Ultra Key (Chroma Key) Subtraction of Matte

Is there any way to "subtract" an area so it does not recieve the Ultra Key matte?
Example, I have a sequence which has a static object (a news desk) that has a slight reflection from the green screen spilling onto it. This object doesn't move within the shot and should never have the chroma key applied to it so I basically want to "remove the matte" from over the object. What I am asking for is the oposite of a Garbage Matte.
Thanks in advance,
Dave

I was hoping for something similar to the Garbage Matte but in reverse which would be very simple to use. I just played a bit with the Invert Alpha, but it seems to remove my matte everwhere else. Are they layer based, ie matter which level things are applied to? Will continue playing. Do you know of any tutorials that point this out?

How to invert the ultra key effect in adobe premiere?

Hi,
I'm trying to do a green screen shoot, except instead of replacing the background, I'd like to replace the person in the shot. I'd like to do this without greening the person. I have tried using the Ultra key effect and applying the invert effect on the alpha channel. But that gives a lot of noise, I want the "green screen part" to be totally black and the person replaced with another video or image. Is there an easy way to do this?
Thanks

So you had the ultra keys output set to alphachannel, the dublicated clip in track bellow with same ultra key plus track-matte-key with the track above as input, compositiong with set to luma matte and inverted. (or directly apply the track matte to the footage which should appear in the silouette)
If your settings is like this, what do the ultra key adjustments look like? with light and shaddow set to 0 and tolerance and last value set to 100 i get very low noise and a clear outline.

Ultra Key mask?

Does Ultra Key have Mask / Matte Only mode?
(I am a long way from my system and cant check for myself for a few days)
Would appreciate if someone could take a quick look and let me know. Be appreciated.
I am planning an edit and the approach to it for something I shot before I left on vacation.

I'm pretty sure you are thinking of Keylight.
I have often got away with holding back in Pr by duplicating the layer and adding a garbage matte to it - it works for green eyes/ ties etc.

Media Encoder Flips a ghost Ultra Key frame

First time using Ultra Key - Learning trial by fire.
I've created a short video using a Canon HF G10 and ultra key to layer the video for effect I want.
The Ultra Key is used for about 30 seconds of the 3 minute video and this anomoly only shows up during the ultra key treatment,
The original footage is AVCHD footage and I've thrown a lot of video effect filters at the footage with the Ultra Key.
The project rendered fine first go except I had to adjust the ultra key to prevent background from showing through one preformers black shirt.
After doing this I notice some flickering. What I found is an outline ghost image from the utra key track is flipped upside down and randomly inserted into the final render, also a rectangular monotone transparent block is randomly inserted at times.
Am I throwing too much at my computer or CS5?
I have more than 30 keyframes spread over 4 effects on that track, is that too many or too taxing?
I have rendered this clip a number of times and it seems when I re-open the project the Ultra Key footage isn't rendered so I render it again even though I am just making changes in the encoder. Let me know if you want to see those settings
I am using H.264 at 1080P drop frame and 60 Frames (so far)
This is for playback on a high def television from a computer.

I'm afraid you're taking it as an article of faith that Ultra Key works fine under all conditions.
A lot of work goes into getting a successful chroma key shot, good chroma key lighting being the absolute most important one. Adequate distance from the chroma key background to reduce spill is a close second. Without a screen capture of the original green screen shot, it's tough to diagnose what you did. But if you just put people in front of a green screen, shot and hoped for the best, I think you're running into green spill problems that won't be solved by a one-step keyer.
You may have to take the shot into After Effects, cut the shot up into various pieces using animated masks to get the keys straight, or you may even have to do some rotoscoping.

Can you do multiple ultra keys

If greenscreen has 3 or 4 shades of green can you open a 2nd ultra key in cs5.5 to get the darker dhade of green that was missed the first time around?? and another and another

You should - if you didnt' already - consider also using garbage mattes to cut unnecessary material out of your shots. If there are areas of the screen that never come in contact with the foreground/subject, then you can eliminate some of the compositing work by masking those out with the garbage matte. You can also animate the points on the garbage matte as well so that is an additional layer of control when you're trying to reduce the number of color variances on the background/chroma layer.

Adobe Media Encoder cuts off video layer when the Ultra Key effect is applied

I am working on a Mac (10.8.5) using the latest verison of Premiere Pro CC. I am using Ultra Key to remove the chroma key background from the "talent layer" and adding a "new background layer" behind the talent video layer. When I export directly from Premiere, the sequence exports as expected. However, I have many sequences, and wish to speed up the process using Adobe Media Encoder. When I export the same sequence using Adobe Media Encoder, the top half of the "talent layer" is completly cut off:
The issue has something to do with the Ultra key effect because when I remove the effect from the "talent layer" it exports in tact (with a chroma key background of course). Adobe Media Encoder CC is up to date as well; are there any known bugs with Media Encoder CC and the Ultra Key effect in Premiere Pro?
Thanks!

Complete Newbie trying to use Ultra Key

Hello,
I am a total newbie, and am working on learning to use my new green screen & lights :-) So far, I am able to get the vast majority of the green out.
Here is a shot of the green background:
Here is my background:
Here is my end result:
You'll notice the fuzzy remanants of the green screen after using Ultra Key filter.
How do I get rid of this? Any help is much appreciated
Thanks,

You do need to start of with a relatvely uncreased, evenly lit backdrop. I can see why you're having problems.
With just one eyedrop sample...
I would try and create a garbage matte to mask out as much unwanted background as possible and then try the key on the remaining content.

Ultra key Help

I have a greenscreen background that has too many shades to take out by ultra key
I drug another ultra key into video took sample of remaiining green thinking I could also adjust those remaining greens but it didn't really do anything
tried it with another ultra key now have 3 sampled image greens once again hoping to remove them nothing happened--what am I doing wrong??

Here is a nifty technique using auto-trace and a negative choke that might be helpful with an unevenly lit background.

Ultra Key - Blank out keying in an area

I am using Premiere Pro (CS6) and Ultra Key. Everything looks good except the subject is wearing a shirt with a logo and some of the logo stitching almost exactly matches my green screen (so the background is peaking through). Is there a way to cancel the Ultra Key in a small area? Or to mask or matte out the Ultra Key? Subject is not moving and camera is on a tripod.
Thanks.
Ps. I'm pretty new at Premeire Pro.

Thanks UlfLaursen for trying to help! UlfLaursen
Wow, I don't know how to phrase my question!
So here it is in pictures:
Green screen shot:
Not too bad for my first green screen! It's not perfect but pretty good.
(Wow, the quality is really reduced when uploading to the forum)
Here is the finished product:
But there is bleed-through in the green parts of the logo:
Is there any way to keep Ultra Key from keying that area (around the logo)? Can I mask it out somehow (would be kind of a reverse mask I guess)?
Any thoughts would be helpful.

Intermittent flickering on the ultra-Key Effect in CC 2014

Hello,
I opened an Project from Adobe Premiere CC 7 in Premiere CC 2014.
In this project I use the ultra-key effect. Now in Version 2014 I can't export a movie without intermittent flickering of the ultra-key track.
I urge you to help, because I have created in this converted project already a new movie and this can only export to said error.
Is there perhaps alternatively a way my CC2014-Project again in a CC 7.2 Project to convert?
Thnx
StoST

Here Some Details:
- Adobe Premiere CC 2014.0 (Build 8.0.0 (169)
- Apple OS X 10.9.3
- Source MTS-File 1920x1080 25fps
- Output: H.264 1920x1080 25fps (same bad result in all tested other formats)
- Worked before with the same Project in CC 7.2
- using Mercury Playback Engine GPU Accelerated
- The Preview in the working area is ok, without any flickering

How do you use the color channel output mode in Ultra Key in Premiere Pro CS6?

I'm wondering how the color channel output mode is supposed to be used in the Ultra Key inside of Premiere Pro CS6? I've looked through all the Adobe help items and I don't see any documentation on it.

Before I answer, you might want to read the following article: http://www.photoshopessentials.com/essentials/rgb/
So, basically, if you understood all of that, and maybe already knew all of that, then you can use the color channel to see more deeply into the effect by looking at the details of the image through the lens of the color channel.

Premiere Pro 5.5 crashes when I use Ultra Key

I saw this posted from last year. I just started having the same problem. I updated to 5.5.2 and the program started crashing every time I hit the eye-dropper with Ultra Key.
It was running fine for the last month through some pretty intensive green screen work.
Any ideas?
I also installed Silverlight and an mpeg converter but have already trashed both.
Thanks!

OMG!I such abuse!
Just kidding... I have three video cams one of which has a noisy mic, so the wave form is not as distinct as to make it easy as a good mic would..
The Markers just make the chore so much easier when they WORK! I can always come back and just realign them if I should bump them the wrong way or if I take a shot out and want to put it back in at a later date.

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!!
Thanks, Dru

Today 2014.2 was released. Might want ot update.

It is certainly not compatable with Mountain Lion so I would doubt if it is supported under ion also. Best way is to download it from here (only 13.5MB)
http://www.kilbot.com.au/2011/10/18/download-e-record/
and if it has a cirle with a line through it, as it does for ML then you will know it is not supported.
You can always contact Kilbot here
