Chroma Key with live footage.

I was wondering if any one knows how to use a camera to do chroma keying with a live feed. We want to make it look like the person is stand some where else live. Simalar to do the weather.

You need an external keyer. On the cheap side, there are things like the Videonics MX-4 SEG switcher, and, of course, the sky's the limit on the other side.

Plug-in or 3rd party for Chroma keying with DV footage

We shoot Betacam SP, captured to DV with a DSR-45P DV/DVCAM deck.
From what I learn on the web, green is preferred if you edit on DV, due to the color sampling. (4:1:1 for PAL?).
However, it also depends on what background you have. Use green if you are in the forest, use blue if you are at the beach. Sort of.
The built-in chroma keying in FCP is OK, but not more than that. What do you recommend using?
I've found the dVMatte from www.dvgarage.com - is it good?

Just for DV media, the AdvantEdge plug-in from Ultimatte has a preset. It has a resampling method for 4:1:1 (or 4:2:0 if PAL) media like DV.
Take a look:

Can I use Chroma key with première elements 13 to incrust a picture in another one ?

en français
Bonsoir à tous
Avec première éléments 13, peut on incruster une image dans une autre en utilisant par exemple un fond noir et en supprimant ce fond avec le chroma key ? Je n'ai vu cette possibilité que dans première pro
Dans la version essai, y a t-il un logo Adobe sur les films montés (en filigrane ou autre) ?
Merci d'avance de vos réponses

Regarding your second question....you cannot remove the Adobe watermark from an export from the tryout project file, be the export a file saved to the computer hard drive or a burn to disc product. You can remove the Adobe watermark from a project file from the tryout if you open it in the purchased version.
Two ways:
a. open the tryout project file in the purchased version, use Timeline Menu/Delete Rendered Files and the Adobe watermark should be gone.
or
b. open the tryout project file in the purchased version, and do nothing...the Adobe watermark may disappear automatically.
The way "a" is the classical way. But many of us have found "b" to work for us.
What is the computer operating system involved? Premiere Elements Mac does not have ChromaKey, Green Screen Key, or Blue Screen Key.
It has Videomerge which I do not prefer. Instead for Premiere Elements Mac users, I would suggest the Difference Matte.

If you are using Premiere Elements 13 Windows, please refer to fx Effects/Keying/.
Any questions or need clarification on any of the above, please do not hesitate to ask.

Chroma key with LiteRing - any one used this system...

Is it any good. Pitfalls, stregths, ease of use...
See: http://www.reflecmedia.com/content.aspx?Content=litering.htm
Thanks for your time.

I kinda like this system (even with dv). It is not a too good to be true system. One big problem With it is you have to have your camera at a good distance because it does cause problems with the spill. You also get a horrible ring reflection in your subjects eyes. but for the portability, the ease of setup, and I think it actually keys pretty good, I like it and actually use it regularly.

Chroma Key FCP 6- Footage is perfectly Keyed, until I hit render, and then only v2 plays

Before rendering
AFTER RENDERING

Is the curtain clip ProRes as well?
Have your tried trashing your FCP Preferences?
It is the usual first step when FCP begins to act unexpectedly:

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.

Chroma Key Software for Mac

I'm interested in doing chroma key for live broadcasts. I have a video mixer and the green screen. I know I need a computer as well, so I was wondering what software anyone can recommend that will work well with my new mac.

That would depend upon your OS. Your profile is blank

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.

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.

Intermittent problem with cross dissolve and chroma key

It seems that in 1 out of 10 videos I produce in Final Cut Pro there is a problem with the cross dissolve effect and chroma key. What happens is that during the cross dissolve, clip A fades out with a green tint and clip B fades in with a green tint.
Today I am working with two videos that I captured using the same work flow on the same day. One project exhibits the tint while the second project does not. If I import the problematic footage into the good project the tint problem follows the footage. In the good footage, the cross dissolve produces a result that does not have a green tint. If I re-capture the "bad" footage the results are the same.
Has anyone else experienced this and does anyone have an idea how to resolve this problem?
Thank you.
Dual G5 Mac OS X (10.4.6)

In my project, both clips are source clips with Chroma, Color Smoothing and Matte Choker applied. A dissolve from non-chroma clip to chroma clip works fine. Only problem is with two chroma clips. In my dissolve, the error appears as red fringing in the area between the two masks.< </div>
You're using creative shorthand that doesn't help. "Chroma clip" means the clip to which you have applied all of these effects? What masks? Where are you getting the masks?
To understand what's going on with all them itty bitty pixels in a stack of interactive effects, do me a favor: render out a short piece, say 10 seconds of each of your chromaclips as separate movies over transparency using the Animation codec. Reimport them and put them over a solid colored Dissolve between them using different types of dissolves. Post back and tell us (me) what's going on.
I still consider this to be a bug -- nesting adds more steps to the workflow than if this bug did not exist. < </div>
It's not a bug. Your pixels are running down a pathway. It's a question of building the correct pathway and having the correct pixel wranglers with the right kinds of cattle prods.

Vertical lines showing up after rendering chroma key on Canon 60D footage...

Ok so I am working with Final Cut Pro 7 right now and this is my first green screen attempt.
1) I shot the footage with my Canon 60D and did a log and transfer so I could make the H.264 files into Apple Pro Res 422, the correct method.
2) I then applied Color Smoother 4:2:2 , then Blue and Green Screen and selected green, then Spill Supressor, then Matte Choker, then Mask Feather. After tweaking the parameters throughout the filters I came out with a perfect image.
3) I then tried placing another ProRes video underneathe of the clip so that the video would show in place of the green. It worked and looked great.
HOWEVER
4) Upon rendering and playing back through the final image I noticed vertical lines running down the 60D footage. At first I thought it was the image underneath coming through, but even after removing the image and simply using chroma key until the green turned to black and rendering again, the lines were still present. Am I doing something wrong?
Please help, I have a deadline
-Eric Widder

The HQ flavor of ProRes is overkill for this footage (I also have this model Canon), but that's not really important to fixing your problem.
Further to what Rv told you: I've long been advised by people who are savvy about keyers to avoid the stock FCP keyer and use the Primatte plug-in – and that's been my go-to tool. Recently, I tried the new keyer in Motion5 and was very impressed. I tested it on a project I'd been only OK about and found it made a huge difference. If you're going to do a lot of this kind of work, check it out. For $50 the keyer alone is worth it.

IMovie 11 with chroma-key and watermarks

I'm new to iMovie. I did attempt to find the answers to the questions below here and on the web. Frankly iMovie so far seems to be pain....
setup for my testing purposes only:
a) borrowed chroma-key movie from the web
b) borrowed m4p from the web
I wanted to test my ability to use chrome-key and watermarks in making a short clip using 3 products...Screenflow 4, iMovie, Final Cut Pro X.
Questions and/or statements:
1) Green-screen:
Screenflow and Final Cut took about 5-10 minutes with zero knowledge of either...Over an hour with with iMovie and never could make it work.
2) Watermark:
Aganin 5-10 minutes with Screenflow and Final Cut, with iMove it looks like I could have either keying or watermark, but not both.
Screenflow is SUPER simple and cheep (on sale today for $70), I've seem it 50% off...
Final Cut is OUTSTANDING but super costly for what I wanted to do....Really a great product.
Anyway, here I am with a iMovie and so far it looks like it isn't a fit for me...Anyone know if a way to tweek it to make both chroma-key and watermarking work? I guessing it's just me, but the others seemed so simple.
Attached are screen copies of each...in order below are iMovie, Final Cut Pro X, and the output of Screenflow....
I want to thank those that I borrowed these images from...I will not use them beyond my testing....
Thanks for any helpfull hints...

iMovie is designed with a very forgiving green screen feature so you can hang a green bedsheet on a wall and get a decent effect. It is designed for people making home movies. Perhaps for this reason, if you have a perfect green key in iMovie, then iMovie might think you used the green on purpose. It expects some variation. When people are doing computer generated graphics, or creating a green background with Photoshop or Keynote or Powerpoint, I suggest using a gradient between close shades of green, rather than a monochromatic green.
If you need sophisticated control of your keying, get FCPX. I am not familiar with Screenflow.
Also, iMovie does all rendering in one pass. This means it cannot do effects that require a render on top of a render. Say you want a greenscreen effect with a watermark on top. That is two renders. This is easy in Final Cut Pro, but not possible in iMovie without jumping through some hoops.
Also for this reason, longer movies should be done in FCPX. What for iMovie would be an immense job requiring huge resources, FCPX can do by chopping it up into bitesize pieces.

Chroma Key problems with Final Cut Express 4

I had no problems with the Chroma Key in Final Cut Express 4 before. It was working perfectly fine untill I brought anther Macbook Pro last year in August. I installed it on the new computer and then the Chroma Key didn't work. Final Cut opens up and the other filters work fine but I can't get the chroma key to work. Any possible reasons?

I am experiencing an interseting problem with Final Cut Express on OSX Lion. I teach in a Mac Lab at my school. Today I was trying to teach Chroma Keying- which I have been doing for years - but for some reason the color selector would just not key out anything. I tried it on four or five different machines, and it turns out that ONLY my machines that were running OSX Leopard would allow the Chroma Key to function. I have two machines running Lion and the Chroma Key would not work on EITHER of them. I followed the exact same steps, and all of the settings were identical. The hardware was also the exact same package from machine to machine. I feel like there must be an issue with OSX Lion that is breaking the Chroma Key filter. Can anyone help?

Live chroma key in FCP??

Need a solution for live chroma key in FCP to be output to the web. I am really new to FCP and wonder if there is a way to do live chroma key. I have a bunch of cameras D-9, DV, Beta, and a green screen stage and a DSL web link. Also, have a Kona AJA LHe card. If anybody has the time would appreciate some input.
Thanks
John

Saw a demo of this at MacWorld from PixelCorps. Not sure they used FCP, but it was indeed all live and very good. Had an HV20 hooked up via HDMI to a decklink card and was cranking in some un-godly number like 190 mbits of dataflow. Beautiful keys.

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.
