In this case, what I'm hoping there is a way to do, is when shooting against a green screen, when it's necessary to move the camera, be able to lock down whatever background, etc., so that it doesn't move with the camera. I have a scene where the subject is sitting at a table, then stands up quickly to deliver a line to the other person in the scene.

I need to be able to lock down the background so it doesn't move when the camera does...and I'm hoping I'm explaining this correctly lol ... it sounds a bit confusing as I'm typing Mike D

Hi Mike

If you're shooting using a correctly lit green or blue screen (there's hundreds of YT tutorials on how to light a green screen) there shouldn't be a need to "lock down the background".

1. In PD insert your green screen video with actors props etc

2. Insert your background on another track - still backgrounds work best eg a photo of the Eiffel Tower.

3. Open up your green screen in video and the PIP designer will open and use the Chroma Key to 'key' out the green and leave a clear background.

The 'actor' in this clip (25 sec mark) was standing in front of a green bedroom wall!

Greetings!

Thank you so much for the reply and information...I believe I may have incorrectly explained what I'm attempting to do..I was mentioning locking down the background, when I meant lock down the camera. It has been my understanding, that unless you can do some sort of motion tracking, if you move the camera while shooting against green screen, whatever image you replace it with, will move as well.

I want to do a hand-held shot of my subject at the desk...I'd be kneeling in front of the desk shooting him at an angle, then when he suddenly raises up from the seated position, I'll follow him with the camera...if this is shot against a green screen, wouldn't the background image we drop in move with any camera movements I make?

I apologize if I am not explaining this correctly...some of the terminology eludes me at times when I'm attempting to do something I've never done before.

Thank you!! Mike D
