Ultra Key flickering

Hey,
I'm working on a brand new Mac book pro with 16GB ram and have recently downloaded the new Premier Pro CC (7, I guess).
I'm creating videos with mulitple tracks layered over eachother, one of which is a green screen track which I ultra key out. At the moment, as soon as I apply the ultra Key that track starts to flicker on and off intermitently. Any suggestions of what I can do?
Thanks!

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

  • 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

  • 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.

  • 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!

  • 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.

  • 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.

  • 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

  • Bringing Premiere ultra keyed footage into after effects with key intact

    It there a way to bring in footage I keyed using Premiere ultra into After effects? I much prefer the ultra keyer over anything native to After Effects CS5.5. If not, how do I export and keep intact the aplha channels from the keyed footage into after effects? Thirdly, if I have to, how do I remiove the black background I get as a result of a default quick time movie file?

    You can not export a clip with alpha from PPRO.
    Easiest way is just doing the key in Keylight - AEFX ( which is far more powerful and flexible than Ultra Key . As good as it is, it has its limits)

  • CS5 Ultra Key is sweet...

    Been doing some tests and I have to say... Ultra Key is well worth the "price of admission"
    What a sweet addition to PPRO.
    I do a lot of keys and it was my workflow to do a quick and dirty in PPRO for the edit then go to AEFX to online it via an intermediate.
    The time saving for me now is significant and the bonus...REALTIME.
    CS5 and MPE have surpassed my expectations by a long way.  BRILLIANT WORK ADOBE.  (This is a serious game changer and I cant wait to show this off to my FCP colleagues and peers)
    (still a shame about Opacity Keyframes though...but then again ....at least they are realtime as well)

    From my limited experience with Rotobrush, it works really well. There's a lot of factors that go into getting a good roto, but from the few clips I've tried it on, it has worked really well. I fixed a shot for a project my wife was doing - interview with someone who was very underexposed. Used Rotobrush on the subject, adjusted the brightness on him, and laid it back into the color corrected shot...it took all of maybe 20 minutes (it was a short interview clip).
    As for Ultra...I can't say enough good things about it...it will make my life SOOOO much easier!
    CS5 - where have you been all my editing life?

  • 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.
