Chroma keying / motion key

Hi guys.
I am working on another music video for a freind. I have filmed her singing the track via mini dv with the camera on a sturdy and non moving tripod.
I would like to add some 'ghost' type effects - ie have the singer dancing around with herself.
I know I can do this just by overlaying the shots in FCE and adjusting the transparency -
but - a freind of mine who has used FC for years was telling me that their is a way to extract 'just the motion' from a clip leaving the moving dancer dancing, but cancelling out the background image. Unfortunatly my freind is somewhere in Germany, and I am in New Zealand - so I was wondering if anyone here knows what I am talking about and could offer me any suggestions.
Plus any tips of how to make 'spooky' ghost images would be appreciated too!
I have a clip which just shows the background scene (in this case a tree), and also three takes with the singer singing along to her song.I thought their might be a way to cancel out the image of the tree - like I could if I put up a green screen - but without having a green screen - kinda like those sound cancelling headphones which play sound of an oposite phase which cancels out background sound......
cheers for any help

thanks heaps tom! I think that is exactly what I am after
and ghosting effects that sounds cool - I'll have a play

  • Is it possible to chroma key a moving laptop/phone screen in Motion 5?

    Hi, I recently downloaded Motion 5, and I've been experimenting with it. What I'd like to know is if it's possible to chroma key the screen of a phone (the screen will be green.) I've managed to chroma key out the green, and it works perfectly, except I don't know how to make the "screen" follow the phone or stay on the phone if the camera moves. Also, is it possible to make the "screen" dynamically grow/shrink as the camera zooms in/out. Is such a thing even possible with Motion?
    Thanks in advance!

    a color-key isn't needed for such an effect…
    What you like to accomplish is something like that:

    This is called 4-corner motion tracking, advice in the Manual

  • Chroma keying - Motion 5 vs Adobe: which is better?

    Has anyone compared chroma keying with Motion 5 vs Adobe Premiere Pro cs5.5 or even Afer Effects cs5.5? Are the advanced features in M5 just as good as ultra keyer in Premiere Pro or Key light in AFter Effects?
    I am looking to do vids with lots of green screen shoots. I am undecided if I should purchase FCPX +Motion 5 or the Adobe Production Premium (including Premiere Pro adn After Effects).

    Haven't tried it personally yet, but Alex Lindsay, who's company makes the super high-end keyer Conduit, says that Motion 5's keyer is amazing and they are having to rethink their product because of it.
    So, it sounds like it's at least worth a $50 experiment to test it out. You can use it with FCPX or Premier.

  • Real-Time Chroma-Key Motion

    So I have an idea brewing in my head and am seeing if it has any possibility of working.
    I was wondering if it would be possible to be take in video and have a motion element (a pre-built, constant element) move around the AE composition in relation to an object moving around the real world camera composition of the video - using a chroma key method of say a green screened body part or paper airplane waving around.
    Far fetched maybe?
    Thanks for any response

    Adolfo: First of all thank you for your response! I appreciate it so much.
    I have gone and looked up Matchmoving, but that is not quite what I was looking for. On the Bonjour site (2d3 company) I did find another product, "TacitView" that seems more like what I need. It tracks movement in video.
    Hopefully I can better explain myself this time around :)
    I want to set up an unmoving camera, have the movement in the video be tracked, and have a graphic map itself to that movement.
    A scenario example: A camera is at the end of a hallway. It is recording and I walk into its view. Software detects my movement. A graphic I created then moves side to side as I do.
    My ultimate goal was to have that graphic then be projected/displayed back out so It creates a mirror effect. Except instead of your reflection you would see a graphic element moving along with you.
    I'm pretty sure after effects wouldn't even be the software here, and it will probably be multiple software's routed together, but it's the only one I know that might even touch this idea.
    Thanks for any help!

  • Chroma key after fixing movement in motion

    I created baseballs flying around in fcp with a sky background. The moves were jerky so I sent to motion and smoothed the movement. I brought it back to FCP applied the chroma keyer to remove the green screen. When I do that the green goes away but the background goes black. Why does the sky layer below disappear when I turn on the chroma keyer?
    Also why doesnt motion have croma keyer. Color keyer does not work as well as chroma key.

    You created them? You mean you edited together some video clips of baseballs? Or you mean you animated a graphic of a baseball? Big difference. Big difference in how we will advise you to move along.
    -It is a video of rotating baseball against a green color animated to look like being thrown.-
    dougleax wrote:

    You should only process the original media. I cannot tell from this statement if you know how stabilization actually works. If you are chromakeying the stabilized video clip, you may want to perform additional work on it. For instance, is the shutter speed high enough to reduce image blur? Is the footage interlaced?
    -No stabilization used. The movements is FCP were Jerky between keyframes. FCP motion is hard to control. Thats why we use Motion...to smooth the movement..correct?
    dougleax wrote:
    I brought it back to FCP applied the chroma keyer to remove the green screen.
    Ah. So your original statement about creation in FCP was misleading or incompletely descriptive. Is this a still image of a baseball against green? Or are these video clips of off screen hands tossing baseballs across the screen? If they're video, don't stabilize them, reshoot it with the camera on a tripod.
    -I brought it back to FCP. When I did the original Chroma Keyer was lost.-

    Then you're not using the keyer properly. You may be looking at the matte or the processed key and not the output or final image.
    -turn on keyer the green goes away and the sky image appears where there was green, but the rest of the background goes black.-

    The blue/green keyer in Motion is fabulous. Why are you using the color keyer?
    -From what I see in tutorials, people suggest to use Primatte RT. In FCP Color keyer has more control over how it affects highlights and shadows, Hue range.-
    Motion has 5 keying options. FCP has about 10. I just like the was Chroma keyer works for my purposes.

  • Does Motion 5 Chroma Key compare with Premiere Pro or After Effects?

    Does the Chroma Key in Motion 5 work as good as Premiere Pro or After Effects cs5.5? I am looking to do lots of green screen work.

    Thanks! Reason I am asking is that I am undecided on going with FCPX or PP/AE. I will be doing lots of green screen (presentation style mostly). I checked out Phyx, it looks really good. I just don't know if I want to spend that extra money.

  • ¿How do you change the time of all images and do the chroma key effect in ¡Movie 10.0.2?

    I know it's a simple question, but i had ¡Movie '08 and I bought the latest version, and it's really different, so I don't know, if i have like 150 photos (it's an stop-motion) how can I put the same duration? And do the chroma key effect? And I don't know why, all the images have the Ken Burns effect and I don't know how to quit it. Thanks for the help!
    Marcireca

    I solved the same time problem, but now the problem is that when i use the chroma key it automatic uses the blue screen effect, not the gren (wich I want). Please help! Thanks!

  • FCPX 10.1 Chroma Key Strength Slider Crash

    Hello fellow users
    I will apologize in advance as I am just the IT guy and am not well versed in editing lingo, but here it goes. My chief editor came to me with a problem that he has had since the first FCPX. I will post the crash report below, but I will tell you that I don't think hardware is an issue. I have reproduced this crash on everything from iMac and Mac Minis to Macbook Pros new and old. If it matters they are all rocking NVIDIA cards. We use a green screen chroma key and everything works swimingly until you attempt to adjust the slider for Strength. The keying effects are made in motion and executed in Final Cut. Upon attempting to adjust the slider, FCPX hangs for roughly 10 seconds and then ultimately crashes.
    Here is everything I have tried (in no particular order, but I assure you I have been scanning forums for days and troubleshooting has been executed in the correct order)
    1. Complete reinstall of Mavericks, also attempted on Mountain Lion
    2. Complete removal and reinstall of FCPX, Motion, and Compressor (yes I used that FCP remover tool one time too)
    3 Trashed preferences, saved application states, layouts, etc.
    4. Rebuilt Key effects from scratch
    5. Installed CUDA Drivers
    6. Removed and/or reinstalled plugins (Sony XDCAM)
    7. Used Disk Warrior to rebuild directory.
    8. Repaired Disk Permissions
    9. Checked the Activity Monitor during crash for other CPU/GPU intensive processes
    10. Deleted used and unused render files in FCPX
    11. Set to optimize imported media (problem originally existed without it checked, checking did not fix, but I digress)
    Below is the crash log for the event on the Macbook Pro that I use. I am basically looking for a fix or thoughts on anything my editors or myself may not have tried. Thanks for the help.

    Thanks I wasn't sure about the CUDA/OpenCL thing. Graphics terminology I am slowly learning about basically through the advent of crypto.
    In the computers that are used primarily for editing we have NVIDIA GeForce GTX 680MX with 2 GB VRAM. They have 32 GB RAM. I just got hired on but when the op manager bought these (Late 2012) he basically fully speced them out. 1 TB Fusion Drive (which I would totally get if they are causing the issue) and the 3.4 GHz i7.
    I just got in but I have the editor trying things out with my USB 3.0 Wallet drive. Really I am just looking for any improvement in efficiency as what I really want to do in the long term is pull out our old CAT5 cables, wire the building for 10 GBe, and set up an XTarget SAN.
    Finally, in terms of video codecs we are using Sony XDCAM HD422, which I assume is ProRes. We are also working with graphics and videos that are not the same such as videos downloaded from the internet if that makes a difference. However the chroma key effect is only being placed on the footage from the camera.

  • Best chroma key plugin for FCP7???

    I have Final Cut Pro 7 and Motion and would like to know what is the best chroma key plugin.
    I've heard of DV Matte, Adobe Keylight, and Red Giant's Primatte Keyer Pro, but have no idea which one to get. Personally, I would prefer to stay in the Final Cut/Motion environment as I am more familiar with their interface than with After Effects.
    Thanks in advance for any advice,
    - Nick

    there is a very good keyer in Motion; its free and you have it
    the best; well thats Ultimatte:

    Hallo everyone,
    Does anybody know why when I try to apply a croma key filter on Motion the image I get is like this ?

    Is there any option to set in Motion Prefs? Thank you

    DV has a basic problem when trying to do a chroma key - that is it achieves its compression in the color channel - its color information is 1/4th that of its luminance resolution.
    This is a quickie - using Conduit to key in Motion:
    You can find out about Conduit here:
    http://www.dvgarage.com/prod/prod.php?prod=conduit15&sub=samples
    Check out the movie on keying DV for some insight into the limitations of keying DV. dvGarage also sells dvMatteBlast that handles all of this - a very nice product and they have a test version you can try...

  • How to protect an area in a chroma key?

    Hi Folks,
    I'm having a bit of a problem performing a key on a section of footage. There's an article in the foreground that unfortunately is the color of the greenscreen (bluescreen actually). Is there any way to 'protect' that area so that the chroma key filter doesn't affect it? The closest solution I've come up with is to duplicate the section of footage and move the copy to the next higher video track, then use a shape mask to frame the small section that is problematic. This works for the most part except that during the cross dissolve at the beginning and end of the clip. During the dissolve you can clearly see the shape of the mask as it doesn't 'dissolve' at the same rate as the dissolve on the underlying original clip.
    I would imagine that there has to be a simpler way to accomplish this, but it's eluding me.
    Thanks,
    Chris

    If you have to dissolve between composites, which is what you're creating with holdout and edge mattes and keys, you have to merge all the layers into one and then you can apply those transitions. You need to either key all the video you're using, export animation + which will maintain the alpha and edit into your sequence or export selects to Motion with sufficient handles for your dissolves and then import those Motion projects back into FCP.
    You could create sequences of any selects, do the key in FCP with your mattes, import those sequences into your master which would also take care of any dissolves. However, Motion has a superior keyer and matte tools over FCP.
    At any rate, this involves some organizational strategy over just applying a keyer to a layer in FCP.

  • Chroma keying and color correction on same clip

    I have an image, with some people shot on a green chroma key background. I want to key it on another image, and desaturate it, except the yellow color.
    I have no problem keying out the green. I can also desaturate the image, with the deaturate filter, but if I apply the color corrector, and work with it to only keep the yellow color in the image, then my chroma keying is lost.
    It kinda turns of the chroma key completely.
    What is the easiest way to chroma key out the green of an image and desaturate everything except the yellow color of the image?
    I have Final Cut Studio, so if it's easier to do it in Motion, then I'll do that...?
    It's shot on HDV, so it's already a little tricky to key out the green perfectly.
    thanks for your help.

    After you key the image, export it as a self contained QT movie. Then re-import it, and color correct it to suit your needs.

  • Final Cut 7 Chroma Keying

    I'm using green screen files that were mpeg-2 muxed converted to quicktime files using ffmpegX. I key them with a white background, but when I export to a Quicktime movie I lose quality and there is an ugly, pixelated white line around the subject. What codec should I export with? I've tried ProRes (LT) 60p and the HDV-1080i50 codec just to fool around, and in those the subject looks better but the background becomes pixelated and grey instead of white. It was shot on a P2 Panasonic, the original size of the media was 1920x1080, 75,000 bit rate. I'm sure the conversion of mpeg-2 to mp4 took the quality down a bit, but it seems quite bad now. Codec suggestions? Thanks.

    If you shot with Panasonic P2 (DVCPRO HD or AVCintra? Guessing AVCI) then why do you think they are MPEG-2 compressed (they are not), and why did you use ffmpegX to convert them?
    FCP 7 imports AVCIntra as ProRes directly via Log and Transfer. And it is best to use ProRes 422, and not LT, if you intend to Chroma Key. NEVER go to HDV...that's just horrible to do to nice AVCIntra footage.
    What did you use to Chroma Key? You don't specify.
    WHite background? Not green or blue? That isn't a keyable color. VERY problematic. You shoot with a blue or green screen if you intend to key. Not white.
    Again...AVCintra isn't MPEG 2...WHY did you convert to mp4? Sorry, but do you know what the heck you are doing? Doesn't sound like do.
    1) Shoot AVCintra P2. If you want to chroma key...CHROMA means COLOR. White is luma. And the two professionally accepted ways of chroma keying are green and blue. Anything else an you have issues.
    2) Log and trasnfer that to ProRes 422. Not HDV, Not mp4. Do not use outside software. The P2 workflow in FCP is the easiest tapeless workflow, as it was the first one.
    3) Key out the color with the built in Primatte keyer, or with good third party options (DV Matte Pro, Motion, After Effects and Keylight...)
    4) Comp in your background.
    5) Export to your delivery format.

  • AVCHD Sony footage has lines in chroma key in FCP

    My footage shot on with Sony Nex-fs700 will not chroma key with placing blue vertical lines in the final key. The line appear only after I render.  My sequence settings match my footage.   Can anybody help. 
    Stinson

    I shot in 1080 24p FX and I set the sequence  to 24 fps and I was getting the vertical lines, flicker and lag in the image with any quick moments.  So I created a new sequence and placed a test clip on the timeline and FCP asked if I wanted match my clip to the sequnce and I said no.  I applied the color smoothing 4:2:2  and chroma key filters and  played the clip and it was fine but still with the vertical lines.  I then removed the color smothing 4:2:2 filter and  no vertical lines.  Still might send you a short clip just for kicks.
    Yes I have  After Effects and Motion and I will give them a try when I finish this project.

  • Reflecmedia Chroma Key question

    Any one out there use the Reflecmedia Chroma Key system out there?
    I wanted to know how easy it is to use with final cut or motion.
    Cheers!

    What I need to know is, do you film with the Reflecmedia system then do all the knockout work within FCP or Motion or even AE which I use anyway. <</div>
    Keylight is a fabulous chromakeyer, for sure. You're going to be shooting and posting the same way. You will just get a remarkably superior key source from the retroreflective screen. It's really coo from the demos I've seen, absolutely solid, even, and clean. But I need to say once again, I have no personal experience with the units. I have seen them demo'd at NAB, very fun. No one in my market are has one.
    From what i can read it just talks about live keying, which i wont be doing. I want to film it take it away and edit it in my Mac. < </div>
    Live keying with Reflec's tools is a major selling point for them at conferences but obviously you need a live processing system which the Macintosh does not offer out of the box.

  • Chroma Key ideas

    Hi everyone. I have been using FCP for some time now to chroma key with varied success. All good, but have just seen SERIOUSMAGIC ULTRA2 in action...so much quicker and easier to get a good key with.....ONE BIG PROBLEM sadly ony available for PC. Having seen it in use there must be something better for the mac than the way you key in FCP. Anyone used anything better/ simpler ?

    Editmojo is on target. DV Garage has a great plug-in for Motion at http://www.dvgarage.com/prod/prod.php?prod=dvmatteb and it's only $99. They've got one for FCP also that gives you a little more to play with and costs $100 more. Download the demos for both and see what you think.
