Desired effect: narrow line across map with a moving spot
Here's what I'd like to do. I want to show a journey on a map by having a bright little spot moving along the road. I drew a black line along the road on a clear transparent sheet on top of the map, scanned it, and then used the video filter >channel>invert to make this line white on a black background. So, I have the route (a curving line matching the roadway) on a separate clip on V2 above the map on V1. The scales and alignment are not a problem. I have tried applying the alpha and luma travel mattes to make the black transparent (to show the background map). Also, I want to leave the white line transparent and use the moving highlight effect that I have successfully learnt from pages 295ff of Tom's manual.
I imagine that I would need two travel mattes, one alpha and the other luma, but I'm not having any success with the layering in the video tracks.
Could anyone suggest the next steps I should take please? I'd appreciate any suggestions if anyone has achieved this effect before. Thank you. Keith
Hi -
In a bit of a rush but here is some help -
Place the full Map BG on V1.
Place the white line you made on V2.
Place a solid color from the Generator Button > Matte > Color on V3. Double click on the clip on V3 and set the controls to white or whatever color you want you line to be.
Now Control click on the clip on V3 and from the drop down menu choose Composite Mode > Travel Matte Luma, and as soon as you click that you should see your line appear without background over the map on V1.
To animate the map, keyframe the crop controls on V2 to have the line grow in the direction of travel.
Once you get that set, get a soft oval from Generator Button > Shapes > Oval and edit that to V4. Double click on it and set the size, softness, and color you want your leading "spot" to be. Don't worry about position right now. The bigger you make it, the easier it will be to track the line below. Once you get the approx. size, softness, color, then control click on the clip of the oval on V4 and from the drop down menu choose Composite Mode > Add.
Now you should have a soft glowing oval.
Next at position keyframes that track the line movement that is being shown on V3 but caused by the crop keyframes on V2.
Hope this helps.

Hello there, can someone help me please. I erased all data and settings last night and now my IPAD just shows a line across it with the apple logo. It is not responding to the on / off switch. I have connected the IPAD to my laptop so i can reinitilise it but nothing is happening - it doesn't appear as a device on my laptop (the USB port is working OK) Has anyone else experienced this and how did you overcome it? Thanks
thanks for the reply gdgmacguy! but is there any way to stop it? i was thinking of just manually uninstalling apps and deleting contacts. i cant wait any longer, lol.

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 512RMOK - 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 ... -
Start Up Screen Freeze With Lines Across Screen
The computer is the iSight version. In moving it from one room to another I shut it down properly. I had a back-up HD with Time Machine which I shut down properly. When I tried to restart it shortly after at the new location, the start up chime sounded and the Apple logo came on with the spinning wheel but the screen had light blue horizontal lines across it. The lines at first seemed squiggly but after restarting a few times, the screen seemed to be divided into vertical columns about 3/4" wide with one column having pixels colored light blue and the next column having the same coloration but the row of colored pixels was above the previous one. This arrangement alternated across the screen. I hope this is clear. After a while the spinning wheel and the screen froze and the computer would not continue with the start up.
I reset the SMU by unplugging the power cord, etc. but this did not work. I tried restarting in safe mode-negative. I tried restarting from the original disc-negative. Initially, it sounded like the disc was working because it makes a distinctive noise when a disc is working in the drive but eventually the same initial screen came on with the wheel spinning and then freezing. I tried the current versions of Techtool Pro and Disc Warrior and neither worked. The same thing happened. The noise from the disc drive but the same screen would come on and then the spinning wheel would freeze. Initially the screen with the Apple and the spinning wheel and the lines came on quickly but after a number of times turning the computer on and off, the screen remained dark with a faint light and when the screen came up, the spinning wheel was already frozen.
I use a flight simulator-X-Plane- a lot and some times when I leave it on, screen saver comes on and when I bring the screen back up, the first screen that came up and quickly changed had to do with X-Plane but not with what I was doing. Also, sometimes when I left it and came back there was a different screen but still part of X-Plane but not the screen I left before. I don't know if this is related to my problem or specific with X-Plane. I brought it up because this is the only thing that was different prior to this problem but may not be related. Right now, I've turned it off(obviously) and disconnected the power cord and the keyboard.
Any help would be appreciated.I've started taking the iSight apart. Detaching the plastic took some time and care but with only a few tears. Separated the screen. The main board is positioned such that the capacitors are on the bottom. So many connections and most of them small. Have to be careful. So many small screws. I hope I can remember where they all go when I put everything together-I hope. I'm at the point where I've turned the main board over so that the capacitors are showing. I hope I can reconnect correctly. Two capacitors have a slight bulge at the top compared to the others. Although I am not sure whether these two are part of the problem. There is another one that has no bulge but there seems to be some stuff on the top. It is not corrosion so I'm not sure whether it was manufactured that way or something is wrong with it. I finally found the battery. Just to change it is such a job. You have to disconnect a lot of stuff and turn the board over to get at it unless Apple technicians have a shortcut. Do you think the battery could cause the problems I have? Anyway, if I have the board exposed already might as well try and change the capacitors. I have not come across any video that shows how to expose the underbelly of the main board. Nor have I seen any video that shows what each part is. On the left side of the layout is an long rectangular shape covered over with black plastic. I haven't checked it out but I assume it is the power source. At the upper left there is a rectangular board with capacitors underneath but there are connections underneath that are so tightly stuffed that I couldn't turn it over but I could lift it up a little and see the heads of some capacitors and there wasn't any bulging capacitors or corrosion. There's one big capacitors under there. Much bigger then those on the mother board. Interesting observation. When I turned the screen over to expose its back most of it was frosted except for a small rectangular piece that was dark but glassy like and the glass like part lies exactly on the small rectangular board about 4X5 or 4X6. Interesting why this small section of the back of the screen should be different from the rest of the back and why it should be exactly above the smaller board. Like the previous versions of iMac, it would be so easy to be able to open the back and have all of the capacitors exposed. My next action is to contact one of the references you posted and see if I can get these three capacitors and the battery from Radio Shack or somewhere and solder the capacitors to the mother board. After all of this putting the whole thing together correctly without ending up with extra parts. One thing did break. Next to the fan in the middle there is a piece of metal attached to the back. There is a small narrow slot in this metal that another piece of bent metal seems to go into and was soldered to it and when everything is put together it seems, although I'm not sure, that this metal touches the back of the screen. It looks like I have to solder it back. I don't know what its purpose is, maybe it grounds the screen? I thought the piece of metal was something to pull in order to liftup something else. So far that is the only thing that has broken and hopefully can be easily fixed. But nothing that seems easy is easy.

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,
RainerHere 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...).
Here's the link to those screen photos displaying some of the many lines I keep having:

Needless to say, as I typed this message here, I had a nice line going across my Safari window..

White screen with battery with red line across- software issue
My phone froze last week when I plugged it in for the night. The battery had been dying pretty quickly for the 2 weeks before that. So i took out the battery and put it back in and then this white screen appeared with a battery and a red line across. I replaced the battery and it still gives me the same message. I tried pluggin the fone into the computer and reloading the software from the blackberry site and still nothing. The computer is not even registering that the fone is plugged in. Help please! I am running out of ideas!

Suddenly I can't move files to trash, whe I try to drag them to it there is a cirle with a diagonal line across. HELP!
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.
Triple-click the following line on this page to select it. Copy the selected text to the Clipboard (command-C):
{ sudo chflags -R nouchg,nouappnd ~ $TMPDIR.. ; sudo chown -R $UID:staff ~ $_ ; sudo chmod -R u+rwX ~ $_ ; chmod -R -N ~ $_ ; } 2> /dev/null
Launch the Terminal application in any of the following ways:
☞ Enter the first few letters of its name into a Spotlight search. Select it in the results (it should be at the top.)
☞ In the Finder, select Go ▹ Utilities from the menu bar, or press the key combination shift-command-U. The application is in the folder that opens.
☞ Open LaunchPad. Click Utilities, then Terminal in the icon grid.
Paste into the Terminal window (command-V). You'll be prompted for your login password. Nothing will be displayed when you type it. You may get a one-time warning to be careful. If you don’t have a login password, you’ll need to set one before you can run the command. If you see a message that your username "is not in the sudoers file," then you're not logged in as an administrator.
The command will take a noticeable amount of time to run. Wait for a new line ending in a dollar sign (“$”) to appear, then quit Terminal.
Step 2 (optional)
Take this step only if you have trouble with Step 1 or if it doesn't solve the problem.
Boot into Recovery. When the OS X Utilities screen appears, select
Utilities ▹ Terminal
from the menu bar. A Terminal window will open.
In the Terminal window, type this:
res
Press the tab key. The partial command you typed will automatically be completed to this:
resetpassword
Press return. A Reset Password window will open. You’re not going to reset a password.
Select your boot volume ("Macintosh HD," unless you gave it a different name) if not already selected.
Select your username from the menu labeled Select the user account if not already selected.
Under Reset Home Directory Permissions and ACLs, click the Reset button.
Select
▹ Restart
from the menu bar. -
My 1st generation Ipod touch won't turn on at all and whenever I press the buttons to reset it all I get is a white screen, or a white screen with black lines across.Help pleaseeeeee!
You can work through the five 5 R's of troubleshooting to rule out the possibility of corrupted software.
http://www.apple.com/support/ipod/five_rs/
It might also be a good idea to let the iPod's battery fully drain. Then charge it back up and restore it once more in iTunes.
Otherwise, it's likely a hardware issue with the iPod's LCD display, meaning you'll need to take or send your iPod in for service either via Apple or a third party repair service. Here is Apple's repair pricing.
http://www.apple.com/support/ipod/service/prices/
Note that they don't actually repair the device, but exchange it for one of the same generation, model, and capacity. A third party service will actually replace the damaged part for a little less. Google "iPod screen repair" and you should get a number of results to work with.

Ipad with yellow line across screen
I received my 32GB WiFi four days ago. By the second day, a yellow line across the screen appeared and still remains in the same place. It's located about 3 inches from the bottom and it does not disappear or move when the screen is on landscape mode.
I have read about Ipads with yellow screens but none with a single yellow line.
Can somebody help me ?
JFI had the same issue show up last night. I took the iPad into the Apple Store today, and they swapped it out for a new one; no problem, no hassle.

I am having problems with video and high content webpages freezing. I am also getting pixel lines across my webpages. Maybe two or three lines. I was running os 10.4 but I just up graded to 10.6 the other day. I have 2GB of RAM.
Exactlly which model iMac do you have?
see > How to identify iMac models
Unfortunately that is not all that uncommon for the Early Intel iMac's given there age and the fact that the air intakes are probably choked with dust. Then add the extra heat caused by running a more intense OS X which is causing it to run a little warmer than normal and putting extra stress on the graphic and display components.
My 6½ year old 17" Early 2006 Core Duo w/2GB of RAM is also running 10.6.8 and is also starting to get a single line that (knock on wood) goes away after a few minutes, while many others started getting permanent ones after 2 or 3 years. One thing that I think has helped, is that about every 3 or 4 months I shutdown and vigorously vacuum out the bottom grill work and small vent under the stand to keep it running cool.
On that note: unfortunately I can only suggest that you clean your intake vents and hope that no permanent or irreversible damage has been done. -
The ipod will show flashing white lines across the screen, going down, it then does somthing where the screen will dim down but its not like when the backlight goes on and its about to lock. It dims the background of your ipod and the icons and letters kind of all look defined. Then the ipod gets all pixelized and it has big boxes on pixels and its all differnt colors like purples and greens, red, etc. then it turns right off and restarts itself less than 5 seconds later. These things happen really fast but when it does it's really weird. It first happened 3 times in a row, Its still continuing to happen but i can manually turn off my ipod by holding the lock button down and not even 30 seconds later it's like its possessed and it turns on by itself. I talked to somone on appel and they told me to back it up and restore it. I restored it and as soon as the process ended and tuirned on like a brand new ipod and like clockwork the glitch happened instantly. It did it a couple of times throughout the night and i kept having to watch it so i can keep turning it off manually because it continues to turn on by itself. I talked to 3 different people on Apple Support and they couldnt even find an answer for me. It's so weird.
Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode
How to put iPod touch / iPhone into DFU mode « Karthik's scribblings
- If not successful and you can't fully turn the iOS device fully off, let the battery fully drain. After charging for an least an hour try the above again.
- Try another cable
- Try on another computer
- If still not successful that usually indicates a hardware problem and an appointment at the Genius Bar of an Apple store is in order.

Also,
If you restored to factory settings/new iPod via iTunes (Not via Settings>General>Reset>Erase all Content and Setting) and still have the problem that indicates a hardware problem.
Make an appointment at the Genius Bar of an Apple store..

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:
☞ 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.
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. -

Why are you both manually mapping trigger lines using viMapTrigger AND automatically configuring the crosspoint switches using niTClk_ConfigureForHomogeneousTriggers? When you use viMapTrigger you are reserving the trigger lines. This may be why you receive the error. I am assuming niTClk_ConfigureForHomogeneousTriggers is all you want to do.
If you desire to manually map the trigger lines, please follow the instructions in the attached pdf. These instructions are also documented in the NI-TClk Synchronization Help.
Please let me know if you have further questions or if this does not resolve your issue!
