Can I make a DIY green screen or does it need to be an exact colour cloth?

I would like to try using the green screen effect in iMovie but as I do not own a specially made green screen background I wondered whether I can make one if I buy a large piece of green material from a dressmakers shop. Can i do this or does the shade of green need to be exact? Would it be better to just buy a proper green screen from a video equipment supplier and if so, what specification should it be?

The only thing to remember though is to have a lot of good even lighting facing the wall. If you use fabric it should also be pulled tight. Shadows from folds in cloth make darker spots of color on the screen and the software will not key (chromakey) out the darker spots. One thing that I have used in the past is a bright green table cloth. I got one from Party City (6'x9') for $3.50 two of those and you're good to go! I got a bright green snuggie for christmas that matches the color of my screen! Now I can do floating head effects. Have fun!

How can I fix my flashing white screen? Does it need repair?

I left my ipod touch to charge and when I went to get it I clicked on the home button and the screen was white. I googled about this white screen and I kept hearing about this "white screen of death", and saw alot of videos. Well how my iPod touch looks, well its not exactly white but rather is somewhat white as if its flashing white. I can vaguely see the ipod icons, and can play pandora or other apps but I can't see a clear screen because of the flashing white screen. I was wondering if maybe it has to do with internal things I need to get fixed like the lcd, or the digitizer. Is there anything I can do, or do I ttake it in to get it fixed? I tried clicking the home button and the power button at the same time but yes the apple icon appears but also the flashing white comes out. I dont know what to do.
Here are some pictures

Yes this iis how it looks when I reset it. http://i104.photobucket.com/albums/m199/wattsup_14/CAM01298.jpg

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

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.

Put my macbook pro to sleep. When I opened it, the desktop window is small and I can't resize it. All applications now run in the smaller size window. Can't make it fill the screen. Just switched from windows. Thank you.

Check to see if the resolution has been changed in System Preferences.

I have a version 1 iPad. I would like to be able to use my LCD projector to display content to my students. I have the dongle to attach to the projector, but can't make it work. The process DOES work with my friend's iPad 2. Any advice? Thanks!

Expanding on what deggie said, with an iPad 1 the app you're using must support video out. Only the iPad 2 can mirror the screen. The apps included with the iPad that output to external monitors are given here:

Can you use imovie's green screen feature to make things invisible?

Hi,
i have a GoPro, and am making a mount that will give me a 3rd person view while i snowboard.
Like this: https://s3.amazonaws.com/ksr/assets/000/333/633/7ac3cbc3da3b7b2c948f36e6018ea460 _large.png?1357825021 (but home made)
However, the tube will be in video, it would be great if i could edit it out...
I was hoping that i could paint the arm of the mount green, and use the green screen function to edit it out in post. like the skate boards in this video: http://www.youtube.com/watch?v=654lUYIhYk0
I have looked around online, and it seems that the green screen function in iMovie sems limited to just backgrounds...
Any advice?

Excuse the delay in replying...
Excellent! - thanks for that xnav
It work even with the delay set to 0.0 on the iPhone Simulator, but not sure about on an iPhone though.
I think I need to read up about @selector and the performSelector instance method.
I found today another possible solution (but have not tried it out though):

Can't figure out why green screen is pixelating!

I had terrible problems with square pixelating on my production.
any ideas on what caused this... we played with saturations all day with no effect. I did have a empty green "last frame". It seemed nothing we could do would help!
I filmed with a Sony DCR-SR68 HandyCam in the highest quality and the background I chose from a Free Use source for greenscreen back grounds online.
I hope you can give me some insight here...every tutorial i have watched made green screen in iMovie look very simple... and yet we could not figure out why this pixelation was occurring!
reasons i wondered about:
green screen is too light?
...however i have seen screens look a lot worse and work
something to do with how i am filming?
...i realized that "facial recognition" was turned on which caused the camera shot
to move a little as i moved
am i too close to screen?
...i was about a foot away from screen (but no shadows) and camera was about a yard in front of
me
if anyone wants same rendering or screen shots let me know and I can email some!
Let me know what you think and if you need anymore info!
Thanks in advance for all your help!

Earl...
I know you said you reformatted the drive but just in case, how much free space on the startup disk?
Right or control click the MacintoshHD icon. Click Get Info. In the Get Info window you will see Capacity and Available. Make sure you have a minimum of 15% free disk space.
fresh install of 10.4.7
Most recent version for Tiger is v10.4.11. Have you tried updating the software from the Apple menu > Software Update?

Hi,
Pic first
Handle = Screen Name.
Name = Your Details as per your My Card (Head and Shoulders iCon) in the Address Book - Or the User that is Logged in to the Mac.
Each Buddy List will show the same Name but a different Handle based on the Screen Name for that Buddy List.
If you only have one Buddy List (other than the Bonjour One) and you Delete it then the Buddy List Disappears - Problem Solved. (Presumably you are re-adding a New Screen Name ?)
Pic of the Minus Button I am talking about.
Multiple Buddy List are created by adding more then One Screen Name to the Accounts List (Previous Pic)
I am a little confused where you were when you did this:-
I tried clicking on the minus sign in the list of users to delete the account and tried signing up for a new iChat account using my AIM screen name/password;
"List of Users" sounds like you were in System Preferences > Accounts.
You can "Delete" an Account here. It is not actually removed from the Users Folder (Hard Drive/Users) but is locked in a way that no-one has access and they are Removed from the Login Screen when the Mac Starts Up.
DO NOT DELETE ANY CLOSED ACCOUNT FOLDER In the Users Folder.
But if you use the same Screen Name in another Mac User Account the same Handle will appear.
You will see my GoogleTalk Account is headed "GoogleTalk" and my AIM Account as "Main AIM Account" These are set in the Description field in the iChat > Preferences > Accounts.
The Default if you have one account that logs into AIM is for it to read "AIM Buddy List"
Similar for one Jabber Account.
With more accounts of any one type they take on the info in the Description Field - which itself by default is the Screen Name.
Are you trying to create a New Mac User Account and use the same AIM Screen Name there ?
Are you trying to just change AIM Screen Names ?

Can anyone help with a Green Screen Walk Out with FLV

I have seen a number of sites that use an interactive video walking out over the website. I have final cut and can create an .flv with a green screen. The problem is I do not know how to create the player for the overlay. I think I may need CS3 but I was hoping someone might have a work around.
Here is an example: www.thinkvacuums.com
I was able to take the source and put it into iweb as a test but I can't access the files to swap out my video.
If anyone knows how to do this with Iweb and not using CS3 please let me know.
Thanks,
Will

Green screen match move solution needed

I've been asked to create a video version of a live performance which features musicans performing in front of a video backdrop of moving imagery. Their backdrop is not 16x9 and we don't really want to see any kind of frame around the projection, so I'm thinking perhaps we should simply green screen the talent and key the imagery in post to fill the background. This would make it easier to sync the imagery between shots and elimates the need to color-correct the video projection, but it introduces the problem of matching the background to the camera angle. If we were to use only stationary shots, I'd be inclined to think we might be able to simply approximate the geometry for each shot, as the imagery has no specific spatial relationship to the performers - it's simply the background. All we're concerned with is approximating the angle of the imagery so as not to jar the viewer when we cut between camera angles. However, it's likely that we'll want to incorporate some camera movement as well, which of course introduces a whole other set of complications. It appears to me that match move software is really designed to facilitate 3D object tracking and seems like extreme overkill for this project, particulary as the cost and complexity of this software is well beyond our budget. Is there another approach we should be considering?

Thanks, I had hoped that the new camera tracker in AE would provide a simpler solution, but after looking at it in greater detail I can see that the level of complexity it introduces to each shot along with the time required to pull consistenly clean keys from a variety of angles would make the production of what is essentially an 80-minute music video a completely unsuitable option. Now looking for a rear-projection solution...

When firefox opens on my 22 inch moniter, it only shows up in the middle of my moniter and not the entire moniter. How can I make firefox fill my screen?

It shows a white background on all the moniter, but the actual images are shown in the center of the moniter with 5 inches of white screen on both sides of the image. It is also to small of print.

Obviously, I have told the computer to open a folder at startup
Mac OS has had the behavior that if you have a window open at shutdown, it will automatically have that window open at startup - for your convencience. If you do not want that, there is no need to have a folder open at startup and you can easily avoid that. As mende1 said, make sure you quit (that is Command + Q or File > Quit) all applications before shutdown. And, close all open Finder windows by pressing the little red button in the upper left corner. Also check your System Preferences > General > Close all windows when quitting an application.

Does your email site have a print button to format the page for printing? That often gives the best results.
If this just started with Firefox 4, it could be related to a change in how strict Firefox is about a page's HTML code. To see whether this problem is caused by the new HTML5 parser, you can turn it off like this:
(1) In a new tab, type or paste '''about:config''' in the address bar and press Enter. Click the button promising to be careful.
(2) In the filter box, type or paste '''html5''' and pause while the list is filtered
(3) Double-click '''html5.parser.enable''' to toggle it to false (it should turn bold).
Then return to your mail site, reload the page, and test again. (Print Preview might be sufficient for testing.)
Does that make any difference? If so, the site might not yet be fully compatible with Firefox 4 -- or you have found a bug in Firefox.

Can I make a DIY green screen or does it need to be an exact colour cloth?
