Integration of live-action footage and computer generated imagery.

These images are in jpg format but I render out png images that have alpha key from Daz Studio on my PC. I import the images into Final Cut Pro on my G5 if nothing more than color grading needs to be done with them. Otherwise, I import them into Adobe After Effects on the G5 if I want to mix live actors into the scene.
For instance I could walk from behind the cabinets to the sink and from the sink to in front of the table with my back to the camera or sitting at the end of the table facing the green television or sitting at the table facing the camera. The stool I sit on can be real in the scene or covered with green and swapped with a CG stool. I can put a real bowl of cereal on the table and eat the real cereal with a real spoon. I can lean on this CG table due to the real table being covered with a green cloth. Ditto the sink area where a box of cereal and the bowl sat before I bring them to the table.
I can move the camera in a parallax fashion giving more depth and I can rack focus putting emphasis on the subject. I can change the green of the screen on the television to be a photo or movie. Either I key out the green there or simply corner pin the movie over it.
HERE IS THE QUESTION
There are all these cool Sci-Fi Hand Gadgets by Nightshift3D for instance and by other vendors. Weapons even. Even a simple mop or broom, cup, ball, etc. I would like to pick up these objects and "appear" to be using them.
Any idea how I would do that? I don't have room in my small apartment to collect real props. Maybe I could get a few wooden dowls of various thickness and paint them green along with a few cardboard boxes painted green.
I can do motion tracking with markers on the green inside After Effects.
Thanks for any input or even an interesting link. I just don't seem to have my head wrapped around this yet.

Quite a project I must say=) Are you planning to do animated stuff using this technique? Would LOVE to see something like that!
Have an approximate green object you can track and overlay with the 3d render to composite. This is difficult depending on the shape; A sword or gun is easier than a irregular shaped object for instance, like maybe a pillow. Planning is key here.

Still working at it.
I could never figure out how to make it work without looking like a 1990s FMV game.
Those 1990s full motion videos were low resolution at 640 x 480 or less. They were also tape so there was that crap quality too compared to a clean digital 640 x 480 of today.
Try again and post a link here to your upload on youtube.
very good
but
given your username do you only do nude greenscreen captures?
that could limit YouTube friendliness if going full body
Hence, I don't do full body shots. The director yells out, "CUT... STUNTMAN!"
Wait a sec... I'm the director....
For a micro budget production this teaser trailer looks great.
if only Bunnings hadn't wiped out all the competing hardware stores near me before the up and moved far away I would buy some green paint and do a wall myself ????
Try green (or blue if your actor is wearing green) cardboard (about 1 1/2 x 2 feet each) and green masking tape from the office supply store near you. Where I am in Montreal, they only cost a dollar each. Would love to see what you do with it. Just light evenly and separately from the actor. Actor stand closer to camera away from green to make keying easier.
yeah even Officeworks (and an actual paint store near it) are 4 train stations away, not far normally but not happening with social distancing laws
Bunnings and the 2 hardware stores it out competed were walking distance, was really annoyed it moved, there is a further away one but easier to get to by train in the other direction too.
Do they deliver? Do you have any green or blue bed sheets you can hang up?
I tried that last year
didn't work well
I even have a blue wall I tried
You are so right. What is probably not showing on the books is his perspiration. He is graphic artist on the Jimmy Kimmel Show in New York.
No gloss just matte? Lighting is important. Must be even for easy keying. (easy... ha.)
Backlighting the actor(s) also helps a lot. I made a blue screen several years ago by just buying a length of cloth from a fabric store and nailing it to my garage wall. I now have a proper green screen, which can be acquired quite affordably.
Exactly Gordig. Two or four lights on the green and then three point lighting on the subject. Some don't use the backlight / toplight because there is none in what is being used as background.
Sure enough, someone used a pillow to greenscreen general Zod's armor which is CG.
