Advise me with Chroma Keying in Sony Vegas!!!!

[Kelden Amadiro] “Yes. What’s wrong with it?”

The colours are washed out, it’s fuzzy (out of focus?), there’s a shadow (bottom right of the screen which tells me your talent was too close to the screen) and the background is not even close to being a saturated green (look at the vectorscope and you’ll see what I mean).
All in all, a poor video for chroma keying.

I’m using a green paper for the background meant for this purpose; I tried cloth, but it had wrinkles in it and I was told not to iron it. Is it not possible to greenscreen this way?

Wrinkles only matter if they cause shadows. Your background isn’t very green to begin with, probably due to improper lighting and talent distance separation, as Mike mentioned. I was able to get something out of this, see attached screenshots.

I was able to key it like Jim did but your biggest problem is that the background needs to be a LOT greener.
Drop a solid green (it’s a preset) on your timeline. That’s what a chroma key background should look like.

Thanks Jim and Mike!!!! This is very helpful!
Two more questions:
1) I have two 500watt softboxes 9 feet away which obviously aren’t lighting it evenly. (My room isn’t wide enoguh to have them totally from the side, they are both sort of forward from either edge of the greenscreen) Should I switch to 250 watts, or do something else?

2) Would it help if I switched to a brighter green background paper, or is #1 the main problem?

Thanks!!!

PS Could I ask you to take down those photos of me! A bit uncomfortable to see me staring out of this webpage! Thanks…

Maybe a moderator can delete the photo in my post, I don’t know how to do that.
