I see what you mean.
Are you using the color picker (eye dropper)?
Because if you pick a spot on the green screen before you adjust then the screen should look black not blue
If so then pick a square the size of her head , right above her head..really close without touching her hair.
use the mask check box and it will also show bad areas of lighting.
get the subjects to be all white and the green screen to be black.
If the lighting, distance spacing, amber back fill is all done right then
you should be able to get a good key with only moving the sliders about 20%
of their travel.
Your subjects are so close to the screen that there is an insane amount of spill on those edges. All that wood should be leaning on something in the air above the set and 10 ft away from the screen.
Notice the key is good across the top of the helmet and on 1 edge of the wood.
Its the reflected green that is killing at this point
Do my yellow/amber light trick from behind the subjects to neutralize the green spill you have spill on the edges of EVERYTHING! the way this is setup.

Put her hair in a pony tail or bun and I think you can make this work.
There is potential !!
Good luck

Understood.

I dont know the size of you screen but….
with an 8×8 screen I recommend this setup with what you have
If you can get the subject 8 feet away it helps a lot.
The lighting you have is fine .

Sounds like its some home depot worklights at $39.95 a tree
Thats OK but take off the protective grills. also open the glass cover and rotate the bulb so the molding tits are facing the back.(Dont touch bulb with bare hands !!)
Also what helps is get some cheap shiny aluminum flashing (home Depot)
and rebuild the refector. The stock one creates bad reflection artifacts.

Place the lights about 10ft or more from the screen and 45 degrees to it.
Off the side, approx same distance as subject.
point the 4 lights at the 4 quarters of the screen. The left lights point to the right side, right ones to the left side. Depending on the camera… Use the zebra setting and open the exposure until you just see zebras. Now move the lights around till you get an even zebra wash.

Use something to keep the lights from hitting the subject.
Light the subject from 45 degrees angles as well but use something to block its light off the screen.
Shoot , try again

Let me know if there’s a difference.
Thanks Zipedit

Its all done in the custom setups pages.
How did yours come out ?

I agree with Gary.
Save the hassle and use a clapboard.
Some kind of visual and a hard quick staccato sound.
I shoot local rock bands with multiple camera’s
each camera is of a different brand or quality.
Some are $300 cheapies that friends own and operate.

The point is…Drunk friends dont understand anything more than..
“point at the drummer when he clicks his sticks together at the beginning of the song.

Works like a charm.
In post I line up the camera’s audio waveforms. trim the front end, drop a marker, name the song. then if I slip by accident I can see that it moved from the marker.

Count the seconds in labor…..its quicker, simpler this way…a lot.

all I can say is
WOW !
We posted a few items on youtube and this is far better results.
We just followed the recommended format and ran with that, prayed for the best.

Great lead Mike!!

Understood !

However.. I don’t, haven’t run into that at all.
? How much of the pants change.
just the very edge or the whole thing ?
Does it look like a spill issue or a full color shift on the shirt or pants.
Try a opposite color shirt, see what happens. a Magenta shirt ?
I’m very curious on how this is happpening to you.

I have a fill light that has an Amber gel on it that is back by the blue screen and points at the subject. This creates a amber edge along the subject that counteracts the blue spill from the screen.
How close is your subject to the screen ?

I do alot of keying in Vegas. I spent the time on lighting, and settings in vegas. We are able to get very acceptable results….only when its’ done right though.
I am not experiencing what you have going on.
Seems as though there might be a filter or effect somewhere else in you video chain that is being affected by this.

Do you have a third party video card for output?
Is it happening in the preview window and on external monitor.
Is your track composting mode set to “source alpha” ?
Maybe have to do a Vegas default settings re-set and try again.

Seems like you get the concept and I bet there is a simple solution to this behaviour.
I too am resisting getting “Ultra key 2”

Have you taken a look at ” http://www.blufftitler.com ”
A 3d titler that is very simple to use.
I use it in a simple sense. Just to add depth to text as it slowly moves.

lighting , shading and fly motion capabilities.
Give new meaning to the same old veges look, moves.
I too ran into your same quandry. I pushed Vegas titling to the limit, needed a boost
Very cost effective as well.

superimposing your son without a controlled set
with proper lighting gets into a whole other realm.

1) yes the mask will follow the edge of your video motion.

2) if he is running around you will need a large bluescreen set with alot of even lighting.
However…maybe experiment with some short tight shots.
Get a small Blue screen. maybe 8×8 feet.
you’ll have to match him and your angles ahead of time to the existing footage.
maybe film him down low at the snap,
then cut to the last step before the throw.
take out the running stuff cuz running in place doesnt look real.

you’ll soon find matching angles, depth will be you enemy.
experiment small and fine tune.

also see the links from the other responses.

We do alot of blue screen work.
It takes alot of trial and error.
Lighting is crucial !!!!!!
Look up “chromakey” in the help file to understand the Vegas controls.

You can test this easily with any solid back ground.

-film a colored ball against a white wall.track 1
-add a chroma blur effect to the event, set it to medium.
-then add the chromakey effect to the same event.
-use the eyedropper and make a small selection of the white wall.
-check, use the “mask” button to see how tight your mask is.
-solid white is not transparent and black will be transparent.
-place a different video event below. (track 2)

-adjust the hi, low sliders to get a clean edge without over doing it.
-You will notice subtle “foaming” where the light isn’t an even background.
-experiment with the controls to get a clean edge.

you should now see your ball sitting on top of your background video.
-dont forget to uncheck your “mask button.

The blur slider softens the jagged edge. easy does it !

This is the basic fundamentals.
Green and blue are commonly used cuz their colors tend to be rare.
you can get very complex with other chromakeying sofware
Ultrakey is very popular.
but with good lighting, technique and practice Vegas does a pretty good job
