Hmm. Did you get through Apple's tutorials (you mentioned "tried to read..")? The tutorials that come with Shake are very good, at least for me.
Also, I'm not sure I understand what you're trying to do. Are you keying existing footage? Or, are you trying to shoot your own green/blue screen shot with an actor, and then composite over a background shot of NYC?
Basically need those two elements: your well-lit actor against a well-lit green or blue screen (go with green if you're shooting DV), and background footage or an image of NY. Then key your footage and composite in Shake. If your camera is not locked down, that's a whole different thing that I won't get into with you now (so, make sure your camera is locked down on a tripod and not moving, to make things easier).
But for starters you should grab a book on the basics of compositing. Wish I had something to recommend, but again, the Apple tutorials and the Shake book should be enough to get you going in the right direction. Spend some time on the tutorials, commit to them, and you'll be fine.
Hope this helps-

Can Motion 5 replace a green screen and blue screen in the same shot?

Can Motion 5 replace a green screen and blue screen in the same shot? I would like to replace a green screen with one image, and a blue screen with another.

Fox gives a good example for keying green & blue (or any other color) from the same shot. I'd suggest doing a few things to get better accuracy.
First, the motion keyer always removes the color it detects the most of by default (blue/green). You can override this by setting the Strength parameter to zero, then use the Color sample tool to select the color you want. The advantage is motion will do a good job of targeting only the hue (color) that you want to remove and set an appropriate starting softness. It also will remove spill based on this color. Looking at Fox's example movie and the shot, I'd approach the same shot this way:
Remove the Blue
1. Apply the keyer and set the strength to zero.
2. Use the Sample Color tool and select the blue (or other color) to be removed.
3. Decrease the spill level (if needed). In Fox's example the spill from the blue glasses is going to be minimal, especially compared to the green screen, your shot may need different adjustments. Only de-spilling what you need to will give you more accurate color right away and minimize additional color correction that might be needed later.
4. Use the Color selection tools (Chroma wheel/Luma bar) to fine tune. Ideally you want a minimal tolerance, the inner selection, with a nice fall off, the outer selection. Try with the Scrub boxes setting first, then switch to manual if you need more control. Again see Fox's example.
Remove Green
It's the same as the blue, you could apply the keyed to the same clip or a parent group, at this point it's many user preference.
With these techniques you can remove any color from a shot or create a mask based on a color. BTW, as you are learning to use the keyer I'd highly recommend having the Color Selection open so you can see the graphs. These give you real time feedback as you make selections and changes with the Strength, Refine and Color selection tools. Watch what happens as you make selection or changes, sometimes the problem area is actually in the brightness not the color, or the softness may change more than the tolerance selection. Observing what is happening in these graphs will help you figure out wha to change and speed things up.

Creating green screen vids and overlaying them on Flash sites

I've heard of a thing where I can record a video in front of
a green screen and create a flash movie to overlay on a flash
website. It almost looks like the person is living and walking
around on the site. Can some one please give me more info on this
and the tools I need to make this. I feel like I'd need the Media
Server to serve this, but I'd use Premiere to edit video, right?
Thanks in advance.

Your thinking is correct. You'd use something like Premiere
to chroma key the green to a transparent background (I'm sure
there's a pile of tutorials out there), and encode to a Vp6 flv
(sorenson spark doesn't support alpha channel). Now you've got a
transparent video, and everything in your flash movie (at a lower
depth than that of your video object) will show through.
For delivery you could use FMS, but it wouldn't be a
requirement.You could just as well serve the video via http
(progressive).

Is there a way to green screen and do a picture in picture in iMovie

I was wondering if there was a way for me to be able to do a green screen and picture effect at the same time
Or in other words, is there a way to select two of these at once?

NiCKC17 wrote:

In short : No.
… but there's a workaround:
create a project with green screen first, export it, re-import it to iMovie, apply pic-in-pic ...
Or, dare the plunge to a professional tool, FCPX …

Green screen and box locking up sometimes?

Hi All
Well we have had BT vision for 2 weeks now and are enjoying it but we have had a couple of problems.Sometimes while we are watching TV(freeview) the box reeboots and we get the BT vision start screen (blue) with boot count 01 in the bottom left corner.The sometimes we get a green screen and after about 5 minutes it reboots to the start screen.And then this morning it just locked up while my son was watching disney XD (picture frozen) and would not respond at all so I had to unplug the box and power it up again(reboot screen ,starting BT vision) and now it is working fine.Is this to be exspected or do we have a faulty box? Thanks in advance

All software is essentially in development we don't need to call it Beta. My Mac etc as does Windows or phones constantly are updated.
So it is with BTVision

How do you use green screen and picture in picture in iMoive at the same scene?

I understand how to do green screen and picture and picture... but how do you do it in the same sequence.. so when you are speaking with a background picture and you want to add a picture or a story within that picture... there has to be a way to do that..

That is a great idea! So I just do everything to the clip involving the green screen. Export it to, say my desktop. Then import it back into iMovie. Then I will be able to add a picture in picture? Fantastic! Thanks so much!

Green Screen and Photoshop Elements 11?

Hi. I have tried multiple ways to remove the green screen in photoshop elements. Being new to this program, I've found ways it was done in previous versions that don't appear to be in 11. The MagicWand doesn't get it all out (gotta love hair with green in between ). Is there an easy way to be able to put a digital background on?
Thanks!!
Khrista

It appears I wasn't told the truth today by Adobe when I chatted with their rep on-line. I specifically asked "if Photoshop Elements 11 did Green Screen" and I was told "Yes". They even show it on the packaged version as I saw it in Fry's this morning. But there is no mention of this in the 'features' section on their website. Someone is playing games.
I then purposely purchased an upgrade to my version 10 to 11 to do green screens and feel I've now wasted $85.
I was wondering why Green Screen Wizard was selling a plug-in for PS Elements 11 if Adobe already had it in there. I guess I know the answer to that one also.

How to fix iPad that has a green screen and lags when you try watching videos

How do you fix your iPad when it has a green screen and it lags when you try to watch videos, such as from YouTube?
I tried to watch YouTube on Safari but it does not work, and the app version of YouTube does not work either. When the video is playing, it will start to turn green, and it will lag.
Please, I would really appreciate it if you can help me, because I really want to watch videos again.
Thank you very much!

First thing to try is to reset your device. Press and hold the Home and Sleep buttons simultaneously ignoring the red slider should one appear until the Apple logo appears. Let go of the buttons and let the device restart. See if that fixes your problem.
If that doesn't help it is most likely a hardware failure. Make an appointment at an apple store to have the device examined by a technician.

For some reason, even though I have advanced features checked, the menu with green screen and all those isn't popping up when I drag the video on top of another one.

Hi
I would trash - iMovie pref file - and re-try - sounds like this got faulty.
• Delete iMovie pref. file. iMovie pref. file resides.
Mac Hard Disk (start-up HD) / Users / "Your account" / Library / Preferences
and is named. (one or more of these)
com.apple.iMovie.plist
com.apple.iMovie3.plist
com.apple.iMovie7.plist
com.apple.iMovie8.plist
com.apple.iMovie9.plist
com.apple.iMovieApp.plist
and find
com.apple.iApps.plist
While iMovie is NOT RUNNING - move this/these file/s out on to desk-top.
Now restart iMovie.
If You run Mac OS X.7 or more - then the Library in the User-account folder is invisibly and need to be set to be viewable. IT IS NOT in the Library on Root level (when opening MacintoshHD - first window = root level)
( It can be done like this: Open Terminal, then enter:
chflags nohidden ~/Library (exactly like this - space included)
Press return, then restart, and it will always be visible until the next major update, when you do the same thing again. )

Green screen and card

guys,
Ive done this before but i need to key out a green screen and green card what is the best way of doing this with best effect? Would motion or shake be better for this or should i stick with FCP?
Cheers
Dan

what you are probably seeing is compression artifacts causing edge chattering. the best, really only solution is to track a mask in to cut the hole rather then trying to key anything. of course if you could go back and reshoot and send the camera into something like a MXO2 and capture to ProRes / uncompressed would of been best, but nothing you can do now. the other problem is probably that the trackers aren't that good - something like mocha can eat thru this pretty easily. you may wind up doing this by hand.

Blue/Green Screen And Multiple Cameras?

Next week a number of us are demonstrating Blue/Green Screen filming and editing to members of our video club who are not familiar with the technique.
Originally the person who thought up the idea intended to have 3 groups of people filming a 2 minute script on a "station platform" a la "Brief Encounter".
So far, so good, but then the creator of the idea suggested we should shoot each scene with 2 or 3 cameras to make it look more professional.
I don't like complications when the aim is to demonstrate a technique, but somebody has suggested there will be a further drawback.
When we cut from one camera to another during editing, the angle of the "actors" will alter but the background will not!
This will create the equivalent of a jump-cut.
Has anyone done such a shoot, experienced this problem or found a (reasonably simple) solution?
My idea of a solution is to have one camera in a fixed position! But, then, I am lazy.

Hi Ian
You know me and my speculations (what You got without enough Know-How)
But I would try to first apply Green-screen effect to one Camera angle
at a time. Then I can get another background for Camera two etc.
Then save these as QT full quality .mov (or rather back to Camera and new tape
feel much safer this way) and re-import then and now prepare
for multi angle cutting. (By putting one Camera on each track. Minimizing size
to 25% and locate each to one separate corner)
Now playback and I will in Canvas see all Cameras in each corner and can by using
transparicy adjuts which one to be seen.
Then as a last action - upscale all to 100%
Done
But as You see this is me just speculating. I fell for FC-Pro and the MultiCam
function here. It's fantastic.

Can I use two different greens for green screening and keep one without it being keyed out?

I am using a green screen which is your standard light green fabric.
I am also wearing a bottle green cape.
I want to key out the standard green which is no problem. However it also takes out the bottle green on my cape.
Is there a way on either Premiere Pro or After Effects to ensure the bottle green stays as it is without being automatically keyed out?
Many thanks.

There's your answer, most likely. I can think of a few methods you might try, but they're going to be labor intensive, and likely involve some roto.
Most keyers have a threshold setting that determines what colors stay and which ones go. You could keep tweaking that setting in very small increments, and if you get lucky, it might discriminate between two green values.
You might be able to precomp in Ae and use the Change Color plug to shift one of them to a more contrasty green or different hue altogether and create a luma matte.
But, you failed green screen 101, and you gotta' go to detention.
robodog, you're being a bit harsh on Jimmy Simon. He said "Might be worth a reshoot...." I can't disagree. Depending on arahman's situation, a reshoot might be easier and quicker. You never know.

Green Screen and Electronics with shiny surfaces...

Not sure if the Lounge is the place to ask this one, but where I'm at the client doesn't have the budget to facilitate a pro making 3D models of the products they're advertising, but he wants them spinning. The products are needed with alpha. My idea was to try and put em on a spinning green pedistal on green screen with lights trying to get rid of green reflections. I'm probably on the wrong path here, so I'm asking for advice before embarking on what could be an epic fail(not that I still won't try it)...

This is a similar problem as "Removing Tint from Green Screen" (previous post). Any shiny surface will naturally reflect the background/sky etc. If you spin your objects against green that is what they will reflect. However when you replace the green with whatever background you choose the shiny objects will appear to reflect that new back, and that should look OK in many cases because that is what shiny objects do anyway. Of course the new back will not be distorted appropriately, specially notorious if the objects have curved surfaces but if the reflective areas are confined to a small part of the image this won't be a problem, and if you really want to deal with this then you can use "warp" to manipulate that part of the reflection.
Normally when you photograph a reflective product is better to create a "tent" that surrounds it and illuminate the object/product throught the material of the tent (usually thin white fabric or diffusion material). Even large objects like automoviles are photographed this way to emphasize their aereodynamic shape (so that it is not broken by unwanted reflections.
Good luck with your client
