Green Screen Chroma Keying with the HD10U at DVinfo.net

Green screen leaves lots to be desired with this camera. Especially when your final output is HD. You can get away with a lot if your final output is NTSC which was the case for me on this project, thank God.

The chroma noise and MPEG compression, I beleive get in the way of good chroma keying.

Here's the final product which is the results of much tweeking and multiple masks in AE:

P.S. a good hair dresser would have also helped ;)

Where do we get the 3ivx codec to watch this Frederic?

Paul,

You can see compression but the file are VERY small and clients really get the idea.

I find it to be a very good viewing codec.

Looks great to me, and at ~ 57 Megs a Minute you could fit around 12 minutes on a CD. I've used Windows Media 9 which gives a slightly smaller file size (I think). This look like a nice distribution solution for the Mac. There is also Divx, but the encoder expires, is this encoder free?

Free for now but they'll start charging in no time.
