble enough in DV coding, but I see no reason that red is more problematic than blue for the DV encoder/decoder.
On top of this Will says there is no red artefacting when seen on computer. Then I'd point to PAL encoder as a possible source of trouble here. This is why S-video cable might help, as color is encoded somewhat differently in s-video.

I have never seen such a red-artifact removal tool. Can you point
me to one? Do some NLE's have it?

Thanks!
