Moving a cropped image
Hi there,
This may seem like a dumb Q but I’ll give it a shot to see what the pros think!
Let’s say I’m filming against a green screen background. I’ve zoomed in far enough that the subject is (more or less) central, but the video camera still picks up the very edges of the filmed area (which isn’t green screen!)
To rectify this I crop the image in Vegas 8, which gets rid of the sides, and that’s cool, but then if I try to move the cropped image (for example the subject may no longer be central), it starts to bring in the areas at the side that I didn’t want.
My question is this – can you lock a cropped image to avoid this happening i.e. when you move the cropped image only the visable area is moved?
I’ve read about masking on this site – is this the way to go, or is there another way?
Any advice is greatly appreciated!

I would use the Mask tool instead of cropping. Since this is being keyed, just mask the area outside of the green screen so that it isn’t included in the shot.

Thanks for the advice JR – I’ll try masking instead!

Hey Brian,
Sorry I’m a little late to this party, but I think that it should be pretty easy to do what you are talking about.
If you go into your Pan/Crop function on your event and make sure that your “size about center” button is selected.
Then whatever you crop in the image will appear in the center of the frame. In other words if you crop 30 pixels off the right and 50 off the left, the final video should have 40 pixels cropped on each side.
But to make this work exactly right for you, you will probably have to turn off “lock aspect ratio” right above the “size about center”
