Putting video on greenscreens in video
Dear cowpeople,
I’m going to make a little video of one cameramovement above a table.
The camera will start below the table, raise until above it, then slide above it.
On the table will be green papers where I want to add other video’s.
Like there are little screens laying on the table.I’ve made a little example movie

I know the lighting and quality aren’t that great, but it is just about the cameramovement.I’ve seen greenscreen tutorials and track movement tutorials, but I have no clue how I can add a video in the green paper that will follow the cameramovement.
Are there any tuts that I’ve missed that’ll explain what I’m searching for?
Or how can I do this?I hope you will understand my bad english and can help me.

Simple corner pinning should do. The problem is, your shape isn’t very clean. I strongly suggest you use some heavier cardboard as a placeholder. Make it the right sizes and paint it in a saturated green (not the pale one in the clip) On the corners, add some squares in a different color (red preferably) to use as track marks. Make sure they are aligned well. You may also wish to add an extra marker at the center as a backup measure. In case you need to match things manually, it helps if you also mark out the “wireframe” by drawing some thin white pencil lines from corner to corner across the center. Once you have that, film your stuff. The first thing you do then is ttrack your red corner markers using the corner pin method. After that it’s up to you if you need to get rid of the green and red areas by keying/ masking them or you simply overlay your other video to hide your placeholders.

And it would be great if you used a sheet that is not crumpled (just learned a new word here..sorry, I’m french). It would be a lot easier to have a straight sheet, or else you’d probably have to use Blendind Modes to match the crumples (?). I know that if you putted your video just on top of the cardboard you wouldn’t see them, but to me, it’s just a matter of precision that makes everything easier to accomplish.
I bought little red stickers at a cheap store and these work so great when it comes to tracking. You could just draw one yourself but…it was 3.99$ for 200.
Good luck!
