I have done numerous green screen shoots both indoors and outdoors and I agree with what has been said by the others. Another good source to learn more about green screen work is the Visual Effects for Directors series from Hollywood Camera Work.

As I said, having done chromakey work for years, I was happy to learn a few new tricks from this series.
Best of luck!

One “less expensive” alternative is to rent an optical stabilizing lens. They are not the cheapest lenses to rent, but they work well.
Best of luck!

2 things that can help. Re-record the music with 4 clicks at the beginning using the same timing as the music. This is referred to as a click track and you can achieve it in Garage Band or similar program. Lining up the clicks in post is pretty easy. The second thing is to use a slate. If you close the slate on one of the clicks (keep it consistent) you will also have a visual reference for syncing.
Best of luck!

I like the Ultralight Control System. I got mine at Filmtools.com. The joints tighten down better that the Noga style arms and you can get a variety if arm sizes that interchanges for any configuration. I use mine with the 8″ Panasonic monitor and it works great. I also like the bracket that attaches to the monitor itself. It grips tight, and has a platform to give the monitor more support.

I have used the black cloth trick as well as black foam core mounted to the dolly to allow for moves. Both have yielded decent results. The fact still remains that you must try to keep as much light as possible off of the camera rig. A polarizer can help, but you lose quite a bit of light and it will only help in certain angles.

If it is a true black limbo you want, be sure to keep the subject as far away from the backdrop as possible. Also, flag the key and fill lights off of the backdrop to eliminate any spill.

Mark,
I agree that a difference matte can be easier for production but would I think with the background moving at a different speed you would want to get make getting your matte as easy as possible. We do this kind of stuff quite a bit and it’s really no big deal to throw up a chroma key backdrop once the camera etc. is all set up.
As for the speed ramped background, your motion control operator will be able to calculate the speed difference based on how fast you want your background to move and enter that info into their system. We really like Pacific Motion out of Burbank.
And I agree with the Gondry and Jonze DVD’s. They are great.

This was most likely done with a motion control rig. The camera is placed on a special, computer controlled, motorized dolly and track system. The move is created and stored on the computer to be able to replicate it perfectly over and over again. The background plate (i.e. people moving in the background) is shot at one frame rate/shutter angle and the foreground plate (i.e. the man sitting at the table) is shot at a normal frame rate. The foreground was most likely shot in front of a chroma key screen. Each shot begins with a sync mark, usually a red led light flashed at the lens, so the shots can then be composited later.
This is a common technique used in films and commercials. David Fincher used it to great effect in Panic Room.
Best of luck!

The grain is definitely the ground glass from the lens adapter. There are a few factors that can add to this problem. I only work with the Pro35 so I can only speak to my experience with that system. There is an adjustment dial on the Pro35 that allows you to change the speed of the rotating ground glass. This helps to hide the grain in most of the image when dialed in correctly. It looks like ____ when it is not. It takes experience to analyze the whole image and determine the correct level of compensation before hitting record.
Also, on a clear, bright day (like in your image) if the camera is stopped then the increased depth of field with exaggerate the effect even more. Lens adapters crave a shallow depth of field. Tell the shooter to use ND filters to get the lens close to wide open.
Finally, if the detail in the camera was turned on at all, it will exaggerate the effect as well.
Unfortunately I don’t have an answer for a fix in post. You know the old saying, “Garbage in …” I think the multiple layer, blending mode, key out the sky idea is the right track though.
Best of luck!

I, too, would try to stay away from keying out the monitor as it is sooo difficult to get good, clean edges. However, another idea for the keying the monitor is to just run a full resolution green/blue desktop image so you don’t have to worry about taping, using cloth, paper, etc on the screen.
