Tutorial for Colour Correction and Green screen

Anyone know of any good tips to remove the green look from white hair? or any tutorials I can read for colour correction with green screen?
I filmed a getlemen who has white hair on a green screen. The colour of his hair picked up a slight tint of green and I need to remove it. Can anyone lend some sound advice.
Thanks

Your best chance is to study the manual carefully and to cycle through the chromakeying filters you have at your disposal. If you were using DV, you will probably need to purchase a far more capable keying application, one that compensates for DV's terrible chroma resolution.
The books on the shelves at Borders and Barnes/Noble for After Effects and FCP will help you get the most from your existing key filters. You will ned up stacking several copies of your footage with different key settings. Without preproduction, the proper lighting, a good camera and adequate tape format, managingr a good chromakey in post is very difficult.
google chromakey, too.

  • 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();

    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.

    Thanks, I will try that after a couple of days. I want to make sure that my iPhone is completely dry inside.
    Anyone who knows how long it may take for an iPhone to dry inside after 2-3sec in water? Its in a bag of rice.

  • Black and green screen after water

    Well I did this huge accident by dropping my iPhone 5 into the toilet, but it was only in there for 2sec. I dried the phone and it was still working, but after a while it turned itself off. As a reaction, I hurried starting it again to check if it still was working and it was. But after that, my friend told me to turn the phone off again as soon as possible.
    When I got home, I placed the iphone in a bag of rice without any air in it, and waited over 24 hours to check it.
    When I checked it(which I think I did too early)- it worked, and I was so happy! Everything, the sound was just fine, but after a while it didn't respond to my touches and suddenly the screen became black and green pixle-ish and grumsy, but I could still see something in the background.
    I placed it back into the rice, but this time on my bathroom floor in a bag, because it's warmer there.
    I don't dare take it out before I know that most of the water is gone, but at the same time I don't know what the problem with the screen was. Is it possible to fix it? I think I maybe can get some help from a friend, but it would be nice if anyone knew what i could do, or what the problem is.
    I also read about people who got problem with black and green screen on their iPads. Everyone who read the thread had hit their iPads on the backside of the iPad and it got normal screen again.

    You need to do more research before you make purchases like this. You've wasted your money. The ONLY officially unlocked iPhone model sold in the US is the GSM model, and that model is only sold by Apple. That's the model iPhone you should have purchased.
    Did you read & understand my initial post? Especially this part:
    The unlocking of the GSM portion is just for International travel in order to use local sims. You still have to pay Sprint for the use of their international GSM partner’s network on a “pay as you go basis”.

    Hello skdog I possibly think your ipod touch is black because it has not charged. If your dock is broken it might just mean the dock will be broken and so might be the USB port. You should see an Apple shop nearby and hand it over and see what they can do. I hope this information works!

  • Is there a video tutorial for using cyberduck and iweb?

    So, is there a video tutorial for using cyberduck and iweb to upload to a website? The written instructions on iweb are not specific enough.

    Might be worth posting that in the iWeb forum.

    Is there a recomended way to delete proxy and optimized clips once a project is completed and is ready for archive? also, can proxy and optimized clips be removed (to save space) once a project is ready for color correction and the original clips are used

    No, they are NOT the same as proxy or optimized.
    When you add a clip to your timeline and, say, apply an effect to it, or superimpose a title on the clip, FCP X has to make many calculations to determine what color each pixel of each frame should be. If a section of your timeline is not rendered, it has to do all these calculations every time you play those frames. A render file has the frames already "calculated", so it plays fast and smoothly.
    For simple compositions and a fast computer, you may avoid rendering completely - and you may also choose to only render the portions where playback stutters.
    Render files can be safely deleted. FCP X can recreate them if needed (either automatically if you have "background render" on, or on demand, when you select the "render" or "render all" commands).

    Does iPad 2 have green screen for iMovie?

    By green screen I assume you're refering to chroma keying?
    If so, then no.

  • ActionScript and Green screen

    How can I write Action Script to change out backgrounds for
    my flv with Green screen?
    I saw a swf demo running on Flash Player 9 where pushing a
    button let the user change out the background. I am guessing this
    was programmatically done with Action Script.
    How can I write ActionScript to do this? I have Flash 8.

  • Please answer once and for all the boot green screen

    I have searched everywhere for an answer since my issue.
    Relevant info:
    iPhone 3GS.
    iTunes version 10.7.0.21 (2012-09-12).
    Doesn't matter what system I have since this is related to an iPhone device.
    Fully charged battery before proceeding with the update.
    Updated the iOS 5.1.1 of the iPhone to iOS 6.0 through required update recommendation of iTunes.
    Never been abused, jailbroken, serviced or dropped. (never had issues until the update)
    Once completed the updated process of iTunes and iPhone was done with the internal installation, the iPhone rebooted with a green screen/hue and the apple logo was still original color "silver". It loaded up to the iPhone Configure screen still with green color screen/hue.
    I pressed on the power button for 5 seconds and slide "slide to power off" and the iPhone turned off. I waited about 15 seconds and pressed on the power button to turn the iPhone back on, hoping no more green screen/hue and the apple logo was still original color "silver" but returned to the original green screen/hue and the apple logo was still original color "silver".
    Failed!
    It still showed green screen/hue and the apple logo was still original color "silver" and booted to the iPhone Configure screen still with green color screen/hue.
    Remedies tried after searching the internet:
    Hard Restart/Reset.
    DFU Mode. (even tried a restore process with iTunes again *so much time wasted to obtain the iOS download again*
    Recovery Mode (even tried a restore process with iTunes again *so much time wasted to obtain the iOS download again*
    Recovery from Backup is denied because previous version was iOS 5.1.1 and iTunes refuses the process so (even tried a restore process with iTunes again *so much time wasted to obtain the iOS download again*
    Left the iPhone at the Configure screen until battery drained and then plugged it back into the USB port of system until it charged long enough for the iPhone to boot yet again green screen/hue and the apple logo was still original color "silver". It booted to the iPhone Configure screen which is still the green screen/hue and I left it charging until battery icon top right showed full.
    Now, can someone give a straight answer while staying on this topic about this issue, please?
    *I can understand if the apple logo was green then it could be a screen issue but it is not the case.
    All help is greatly appreciated even if you took the time to read all of this but did not answer.
    Thank you!

    halodev:
    I made a CF/Flex site based on the Flexstore sample app,
    using a database instead of XML as the data source; in case you
    want to see it:
    http://www.timos.com/dg/flex/DilemmaGames.html
    At first I had troubles similar to what you describe;
    initially, part of the problem was that my hosting company had not
    yet upgraded to CF 7.02. One other thing I had to correct: when you
    upload to your server, upload the entire ‘bin’ (or
    whatever your output folder is) minus the debug SWF.
    If it would help with other issues, contact me and I will be
    glad to make my project code available to you. Good luck.

  • Video card for HD and green screen

    I use a windows XP64 based machine with a quad core I7 920 processor and 12 gigs of RAM with nVidia 260 card. I use CS3. Right now I am having severe crash issues in Premeire CS3.
    I do HD 1080i video editing with up to 4 layers of green screen. I currently use Adobe AE Keylight2 for my greenscreen work. I bring the files into Premeire with "Dynamic Link". I crash, and crash, and crash. What is my best option to prevent crashing. A Quadro video card? which one? . Or, Matrox Max. My budget is somewhat limited. I can't get both. I want to upgrade to CS5 but need to fix this problem, now.
    Sincere thanx to anyone who can help

    I appreciate the quick answer and am considering moving to Windows
    7 (64). What is the sad story about Matrox? What is the best way to speed
    up my rendering or processing without having to purchase another cpu? Thanx once again for your quick response. I render primarily to h.264
