Pixelation issue continues......

Hi all. I just did a edit on a wedding and there was a lot of pixelation durring the edit and on the print to tape. I did use a tv for preview and pixelation was visible. Now just to fill in some additional details. I captured it usig my Canon XL2. The shoot was done by some one else using a Sony 3ccd camera of some type. The tape is a panasonic mini dv tape (AY-DVM63PQ). Is it possible I may be having a tape,player caturing stew that is the cause of the pixelation? If additional nfo is needed please let me kow. Thanks all.
Raymond

Well it looks like I may have resolved this issue, sort of. John (owner of the tapes) let me borrow his camera for the experiment (Thanks). This is what I did with the theory that if I captured using a sony dcr-vx2000 pixelation would be reduced.
The other night (late), I pulled some hurricane Katrina footage that I had not captured yet and capture it with the canon xl2. on playback of the capture NO PIXELATION was observed at all(I watched it three times). I took the originalvtapes that I worked with last week on the wedding and recaptured on the caon xl2. Resulted in occasional pixelation. I then took the same tape and re captured it from the sony camera. Resulted in NO pixelation when playback observed on a tv and on pc screen.
Conclusion:
even though ths is not scientifically provef true or fals, I observed that to capture from a mini dv tape if shot on sony camera, you need to use a sony camera for capture. Same thingapplies with canon.
Note: Canon and Sony, please address these issues as a professional courtesy to the rest of your customers. Thank you.

  • Video Pixelation Issue - New HP Pavilion 15-P008TX Notebook - Windows 8.1

    Ahoy,
    I've seen topics regarding this issue - i.e. first day running a new HP Pavilion 15-P008TX, using Windows 8.1...
    However the video quality on videos being played from the DVD Drive, HDD, and streamed videos (e.g YouTube) are extremely low quality.
    Unfortunately I can't screenshot the issue - the best way to describe it would be to say that the videos look like YouTube videos being viewed on 144p
    DVDs, and even 1080p videos are low quality and pixelated...
    So far I've tried the following to no avail:
    - Uninstalling and Reinstalling intergrated video drivers (Intel HD 4400) and Nvidia 3D drivers (Geforce 830M)
    - Switching scaled views in the display section
    - Installing VLC (with the latest codecs) to test if it was a codec issue
    - Running a windows update
    - Changing Graphic settings that may intefere with issues in quality (both Intel HD settings app and Nvidia 3D settings)
    Windows Apps and programs aren't affected, only video playback.
    First day of using my new HP Notebook, and i'm hoping to resolve this issue promptly.
    Cheers.

  • AS2 noScale and pixelation issue

    We are doing a number of banners for a client in AS2 using Flash 8 Pro. The version was their specification.
    Now I've generated a series of PNGs in photoshop at precisely the same dimensions an imported them directly into the Flash Library.The problem is, when we epublish this to HTML it scales up about 120% and pixelates badly. I've already explored a few workarounds to varying success. Allow me to explain:
    In the swf preview (Ctrl+Enter) I get no scale or pixelation issues. The render is clean and sized correctly. The scale problem is only happening in the HTML publishing.
    -I double checked the code on the HTML and the size specifications are the same as those in my FLA and PSD. Identical.
    -In the publishing settings I discovered that the noScale option prevented the issue, but only for the machine I was working on. None the other test machines saw any improvement in the published banner(we have 4).
    -I tried embedding a noScale Actionscript directly into the FLA. Same issues as above. Only the work PC displayed the correct size, the other machines did not.
    -I tried manually setting the HTML publish size specifications. Again, same problem.
    What's strange to me is that the noScale only corrects the problem for the machine the project was done on. Makes me think some caching is to blame for the misrepresentation. And the HTML Publish seems to be ignoring my size specifications for the SWF altogether. Can someone tell me why this is happening?

  • Error 100a --- if this issue continues, please contact HP Support

    Hi, got HP DV6-1103AX and did a clean form yesterday. The whole recorvery process had no option to create a new partition besides factory partition - one huge 221GB (system boot etc) and one Recovery Partition. Tried on windows disk management and it could only shrink 9GB that is bit pointless. Then I ran Partition Wizard freeware and apparetly it could shrink 9GB as well. This software requires HP notebook to reboot and one page shows 'no reboot device found'. In that case, I had to restart with F11 and do a clean recovery again. Half way, I was told 'Error 100a --- if this issue continues, please contact HP Support'.
    Please let me know what I should do to fix this and how to create the additonal partition (150GB or bigger)  besides the factory 2 partitions (C: system boot & D: Recovery)

    Thank you. Tried a partition software, can't remember 'Partitiion Magic' or ' Partition Wizard'. It did partition a new hard hard max size 9GB, same result as 'diskmgmt.msc' in Windows. Anyway, the worse problem is after the partition, HP fails to recover the system and gives Error1000a. When HP has such a message, what shall I do next?

  • Besides the pixel issue any other reason not to use iphone apps in ipad?

    besides the pixel issue any other reason not to use iphone apps on ipad??

    There are no technical reasons why you can't use them (unless they are some of the few apps that require full phone capability which you won't be able to install). -If you are happy with either using them in an iPhone sized portion of the screen, or with the pixelated 2x size, then use them. I use quite a few apps from my iPhone and iPod Touch, and I've got used to the pixelisation and I don't really notice it as much as I used to.

  • 9800 XT residual pixel issues

    Hi everyone, I have a Dual 1.8 G5 with 2 gb of RAM and a Viewsonic VX2025 LCD monitor. I recently purchased a system pull 9800 XT card from OWC a couple of days ago and popped it in.
    I know this card was an upgrade option for my 1.8 from Apple so I thought there should be no issues with it...not really.
    I have been suffering some odd pixel issues...not really pixels but rather sizeable SQUARES all over the screen. Hovering a window or even doing a selection area will remove these 'pixels' but will reappear later on. Not in the same spots mind you. Happens as well when watching DVDs.
    Games are the worst. It's almost as if I can see the refresh or 'scan'. I have zapped the PRAM, I have repaired permissions and have even popped the card in and out to make sure the contacts are true.
    Please please please...anyone with advice, any advice!
    Dual 1.8 G5   Mac OS X (10.4.8)   2gb RAM and a Viewsonic VX2025 monitor

    Ok, I'm back and the card is acting up again.
    A few days ago, I walked in my computer room and saw my G5 had the gray screen crash. Fan was kicking hard. I did the shutdown and restarted after 15 seconds. My screen was suffering the pixel/quilt issue I had awhile ago.
    I ended up raising the overclock of the card from 5% to almost 10% to make the pixels go away. Also, from boot up, It seems there is quite a delay for aticellerator to kick in and the initial screen is riddled with squares. I have to activate the screensaver to 'wash off' of pixels and get a decent desktop.
    I have tried reinstalling aticellerator.
    I have physically removed and reinstalled the card.
    I have downloaded whatever drivers ati had to offer for the 9800xt.
    I have even reinstalled my system. I did this thinking maybe with a fresh reinstall and Tiger having a chance to rescan my current setup would be able to install the appropriate drivers...in case there was a conflict somewhere.
    Any advice anyone? Thanks!

  • "Slow typing in Mail" issue continues in Lion

    The "Slow typing in Mail" issue continues in Lion. Has anyone found a fix yet?

    Well, when typing in MAIL, the letters manifest VERY SLOWLY. I am know ACE typist, and it can't keep up with me. I type even a few characters, and wait for several seconds for my textual desires to appear.
    This was well discussed under Snow Leopard, I see.
    Restarting the App often helps for several minutes, but no more.

  • Graphics corruption issue continues in Mavericks 10.9.1

    Bad news: A graphics issue reported for Mavericks 10.9 continues in 10.9.1.  The drop-shadows surrounding some windows have no gradient or translucency, and in some cases,  Finder windows  show colored pixels in place of the content.  My Mac configuration:  MacBook Pro Model ID 6,2 - Mid-2010 15", Std RAM: 4 GB
    Here is a screen shot, taken the day that 10.9.1 was released (December 16, 2013)
    A workaround that has been posted in these threads [ System Preferences > Energy Saver > Automatic Graphics Switching (off) ] is not acceptable to me, since it reduces battery life significantly.   Also, it is being reported that this workaround works only temporarily, and/or intermittently.
    If you are experiencing this issue, please add to this thread.  There were also reports in the Mac press that this might be one of the issues that Apple was working on for 10.9.1, but apparently not.  Here's one article: http://9to5mac.com/2013/11/15/apple-seeds-first-os-x-mavericks-10-9-1-beta-to-de velopers-with-focuses-on-mail-graphics/
    Here are two other discussion threads that reported the same issue with 10.9:
    https://discussions.apple.com/message/24150281#24150281
    https://discussions.apple.com/message/24150278#24150278
    Let's hope that Apple is monitoring this thread and issues a dot-release quickly, rather than having us wait until 10.9.2.   Apple: please feel welcome to contact me for troubleshooting, if that can help.
    Thank you.

    I'm in agreement with Steve H, on this one.  This is in no way, shape, or form a hardware problem.  This problem was non-existent before the upgrade to Mavericks.  I will be submitting another bug report (translation:  complaint) through the feedback page, and will continue to do so until Apple, in some way, acknowledges that this is a problem and that they are, actively, working to resolve it.  It's beyond ridiculous that there is STILL no fix for this.  I don't know if my problems have been as extreme as other users, but this is still a major nuisance.  The specific issues I, continue, to have are:
    Shadows around app and finder windows rendering improperly
    Dashboard widgets and app icons in the Launchpad are a noisy mess of "static"
    App names in the Dock are just "noise" when moused over.
    These will always occur when the integrated (Intel) GPU is active.  If any of these symptoms crop up, both known fixes immediately, and only temporarily, resolve it:
    Using gfxCardStatus to toggle to the discrete GPU
    Disabling "Automatic Graphics Switching" in the Energy Saver preferences
    Both of these fixes have the undesirable side affect of defaulting to the discrete GPU which is a greater drain on the battery.  This is a band-aid NOT a solution.

  • Shouldn't Apple recall and provide FREE replacement for MacBook Pro screens with ghosting and dead pixel issues?

    Read the forum posts, Google the issue, watch the YouTube videos on the problems; they are everywhere. I purchased a 2012 Retina MacBook Pro and the screen is riddled with dead pixels, white ghosting throughout, and image retention issues, all from a company that promotes the quality of the product they sell. There's no way this issue facing so many consumers shouldn't result in Apple replacing these screens for FREE.
    I purchased the high-end machine for photo and video editing. Photo editing is particularly difficult when I can't tell if I have dust, dirt or colour shifts in my images or if it's just the screen overlaying these issues. I've never had so many issues with any screen I've purchased, from my Panasonic Plasma TV to my cheap ACER laptop. Please Apple, quit ignoring this issue.

    Be advised that this is a user to user forum where Apple employees do not participate.  You may make your thoughts known here:

  • Wierd Pixelation Issue

    I have pixelation on my TV.  It is coming from FIOS, as it does not appear when we are watching DVD's or Roku.  As a matter of fact, it does no happen in FIOS menus, only when watching live TV, recorded programs, or on demand.  There is a band, about 1/3 of the way down the screen, 3 inches wide, that extends half way across the screen.
    Any ideas what may be causing this?  (Sorry the picture is bad)  the pixels do change colors, they tend to bbe the oppsosite of what they should be (white when they should be black etc)
    Mike

    Same Exact Problem here.  Notice it on HDMI and component outputs when I get it.  You do not see it when streaming.  Restarting box gets rid of it on mine.  I have had it three times in the last 3 weeks.  Trying to figure it out myself because I do not want to replace box because I have many, many shows on external hard drive, Through trouble shooting, I am leaning towards external hard drive/esata cable.  I do not get it when external drive is disconnected.  One thing I am currently testing is a shielded esata cable, being so close to the HDMI cable\port,  I do not trust the esata cable I have. Going to swap HDMI cable also. Something messes up the output.  I will let you know results.
    For people having similar issues and troubleshooting, here is what I am using:
    7232 DVR
    2gb external drive (Non-WD/Seagate Pipeline)
    HDMI primary output
    Use Close Caption a lot  (Casual font)
    If you are getting a similar problem, please post your equipment.  I would like to see if any common thread.
    Thanks

  • Sub-pixel issues solved?

    I got my iPod Video less than a month ago. Today, I was watching some Aqua Teen Hunger Force on it and I noticed some pixels were stuck on red, blue, or green. I did a little research and found that means those sub-pixels are stuck on. I did a little searching around these forums and saw a color test from the diagnostic menu. This was quite helpful once I got to the black screen test. The pixels were obviously showing color. Then I accidently bumped the iPod and noticed different pixels were now stuck and a couple of the ones that were stuck weren't anymore. This got me thinking a little so I gave the screen a flick. After a few flicks, viola! No more sub-pixels stuck on, they work normally now. I think this is a rather annoying issue and I would have thought about returning the iPod if they were truely stuck on. I thought I'd say something about it on here though in case anybody runs into a similar issue.

    To remove the coloring completely, use greyscale instead of subpixel rendering.
    However, I would recommend instead finding a compromise you're happy with, e.g. playing with the FIR.

  • FM8p277: Index issues continue...?

    I've discovered that when I include character tags in index markers, the markers are sorted incorrectly-- regardless of the page number, they appear at the end of the entry. Thus, I get something like:
    Topic 15, 92, 277, 150
    where 150 is the page with the formatted index marker. This is pervasive to the point where even index sub-entries will come before the formatted index marker:
    Topic 15, 92, 277
    SubtopicA 151
    SubtopicB 16
    150
    I assume that this is related to the other problems that folks have noted with character tags in index markers. I don't see any recent discussion of this issue-- are others continuing to have similar problems? I'm running FM8 with auto-update, and have the p277 patch. My FM is the version that came with the TCS, though, and I'm wondering if that could affect the efficacy of the patches.
    I'd much appreciate any comments, suggestions, info, etc.!
    Best,
    Melinda

    Sure! <br /><br />The formatting for the index serves to indicate, for a given topic, the location where the reader will find the main documentation on that topic. So the page(s) that have the most basic and comprehensive information are in boldface, while entries that reference the topic more peripherally are in standard type.<br /><br />For example, I have an index entry "Plot Setup." I have references to that topic on pages 289, 302 and 400, and for each of those the text of the marker just reads:<br /><br />Plot Setup<br /><br />The primary treatment of the topic is on pages 317 to 332, and those markers read:<br /><br /><$startrange>Plot Setup<Emphasis><br /><$endrange>Plot Setup<Emphasis><br /><br />So in the index, it appeared as:<br /><br />Plot Setup 289, 302, 400, 317-332<br /><br />I'm also getting this with single-page markers, so I know it's not caused by the <$startrange> and <$endrange>.<br /><br />Thanks,<br />Melinda

  • [SOLVED] firefox3 : huge icons and large fonts with big pixels issue

    hi all,
    i have a weird issue regarding firefox3b3 (and firefox3b4 from mozilla.org as well). Firefox2.0.12 is running fine, but the beta of 3 has insanely huge fonts and icons so big that I cannot use it properly.
    I have removed my .mozilla folder but that did not help, i have reinstalled it, downloaded the true ff3b4 from mozilla.org but all the same problem. On windows and solaris ff3 is running fine. Does anyone know what is doing this and how to fix it? icons are so large that it is even starting to get pixelated. I also tried <ctrl> - and <ctrl>/ and <ctrl>0 but none of those help either.
    thanks,
    stefan.

    i have finally found a solution that Really works on the Ubuntu forum, i still had the same issue on my laptop (why it behaves different from my desktop i dont know, maybe because hwd -xs didnt make a 1920x1200 modeline in xorg.conf) but the following acutally works:
    1) Go to about:config in ff3
    2) Search "dpi". The value may be set to -1 (maybe auto-detection)
    3) Change it to 96 (default dpi)
    4) Enjoy Firefox 3!!!

  • Raw vs sraw hot pixel issue question

    From tests I've come to realize that lightroom processes raw and sraw files differently in Lightroom 3. Hot pixels are automatically removed in standard raw files, but sraw files are not corrected the same way.
    It seems odd that they would not add this as I can't think of any other reason to shoot timelapses in such a large format besides this one serious issue. Sraw is more than large enough, for even a 2k format.
    My question is whether LR4 remedies this issue, or if I need to take a different route?
    Thank you,

    sRaw is no longer a true raw file - it's already been demosaiced.  You could call it 'half-baked'.  So Lightroom doesn't have as much control over things like hot pixels.  Lightroom 4 doesn't change that, sorry.
    An alternative you could consider for timelapse would be to shoot full raw and then convert them to a lower resolution lossy DNG format, at a similar res to the sRaw file.  You'd need extra cards at the time of shooting, but you'd end up with smaller files in the end, and your hot pixels should be removed in the process as LR would have all the data to work with.

  • Sept 2012 Macbook Pro dead pixel issue

    Hi,
    My Macbook pro from Sept 2012 has recently had a major issue with pixels dying, around 10-15 in a few weeks. My Macbook is out of warranty as over a year old so I am wondering what my options are? I don't believe the dead pixels are a fault of my own as I have seen a lot of problems with this issue online.
    Thanks in advance.

    Unfortunately dead pixels cannot be resuscitated.  The solution is a replacement of the display.
    Had you purchased Apple Care, the display, if it was outside the Apple pixel display standards, may have been replaced for free.
    Ciao.
