Flicker free or de-interlace

Howdy...
I have been working a project that has several still images with motion. I have read about the de-interlacing filter but what about the flicker filter. I dont see that mentioned much. Is there a difference?
Thanks for the advice...
Troy

You will notice that the Flicker Filter, as well as being on its own, is also bundled with the De-interlace Filter.
I'm not sure but I think the Flicker Filter may just blur the fields slightly rather than removing one.
Anyway, don't pay too much attention to what people say - do your own test, using all of them, to find what gives the best result for your particular circumstances.

Flicker free or de-interlace filter

I can't seem to find a flicker free or de-interlace filter?

moze, that's correct.... the project (timeline) needs to remain interlaced. I've placed a few lower thirds which were created in PS and imported as png.
Doing this in FCP 7 I'd then add the "Flicker Filter MAX" filter which eliminated flickering when played back on a interlaced TV.
hafken - Thanks for that advice, I've only just bought the Ripple Traning Motion 5: Rigging & Publishing Titles, Transition, Effects & Generators for Final Cut Pro X, so I'll go through that and try work this out.
Cheers to all once again.

Flicker free page updates with JSF?

My JSF app is running but there's flicker when I click the update button to get my search results. I basically forward my page to its self in the faces config file, so I figured this would happen.
<navigation-rule>
   <from-view-id>/Inputname.jsp</from-view-id>
    <navigation-case>
     <from-outcome>greeting</from-outcome>
     <to-view-id>/Inputname.jsp</to-view-id>
   </navigation-case>
</navigation-rule>ICEsoft offers extensions to solve this by using AJAX, is that the only way to achieve flicker free operation?

Hi,
I'm doing that using the same config and it works fine.
Ajax is a brand new solution. MyFaces provides tag to use it easily.

Duke Pt avail. 2nd time askin, (Flicker-free background) Simple Animation

2nd time askin, since didn't get sufficient help. Duke Pts available! I am trying to create simple animation on a solid constant background. I used double buffering for moving the object and it works fine. But the problem is with the background image. The image seems to flicker while the object is moving. Here's my code:
import java.awt.*;
import java.applet.Applet;
public class changed extends Applet implements Runnable{
Image buffer;
Graphics bufferg;
Thread main;
int x=0;
boolean flag=false;
public void init(){
setSize(500,500);
main=new Thread(this);
main.start();
buffer=createImage(getSize().width,getSize().height);
bufferg=buffer.getGraphics();
public void run(){
while(main!=null){
try     {
main.sleep(50);
catch(Exception e){}
repaint();
public void stop(){
if(main!=null){main.stop();}
public void paint(Graphics g){
update(g);
public void update(Graphics g){
Dimension d=getSize();
bufferg.setColor(getBackground());
bufferg.fillRect(0,0,d.width,d.height);
bufferg.setColor(Color.red);
Image img = getImage(getCodeBase(),"bliss.jpg");
if((x<500)&(!flag))
bufferg.fillRect(x+=5,10,25,25);
else
flag=true;
bufferg.fillRect(x-=5,10,25,25);
if(x==0)
flag=false;
g.drawImage(img,50,50,this);
g.drawImage(buffer,0,0,this);
Please help me with this minor problem. I think what's happening is that the background is been drawn over and over again. I don't know how to make it constant and flicker-free.

Possible 2 things:
1. You're reloading the image on each repaint:
Image img = getImage(getCodeBase(),"bliss.jpg");You shouldn't do that, you should just load it in init.
2. You're drawing the image with the non-buffer Graphics "g" instead of "bufferg." You should use bufferg and draw it before anything else.
I've modified the code for you, it should work but I can't test it because I don't have bliss.jpg. Let me know if it doesn't work.
Here's the modified code:
import java.awt.*;
import java.applet.Applet;
public class changed extends Applet implements Runnable {
     Image buffer,img;
     Graphics bufferg;
     Thread main;
     int x = 0;
     boolean flag = false;
     public void init() {
          setSize(500, 500);
          img = getImage(getCodeBase(), "bliss.jpg");
          main = new Thread(this);
          main.start();
          buffer = createImage(getSize().width, getSize().height);
          bufferg = buffer.getGraphics();
     public void run() {
          while (main != null) {
               try {
                    main.sleep(50);
               } catch (Exception e) {}
               repaint();
     public void stop() {
          if (main != null) {
               main.stop();
     public void paint(Graphics g) {
          update(g);
     public void update(Graphics g) {
          Dimension d = getSize();
          bufferg.drawImage(img, 50, 50, this);
          bufferg.setColor(getBackground());
          bufferg.fillRect(0, 0, d.width, d.height);
          bufferg.setColor(Color.red);
          if ((x < 500) & (!flag)) {
               bufferg.fillRect(x += 5, 10, 25, 25);
          } else {
               flag = true;
               bufferg.fillRect(x -= 5, 10, 25, 25);
               if (x == 0)
                    flag = false;
          g.drawImage(buffer, 0, 0, this);

Flicker free / No PWM backlight laptop

Hi,
I would like to know if MSI produces any laptop with a screen that doesn't use PWM for dimming. Ideally with 15" display but 17" would be acceptable too.
For some reason, the screens with LED backlights that use PWM, produce me severe eye strain and nausea. It's not something usual, but it seems I'm not the only one with this problem.
PWM explanation: http://www.tftcentral.co.uk/articles/pulse_width_modulation.htm
Thank you

Hi,
Thank you for your answer.
It wouldn't be very practical to test the screen by myself going to the shop. Symptoms use to appear after 20 minutes of using the computer and also, I would only be able to test one laptop per day. I could use an oscilloscope but I, have none and also, I think they are a bit too bulky to bring them to a shop.
Quote
You can increase the brightness to the maximum value to decrease the frequency of PWM and then dim it with some kind of external filter films to decrease the brightness.
That's an option but I still cannot be totally sure the screen will not flicker at 100% brightness.
I guess it is not a good time for people that need to work with computers and have flicker sensitivity.

Flicker free screen / IFrames issue

Hi all!
We're using WAS 6.40 and NWDS 2.08 to build web dynpro applications. We want to use iFrames in order to show some BW reports, and this works nicely except for one detail (important one though). The iFrames reload on every single action made in the application, and we're looking for a solution for this. Apparantly, since SAP made the decision to go for Server Side Rendering, this seems to be an effect, because when we used the sneak preview (2.0.2 or something similar) all worked fine!
Does anyone know of a solution to this matter. As we present the WD apps in our EP 6.0 I guess we could construct pages with one WD iView and one Portal iView (showing the report/web page) but this wouldn't look as integrated and nice.
B.R
Andreas

Bad news Andreas -- it is a known issue with no resolution up to date (or up to the most resent SP10)
Search these forum and you'll see that this question arise for several times.
Also problem is described here /people/jochen.guertler/blog/2004/11/12/web-dynpro-best-practices-how-to-combine-your-web-dynpro-application-with-existing-non-web-dynpro-content
The only workaround is to place report outside WD Component and use 2 portal iViews to display WD content & BW report separately.

Severe flicker or interlacing artifacts with motion

In the archived topic with the same subject as this one at:
http://discussions.apple.com/thread.jspa?threadID=351090&start=0&tstart=0
my problem with interlace flicker was not solved. There is bad news and good news with the new iLife '08.
*Bad news*: iMovie HD 6.0.4 still generates flicker with the new iDVD 7.0.1.
*Good news*: iMovie 7.1 +does not+ generate flicker with the new iDVD.
This means the source of the problem was not EyeTV or its export settings, or the old iDVD. It was iMovie all along.
Of course, the new iMovie has a long way to go to catch up with the old iMovie and I seriously doubt if we'll ever see any updates to, what should I call it now, *iMovie Classic*, but actually being able to build a flicker-free movie is certainly worth something.

Interesting. I want to try the workaround ElPresidente suggested in that archived thread. Lots of good info in that thread.
I too am having this problem although I'm calling it "jitter".. See this thread:
http://discussions.apple.com/thread.jspa?threadID=1166111&tstart=0
I'm using iMovie HD and iDVD 5 and EyeTV 250 plus.
I'll follow this thread too.

De Interlace question for flicker???

I have frames that I made into freeze frames and they flicker. Also some slow motion that flickers
1. Which of the De-interlace settings solve this problem?
1a. is there a different setting for the freeze frame shot and the slow motion shot?
2. If I have a lot of shots can I select all and apply all at once?

If your clip flickers, try using the Filter: VIDEO- FLICKER FILTER as well as DE-INTERLACE.
For all slow motion shots (if shot on 29.97 FPS - NTSC) you should be using flicker removal and de-interlacing filters to smooth them out.
Create a nest and apply those filters at once on all your clips

Field Dominance and De-interlacing: what settings to use?

I've been trying to read about, and understand, the issues of deinterlacing and field dominance/order, but I'm having problems and don't yet see what the clear solution is.
I'm shooting DV footage with a consumer grade camcorder:
Capture Preset: DV NTSC 48 kHz
Sequence Preset: DV NTSC 48kHz
720x480 NTSC DV
QT Video Compressor: DV/DVCPRO-NTSC
The problems are "teeth and vertical lines" in the quick movements and transitions, but fixing one (by changing the "Field Dominance" setting in the Sequence) makes the other slightly worse, it seems.
Or, maybe I should be using the de-interlacing filter on everything? I haven't found clear instructions about what destination material this should be used for...
I'd be grateful if someone could look at this web page containing examples of what I mean:
http://www.karma-lab.com/images-pub/apple-q/fielddom_nt.html
Picture 1: NTSC DV frame, from sequence set to "Lower (Even)"
Picture 2: NTSC DV frame, from sequence set to "None"
Picture 3: frame from "Cross Zoom" transition in "Lower (Even)" sequence
Picture 4: frame from "Cross Zoom" transition in "None" sequence
Questions:
1) What are the correct settings? it would seem to be "None", because otherwise my transitions all have "teeth" and look like somebody is viewing it cross-eyed, even at full speed you can see the teeth in the transitions. But if I set it to none, then it seems that quick movements of the people in the videos get slightly more "teeth" to them...
2) I am producing web video (quicktime/flash video movies). Not for TV or broadcast. Am I supposed to throw the de-interlacing filter on everything?
with "lower", it's jerky (half the frames missing, I guess) but the "teeth" go away
with "flicker-free", it's not jerky, but it gets a little fuzzy looking, and I want to keep things "crisp"...
I need less advice on the theory, and more advice on "set it like this for what you are doing." I've read some really technical explanations, and I understand why interlacing exists etc., but not exactly what I should be doing to get the optimal results for my needs, i.e. simply good-looking web video with decent motion and transitions, shot from a consumer level DV camcorder.
Thanks for reading!

What are the correct settings?
Since you mention that you've shot your material on a consumer-grade camcorder, that would mean that Field Dominance – in your FCP Sequence Settings – should be set to Lower. If you use None – and I'm sparing you the tech talk here – then you're basically rendering out at a reduced quality (as the last pic in your link demonstrates)

If you really want to keep things crisp, you best quality option - within the Final Cut Studio suite of tools - is to Export Using Compressor, with the Deinterlace option in Compressor 2.x's Frame Controls to Better (Motion Adaptive) while setting your Output Fields to be Progressive (presuming that you'll exporting to QuickTime first, then converting to Flash. Having said that, this type of conversion can take a long time to process and may not be suitable if you're under a serious time constraint.
Otherwise, the speediest option is indeed to slap a Deinterlace filter onto everything (or nest your sequence then place the filter on the nest) but the quality isn't always what folks would like.

I have just fixed my screen flicker (Software only)

First of all, please note the below procedure is to be tried at your own risk.
The basic idea is to add a custom refresh rate to the system (70Hz Vertical) and use it instead of the default one (60Hz).
What was my flicker like:
Continuous, felt like watching and old TV (European, 60Hz) and feeling the ripples. I had no sudden changes of backlight intensity, and the flicker became obvious when using a matte background image, usually grey or blue.
What I had done:
While searching for any clues on how to check/modify the display refresh rates, I found a thread (really sorry for not putting the link ... forgot it) where the poster recommended a small program (SwitchResX Control) to create a poll of faulty LCD manufacturers. I have downloaded the software and finally I managed to fix my flicker
Step 1:
Get the program at http://www.madrau.com/switchres/SwitchResXControl.zip. You should use the native resolution for the MacBook (1280x800).
Step 2:
In the program, go to the Custom tab. Press the + sign to create a custom setting. In the 'Timing Parameters' window, after making sure all the parameters are the same as the normal 1280x800 setting, set the vertical scan rate at 70. Also, check the 'Positive synch' check-box. Save everything and reboot.
Step 3:
Open System Preferences, then Displays. Now you should have the Refresh Rate drop-down option enabled (should be 60). Select the 70 setting. Save and reboot.
Step 4:
You should have a flicker-free display now.
Feel free to check http://www.iedutu.net/macbook for pics taken during setup and settings from my machine.
Please remember:
0. If anything goes wrong, select Factory Settings, save and reboot.
1. This thing worked fine for me. It might not work for you. If you have done all steps and still have a flicker, you might have a genuine hardware problem. Like I mentioned before, I did not have an extreme type of flicker, nor a random one.
2. This should be tried at your own risk. I think setting a different refresh rate cannot damage your hardware, but I'm not a hardware guy, therefore I hope nothing will go wrong with my MacBook too .
Have fun!
Cristian

I looked over a number of mac forums and I can say that there are two separate flicker problems:
1. Continuous flicker, obvious on a blue/gray wallpaper when dimming the brightness. Flicker not visible on full brightness, growing while dimming the display. At 50% brightness the display is very usable, flicker visible only if you are actually looking for it. My take this is a software problem (found few people saying the flicker is gone in Windows XP in bootcamp, but present in OSX).
2. Random flicker, ranging from almost visible to flashing screen. Comes at random times, with or without the power adapter plugged in. Can appear in all sorts of combinations/situations. I do not want to assume anything here, but I feel this is a hardware problem based on the YouTube clips I saw.
My case was the first one, thank God and hopefully it will stay like this, although I saw MacBooks on display with no flicker whatsoever.
On the second case, I think a trip to an Apple Service Center would fix it. Unfortunately there is no known faulty module that changed is fixing the problem for everyone with the random/continuous flicker. Everything from logic boards to invertors to displays were changed with mixed results. But it seems the invertor is being changed in most cases and most people are happy with the result.
My 2c.
Have a nice day!
Cristian.

Why does my screen flicker every 10-15 seconds?

Why does my screen flicker every 10-15 seconds?

like a blinking? do you have the late 08 MBP?
if so go to system, energy saver, and select better performance. Your screen should be flicker free.

Video Playback Flicker Windows 7/8 Media Center? Disable Intel Dynamic Contrast to stop it

If you bought a Mac Mini for use as a Windows Media Center DVR Computer like me, you'll notice a background flicker on live tv or recorded tv.
Mine is the Mac Mini (Late 2012 Model) with Intel HD 4000 Graphics
If you go into the Intel Graphics and Media Control Panel. (icon in lower right) Go to Graphics Properties, Advanced Mode, Media, Image Enhancement, and UN-check the box for "Adaptive Contrast Enhanscement"
Video will then be flicker free! (aka 29/59 bug)
Here's a video that walks you through it.
http://youtu.be/9g6Z1sWOOIA
Also, if you have white snow, or video blank outs their is a firmware update for the Mac Mini 2012 model itself. I use Boot Camp, so my Mac OS X Mountain Lion side could update things when needed. (but leave the machine running 99% of the time in Windows 8 as my DVR)
I learned this from:

Solved the Minecraft flicker issue

SOLVED!
Was having an issue with the intel HD4600 graphics driver flickering every time my son played minecraft. Got a hold of a wonderful HP support guy in India and he and I worked it out.
1. Uninstall the Intel 4600 Driver fom device manager
2. Uninstall java
3. Increase the virtual memory on your computer as much as you can
4. reboot
5. from device manager on the graphics card do the "check for updates" or "update driver". Follow the process until it updates to the intel 4600 from the microsoft standard display adapter (what is interesting is that when it did this on my new pc, it acutally rolled back the driver to a previous version, NOT the version that shipped when I received the PC)
6. Reboot
7. reinstall java
8. reboot
9. Click minecraft and play.
Hope you avoid the time wasted that I had before I finally got through to a real technician in India.
Also you should know that the text "chat" support from HP is horrible. The person there told me that minecraft was just incompatible with my pc. Which obviously it isnt, as my son is now playing it flicker-free.

More questions and thoughts about Anti-Flicker

I am working on a video that consists entirely of digital photos provided by my client (all jpgs - not my decision). Many of them flicker terribly in the final video. I did a search for "anti-flicker" on this forum and read a number of threads about it. There is one thing I am experiencing that I do not believe was covered in any of those threads.
First of all, selecting "flicker removal" in a clip's field options is useless. I don't know why this should be so, since this worked very well in Premiere 6.5 (my previous version).
However, adjusting the anti-flicker filter in the motion settings works great when one renders a preview. But this seems to have no effect on the final video output, and strangely, all the anti-flicker settings reset to zero if I exit the program. This seems like a bug to me. Does anyone else experience this?
Here is my work around. If I also make an adjustment to the scale of the clip, then Premiere will remember the anti-flicker filter setting, and the final video output is flicker free. If my photo is already sized for the screen, I'll set a scale setting of 99%. If the photo is large, I will either resize it in Photoshop, or uncheck "scale to frame size" and resize it with the scale adjustment.

Thanks for your reply
The forum is called "support" so i thought there should be some admins and technicians of nokia itself on the forum...
I send my request direct to nokia, although i am sure that there will be no change of thinking in future. A mobile, especially a music mobile, should be able to do that. That way it works now it will never challenge a iphone or ipod, i think.

Footage seems to flicker

Hi
I've been having a problem with footage that I have imported into AE CS3. I have captured the footage using fraps (I'm creating machinima) and after editing the clips together in sony vegas I exported as an AVI and added it to after effects.
My problem is this: When I look at the footage in AE small dots appear to flicker on the textures and static shapes seem to move. The flickering is constant, frame by frame. When I added the footage to the composition however it was fine. But when I now export my project the flickering has returned. Can anyone help me?

Footage interpretation is done in the project panel using the righ-click menu. since you captured from a realtime engine, the frames should have no fields at all and be interpreted as such. For generating clean, flicker-free fields the framerate would have to be double that of the output, e.g. 50 fps to generate a 25fps PAL version. For anything else you will simply have to accept the limitations of realtime content like swimmming textures or non-antialaiased geometry edges that will show up on video, but be barely noticable on your high-res computer screen during capture.
