Dark "scan lines" across finished movie frame

I'm trying to put together a movie from still photos and recorded audio. It needs to be output in 1024x780 pixel format to match the projector used at a multimedia show. All the images were taken with a 8 megapixel digital camera, and I have used PhotoShop to format them as 1024x780 prior to dropping them into iMovie. Everything looks good in the iMovie timeline editor, however when I compress the finished movie using Expert Settings into the final format, I get thin horizontal black lines across the frame that breaks the image into many thin horizontal bands. I've tried switching to other codecs to see if I can make the problem go away, but anything that can produce the finished movie in something other than standard video format causes the same problem. The only thing that seems to work is letting the program make the movie in standard video format, such as making a .avi file instead of a .mov or a .mp4 out of it, but then I don't have a full-frame image for the projector at the show, which is necessary.
The show producer says this is a generic Mac iMovie issue and he wants me to switch to PhotoPro on an Windows XP machine. Surely this isn't true and there is a fix to this problem.
Ideas anyone?

Eep, I'm so sorry, I just realised I posted this in the wrong forum.. I don't know how that happened o_o
I'm actually using Adobe Premiere Elements 9 - Is there any way to move this thread or should I just make a new one? I suppose the questions are still relevant though?
I'm using Procaster from livestream.com to capture videos
With G-Spot:
The source file doesn't have these lines though
I have no idea how to find the sequence settings but maybe that's because it's a Pro thing rather than an Elements thing?
As from what I can see, because it's sped up, it's actually merging 2 frames (so alternating the lines from each frame?) when I'd rather it just drop one frame

Reader X prints black line across page 1

Just started using Adobe Reader X, which I really like. However, it will not print properly, and puts a couple dark black lines across the page.
Any help would be appreciated.

Back up all data. Don't continue unless you're sure you can restore from a backup, even if you're unable to log in.
This procedure will unlock all your user files (not system files) and reset their ownership and access-control lists to the default. If you've set special values for those attributes on any of your files, they will be reverted. In that case, either stop here, or be prepared to recreate the settings if necessary. Do so only after verifying that those settings didn't cause the problem. If none of this is meaningful to you, you don't need to worry about it.
Step 1
If you have more than one user account, and the one in question is not an administrator account, then temporarily promote it to administrator status in the Users & Groups preference pane. To do that, unlock the preference pane using the credentials of an administrator, check the box marked Allow user to administer this computer, then reboot. You can demote the problem account back to standard status when this step has been completed.

Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.

Dark line across white menu bar space

Something really weird just happened. Across the white menu bar (where it lists Finder and shows the clock, etc) there is now a somewhat faint black line. it's a few cm thick, and looks a little blurred. This is what happened prior to the line appearing:
I was downloading the latest update to Quicktime
I was trying to transfer a song from my iTunes library, as well as a video, to my iDisk.
I was adjusting the brightness of the screen.
The iDisk locked up... it said there was 5 secs. left of the transfer. Also, the updater said I had to restart the computer. I did this, but when I restarted the screen was really dark. I was playing with the adjuster, and the screen went black. I restarted again, and the brightness was ok... I still had to adjust it to make it lighter.
Now everything seems to be working ok (except my iTunes music file and video say they are in use by OSX and cannot be opened... I just deleted them)
but I have this crazy line across the top of the screen.
Please help?

Hey, thanks everyone. I am running Tiger on my iBook... I have Panther still on my iMac, but will probably upgrade sooner.
I am at work now (using Tiger as well) and notice the line here, too. I guess I just didn't notice it on the iBook until I had the little issue with the display brightness.
The line really doesn't make the bar look 3D, just sort of dirty. Oh well.
Thanks so much for the reassurance!!

For clarification: udev is in the mkinitcpio.
I'm not sure whether I yet have a good intuition for how you have your machine set up, but I suspect you need to include a cryptdevice flag to the kernel in your grub config. The file isn't found because the kernel doesn't know your root directory needs decrypting first.
My setup is an LVM over LUKS over LVM sandwich. To boot into my system, the grub.cfg contains the line:
linux /vmlinuz-linux root=/dev/mapper/cryptvg-root cryptdevice=/dev/mapper/vg-crypt:root rootfstype=ext4 pcie_aspm=force acpi_osi=Linux acpi_backlight=vendor i915.i915_enable_rc6=1 i915.i915_enable_fbc=1 i915.lvds_downclock=1 ro
Now, most of those flags don't have anything to do with your problem, but note the cryptdevice. It tells the kernel it's dealing with an encrypted filesystem sitting in a logical volume called crypt on a volume group called vg. The bit after the colon tells the kernel to associate this encrypted filesystem with /dev/mapper/root.
As for how to fix your system, I'm afraid I still feel a bit fuzzy about how your LVM and encrypted layers relate to each other, whether you have LVM over LUKS, or LUKS over LVM, or something else. Was there a particular how-to that you followed?

Dark vertical line on iPad mini screen

Has anyone had a dark shaded line running vertically on iPad mini?

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. It could take well over an hour! Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow the on-screen directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
At the end of the basic Restore, you will be asked if you wish to sync the iPad/iPod. As before, say "yes." Note that that sync selection will disappear and the Restore will end if you do not respond within a reasonable time. If that happens, only the apps that are part of the IOS will appear on your device. Corrective action is simple - choose manual "Sync" from the bottom right of iTunes.
If you're unable to do the Restore, go into Recovery Mode per the instructions here. Also, if you have IOS-7, read this.

IMac boots to bit-mapped rows of diaganol lines across screen & then freeze

Im not sure where to post this. Unsure if it's a start-up or a display problem - or both ...
A friend of mine was trying to install boot camp on her 17" Early 2006 but the installation failed half-way through ...
Now, when the machine is switched back on - serious square or bit-mapped looking rows of diagonal lines appear from top to bottom on the screen at 30mm gaps ... it boots up OK to the grey Apple Screen with the spinning cog below - then the lines disappear and the blue start-up screen - looks like it's about to show the 'Starting Mac OS X' window - but then stops - and the cursor changes to a weird rectangular mess - and nothing else happens ... the cursor still moves - so I know the system is not completely frozen - it just won't boot past the blue screen ...
The only way I can get it to boot to the desktop is in Safe Mode (shift key at start-up) - but it boots all the way with the diagonal lines.
Here's what I have tried so far ...
* - reset pram
* - targeted it to another intel mac and used Disk Utility to zero the hard disk to a single Mac OS Extended (journaled) partition (erasing the previous XP portion created by the botched Boot Camp assistant).
* - a clean install of Mac OS X.4.6 via a 'C' boot.
* - restarted into safe mode holding the 'shift' key to get to the desktop.
* - run software update to see if there were any new EFI or Firmware updates.
all to no avail ...
I have also scanned the Apple downloads pages and here in the discussions.
And also the Boot Camp discussions - I can find only one other post with a similar issue - but there is no 'fix' or solution posted ...
My hunch is the firmware has been affected by the boot camp installer - or something to do with the EFI parameters on the video board.
I have tried everything Apple suggests - including an attempt to reinstall the firmware via a hard press of the power button and inserting a special install firmware install CD from Apple downloads - but I can't get the firmware bar to load at start up ...
If I try reinstalling the latest firmware update - I get a message saying "Your Firmware is up to date' - or 'This update is not needed on this machine' ...
Q: Is there a stand-alone installer that will reinstall the firmware - without doing a version check - and just do a fresh firmware install ... ?
Does anyone know a way around the version check.
I am convinced this issue is a software/firmware related problem - I sense the EFI settings have screwed up the video settings on the board - and I all i want to do is refresh them.
It's still under it's initial 1 year warranty - but I'm not sure a botched Boot Camp install is covered ...
Sorry for the long post - but I'm hoping a nice apple guru can help me out with this 'very hairy' problem ..
... macfinger - auckland city
17" intel imac early 2006 1.8GHZ 512RM

OK - here's the result of the rows of diagonal lines across the screen on the 17" Intel Core Duo iMac, which I posted last week ...
The logic board was definitely faulty - it could not be repaired by firmware or otherwise ... the service centre was very vague about which area or part of the board failed - but I suspect it was the embedded video board or VRAM ...
(actually - I still reckon it was a botched firmware - but seeing as Apple's 'Open Firmware' is nor strictly 'Closed Firmware' .... there was no way of actually testing that theory for sure ...
From what my friend has told me - she said this fault was the result of a botched Boot Camp XP installation when loading the Windows drivers from the Mac generated Drivers Install CD which froze - and then trying to boot back into Mac OS X by doing a hard restart, after it failed ...
A message to any future readers of this post:
If your machine shows signs of of the above symptoms - you'll have to return it to an Authorised Apple Service Centre to have the logic board replaced (hopefully under warranty) ...
BE SURE AND BACK UP ALL OF YOUR PERSONAL USER DATA FIRST - AS THERE WILL BE NO GUARANTEE YOUR USER FOLDER WILL BE RETAINED WHEN YOU GET YOUR MACHINE BACK ...
You can still access your HD by doing a safe boot: hold the 'Apple' & 'S' keys immediately after you hear the start-up 'chimes' ....
Once you're back to your desktop - use your machines internal CD-RW/DVD to copy your files to disk ... it's a bit tricky with all the lines across the screen - but persevere - 'cause that's what we did - and we know it can be done.
Good luck ...

Vsync Screen Tearing / Scan Line Issue?

This is something I noticed on my iMac after updating to Mac OS X 10.6 Snow Leopard. I noticed a horizontal break in the screen when I was doing any kind of graphic intensive operation. Anything from scrolling up and down on a web page in Safari, to switching screens in Spaces, to bring up my Dashboard or switching users with FUS. By opening a new movie recording in Quicktime X and simply moving the video around, you can clearly see this break is not a random screen tear, but actually some sort of scan line moving from top to bottom in my monitor. I've never seen this prior to Snow Leopard, but I suppose it is possible this is a hardware issue, rather than a software or driver issue. Can anyone else duplicate this on Snow Leopard? I am on a 2007 2.8 Core 2 Extreme iMac with RadeonHD2600 graphics.
I made a video of the issue and posted to youtube if you want to see what I am talking about.

I also get this issue in Snow Leopard when connecting my iMac up to a TV via the apply video adaptor. I didn't get this with Leopard and I don't get this on my iMac display.
I've been through all the video settings I can find (frame rates, display sizes, etc) and each one still has the issue. SL has changed the system preferences for external video so I guess something else may have also changed.

Vertical blue scanning line won t quit

Vertical blue line continues to float across screen, does not stop! If scanning, I assume for security, one would think that once, twice and then go off?!
But no..it keeps going...no matter what.
It seems to hinder some sites!
Netflix it goes on continually across the movie! Keeps clicking on no matter what I do?!

You could have a hardware problem and you will not be able to fix a hardware problem. You may need to take it to an Apple Store and let an Apple Genius take a look at it. In the meantime, try resetting the iPad and see if that makes the line disappear.
Reset the iPad by holding down on the sleep and home buttons at the same time for about 10-15 seconds until the Apple Logo appears - ignore the red slider if it appears on the screen - let go of the buttons. Let the iPad start up.

Issues with lines across the screen, as well as freezing

Issues with lines across the screen, as well as freezing
Hello all
Got an iMac since January 2008 and I do like it a lot, even though it has some issues:
-- It displays (quite often) lines partially across the screen
-- Lines appear as well when opening applications or when menus come up
-- The system freezes more than I like to admit (more than my Windows/Ubuntu box)
I don't know if the freezing has to do with the lines that are shown on my screen. But I assume that both issues relate to some video card problem. I can't be sure - but that's what I assume from living with this issue day to day.
The line on the desktop (most of the time it is there before login) I can always get rid of by changing the display resolution to something else and then changing it back. Normally the line is gone, or, reappears on a different spot on the desktop. But repeating the procedure removes the line.
However, this does not mean that the lines are not showing up again when launching apps or displaying menus!
And since those lines appear to happen randomly, I think it's safe to assume that we're not talking dead pixels here, either...
About the freezing:
My iMac freezes sometimes when I move the mouse around, when switching desktops using "spaces" or when the zoom function of the Dock kicks in. Sometimes the screen goes completely black, sometimes completely white. The mouse, however, always works. But the system requires a reboot.
Again, this happens too often to feel comfy about it.
With my little knowledge of Mac troubleshooting I assume that there's something wrong with the ATI card that's built into my Mac. On the other hand, some people say that they started getting similar issues after updating their OS to Leopard. Again other people say that such issues stem from an ATI revision that is too old and the Mac should get a new ATI card. And how would that work? Isn't that an "all-in-one" machine with everything soldered onto the mainboard?
So, any help in this matter is greatly appreciated...
Cheers,
Rainer

Here are a few screen photos I've taken (not screenshots, as the lines are not visible when taking screenshots. I used my digicam to snap those...).

IPhone 4s scan lines and other issues?

So I recently bought an iphone off of craigslist in June (Biggest mistake I've ever made). I met up with the person and the iphone looked pretty fine to me, who's never had an iphone btw, but as soon as I got home I noticed slight lines going across the screen. They were red and blue. They bothered me, but not too much. It effected the back camera more than the front but I said hey I can live with it considering I got the phone really cheap. Well now it's been 3 months since and it's gotten much worse. The scan lines are worse, the screen freezes, then fades to black. Also when I try to use the camera everything goes green and distorted then turna inverted. And when I try to look at pictures they have vertical lines thru them so I cant even make out what it is. If I really want to see a picture I have to screen shot it to get a quick glimpse. Also I noticed the screen freaks out more when there is color. So say I'm on my screen lock and my screen lock is just white, then the horizontal lines arent too bad. But if I go to my home page were all the apps have color, it freaks out. Or when I go on instagram, it completely wigs out and the screen freezes and fades out. I haven't dropped it accept once off the table and cracked the back, but I had this problem before so I know that's not why. I don't know if it has any water damage from the previous owner. The only thing she mentioned was that the screen was cracked. Please if you know what's wrong or have any advice please let me know. Thank you.

The screen needs to be replaced.
You can see if the phone have been in contact with water by looking at the indicators. You'll find dem here: http://km.support.apple.com/library/APPLE/APPLECARE_ALLGEOS/HT3302/HT3302-iphone _4-activated-001-mul.png
If they turn out to be read that indicates that the phone is water damaged.
You should talk to folks at apple to here what they can do to help you out.
Good lock!

Horizontal red lines across video after rendering

Hi I was color correcting a video in Adobe Premiere Pro Cs5 and had remove some noise with Neat Video. The video looks fine with the small screen, however, I adjusted it to full screen and noticed a lot of red horizontal lines across the whole video. The video was 720x480. I would like to know what am I doing wrong. I'm a beginner in color correction and using Adobe Premiere Pro. Thanks.

i hope the picture helps you. There's not much information to get. It only happens after I finish rendering. I'm using adobe cs4 premiere. There is nothing wrong with the footage.

Strange flickering lines across screen, opening Photobooth makes them go away?

Hi everyone,
I've been having a very strange problem with my 2011 Macbook Pro 15" for quite a long time now. It's basically flickering lines across the screen, and the screen 'folds' in on itself, squashing the display vertically and stacking them on top of each other. Sometimes it's terrible, sometimes it's bearable. Sometimes the screen goes completely black. It's super weird. Here's a photo I took my phone, as I screenshotting shows nothing out of the ordinary:
The really really weird thing is that when I open Photobooth, as in the apple webcam program, the problem completely goes away (until I quit it). I had hoped this was a software issue, so I backed up and formatted my hard drive and then installed a fresh copy of OS X - and the exact same thing happens! I barely made it through the system setup!
I beg, someone help me!

Please read this whole message before doing anything.
This procedure is a diagnostic test. It won’t solve your problem. Don’t be disappointed when you find that nothing has changed after you complete it.
Third-party system modifications are a common cause of usability problems. By a “system modification,” I mean software that affects the operation of other software — potentially for the worse. The following procedure will help identify which such modifications you've installed. Don’t be alarmed by the complexity of these instructions — they’re easy to carry out and won’t change anything on your Mac.
These steps are to be taken while booted in “normal” mode, not in safe mode. If you’re now running in safe mode, reboot as usual before continuing.
Below are instructions to enter some UNIX shell commands. The commands are harmless, but they must be entered exactly as given in order to work. If you have doubts about the safety of the procedure suggested here, search this site for other discussions in which it’s been followed without any report of ill effects.
Some of the commands will line-wrap or scroll in your browser, but each one is really just a single line, all of which must be selected. You can accomplish this easily by triple-clicking anywhere in the line. The whole line will highlight, and you can then copy it. The headings “Step 1” and so on are not part of the commands.
Note: If you have more than one user account, Step 2 must be taken as an administrator. Ordinarily that would be the user created automatically when you booted the system for the first time. The other steps should be taken as the user who has the problem, if different. Most personal Macs have only one user, and in that case this paragraph doesn’t apply.
Launch the Terminal application in any of the following ways:

☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
When you launch Terminal, a text window will open with a line already in it, ending either in a dollar sign (“$”) or a percent sign (“%”). If you get the percent sign, enter “sh” and press return. You should then get a new line ending in a dollar sign.
Step 1
Triple-click the line of text below to select it:
kextstat -kl | awk '!/com\.apple/{printf "%s %s\n", $6, $7}' | open -f -a TextEdit
Copy the selected text to the Clipboard by pressing the key combination command-C. Then click anywhere in the Terminal window and paste (command-V). A TextEdit window will open. Post the contents of that window, if any — the text, please, not a screenshot. You can then close the TextEdit window. The title of the window doesn't matter, and you don't need to post that. No typing is involved in this step.
Step 2
Repeat with this line:
{ sudo launchctl list | sed 1d | awk '!/0x|com\.(apple|openssh|vix)|org\.(amav|apac|cups|isc|ntp|postf|x)/{print $3}'; sudo defaults read com.apple.loginwindow LoginHook; } | open -f -a TextEdit
This time you'll be prompted for your login password, which you do have to type. Nothing will be displayed when you type it. Type it carefully and then press return. You may get a one-time warning to be careful. Heed that warning, but don't post it. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
Note: If you don’t have a login password, you’ll need to set one before taking this step. If that’s not possible, skip to the next step.
Step 3
launchctl list | sed 1d | awk '!/0x|com\.apple|org\.(x|openbsd)/{print $3}' | open -f -a TextEdit
Step 4
ls -1A /e*/mach* {,/}L*/{Ad,Compon,Ex,Fram,In,Keyb,La,Mail/Bu,P*P,Priv,Qu,Scripti,Servi,Spo,Sta}* L*/Fonts 2> /dev/null | open -f -a TextEdit
Important: If you formerly synchronized with a MobileMe account, your me.com email address may appear in the output of the above command. If so, anonymize it before posting.
Step 5
osascript -e 'tell application "System Events" to get name of every login item' | open -f -a TextEdit
Remember, steps 1-5 are all copy-and-paste — no typing, except your password. Also remember to post the output.
You can then quit Terminal.

What would cause a slim horizontal line across the screen of my iMac?

There is a slim line across the Center if the screen. It is horizontal. It does not appear every time I boot up, but it is causing concern.

Welcome to Apple Support Communities
It would mean that your display or GPU are starting to fail, most likely the GPU, as the line is not permanent. Does the line move during the time your iMac is turned on or change if you start up in safe mode (holding the Shift key while your Mac is starting)?
A good test you can do is to make a screenshot of the screen when your iMac is showing the line. To make the screenshot, press Command, Shift and 3 keys, and the screenshot will appear in the desktop. Double-click it and see if the line appears. If it appears, it's the GPU. If not, it's the display
