Why don't green screen clips snap together in imovie 11?

I film hundreds of green screen videos per year. I used to use imovie09, and when dragging one green screen clip next to another they would snap together. Now that I upgraded to imovie 11, it no longer allows you to snap the clips together, you have the cut the background in between them. Is there anyway to get these green screen clips to snap together like they used to in imovie09?

Well, now I'm even more confused.  I exported my iMovie project from my Mac Book Pro to my iMac and it worked perfectly.   Then I exported the same project to my Mac Book Air and it worked fine.    But when I go back to my Mac Book Pro - green screen effect simply shows as black and non transparent.   So, I have a work around but am puzzled why my Mac Book Pro doesn't work.   All systems on updated version of Lion and all have latest version of iMovie '11.   My Mac Book Pro is a mid 2009 - 2.8 Core 2 Duo and curious if anyone else has experienced this.

  • Why is my Green Screen not working

    So when I am using the Green Screen effect in iMovie The Picture going over the Green Screen is only partialy there.
    Here is the screen:
    Here is the picture:
    Here is the result:

    Okay, the only thing that might be remotely related to this is there's a setting for Green Screen you could try. Depending on what footage is being placed over the background, you would need to record or put some footage at the end of the green screen clip so iMovie knows what color the background is. Then you would use the  Subtract last frame feature.
    1. Add the green-screen clip to your project
    2. Double-click the clip to bring up the Clip Inspector
    3. Go to Background settings and enable the Subtract Last frame optin and then click Done. iMovie uses the frame as a reference to remove more color.

  • Strange problem when editing green screen clips

    Hi all,
    I work as a technician in a High School.
    Recently I was doing some green screen work with a class, we were using 10 macbooks to edit. Out of the 10, 6 had this same problem;
    At some point after inserting the green screen clips and the background, the project part of the iMovie window stops displaying anything, iMovie acts like the clips are still there though (If I move the cursor over the now empty space, I still see a preview in the preview window). But nothing is visible and nothing can be moved or changed.
    Closing iMovie and reopening doesn't work, restarting the macbook doesn't work. The problem seems to be saved to the project file, if I open a new project, the new project is fine, but if I re-open the broken one, it's still broken. The only thing we could do was completely restart and delete the project file.
    I hope this makes sense, due to this problem half of the class couldn't finish their work. The same problem has also occurred to another student who was working with green screen in iMovie 09 on an iMac.

    Hi Ted,
    I've seen this issue before. One thing to remember is that iMovie has a live rendering feature, so sometimes during playback, the viewer does not always display correctly.
    I don't know if you tried taking the green screen clip out, then re-adding it.
    Also, trying to simply delete the preference file can fix the problem. Home folder>library>pref>imovie.plist
    delete that and see if the problem persists.
    Doing this will not effect any projects students have made in iMovie.

  • Using 2 green screen clips and need to resize as one

    I am using 2 green screen clips - one is a prop and the other shows kids.  I have successfully loaded both into the Premiere timeline.  I would like for the two to act as one so that I can resize them at the same time so I can zoom in on the kids.   How do I link/group/??? them so they can be resized at the same time.   Thanks in advance for any assistance.

    Thank you.   Nesting worked and allowed me to zoom in.

  • I need help using Ultra Key on a green screen clip.

    I am using Adobe Premiere Pro CC to edit a blue screen clip, however, once I apply the Ultra key to the clip, I notice that when I start to render (using Adobe Media Encorder CC), the top part of the green screen clip gets blocked (cut off) by the replacement background! I have tried different backgrounds but I keep getting the same chest-to-head level blocked off with the background. When I remove the Ultra Key and render the
    clip with it's green screen, then it renders just fine! BELOW IS A SCREEN SHOT OF MY PROBLEM.
    Help!!

  • 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.

  • How do I reposition an inserted green screen clip into a corner of the host clip

    Help needed on moving or repositioning an inserted green screen clip to a corner of a host clip for presentation purposes, any ideas ??? Thanks

    You can drag and drop a photo at any point (at any frame... 30 frames per second.) Make sure you go to iMovie Preferences and enable Advanced Tools. You can drop a photo, and a pop up menu will come up. Choose Cutaway from the menu.
    Further you can use drag and drop to select a range of frames, and then split the clip.
    For example, lets say I have a clip of 60 frames (or 2 seconds).
    I can drag so that the yellow border covers the first 30 frames. Then right-click/Split Clip. (Or EDIT/Split Clip.
    I then have two virtual clips in the project. (Note: the underlying clip in the Event has not changed).
    I recommend you watch the [Video Tutorials|http://www.apple.com/findouthow/movies>
    Or see [Ken Stone's Tutorial|http://www.kenstone.net/fcphomepage/imovie_09stone.html]
    Or take a look at the HELP files.

  • 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!

  • Why can't I add transitions to green screened clips?

    I have still images with green-screened video on top. Is there a way i could merge the two or add transitions to the video part? it looks choppy with the green-screened part cutting out right before the transition of the still. thanks!

    Hello, AmezLady.  
    Thank you for visiting Apple Support Communities.
    I understand that you are unable manually add transitions.  This sounds like you may have automatic transitions enabled.  Try disabling this to see if you can manually add them.

  • Why a bright green screen before movie plays on Front Row?

    Before I reinstalled Leopard the other day all .avi movie files on Front Row would play immediately on selection. Now, for a brief moment, the screen turns bright green before starting a number of the movies. Not all are affected. But those that are come from the same initial bit torrent source.

    It seems to be part of the file as it shows when playing direct on QuickTime. Interestingly there's no green screen when the same file is played on another computer. And it didn't happen on this computer before re-install. Also, when the same files are played in QuickTime the QT pane reduces in size to smallest possible in the first few seconds of playing. If I enter full screen, the pane size doesn't reduce.

  • Why is my Green Screen Image Overlaying Over The Video?

    So, at first, I thought it was the lighting, or my green screen wasn't unwrinkled enough.  I'd made some other videos in the past without any problem, so, figured, it was fine.  Instead I get this
    What's happening, what can I do to fix it, and how do I start getting the software working right?  Thank You!

    looks for me, that poor lil' iMovie interprets the blue gradient at some values as 'green'.
    or vice versa
    The consumer tool iMovie offers, for convenience, no manual calibration of a color-key ... just auto-mode.
    Try with another replacement, for a start in red…

  • How to fix green screen blotches on teeth in imovie 10.0.7

    There are green blotches on the individual's teeth from the green screen used.  I need to know how to fix in imovie 10.0.7.

    "Did you have spinach for dinner?" ... SCNR!
    And such a nice smile, 'priceless' and most probably not to be re-done, right?
    sorry, to say, but that reaches the limits of lil' iMovie.
    You can not manually adjust the color-key in iMovie, as you can do in FCPX, nor does it offer any 'masking' features as Motion would...
    .. FCPX offers a 30d free and fully functional (no watermarks etc) trial ... but then you have to learn how to handle color-key in that pro app ... which is not a beginners task ...

  • 'Green Screen' Special Effects with iSight & iMovie?

    I need to record a short (30 - second) movie of just me talking. I thought I would record it with my iSight camera & Quicktime.
    If I use a green screen. . .can I swap in a different background in iMovie? If I can, does anyone have a good idea for a home-made green screen? (thought maybe I would just go to the art store and get a piece of green posterboard unless anyone has a better idea)
    TIA,
    Larry

    Hello Larry,
    "Green screen" recording is a function that is built into my Sony camcorders. Sony calls it "superimposing." Because it is easy to use the built-in function, I use my camcorders for all my superimposed video work.
    You can read about how it works on a Sony camcorder in pages 118 through 120 of this Operating Instructions manual. If you have a camcorder, yours may have the function, too, although it might have a different name if your camcorder is not a Sony.
    I do not know how to do with in QuickTime Pro. If you get no better answer here and cannot find the answers in the QT Pro Tutorial or Help pages, try searching or posting this question in the QuickTime for Mac OS Forum.
