Horizontal flashing stripes in image

I have the strangest thing in FCP: in fast panned scenes I get a flash of a horizontal stripe, as well in he canvas as in the browser window. It is not in the original image, and it cannot be seen on individual frames either if I look at them one by one. But as soon as I let the clip play, it appears in shots where the camera was panning. Tried the same footage in FCE and there the stripes do NOT appear... Not a big problem, but ennoying when editing. What can this be?

From my own digging, it seems like this has to do with the nVidia graphics cards; I have the same problem. What do you have in your system?

"A graphics problem has been detected" Macbook Pro screen white with horizontal red stripes

This issue arrived out of no where. I'll be using my Macbook Pro then all of a sudden the screen starts glitching and i can't control anything so I'm forced to power off my computer. When I turn it back on the screen will display the Apple logo with a white screen and horizontal red stripes running through the screen (as pictured below). I have to keep shutting down the computer and powering it back on until it asks me to reset my Filevault password then it might work.
After I reset my password it finally restarts and appears to work with the image below displayed on the screen. I spent over 2000 dollars on this laptop, I shouldn't have to wonder if my laptop will work long enough to get something done or have to keep resetting it for days and be computerless. This is crazy! I hope Apple starts paying attention to this issue as I've seen multiple posts about this issue coming for other owners of MacBook Pros from 2011.

The logic board is faulty and will have to be replaced.
Make a "Genius" appointment at an Apple Store, or go to another authorized service provider. You may have to leave the machine there for several days.
Back up all data on the internal drive(s) before you hand over your computer to anyone. There are ways to back up a computer that isn't fully functional—ask if you need guidance.
If privacy is a concern, erase the data partition(s) with the option to write zeros* (do this only if you have at least two complete, independent backups, and you know how to restore to an empty drive from any of them.) Don’t erase the recovery partition, if present.

How can I display more than 15 rows in a stacked 3D horizontal flash chart

It seems I cannot display more than 15 rows at a time in a stacked 3D horizontal flash chart.
Any ideas?
Thanks, Pierre

The default history length of a chart is 1024. To make it longer is a right click option.

Y min value not working in horizontal Flash Bar Charts

Hello All,
Going crazy trying to work this one out.
I have a problem with a Flash Chart (APEX version 3.0.1.00.07)
The data mainly begins at 97 and goes to no more than 100, therefore I want the min to start at 96 so the results don't look to similiar. Why when I imput my minimum value, it does not work for Horizontal Flash charts ?
It seems to work for stack or vertical charts, can something be done via the "custom XML" ?

select option "Same day"

Hi Deb,
Both of your queries are using multi-series syntax i.e. returning more than one series of data, therefore your generated chart is actually generating 6 series rather than just the two that you're aiming for. You could try changing your queries to ensure they each generate a single series of information, which would then result in the extra Y-axis being applied to your "Series 2". Here's an example of what I mean:
Series 1:
select null link, label, value from (
select 'test' label, 1 value from dual
union all
select 'test2' label, 2 value from dual
union all
select 'test3' label, 3 value from dual
)Series 2:
select null link, label, value from (
select 'test' label, 100 value from dual
union all
select 'test2' label, 200 value from dual
union all
select 'test3' label, 300 value from dual
)I hope this helps.
Regards,
Hilary

Can images placed in a slideshow be zero spaced to appear as a rotating strip of images?

I'd like to make a slideshow of images without spacing between the images to make a continuously rotating slideshow strip of images. Is that possible with Muse?

Hi Kenneth,
Use a basic slideshow with vertical transition. By default it has 0 spacing between the images.

Thank you for the update, the fix will be in the release version of Firefox on 2015-02-24.
In the mean time if you want to continue using Firefox beta our Sync service may be helpful getting your Firefox release data into Firefox beta. https://support.mozilla.org/en-US/kb/how-do-i-set-up-firefox-sync

Quad freezes with horizontal flashing

My Quad freezes in several modes; in several programs with horizontal flashing that preceed the freeze. Once frozen, the pointer will move with mouse control but everything else is frozen, nothing responds to the mouse or the keyboard or special key combinations. All I can do is hold the main power button until the machine shuts down. Wait and startup, everything then runs until the next freeze while in one application or another.

Memory problems are very difficult to "catch in the act". But there are some Red lights in your Mac next to the memory slots. Next time it misbehaves like this, open the side door (there is no Interlock and it will not power off if you open the door) and see if any of the error lights are on. That may point to a particular memory module.
There may also be some error messages from the time of the problem in the System Log, which can be inspected with Console utility.

Standard Mac users cannot eject Flash installer drive image

We recently distributed Flash to 130 macs and it defaulted for auto update. Whenever it auto updates, it mounts a flash player drive image to the desktop. Unfortunately all the users are standard users and they cannot eject the mounted drive image without an administrator logon. I have wasted hours logging into each computer to manually eject these drives. How can I reverse this behavior?
We are using apple remote desktop

Hello,
Since your users do not have Admin rights to install software, you'll want to disable auto-updates on each machine. The update settings are stored in the /Library/Application Support/mms.cfg file. You'll want to make sure the AutoUpdateDisable and SilentAutoUpdateEnable settings are configured as follows:
AutoUpdateDisable=1
SilentAutoUpdateEnable=0
This will disable ALL updates for these machines, as such, you'll want to distribute updates via some other mechanism to ensure your users have the latest secure versions when they're released.
Enterprise deployment information is documented in the Adobe Flash Player Administration Guide for Flash Player | Adobe Developer Connection.

Importing into Flash a Fireworks image - advice please!

Importing into Flash using a Fireworks image - advice please!
New'ish to Flash so hope I'm in the right forum ;-)
I have made and image using gradients in Fireworks and have been using FW for ages (please see example below).
I am importing into Flash CS4 this image and want to use it with a Flash component however the image quality is really bad in Flash and I cant figure out why. I have increased the image to 300dpi in Fireworks to see if that helps and it doesn't.
I'm hoping this is a simple thing I am missing due to not knowing Flash as well as I do Fireworks.
Really grateful for any advise. P.

Hi there,
No not trying to adjust size of the image in Flash, do that all before hand.
In Fireworks I can adjust resolution but don't seem to be able to in Flash, is this def the case?

Render flashing over Still images in HDV

I was given this project to rescue, the biggest problem is it is full of still images with moves/keyframes and full of subtitles. The images are all JPEGS, of varying sizes and resolutions, some of them are still in grayscale mode. These problems mainly show up on the interlaced HDTV monitor, on the RGB monitor the images suddenly dip 50% in brightness, and flicker slightly.
The flicker filter on MAX and a gaussian blur will not fix this. the only thing that seems to work is converting all these images to TIFFs and re-doing all the moves which in Final Cut is a nightmare. Here is a link, the full visual dissonance problems are washed out by this camera.
http://www.vimeo.com/5590809
What would be a life saver is finding a way not having to convert all these JPEGs to TIFFs.
Moving keyframes, changing opacity, etc does nothing to improve the render flickering.

The flickering is an artifact of the interlaced nature of video. It is a result of very thin (often horizontal) elements that exist on one scanline as is common in text or titling. This can also be the case in images with great deal of detail with high contrast as well as when when you are engaged in pan/zoom moves on stills.
As the alternate fields play, the flashing element is essentially being turned on/off. The basic strategy is to get the element to exist over two scanlines so it is refreshed every time the field plays or to reduce the amount of contrast so the difference between ON and OFF is not noticeable.
Before you start any of these steps listed below, make sure you are viewing your material on an appropriate monitor. If you are working in an NTSC/PAL interlaced format (eg DV) you need an external TV monitor - not a computer screen. Without the appropriate device, you are playing blind.
Things to try (In increasing order of image degradation)
• (in FCP) field order>none
• (in FCP or Photoshop) reduce whites by 10% - reduces overly bright areas
• (in FCP) flicker filter - minimum
• (in Photoshop) motion blur>vertical> .2 - .5 pixels - blurs vertically only
• (In FCP or Photoshop) Gaussian blur> .2 - .5 pixels -blurs both horizontally as well as vertically
• (in FCP or Photoshop) deinterlace - throws away half the image and is generally not appropriate on scanned images
Remember: Unless you are viewing your work in the appropriate external NTSC/PAL monitor, you are playing blind. The computer monitor only shows you a proxy image.
One final thought, if you have slowed your material significantly, and have not used some sort of frame blending/optical flow processing, you may be simply duplicating frames to create the additional material to pad the playback. The flashing you see is the result of this.
good luck.

Can you help me fix my screen? It randomly has a bluish tint, bad resolution and horizontal flashing lines

Hi all,
It's a 15" 2.4 Ghz Intel Core 2 Duo MBP running on Leopard 10.5.8, bought spring 2008.
About a couple of weeks ago, my screen started randomly switching to a strange blue / purple tint along with a bad resolution (can't really read text on screen) and flashing horizontal lines in the background. It started worrying me given I'm working with it all the time and am hoping for this machine to hold on for a few more months until I can buy a new one.
It would happen randomly for a few minutes at a time and then revert back to normal screen.
I found a lot of references to a similar problem in a few threads such as this one:
https://discussions.apple.com/thread/1456983?tstart=0
My screen has gone strange again now and isn't reverting back to normal so far even after I tried restarting it. It was normal for 2 min only ans then back to bluish. I tried all the display fixes indicated in the threads but none of them work and I'm not exactly sure my issue is the same given I can still see the tint and horizontal lines in particular if the screen saver goes on, and the resolution on screenshots I've seen of other people having blue tint screen issues seems to be normal (as in text is legible).
Any ideas on how to fix it? Do you think it might be more of a software or hardware problem..? Would it help if I try upgrading my Mac OS?
Thank you very much for your time

Thanks a lot for the reply, I was worried would say that outright. Screen just only reverted back to normal after a couple of hours. As you said probably best to bring it in for diagnosis, I'll try to do that asap though of course I'm nowhere neaar any AASP at the moment.

Flash files as images in XML Forms

Hi Crew,
Anyone had to use flash files in XML forms Based Publishing?
Have created a simple XML Project asking the user to select two images, and these are then displayed in an iView.
gifs & jpegs display no problemo. swf (flash files) do not.
Any ideas?
Paul

Hi Paul,
I need to display a .swf file in a XML form. I read the solution that you have posted about modifying the XSL file, but i have no clue how to go ahead with this.
Could you kindly provide any document, link or the solution as to how to modify the XSL file ?
Any kind of help would be truly appreciated.

Flash Player Renders Images Differently in Browser than Stand-alone Player

Hey, guys!
Not sure if this is a Flash issue or a Flash Player issue, but here we go...
I`m currently working on a Flash project with a great deal of images.
Flash does a great job compressing images, but in some cases it messes up the colors.
I have a big image on the background and it`s set to 80 compression from the Properties panel.
Everything looks fine in the stand-alone Flash Player when exporting from the IDE or even opening from disc, but when I insert the SWF in a HTML page (with SWFObject, dunno if it matters) some werid artifacts show up, and also the colors get shifted to slightly different values (I can tell since I have a background that should match the SWFs background!)...
There is a workaround, though. Setting compression to Lossless... Then everything looks EXACTLY the same both in the stand-alone player and in the browser. Just that you end up with a 900 kilo image instead of 200 and something... :|
And if you have several images that have to be treated "Losslessly", you end up with a pretty big SWF!
My other workaround was to sample the colors in the browser and modify the ones in my CSS for the HTML background.
That works well for the colors, but I still end up with some ugly artifacts, even when compression is set to 100!
And, again, the strange thing is that in the stand-alone player, everything is honkey dorey, the colors and all!
NOTE: the project I`m working on is a Flash 10 file, ActionScript 2, if that would matter...
Thank you for your time and I appreciate any suggestion/explanation!
Alex

i've had a problem before with the fps and a mac.
how big is your file?
i usually make my movies around 24 fps to keep load off of
the cpu which could make it run slower
