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.

Chroma key effect in as3.0

Hi ,
How to make chroma key effect in as3.0. I am building an application in that while recording a video user can remove the solid background and inserts some other image it is done by chroma keying..
Any ideas please
Thanks

what i mean exactly is user starts recording the video in solid background environment so he can eliminate the background with chroma key and replaces with some image. The chrom key will hide the background show the user and in background he can place some image
this is chroma key effect

Could I have changed a setting that is not allowing chroma key to work

Very frustrated....I know how to chroma key (the process) but the eye dropper color selector is not working at all Doing something wrong, or locked something but NO idea what would be stopping this...this is a tough one....
Thanks

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.

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:

FCP Chroma Key requires re-render after any changes

FCP: version 602A89
In an HD 1080i60 sequence - there is a clip - the Chroma Key video filter has been applied to a pretty-well-lit 'stinger-green' backdrop. By making adjustments anywhere in the Chroma Key filter visual dialog, the entire green-field returns and cannot be eliminated except by re-rendering the clip.
See EXAMPLE IMAGES at http://www.glorioski.com/fcp/chromakey.html
I guess this could be submitted as a bug - but I am thinking there MUST be something I am not doing or have inadvertently set (or unset).
Any ideas?
Thanks! Lance Drake

Hi Jerry,
Hey thanks for your response to this question - but, I do not believe that this has always been the behavior with regards what has been presented in the canvas - at least for the current frame.
It's quite reasonable that re-rendering will be needed to apply the changes to the entire clip. However, my point is that, as adjustments in the Chroma Key filter are made - the results of the previous setting of the filter are completely abandoned and the single frame displayed in the canvas reverts to the case as if the filter had never been applied.
The BIG drawback to this behavior is that you cannot see how slight changes in filter settings affect what will be the result were you to go to the trouble of re-rendering the entire clip. Having to re-render with every adjustment sticks you in a huge time-hole.
I wish I had a system with FCP 5 on it - it would be interesting to see how FCP used to behave. Am I nutzo? Somehow I don't think so. It's my recollection that it was possible to make changes to the ChromaKey filter - see the effect of those changes rendered into the single frame of the canvas - and then it was up to you to cause the rest of the clip to be re-rendered.
Unless somebody kicks in with specifics regarding the error of my ways, I am thinking this should be submitted to bugreporter.

Chroma Key object creates only an apha channel when a second object is blended

Hi there,
I try to use the chrome key effect to have a person speaking in front of a background.
So I have 2 objects.
Video 1 = background (jpg-image)
Video 2 = video object edited with chrome key effect.
Layering both levels I see the background with the alpha channel of the second layer on top.
If I decative the first level (Video 1 = jpg image) I can see the videoclip with the transparent backgound.
What am I doing wrong?
Can anybody help me with that issue?
Looking forward for ideas...
Thanks from Germany!
Tom

Ultra key is the best choice for chroma keying.
Video with ultra key set on higher layer. In Your Effects Control Tab , the Opacity Settings value should at 100 with the blend mode set to normal.
Ultra Key (UK) set up should be listed beneath the Opacity & Time Remapping settings. Use the color picker in UK to select the green in your source clip.
Then fine tune settings. I like setting UK's output the Alpha when I am adjusting the quality of Key, then back to composite for preview and normal viewing.
You can prep the footage for keying with fast color corrector, boosting the chroma saturation and heightening the contrast(watch out for over bright whites) a little bit.
Still image on lower layer with no keying added and opacity blending on normal.

Chroma key effect

Hi All,
I am trying without success to use the Chroma Key effect only in part of the frame.
Is it possible? Can I draw the borders?
Thanks
Shaul

Coming from a stills background, I once years ago saw a video of a post-processing person in naturally film working (there wasn't this digital thing then) and he showed how they used masks, flags, & mattes in front of the camera during shooting of special effects. It was very elaborate work, some of it literally done by shooting a scene with a mask (totally blocked all but one part of the image from being exposed, cut to shape and placed just so in front of the camera), then re-winding the film and shooting with a flag over part of it ... then re-winding and shooting another section with both masks to block areas and mattes that were colored or painted for either shifting color/tonality or detail level or simply adding background/foreground to the image. Some of his work the same footage went through the camera 5 or 6 times, complicated re-registration on re-winds and exposure controls & all ... but allowed him to do things that couldn't be done otherwise.
What struck me at the time was he credited his ideas tools & techniques to Ansel Adams, the way he'd mastered making prints with held-back/extended exposures using precise shapes and movements to mutliple dodging and burning tools. This guy just did it on base footage in-cam, which sorta blew my mind away at the time.
Btw ... I was pretty frickin' hot with those tools myself, b/w and especially color prints. LONG time ago ... and your "cuts out the garbabe" comment is as good as leads to no never-mind (whatever the heck that phrase really transliterates as ... )

Good chroma keying app for ipod 4g?

Does anyone know of a good app for chroma keying (or green screening) on the ipod touch 4g? I have seen like ten or so, but was wondering if anyone here has used one that they really like?
Also if anyone knows of a good video editing app for ios? I was really dissappointed in imovie, i knew it wouldn't be like the mac version, but no editing of backround music, no choseing your own transition just using them transition for the whole video, and same w/ text!

Any ideas?

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!

PPro v2 chroma keys - help?

I'm working on a movie clip, I'm following lesson 13-4 from the PPro classroom in a book, and I want to use the chroma key to key out the sky in the sequence and superimpose an alien sky onto this clip. I've got a still image of an alien sky.
Here's what I did so far: I moved the video clip from Video 1 up to video 3 and the still image to video 1. Currently I'm trying the drag the Chroma Key from the Effects panel onto one of the video tracks as indicated in the lesson, but I keep getting a symbol that is a circle with a slash through it as I try to drag the chroma key onto one of the video tracks.
I'm a bit confused as to where exactly do I place this chroma key in order to key out the sky at this point - in the video 1, video 2 or video 3 tracks and do I place it before the clip starts or after the clip ends?
How can I drag the chroma key onto the appropriate track without getting this "no" symbol?
Also, I'm a bit confused by the instructions from this lesson - first it says to drag the the photos onto the video 1 and the video 2 tracks (but currently I'm working with only 1 photo at this point) and then it says to place the photos after the clip you worked on earlier - what exactly does this mean?
Thanks in advance.

hiya.
sounds like fun, doing the 3d stuff etc..lots to learn.
I only have cs3 so dont know about version 2 and what you can or can't do. A lot of people here will probably remember that version though, and help you more.
Also, I have maya and only use that ( and don't use it that much at all because like you I am learning how to use it and it is complicated for my snail - like brain ).
However, in terms of general work flows maybe I can mention a few things that will help.. and just remember I'm talking about maya and cs3.
I also have windows xp and mousey computer, so I can really only work with SD movies. HD makes my computer gasp for breath.
So I set up my projects in maya with the idea that in the end I will export it for SD to go into cs3 with that...
Consequently I have several options on the exports from maya...
a) numbered still images
b) avi movie
etc.
I have found that the numbered still images are nice to work with in cs3.
So I set up the project in cs3 for export to SD, which means even though I'm using numbered stills from maya ( with alpha channel ) I set up my project as SD NTSC 720x480 and choose par to suit my 4:3 or 16:9 aspect ratio ( usually I use 16:9 with par of 1.2 ).
Then I also choose a video renderer in new project that matches what I'm going to export more or less ( usually lagarith avi ).
In CS3 the alpha channel comes in with the numbered stills and that is where I drop in whatever background images or stuff I want to add ( like what you were saying about using chroma key to make a new sky ... the alpha channel is transparent, so you just add that sky without chroma key necessary ).
wav files are nice to work with in CS3 and I've never had any problems with them.
hope some of this helps and good luck and have fun !

Chroma key through Color

Any suggestions on basic workflow for sending a chroma keyed composite through Color.
I'd want to set the key prior to color correction and then color correct the foreground (keyed) image separate from the background.
My only guess at this point is to: 1. Set the key in Final Cut, including Color Smoothing if necessary 2. Do a preliminary color correction to both foreground and background using the 3-way CC 3. Send these to Color where the Primary room is set based on the 3-way from FCP
Is there a way to see the composite in Color (using alpha?) and color correct layers individually?
I'm probably missing something pretty simple...

Is there a way to see the composite in Color (using alpha?) and color correct layers individually?
Respectively: No. and Yes.
No, there is no way to see the composite in Color -- it is not compositing software,
and Yes, you do grade the layers individually. You might be able to get a very rough idea of the fg/bg plate balance using the still store.

Color correction and "sudo-chroma keying"-can they be done?

So I just wrapped my cousin's wedding, but the ceremony and reception were both held in a bar, which made for less than optimal conditions. Besides the prolific dim lighting, there were neon signs, specifically Miller and Bud Light. Those signs were both blue, so if I put on my outdoor color corrector, the video looked nice, but then if I panned, the regular ambient lighting looked off. If I applied my indoor color corrector for the ambient lighting, it looked good, but as I got close to the neons, it again looked bad. My question is, can I keyframe the 3-Way Color Corrector so that when I'm by the neons, it's as good or the same coloring as when I'm looking everywhere else?
My second issue came during the vows. Being a bar, there was a Budweiser sign on the wall, and it was paper and had just gone up, so it couldn't come down. I knew I was gonna be framing that perfectly, and unfortunately I was. However, the sign has a nice white boarder to it, so my initial and current thought is to chroma key it out and replace it with something like "Congratulations." I wasn't using a tripod, so the image moves slightly and there's 2 people in front of it, the bride and the groom respectively. Would it be easy to chroma out the white boarder which then would give me some space to matte the rest out. But what about around the people? How good of a matte could I do there? I'm thinking of something like the Magic Wand tool from Photoshop, but FCP doesn't have that. The sequence is only ~5 minutes, so not that long, but what would make it easier on me?
I don't have FCS2 yet, but if all goes according to plan, I'll be wiping my system on monday, installing Leopard, and going to FCS2 which means I could smoothecam that clip, so then my matting would be easier. In theory, I also will have Color at my disposal, but from the time I played with it at an Apple Store, it's too much for me, at least at this stage of the game. This wedding was done on the cheap, hence why I'm doing the video for them, so if I need to leave the color as-is, and the Budweiser sign in, so be it, but I'd really like to make this the best that I can, and neither of these experiments have I had much of any really experience with, so the more the merrier.
As always, any thoughts or help is much appreciated,
-Brian

+>can I keyframe the 3-Way Color Corrector so that when I'm by the neons, it's as good or the same coloring as when I'm looking everywhere else?+
good news, yes you can keyframe all the color corrector filters and it should work handily for your situation
+>I'm thinking of something like the Magic Wand tool from Photoshop, but FCP doesn't have that.+
try these, might be just what you need: http://www.lyric.com/fcp-plugins/lyric-effects/index.html
+>The sequence is only ~5 minutes, so not that long, but what would make it easier on me?+
your Brother got married in a bar under a Budweiser sign Brian, I'm guessing he won't mind having his wedding video reflect the reality of the surroundings, so why fake it? ... easiest on you would be to leave it as it is 'cos theres nothing worse than a dodgy effect.
hope that helps

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

Can you do Green Screen/Blue Screen/Chroma Key on Adobe Premiere Elements 12 for mac?

Can you do Green Screen/Blue Screen/Chroma Key on Adobe Premiere Elements 12 for mac? If not, what are the alternatives?

JimbobT
ChromaKey, GreenScreen Key, and BlueScreen Key are not included in Premiere Elements Mac.
Some suggest Videomerge as the alternative. I do not. But Videomerge is not THE alternative.
Instead, I prefer the Difference Matte as a substitute for the 3 absent keying effects. Please check out my blog post on that which includes
the how to.
http://atr935.blogspot.com/2013/05/pe11-difference-matte-as-substitute-for.html
The suggestion has met with good results according to the feedback that I have gotten to this.
I am strictly a Premiere Elements Windows user who does not prefer Videomerge even in Windows.
Please review, consider, and let us know the outcome.
Thanks.
ATR
