Green screen botched it.

looks like you have your track order reversed (the wrong one on top)

I have the video on the top and the image as the background on the bottom. Isn’t that the correct way.

The blue you can see is the background, then there’s me. The black you see is where the green screen was and is meant to be invisible only it’s stayed solid black.

Do you still have the “Show mask only” button checked?

Hi James thanks for the question – it’s unclicked.

[John Rofrano]

Can you post your images so that they display in the post?

I don’t download random ZIP files (sorry).

Yes of course John That’s what I thought I was doing only it didn’t seem to work that way.

How do I do that? If I click on the file upload and then add the file it takes me to a post, do I add the details and click post?

[Kayley Grace] “How do I do that? If I click on the file upload and then add the file it takes me to a post, do I add the details and click post?”

Once you select the upload button it will give you a window like this:

Then cut and paste the Embed URL into the text of your post. It’s important to cut and paste the Embed URL and not the Link URL.

Ah ok I realized I was clicking on the wrong upload button.

what i started with in sony vegas – this is an image of the video i am working on

What I ended up with. Where the green screen is it’s black and sits on top of the blue background.

[John Rofrano]

Are those snapshots of the Vegas preview? I’m trying to understand why there are black bars on the sides of the original shot and also on the keyed shot but to a lesser extent. Was the video recorded at a 4:3 aspect ratio?

How do you have your tracks composited? You did something wrong because normally the background would show only where there is green but your video actually shows outside the green screen which leads me to believe this was shot in 4:3 and then you composited the tracks together somehow (which is not required).

Try this:

1. Start a new project.
2. Add the green screen footage to the project as a new track.
3. Add the Chroma Key plug-in to the event and key out the background.
4. Add a track below with the background image you want

You should see something like this:

Yup John I agree that is what it should look like only it’s not.

I have started a new project, have gone through all the steps.

Added Chroma keyer to the video by dragging over to the video window.
Used the colour selector to select the right green
Clicked show mask only then
Changed the threshold to get the black and white split.
Unclicked show mask only.
Added by back ground video below the green screen video

Then where the green screen is now black is what stays so it doesn’t become a transparent background showing the below image it stays as a black background.

Does that make more sense?
