oranges and reds at DVinfo.net

Menguc Tanriseven · October 31st, 2004, 10:32 PM

The reds and oranges in my footage looks fine on the monitor but when I capture it (or even when just viewing them in the capture viewer screen) on FCP on mac, or Imovie, the reds and oranges have halos around and jagged stairstepping look.
Everything look fine on the camera viewer and playing the footage on TV, but when it comes to viewing on computer it gets massy.
Here are two examples as what it looks like:

I am shooting in Advanced 24P and capturing in 24p advanced pull down. Is this something related to compression?
I would appreciate your help
thanks for reading.

Thanks for your reply.
How come I do not see this artifact in viewer window, and also not on TV monitor, but only when I try to capture it?
thanks

It tends to only appear on hi resolution Progressive scan monitors, however, i have seen some really severely bad footage that this also was visible on a TV. IT has to do with the DV compression, and I would not reccomend desaturating footage just to get rid of it, it will just end up desaturating the rest of your footage, and you will still have some fringing. The Vegas tool works great and I see no visible side effects, except for a slightly longer render time.
