Flickering when downconv HDV to DV

I had some problems while trying to downconvert HDV material to DV. System is based on macpro with Decklink HDExtreme and Sony HVR1500. Material is captured in ProRes 422, rendered and when printed to tape, trough SDI some flickering occurred, as well as trough fiwi.
Is there a solution for these problems ...

OK. This is a dayly business, for about 9-10 years. Experience? Have some. That drives me crazy. It is the matter that I've got a new pice of equipment and together with my colleagues I made a decision to make a transition to HDV (that can be problematic decision). It worked properly while we were using Sony HD tape HVR15U with FiWi, but recently we purchased HVR1500, as a robust and hi end solution in HDV segment.
New machine - new problems.
So until now we were working with fiwi and downconversion from HDV to DV PAL during capturing, now our strategy is to capture everything in HDV via SDI using Pro Res 422 codec, to work with it (in order to keep quality), and to convert it to DV PAL on exit via SDI (while printing it to tape). And we have flickering problems. Both trough SDI and FiWi.
I think I mention my oppinion about solution recently but I'm not sure and I can not explain that.
I asked a people that are in Sony rep office, they got no idea ... So, .... still searching ...

    Hi,
    Check the cable connections and make sure that they are tight.
    Try a different monitor and cable to separate the monitor and cable from a possible PC issue. Alternatively, try the monitor and cable on a different PC.
    Does the monitor behave the same way when it is has warmed up?

  • Monitor flickers when screen saver runs

    I have a two monitor setup.  I just put in a replacement video card which has one ADC port and one DVI port.  The monitor on the ADC port flickers when the screen saver runs.  But it doesn't seem to flicker at any other time.  The monitor on the DVI port has no problems. 
    I wonder if there's anything I can do to get rid of the flicker.  Could it be the card, which otherwise seems to work fine?  Or could it be a memory problems?
    Any thoughts appreciated!

    I wonder if it is the screen saver. Some really put the 3D graphics hardware to task. Have you tried switching to a screensaver that doesn't demand serious hardware acceleration like "Computer Name" or one of the "canned" savers that display picts like Cosmos, Beach, Paper Shadows, etc?
    I keep two different types of temp monitoring on my Macs so see what programs task the system, One is software and the other is a direct-read remote thermometer (remote sensor tucked in the exhaust port of my Intel iMac). When I run the 3D savers, I can see the temps start to go up.

  • Since installing the new update videos keep on flickering when I stream them. How can I fix this?

    Ever since I updated Firefox the videos I watch keep on flickering when I stream this. It is true of youtube, and other mediums. This is not a problem when I watch videos on Safari or Internet Explorer. I have uninstalled and reinstalled firefox to no success and restarting my computer has not helped either.

    Hello, if the Flash player is not up to date, please update it, aslo:
    Some problems with Flash video playback can be resolved by disabling hardware acceleration in your Flash Player settings. (See [[Flash Plugin - Keep it up to date and troubleshoot problems|this article]] for more information on using the Flash plugin in Firefox).
    To disable hardware acceleration in Flash Player:

  • My Macbook Pro display flickers when using power adapter

    I purchased a new power adapter for my Macbook Pro (late 2011 17 inch) from Other World Computing and now the display flickers intermittently when attached to the new power adapter. There is no flickering when not attached to the power adapter or when attached to the old power adapter.
    Any ideas on fixing the new power adapter? I would rather fix the problem if it is simple.
    Thanks for the help.
    Roy Patience

    It doesn't affect the battery. You can use your MacBook Pro plugged in all the time without damaging the battery. You only have to be sure that you unplug it and run a battery cycle (drain the battery without letting the Mac turn off and charge it fully) at least once a month to keep the battery life.

  • Firefox: Flickering when scrolling - need help with clean 'new' install

    Screen is flickering when scrolling (IE does not). I tried disabling add-ons and tried safe mode - neither helped. Running Win 7 Pro 64bit. Uninstalled via 'Programs and Features'. Download and reinstalled Firefox. Now it shows all my previous settings: menu bar, bookmarks bar, etc. Question: how did it get that stuff back if it 'cleanly' uninstalled? Question: how do I know it didn't pick up it's old 'bad habit' from the previous settings? I am an experienced PC user but not Firefox expert. Looking for help lest I have to ditch Firefox completely...

    Hello,
    Try disabling graphics hardware acceleration. Since this feature was added to Firefox, it has gradually improved, but there still are a few glitches.
    You might need to restart Firefox in order for this to take effect, so save all work first (e.g., mail you are composing, online documents you're editing, etc.).
    Then perform these steps:
    #Open Firefox ''Options'' window (''Preferences'' on Mac or Linux) as follows:
    #* In Firefox 29.0 and above, click the menu button [[Image:New Fx Menu]] and select ''Options'' for Windows or ''Preferences'' on Mac or Linux.
    #* In Firefox 28.0 and previous versions, click the orange Firefox button at the top left, then select the "Options" button, or, if there is no Firefox button at the top, go to Tools > Options.
    #In the Firefox Options (or Preferences) window, click the ''Advanced'' tab, then select ''General''.
    #In the settings list, you should find the ''Use hardware acceleration when available'' checkbox. Uncheck this checkbox.
    #Now, restart Firefox and see if the problems persist.
    Additionally, please check for updates for your graphics driver by following the steps mentioned in the following Knowledge base articles:
    * [[Troubleshoot extensions, themes and hardware acceleration issues to solve common Firefox problems]]
    * [[Upgrade your graphics drivers to use hardware acceleration and WebGL]]
    Did this fix your problems? Please report back to us!
    Thank you.

  • Image flickers when repainting

    Hello,
    I'm trying to make an applet where a line moves sideways as the slider is moved. The code below is working but the image flickers when repainting:
    import java.awt.Graphics;
    import java.awt.Color;
    import java.awt.Scrollbar;
    import java.awt.event.*;
    public class testSlider extends java.applet.Applet implements AdjustmentListener {
      int w, h; // Applet width and height
      Scrollbar sb;
      boolean scrollChanged = false;
      int xUnit, yUnit;
      public void init(){
        //field variables initialization
        w  = this.getSize().width ;
        h  = this.getSize().height ;
        xUnit = (int) Math.round(0.1*w);
        yUnit = (int) Math.round(0.1*h);
        sb = new Scrollbar(Scrollbar.HORIZONTAL, xUnit, 1, xUnit, 9*xUnit);
        //add Scrollbar
        sb.setBounds(5, 9*yUnit,this.getWidth() -15, 15) ;
        this.setLayout(null);
        this.add(sb);
        sb.addAdjustmentListener(this ) ;
      public void paint(Graphics g){
        System.out.println("paint...") ;
        g.setColor(Color.GRAY ) ;
        g.fillRect(0,0,w, h);
        g.setColor(Color.BLACK) ;
        //set new Origin
        g.translate(w/2, 8*yUnit) ;
        if (scrollChanged ) {
          g.setColor(Color.YELLOW  ) ;
          g.drawLine(sb.getValue()-w/2, -7*yUnit, sb.getValue()-w/2, 0  );
      //AdjustmentListener method override
      public void adjustmentValueChanged(AdjustmentEvent e){
        scrollChanged=true;
        repaint();
    Can someone tell me how to prevent this flickering?
    Thank you very much.

    g.fillRect(0,0,w, h);This needs to modify quite a few pixels so it is going to be on the slow side.
    Try this: store the coordinates of the previous line you drew. When repainting, if you have drawn a line previously, first draw the old line with the background color, then draw the new line, and finally store the coordinates of the new line so you can paint over it later.
    I haven't tried that myself though.
    An alternate is to use double buffering. Google: java double buffering. But that may be slowish and CPU intensive because that too needs to touch a lot of pixels.

  • JTable Flickering when you scroll Browser Window

    Hi All,
    I am using JTable. I am having this annoying Flickering when I am trying to scroll the Browser Window. For example if I have 4 or 5 table in my page and it will exceed the browser size. If I want to see all the tables, i have scroll down to see. When I scroll, the table is Flickering and it becomes white and then only I am seeing the Table. Some times the whole table is destroyed by the flciering and then i am getting the table. This very annoying problem i have. I am writing all the code to draw the table in "init()" method of my JApplet. Please help me whether any solution is there for this.

    This is a bug in Java 1.3 (Bug IDs: 4314208, 4337823), which uses a new fast DirectDraw accelerated scrolling algorithm which sometimes screws up (I think I read it's a thread race condition) and garbles the text. You can switch to another scrolling method, which won't mess up, but will draw slower. Use this code:
    myJScrollPane.getViewport().setScrollMode( JViewport.BACKINGSTORE_SCROLL_MODE );In the application I am working on, I have extended the JScrollPane to a new class which tracks all instances of itself within an internal static Vector of WeakReferences, which allows me to change all the scroll modes at once, then I have a user preference so users can switch to the slower mode if they are experiencing problems.
    Alternatively, you can turn off Java2D DirectDraw acceleration with a VM paramater when you start your program:
    java -Dsun.java2d.noddraw=true {your-app}

  • T400 Screen flickers, when I connect power adapater in my home

    T400 Screen flickers, when I connect power adapater in my home. When I connect the same power adapter in my office. It works fine. Can any one please suggest me, what's the issue with the T400 laptop. If it's a issue with my power supply in my home , how all other computers are working.

    Hi Snowfall,
    Have you resolved your flickering issue? It looks like I have the same on my Ideapad Y550P. Screen flickers occasionally when I work connected to the power adapter at home. And what is more concerning is that the brightness control also stops functioning sometimes.
    In your case how has the situation evolved? Has your laptop been repaired or you just live with it as is or has the issue deteriorated into something worse? Just want to get some arguments in my discussions with the SL2 support who cannot reproduce the problem in their office...
    Any extra informaton is much appreciated.

  • Photoshop CS6 - Screen flickering when using brushes with new MacAir 2013

    Would the Adobe team please respond to the issues reported by several users:
    http://forums.adobe.com/message/5449199
    A number of users experience severe screen flicker in Photoshop CS6 when using any of the larger brush type tools (cloning, eraser, brush, spot healing, burning, and dodging).  As many on this thread are experiencing, it is awfull and unusable! The flicker is screen wide black boxes, sometimes the whole screen goes black.  It only seems to happen when we put the cursor over the image to edit.
    Hardware:  MacBook Air 13", Haswell 1.7 GHz, 8GB, 512 SSD Software:
    Photoshop CS6 v13.1.2 20130105.r.224, OS X v10.8.4 (and perhaps others)
    Looks like a CS6 is not compatible with teh new MacAir. Please look into this and advise.

    An update:
    I went to the Apple store and brought myself a more recent MacBook Air (13", 4/256 FYI, they were out of the 8/512 model).    I can't reproduce *exactly* what you're showing, but got the flicker to happen by resizing the cursor.    Also, while painting, the screen seems to stop updating except for the cursor -- not only is Photoshop unable to draw, but other applications stop drawing as well.  And a few times it hasn't even updated the cursor (while all other apps seem frozen).  That's not normal.
    When I see the flickering, I frequently see the menubar and other UI elements draw at the wrong location on the LCD, then black, then redraw in the correct location -- repeat in different positions and lots of "static" until I stop changing the cursor.  That's more evidence of a hardware or and odd driver issue.  The odd thing is: it doesn't happen all the time.  It's possible that the one we have at the office also shows the problem, but we didn't test long enough.
    I'm trying to reach out to my hardware contacts at Apple - but it's a weekend before a holiday, so we may not make progress immediately.
    One thing that would be useful here: the model of MacBook Air that you have that shows (or doesn't show) the problem.
