Green screen replacement appears as watermark only

Hello all,
I am using iMovie 10 on my MacBook Pro OS X 10.9.4.
Trying to use the green screen option to replace the background of some home videos (shot with a Canon DSL)
but the background does not get replaced totally and appears as a watermark. This shows a bit of both backgrounds but everything
is blurred. I have tried trouble shooting by reading posts with similar problems as well as watched videos that show how to use this option
properly (i.e. dragging the background on top not over the video) but have been unsuccessful.
The post most similar to mine is by JakeTheSnake01 on Aug 29, 2013, 10.58am.
Sadly no one answered his post.
Please assist in any way. Many thanks.

For anyone interested: I deleted the movies on the 2G and reinstalled them using my other computer which uses Windows XP and ITunes 8. The green screen no longer appears when I play the movies. They were first installed with my computer that uses Vista. ITunes 8 is acting funny on the Vista machine. If I click on a link it will not go to the page until the pointer is removed from the link. I will reinstall ITunes and see if that helps. Anyway, I hope this post makes sense!

Correcting the Green screen tint appearing while loading images to the screen?

.... the Infamous Green tint that invades the screen, is still there on a whole lot of images - not all, a problem which occurs while images are loading to the screen for viewing. And it's on both the iMac whee it started, and the Macbook.
It was a problem that resulted from an Aperture update last year I think. Any clues?
Thanks,
Raphael

Today, after a year of trying to get rid of thei problem, an Aperture "Craetive" at the Apple store found a way to correct it after contemplating it for about 15 seconds.
Here is the remedy:
To get rid of it, select image(s), go to Photo in the menu bar, hold down Option key, click on Generate Preview in the drop down menu. Wait for it to finish processing - a few seconds. Done.

How to use Green Screen option?

Sorry this is such a general question, but I have very limited internet access here at work (can't even access Google) and I would like to figure this out before I leave for the day so I can grab what I need on the way home.
We are making weekly comical "newscast" type videos, and we have been using PhotoBooth to make it look like we are in a news room.
I would like to stop using PhotoBooth (due to the obvious extreme limitations in video/audio quality) and use the green screen option in iMovie 09.
Would anybody be so kind as to give a brief couple of paragraphs on the best way to accomplish this?
I have seen the option pop up when inserting a clip on top of another, but which one is the footage/image to replace the green area... the original clip or the overlayed clip?
And is there a specific shade/type of green that works best? Or can I just pick up a dozen yards of general "crayola" green fabric to cover a wall?

I have tried but haven't had much luck. Although I am having a problem with Snow Leopard and iMovie right now. That may be affecting my success. Here are the instructions out of iMovie help.
To use green-screen effects to superimpose video:
Record video in front of a solid green backdrop, and then import it into iMovie.
When you record, for best results do the following:
Use a pure (highly saturated) color of green for the backdrop.
The best color of green to use is often called “chroma key green” in paint and cloth.
Make sure the subject doesn’t have any green clothing, and don’t include anything green in the shot, other than the backdrop.
If possible, use multiple lighting sources to eliminate shadows on the subject being recorded.
Include a moment at the end of the recording with the subject out of the frame. This indicates to iMovie what should be left out when the video is superimposed.
Choose iMovie > Preferences, click General, and then make sure Show Advanced Tools is selected.
In the Event Browser, select video that you recorded in front of the green backdrop.
Drag the selection directly over a clip in your project (video, solid color, or animated background clip), and release the mouse button when the cursor displays a green plus sign .
Choose Green Screen from the list of options that appears.
The green-screen clip appears with a green border around it above the video clip in your project. You can drag it to a different spot to reposition it, or drag the ends to lengthen or shorten it.
To more effectively mask areas of the green-screen clip, select the clip in your project, in the viewer click Cropped, and then drag the handles at the top of the viewer to more tightly enclose the subject of the video.
Anything outside the highlighted area in the green-screen clip is removed from the picture. Be sure not to crop out areas that the subject moves into at any point during the green-screen clip.
To produce a better-quality effect, double-click the green-screen clip in your project to open the inspector, then select “Subtract last frame.” iMovie uses information in the last frame to determine what to subtract from the finished clip.
Selecting “Subtract last frame” works only if you included a moment at the end of the green-screen footage with the subject completely out of the frame.
To watch the clip, click the Play Clip button in the viewer.

Camera video preview - Random crashes and green screens

Hello everyone,
I am currently working on a Windows Phone 8.1 app and I need to preview video from the phone's back camera. For quite some time I've been struggling with random crashes and green screens. When these green screens appear, all camera apps become affected and
the device needs to be restarted. Occasionally the phone freezes and only recovers after battery removal. I test the app on my Lumia 620.
After some web search, I found references to the same problem by many users/developers of different apps. I'm really frustrated as I've tried many possible solutions with no avail.
Here is part of my code:
//in App.xaml.cs:
MediaCaptureInitializationSettings settings;
public static MediaCapture captureMgr;
public static bool UnableToInitializeCamera = false;
public async Task InitializeVideoCapture()
DeviceInformation backWebcam = await GetCameraDeviceInfoAsync(Windows.Devices.Enumeration.Panel.Back);
if(captureMgr!=null) captureMgr.Dispose();
captureMgr = new MediaCapture();
settings = new MediaCaptureInitializationSettings();
settings.StreamingCaptureMode = StreamingCaptureMode.Video;
settings.PhotoCaptureSource = PhotoCaptureSource.VideoPreview;
settings.AudioDeviceId = "";
if (backWebcam != null)
settings.VideoDeviceId = backWebcam.Id;
else
var _messageDialog = new MessageDialog("Back panel camera not found");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
try
await captureMgr.InitializeAsync(settings);
captureMgr.SetPreviewRotation(VideoRotation.Clockwise90Degrees);
UnableToInitializeCamera = false;
catch
UnableToInitializeCamera = true;
Debug.WriteLine("HANDLED EXCEPTION: camera could not be initialized");
var _messageDialog = new MessageDialog("Unable to initialize camera");
_messageDialog.Commands.Add(new UICommand("OK"));
_messageDialog.ShowAsync();
protected override async void OnLaunched(LaunchActivatedEventArgs e)
//.... other app initialization code
await InitializeVideoCapture();
Window.Current.Activate();
private async void OnResuming(object sender, object e)
AppIsResuming = true;
FinishedCameraInitialize = false;
await Task.Delay(TimeSpan.FromSeconds(0.5));//this makes crashes less frequent
await InitializeVideoCapture();
FinishedCameraInitialize = true;
if(WasPreviewingCamera)
WasPreviewingCamera = false; //the following line allows time for SetupPage._captureElement to be assigned before video preview starts while (!SetupPage.CaptureElementSourceAssigned) await Task.Delay(TimeSpan.FromMilliseconds(1));
SetupPage.CaptureElementSourceAssigned = false;
try
Debug.WriteLine("trying to restart video preview");
await captureMgr.StartPreviewAsync();
SetupPage.PreviewingCamera = true;
catch
Debug.WriteLine("HANDLED EXCEPTION: unable to start previewing");
SetupPage.PreviewingCamera = false;
GC.Collect();
AppIsResuming = false;
private async void OnSuspending(object sender, SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
while (AppIsResuming) await Task.Delay(TimeSpan.FromMilliseconds(1));//prevents crash when app is suspended right after it is resumed
await CleanupCaptureResources();
TimeOfLastSuspend = DateTime.Now;
FinishedCameraInitialize = false;
GC.Collect();
deferral.Complete();
public async Task CleanupCaptureResources()
if (SetupPage.PreviewingCamera)
await captureMgr.StopPreviewAsync();
WasPreviewingCamera = true;
SetupPage.PreviewingCamera = false;
else WasPreviewingCamera = false;
if (captureMgr != null) captureMgr.Dispose();
//in SetupPage.xaml.cs
void OnSuspending(object sender, Windows.ApplicationModel.SuspendingEventArgs e)
var deferral = e.SuspendingOperation.GetDeferral();
_captureElement.Source = null;
CaptureElementSourceAssigned = false;
GC.Collect();
deferral.Complete();
private async void OnResuming(object sender, object e)
ProgressRing2.Visibility = Visibility.Visible;
ProgressRing2.IsActive = true;
while (!App.FinishedCameraInitialize) await Task.Delay(TimeSpan.FromMilliseconds(1));
App.FinishedCameraInitialize = false;
captureElement.Source = App.captureMgr;
CaptureElementSourceAssigned = true;
GC.Collect();
ProgressRing2.Visibility = Visibility.Collapsed;
ProgressRing2.IsActive = false;
Any help towards a solution will be greatly appreciated.
Thank you

I will also advice that you start by following the
Windows Store app sample.
Is this a Windows Phone app?
The crash/green screen only manifests itself when I suspend my app and switch to the default camera app (could be any other camera app perhaps). It happens roughly 1 out of 8 times. That's why I posted the suspension and resuming handlers, which I wrote
according to the msdn instructions.
I found
this page with a sample that demonstrates the MediaCapture API for Windows Phone. Some developers have reported problems similar as mine. Has Microsoft dealt with this issue?
I've spent quite a few weeks trying to investigate this problem, without actually knowing if it is my code that needs to be debugged. That's why I'm asking if other developers are facing similar problems.
Thank you
Edit: It seems that the crash/green screen can appear when suspending/switching to any app (regardless if it uses the camera or not). Also, all works fine when the app is running on the debugger.

Why is the green screen visible on the last frame before the next clip?

Hey guys!
Maybe I'm ******** but i m having trouble here. I have "key-ed" a bunch of clips and successfully removed the green screen from them. But when placed in the timeline, the green screen of the clip reappears for the single frame before a next clip starts.
I've re-rendered and chopped ends off but the green screen keeps appearing in the last frame of any keyed clip that is about to cut to a different clip.
Where am i going wrong?

Hey! I tried both suggestions but even the self contained quicktime file has the green screen frames popping up.
I just dont get it, it's infuriating!
I used "chroma keyer" effect on the clip, only enable "key on saturation", the green screen disappears, I place clip on V2 and image on V1. Image is then visible where the green screen was. All is well until the last frame before a next clip because on that ast frame the green screen appears again. Where am I going wrong? Please help!

I was making a movie on iMovie, and the green screen wasn't working.

I was making a movie on iMovie, and was trying to use the green screen to make a split screen. I pressed on the green screen button, but the second clip didn't play next to the first, and only the audio played. I tried agian with some different clips, and only some of them worked. This hasn't happened before! I was just wondering why this would be happening and what I should do? (I am using iMovie '09)

Hi
YOU need to - in iMovie - Turn on Advanced Tools !
top row menu - with an Apple top left ---> iMovie ---> down to preferences ---> Here select to turn on Advanced tools .
Now it will work when You drop a clip onto another IN a MOVIE PROJECT ! (can not be done in Event's)
Next problem I had - was to get right clip onto the other - what was the Background and What was the Green screen - BUT just test - You only got two ways to try out.

Help with green screen on videos

There must be some bug in the HP laptops that causes so many complaints about the green screen. I had to reinstall my system because there was some problem that my anti virus and malwarebytes couldn't fix. So, low and behold the old green screen on videos reappeared. I tried a former solution given to me by one of HP techs on here. I went to tools, internet options, advanced and then clicked on Use software rendering instead of GPU rendering. Wasn't working. So I download HP Support assistant. In the search I put Green screen on videos. The only thing that came up was to fix a video card. I don't have a video card. I looked at the suggestion on the forum to update Flash player. I got the message that Flash player is installed with 8.1 so not install for it. I realize a great deal of problems are caused by Microsoft negligent creation of 8.1 but hopefully the HP techs can do a better job of addressing this. BTW don'l look forward to updating to Windows 10 if you are paying for an extended warrenty. Microsoft say's if you upgrade to Windows 10 from Windows 8 or 8.1, you warrenty is invalidated.

Hi,
Please perform a clean install Flash Player first:

Green screen issues when playing videos in fb + youtube

at first i noticed a re-occurring problem when playing videos via facebook or youtube. A green screen randomly appeared now and then until i reset the laptop. I tried many things, including one suggestion to change quality option from 480p to 140p via settings option in youtube. It worked on some occasions, was able to view video as the green screen disappeared. Of course, as expected, image quality suffered. I contacted Lenovo to inform them of issues I was having with viewing videos, they advised it was a problem with the adobe software and that I should check to see if I have an updated version installed on my laptop. (currently running O/S windows 8.1 and IE 11), I downloaded chrome, fortunately, I am able to view videos in youtube properly even though they appear as a green screen in IE 11. Not so lucky with facebook however, green screens in IE when playing Facebook video uploads appear as black screens in chrome. I reset the laptop and everything appears to be running fine. Is this an adobe software issue? Lenovo seems to think so, Seeing as how others experience the same issue regardless of the make and model of laptop, they may be right.

Please work through the video troubleshooting guide.

IMovie 11 mini green screen

Matthew or another expert, are you out there?
I want to videotape my subject on green screen, and superimpose her on a map -- but I want her to be small, not the same size as the background I am superimposing upon. Is this possible in iMovie 11? Please respond!
Thanks,

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.

Green screen appearing when trying to play back videos

Hi everyone.
I tried to play some of my videos today and for some of my videos (I downloaded from Itunes a few months ago), a green screen appears and then it goes black and all I can hear is audio. Anyone have this problem and found a way to correct this? My only other option would be to repurchase these videos, which is something I don't want to do. Thanks in advance for your help!

with that one, try working through the following document:

Green Screen works - replace green screen clip - nothing....

iMovie 09 8.0.6. (821)
Seems like once I delete a green-screen clip from a background, I cannot replace it with another green screen clip.
I created the background clip. Created the green-screen clip by importing a Quicktime movie of an animation. Imported the movie. Dropped green on background - worked perfectly.
I deleted the green screen clip from above the background clip. Exited the project. Made a modification in the origin green-screen clip. Returned to the project Imported the modified Quicktime movie. Dropped it on the background. Got the + sign. Everything seemed okay. However. The green-screen does not appear.
As a test, I dropped it on a different clip in the same project - worked perfectly.
Seems like once I delete a green-screen clip from a background, I cannot replace it with another green screen clip.

It looks as though they used the keyed out torso as a track matte for the other footage.
