tom wolsky chroma key HDV question
I have a thread a couple down and while searching came across this quote of yours. Some say chromakey in HDV is no good. You say it’s acceptable. I have been chromakeying with no problems in HDV and suddenly on of my images in pixelating like mad. Help.
“Tom Wolsky agrees:
You might want to restate it when you write: “The HDV the compression process removes almost all the color information from an image.”
I don’t think it’s accurate to say it removes almost all the color information from an image. You make it sound like it’s going to practically desaturated. -

Anybody else seeing this happen?
Looks like compression artifacting. Clearly not caused by the chromakeying as it’s clean without the text. Adding the text seems to cause a problem. Is that a double byte font BTW?
All the best,
Tom

So it’s a compression issue. It’s not caused by the text bc it appears randomly. The footage looks fine with the blue screen. The artifact frame happens seeming arbitrarily. When I tried to reimport the footage, FCP is acting up and isn’t responding. Going to trash the prefs.

It certainly looks like compression artifacting. What I’d suggest is, given the background is highlight detailed and if it’s moving it will be stressing out the MPEG2, is to blur the background a bit and see if that helps.
