Strange brief green tint changes in MPEG-4 bitstreams

I'm running into a strange issue that seems specific to QuickTime. When I try to play certain MP4 files containing MPEG-4 Advanced Simple Profile bitstreams, they play back generally okay, except that, when there's motion, everything will suddenly have a greenish tint, and then change back to normal colors. The bitstream seems to play okay with VLC, Elecard, Windows Media Player, and DivX, so it seems specific to QuickTime.
Interestingly, if MPEG-4 Simple Profile is used instead, everything is fine. This makes me wonder if this is an issue with how B-frames are processed.
Has anyone seen anything like this before?
Thanks for whatever help you might be able to provide.

Thank you for your response!
We tried both the "Safe mode (GDI only)" and
"DirectDraw" in the "Advanced" tab under
"Edit - Preferences - QuickTime Preferences."
The intermittent green tint when there is motion
still appears in both cases. You mention a video card
issue. Do you know which card(s) showed this problem in
the past?

  • LR 2.3 applies a green tint to RAW image AFTER making adjustments

    Hi all,
    Thanks for having this great forum, it looks like there is some great information here. I clicked around the LR threads and the FAQ but I haven't found anything applying particularly to my issue/question, though, and I'm hoping some of you can help me understand what is going on. .
    I have read about LR changing the colorcast on import, however in my case the images look fine after importing and processing. When I click BACK to an image that I have already processed, I am seeing LR 2.3 apply a green tint to it, and I have no idea why.
    What I am doing:
    -Import Canon RAW files into LR collection (images look fine, no abnormal colorcast)
    Develop tab:
    -I can click around the collection and view the images without any colors changing
    -Process an image to my heart's content (image color still looks fine)
    -Click to the next image and process the next one
    -Mouse-over on the previously processed image on the bottom filmstrip, and preview shows up on the Navigator pane (preview looks as the image was edited previously)
    -if I click to a previously processed image in the filmstrip, it will load into the center pane
         -while the processed image loads here, the green tint gets applied to the image
    -Color tint/green saturation has not moved from its previous position (even if it was moved during initial processing)
    -In order to correct it, I either have to adjust the color tint slider about 20 points away from green, or dial down the green saturation to compensate.
    Once I re-correct the image, I can click back to it again, and the mysterious green tint will no longer re-apply itself on this image.
    This happens to most if not all of the images in the collection. I have only processed one other RAW collection in LR, but I did not have this issue.
    I dont know what exactly is being changed to result in this green tint applying on its own, so I'm not sure if the adjustments I'm making are correcting it.fully.
    I hope I'm detailed enough in explaining what I'm seeing, and that it makes some kind of sense.
    Does anyone know what is going on here?
    Thank you!

    Hi John, thanks for the reply.
    Thanks, I'll look into the preferences in LR, although everything has remained mostly in its default settings. I've loaded JPG collections without seeing this either.
    Would monitor profiles matter in my case? I ask because I am simply clicking back to a previous picture in the strip. When I leave the picture it looks fine, and returning to it shows that image but with the green tint. I haven't gotten to the point of exporting/converting the image, or anything further.
    Some more information if it helps:
    Using MS Vista
    Using Canon Rebel XTi 400D
    I copy only the raw files from the memory card to a folder, and then point the LR Import to that folder.
    I will try replicating the issue on another computer in hopes to narrow it down. I am baffled.

  • Monitor went temporarily to black and white with green tint

    Last night when I turned on my computer my monitor showed only a black and white picture with an overall green tint. I restarted it, but the same. This morning, however, it is back to normal. The strange thing is that my house lights seemed to be dim, too. (I thought it was just me until I turned on my computer). Is this a sign that my monitor may be failing, or some kind of fluke?

    It is, but only with a lot of compositing.
    In FCP this would be doable with garbage mattes, but you'd need the 60 point one from Paul Crisp...and that wouldn't be fun.
    In After Effects, you'd have to mask everyone else, and again, keyframe.
    Shake might do this well, and it is on the cheap now. But it has a HUGE learning curve. And I have no doubt that even with Shake you are looking at a frame-by-frame manipulation.
    Good effects aren't easy to pull off.

  • Opened LR2 in Vista32 Business everything had a green tint

    Hi,
    Just for the record I like to say that LR2 is incredible!!! I have been using LR since 1.0 and what a wonderful journey it has been. I like to consider myself very experienced with this software, but I am recently puzzled about an issue that has only happened twice and was wondering if anyone has had the same issue.
    1) The first time: Opened LR2 in Vista32 Business everything had a green tint, every catalog, every image was just green. So I closed and rebooted my PC, reopened LR2 and everything was ok. So I figured weird but no big deal, never happened again until!!!!
    2) The second time: Same thing, but this time it will not go away. I even went as far as pulling a backup of one of my catalog files and the same thing.
    So anyone???
    Thanks in advance.

    There is a very subtle effect you might be able to see in the shadows where Lightroom will look slightly different from any other color managed program. I had a discussion with somebody else with an eye-one that had that problem that disappeared when using matrix profiles. You might never get to see it though. This is far subtler then your green problem though on your PC.
    Regarding the strong color tint, often what I think happens is that a windows machine gets some sort of driver update that the user just installs without thinking about it. This driver update however contains a hidden monitor profile. Often they are the new Microsoft version of v5 profiles done by a monitor manufacturer but never tested with Lightroom. Those tend to hose Lightroom's color display. A good indication of this is when the Histogram display looks off - i.e. the area that is supposed to be grey has a strange tint.

    I have a DeskJet 979Cse. ever since I got a new computer with Windows 7 (64 bit), every color print has a green tint.
    I've tried changing the color management profiles and calibrating the monitor, but I still get a green tint on every color print. The image looks fine with the correct colors on the monitor, but when I print it out I get an image with a distinctive green tint.
    Other than this disturbing color problem the printer works normally.

    Say Thank you Microsoft. MAPI, the tool used for most of the "mail magic" in windows is depreciated and not included in Windows 7, it can be made to work on 32 bit Windows 7, bit 64Bit such as I have just does not play. Microsoft Office, word particularly is hard coded for Microsoft Outlook, so sending mail from Word is quite difficult.
    My solution has been to Dump Microsoft and use the Free open source LibreOffice. I don't have to do battle with the ribbon either and that is a god send.

  • Palm Pre camera preview has green tint

    I have had my Pre for about 1 week and have taken many pictures with it (uploading to facebook, etc.).  As of today, when I launch the camera application, the "preview" I see on the display has a green tint to the picture.  If I press the camera or spacebar to take the picture, the resulting image looks fine.  It is just this preview of the picture that has this green tint.  All other aspects of the display look fine - running video, looking at pictures, etc.
    I have tried the basic reset and hardware tests but nothing has changed.  Any ideas? 
    Post relates to: Pre p100eww (Sprint)

    yeah i don't find any options in there either...
    i guess they are working on it....
    and some exposure and effects might also do on the next update.. and also ability to add date on the photo is another feature too..

  • Green tint apparent on photos through Rear Camera

    I was using my iPhone lastnight at work, downloading some apps, and doing the normal iPhone stuff. The phone was normal and fine, and I did use the camera earlier during the evening to take a photo of a document letter.
    I placed the phone on my desk, (back side down), so the screen was upward facing. There wasn't/isn't any bright lights or anything. The iPhone was laying on a piece of paper, so nothing out of the ordinary.
    A few hours later, I turned the iPhone on and went to take another photo of a document. I then realized a "green" tint in the center of my screen. At first I thought maybe it was what people call "Pixel Burn" but then realized after I left the Camera.app and went to any other part of the OS, there was no Green tint. I also tried the Front Facing Camera, and no green tint either.
    I then tried the Rear-Facing Camera again... and the Tint is still visible. I am at a lose for words as to what would even cause such a thing. I've attached a few photos so that you may see what I am talking about...
    Also.
    I've restarted. Uninstalled the last App I installed, which was Box.net, and nothing changed, it's still there.
    Any ideas?!
    I've had the phone for just about 2 weeks.

    I've swapped two phones for this issue. While I have seen it on some phones I have not seen it on more.
    The one I have now dosnt do the green thing like in the pics but two others did in the same room so I know it's not variation in occasions. It seems while all iPhones u might see a very light green spot under certain lights if you really realy try to find it. And a few u can just tell by looking at it

  • Monitor flickers with green tint

    Monitor is about 3 years old. Often times, the screen takes on a blue-green tint. Sometimes just flashes on, then back to normal a few times.  Sometimes tint stays for a minute or two. All images are visable, but everything has a strange greenish cast to it.

    Hello @snelson600,
    I have read your post on how your desktop's monitor flickers with a green tint, and I would be happy to help you!
    I am providing you with some steps you can try below:
    Step 1. Unplug the power cord from the back of the monitor and the wall
    Step 2. Hold the power button down for at least one minute
    Step 3. Plug the power cord back into the monitor and then into the wall outlet (not a power bar or surge protector)
    Step 4. Press the Menu button on the monitor
    Step 5. Navigate to the Factory Reset option and select it
    Step 6. Try a different cable connecting your monitor to your computer
    If the above steps did not resolve your issue you can try the monitor on a computer or other device to see if the issue persists. Please call our technical support at 800-474-6836. If you live outside the US/Canada Region, please click the link below to get the support number for your region.

  • Sickening green tint to certain icons

    There is a green tint to some of the new icons including the new hard drive icons, the Security and Privacy preference pane, etc. It makes me feel a bit sick - I realise that's more my problem than the changes themselves, but I do find it to be quite off-putting. I can change the hard drive icons, but the preferences are a bit more difficult to alter. My solution for the internal hard drive was to use the USB drive image and changing the colour from orange to blue. If anyone else is interested, here's my solution:

  • HT2513 my iCal calendar that I created with the color green keeps changing to purple.  no matter how many times I change it to green, it turns it back to purple.  Of course this only happens with iCloud and not "from my Mac".  Any ideas?

    my iCal calendar that I created with the color green keeps changing to purple.  no matter how many times I change it to green, it turns it back to purple.  Of course this only happens with iCloud and not "from my Mac".  Any ideas on how to correct this?  This seems like a trivial error, but it's super annoying.

    I called Apple and they said that they know about this problem.  It's a problem with iCloud which their Engineers know about.  (there was a new iCloud release, hence...)  No ETA for a fix yet.  I asked that this be escalated so Engineering doesn't put it at the bottom of their fix list.  I talked to a Senior Advisor and mentioned to them to have QA check their regression tests as this has happened before to me (the problem just didn't take this long to resolve).  I like to use green too for important stuff, so I've resorted to creating a new calendar using the normal calendar green for events going forward.  They could have picked another color besides green to have this problem with and I wouldn't have been so upset.  ;-)

  • Why do my photos have a green tint when placing them into Muse?

    I am placing photos of portraits into Muse and the colors look terrible. There is a green tint that dulls down the pictures.Top is one of the originals, and bottom is a screenshot in Muse.

    sorry maybe Im not making my issue clear...thanks for answering anyway:
    over the last years- but 15 weeks specifically I have downloaded photos from my camers card- putting it straight into the apple mac and then opening IPHOTO then i am able to click and put the pics into my folders in IPHOTO but as of 2 days ago - the camera card went in, the pics opened BUT there is an error message which states iphoto cannot save them to file......as they are JPEGS
    I can see that others too have had this issue and there are 'answers' but I am a complete novice and cannot understand the answers given and need someone to 'hand hold me' through a step by step this is what you must do....
    so hope that now is cleared as to why there is a 'problem'
    hope you can still help me thanks for you time

  • Green tint to Macbook Pro Retina screen.

    Hello,
    I have a Macbook Pro Retina less than 2 months old, earlier today the screen started to get a green tint on everything. I already attempted adjusting the color profile, which didn't affect the greenness of the screen.
    Thoughts?
    -Peter.

    Ok, the EXACT same thing happened to me, although I sneezed all over the screen (gross) and then wiped it off with a windex covered paper towel. Then followed up with a damp microfiber towel to remove smudges. There was no way that water could have gotten in nor the windex.
    So I raise you this question; did you use a microfiber cloth, and are you in a dry-cold or a dry-hot otherwise low humidity climate.
    The reason I ask, theoretically if you did use a microfiber, had the computer on, and rubbed back and forth across the screen several times, you may have created static electricity, which may have interfered with the screen.
    I found that after doing several power cycles (command+control+p+r+power) the green tint completely disappeared. I also noticed that the cat hair that flies around my house is not sticking to the screen anymore....
    Food for thought

  • Green tint when hooking G4 PowerBook up to LCD projection

    I've been hooking up my G4 to external projection for presentations for a long time and then all of a sudden last week whenever I hooked up to display information to a group the projected image had a green tint. The image always looks fine on my computer but the projected display is really ugly and hard to look at. Any ideas on what the problem is?
    G4 Mac OS X (10.4.5)

    Hi lwb2000;
    First issue: "Green tint" Possible cause - damaged DVI connector in Powerbook, monitor video cable not seated correctly, monitor video cable may be damaged, or monitor connector on video projector may be damaged. Inspect the connectors at all points in the chain.
    Second issue: "display is really ugly and hard to look at" Launch Display Preferences in System Preferences and calibrate (under the 'color' tab) the projector monitor settings.
    Hopefully this will help you.
    Take care.

  • When I am streaming videos there is a dark green tint to the darker colors on the screen.

    When I am streaming a video, there are dark green shades to some of the darker areas on the screen.  For instance if someone in the video has dark hair, there are green tints to the hair.  It almost looks like a color negative, but not quite.  This has just started happening.   I've had my mac book pro for about 2 months.

    Could you please give us a picture of what is going on. This is a picture of what the top of Safari looks like when I go to the Help menu. I typed in the word cache and a number of options appeared below. Is this not happening for you?

  • HT201173 how come my screen is green tinted?

    how come my screen is green tinted?

    Generally a green tinted screen is a result of a poor video connection to the monitor. Try unplugging and replugging each end of the video cable and while you are at it, examine the contacts for signs of corrosion or dust. The unplug/replug will usually clean any crud off of the connectors. If that fails try another video cable. Connections inside the cable at either connector can get broken or damaged. If that is the case replacing the cable is easier and probably cheaper than attempting to repair it. If you still have a green tint the video card in you Mac mini or its connection to the logic board could be at fault and in that case a trip to the Genius Desk at the nearest Apple store is warranted. (Be sure to go online or call ahead and make a Genius Desk reservation before you go. That can save hours of time waiting for them to "work you in" to an already jam packed day.
