Distorted video problem

I have a problem on a rig I built for a m8,
the video at startup is fine but after a short time the screen becomes more and more distorted (in Word or Games) until it is totally unusable.
The hardware is:
K7N2 Delta2 with Athlon XP 3000
FX5200 128Mb AGP
1Gb PC3200
17" LG TFT (analog)
Anyone have any ideas ?

Hello !!
Does your GF5200FX have its own Power Connector ? Is it inserted correctly ?
Are you using the power cable you plugged in VGA Card for other devices also ?
Give the FX5200 its own Power cable and do not put other devices on this cable.
Which amps are given on each voltage rail by your PSU ?

Distorted video after export

Hello.
I have exported a video using AVCHD mp4 format. 25 fps. 1280x720 px. Aspect "Square Pixels(1.0) 1:1. Both tried CBR and VBR. With target bitrate 1.6 Mbps. See the attached pic for settings. And also see the distorted video problem I have. Can you please help me with correcting the export settings? Thanks.

The image of the lady shows interlace artifacting and that doesn't make sense since the export was progressive and that should deinterlace the footage. One thing to check, I see that Aspect Ratio is set to "Custom", this ought to be 16:9 so please try that. Also just noticed "TV Standard" is set to "NTSC", should be "PAL" for 25fps video.
Perhaps you should take a step back. What is the intended delivery format? There are a ton of H.264 presets and most of them willl yield good results. You have everything customized and that is likely the issue. I would start with a decent preset and see what that does before you change things around.
Thanks

24" iMac Video Problem on Window XP

I brought 2 units of 24” iMac last month and using boot camp to install windows xp. Both iMac are completed the installation of window xp and one of the iMac run normally but video problem found on second iMac. After running in window xp about 5 – 10 mins, the screen images distort suddenly. If computer restart again, the display will become normal for 5-10 mins and distort again. But the second computer runs normally in Mac OS. Please kindly help….

Are the driver installed, or installed properly?

Distorted video - too wide

I have posted about this on Crackberry.com. But maybe should bring it up here.
The main problem is that when viewing a video on my Z10, images are stretched left to right and so people are wider than normal and also objects like buildings, etc also are too wide. It is less noticeable in landscape screens. Upon a suggestion I received today, I opened the same video in the Z10's Browser and the video is NOT distorted. But I think that the app should work properly.
Here's some extracts from the thread:
http://forums.crackberry.com/blackberry-z10-f254/distorted-video-too-wide-849144/
I copied a homemade mp4 file to the z10 of one of my vacation trips (I create a dvd movie from the digital photos). The image is "widened" and frankly I don't need any help in the WIDENING area. It seems to show correctly on my PB and on my computer. But on the Z10 it is wide. Pinch does not HOLD - bounces right back to wide.
There does not seem to be a setting to alter this behavior or appearance. If not connected to the tv, the DISPLAY/hdmi setting is grayed out.
I just created a new video. Since the phone was going downstairs, I copied the mp4 video to the phone. Plugged it into my tv but, once again, the images are distorted - too wide. So the screen is spread left to right and people are too wide. The effect is less noticeable on Scenery but you can see it for buildings and such. And, it is not just on my TV but it is also evident on the Z10, itself. So, the z10 appears to not be displaying the image or video WIDTH correctly.
I then copied the same video to my Playbook (another BB device) and the video is fine and NOT DISTORTED.
I am still on the original Verizon bb10.1.xxxxxxxxxxxx OS.
Any idea if there is a setting on the phone that I am missing.
**bleep**! I had not thought about opening the video in the Browser. You are RIGHT - the video proportions are correct when opened in the Browser. So this is a definite bug in the Video app's software or settings. Of course, one should not have to go into the browser to view videos because the app is BROKEN.
I wonder if Kalemsoft or other video apps performs correctly?
When I first posted the thread, I did not know if it was my desktop software's coding or resolution or .... So I burned off the video in format after format to no avail. I am somewhat surprised that no one else has raised this issue. Maybe I will take it to the official bb forum.

Video Problems with 7.0.1

Just as with iTunes 7 I am having video problems galore. I can play all the music videos and TV shows that I currently have in my iTunes library via QuickTime. However, if I attempt to go and browse either music videos or TV shows, iTunes comes to a dead halt and I cannot even close the iTunes program without utilizing ALT, CTRL, DEL. My computer is "authorized" as I have no problem browsing in music, but if I do get as far as the TV Show home page, I get a message saying that I "CANNOT BROWSE ALBUM COVERS ON THIS COMPUTER." I am really at a loss as to what else to try and would apprecaite any assistance offered. Thanks all.

b noir, here are all the symptoms that I am currently experiencing with 7.0.1:
1. iTunes takes 3-5 minutes to boot-up and will ONLY start if an iPod is attached. Manual opening will not work.
2. Any time that I click on the "TV Shows, Music Video, or Movie" areas of iTunes Music Store the entire iTunes program freezes. I can only exit iTunes at that point by "ALT, CTRL, DEL."
3. When I do attempt to enter the TV Show area, I do eventually get a gray and white sign where the TV Show icons should be and the message says "Unauthorized to browse album covers on this computer." At this point the program is frozen. I should mention that the computer is authorized and I have NO problem browsing, playing, or purchasing music in the iTunes Music Store.
4. I have no problem whatsoever playing the music videos and TV Shows that are already a part of my iTunes Library. No issues with QuickTime's playback whatsoever.
5. There is absolutely no problem with the purchasing, playing, or control of my music portion of iTunes. I have no distortions at all and did not have them with 7.0.
6. Many times after updatingmy iPod with new music, changes, or playlists, the window of the iTunes player will say that the update is complete but does not mention anything about the iPod being OK to disconnect. Several times I tried to manually disengage by clicking the release next to the iPod in the source column, only to get a message telling me that iPods files are currently in use. Eventually I can make the disconnect.
7. In general the amount of time that it takes to sync my iPod to iTunes is at least triple what it was with iTunes version 6.
Whew. That's everything. What say ye?

IMac G5 Distorted Video (Possibly Capacitors)

This is the main story you can skip this if you want to get straight to the problem: Hi, I got an iMac G5 (1st Generation 17-inch 1.6ghz PowerPC no isight) from my dad's friend and he said I could look around inside. He said he already looked around and switched around the ram etc. So I booted it myself and got a blue screen, did a PRAM reset and rebooted it about 10 times. I got the distorted video to look OK. (I am using some third party power cable, and a windows keyboard and mouse.) So then I held down my "option" key (Alt) and booted from a tiger cd. I was able to install it, but when I boot I can only boot from safe mode. I still get distorted video but you can still kind of see what is on the screen. If I don't boot from safe mode I either get a kernel panic when booting or when loading OSX, or I get a blue blue screen. If I try to put it asleep it crashes and if I leave it alone for just a little while it crashes. I tried an SMC reset, didn't work. I did command option o f and reset everything, didn't work. Also OSX wont detect the built in speaker, bluetooth, or headphone jack. The fans also randomly go FULL THROTTLE if it froze or if there was a kernel panic END OF MAIN STORY
I looked into to this a little bit more and found out it is MOST likely to be the capicitors so I was like huh. So I unscrewed the 3 bottom screws popped open the back and then THERE IT WAS! 2 blown capacitors. They were leaking the electrolyte fluid or whatever. I this picture I found of my same model with the blown capicitors, I circled the two blown capacitors I found. (this is not my picture) http://i.imgur.com/aFArv.jpg and so yea, I ordered two of the ones 1800hu or nu idk 6.3 V on Amazon. My dad's friend (the same guy who gave me this) has a soldering iron and will solder them in. I just wanted to see if this COULD be the problems or some of the problems could be related to other things. Thanks.

That is highly likely to be your problem. They recommend replacing ALL the capacitors while you're doing it. You have to disassemble the entire iMac while doing the soldering (from what I've read, I've never undertaken the job myself), and you can buy kits for under $20 (google G5 capacitor kits). I think they also recommend reapplying the thermal paste to the processor.
It will probably need a new PRAM battery while you've got it open.
Of course there is no guarantee that the RAM and Hard Drive are okay, but they probably are.
Good luck.

Distorted video after importing to iMovie 09

Please HELP!
After converting a video into .mp4 format (that i can edit it in iMovie 09) and importing it to iMovie 09 I get completely distorted video; the picture is squeezed & the sound is not synchronized.
Before i made a lot of similar videos & everything was ok.
When I try to use precision editor, it doesn't help that much, i still see bad syncr. of sound and bad picture.
Please help me, cause the video is great & i need to edit it.
Am i using the wrong importing or converting format?
If so, which do you recommend instead?
The one I always use is: APPLE TV MPEG-4 720x432 (*.mp4)
These are the properties of the converted video:
Video ID: 0x2
Format: xvid
Resolution: 720x432
Frame rate: 30.00 fps
Bit Rate: 1501 kbps
Total length: 00:25:15
Audio ID: 0x1
Format: AAC
Sample rate: 48000 Hz
Channels: 2
Bit rate: 127 kbps
Is there perhaps just a simple trick that I can use so that it automatically fixes this problem?
Any answer is welcome!!!
Please be fast with the answer!!!

Macbook Pro Video problems stemming from logic board

Recently my MacBook Pro 15" 2.4 GHZ started acting odd. Doing normal (i.e. nothing too CPU/Video card taxing) the monitor would work fine But it almost always happens immediately when playing a game, WoW for example. Then the display would show random odd characters and colors, almost as if the laptop went into a fit of rage. This almost never happens when surfing the web, using a text editor, etc.
I called Apple tech support and scheduled an appointment with a local reseller. The attendant there hooked up a device that quickly said something about a "4v video display adapter" not functioning correctly. She informed me that this meant the logic board was bad. I was quoted something about $310, but since I don't have that much to spend atm I didn't ask her for details.
My only real question at this point is how much does something like this cost to repair/replace? If it is the $310 (before shipping and handling of course) then I'm almost happy. If it turns out to be too much more then I will have to consider relegating my favorite laptop to minor duties and consider buying something else.
Thanks for any info/help with this.

Yesterday my laptop became emotionally distressed...my screen went berserk, diagonal lines everywhere. I rushed to the apple store and met with a genius, unfortunately he was unable to help me...I almost dished out $310 to send it in for service.
After multiple hardware and software diagnostics (Techtool Pro, ASD, Disk utility, Disk warrior, and Drive Genius) I could not find the problem. Then I came to the conclusion that maybe there are new default settings from new Snow Leopard update (10.6.3). MBP’s default fan speed...The GPU was overheating and creating a distorted video signal. How did figure it out you might ask, well I put the laptop in the freezer for 3 min and guess what, the screen went back to normal (Somewhat impatient). Then, I found little app that let's you adjust the fan speed RPM.
*smcFanControl 2.2.2* Control Intel Mac fans to make it run cooler.

Also, I will recommend a widget called iStat Pro and it also has a matching iPhone app to monitor your laptop temperature and other important info from afar.

I am somewhat concerned though, did overheating the GPU cause lasting damage to my logic board?Time will tell. Also, is this a issue that Apple should look into....Yes.

Mini DVI to VGA Adapter Video Problem

This year at Randolph-Macon College we replaced the Math lab Emac computers with IMac G5 Intel machines. The laboratory has an NEC model MT1050 projector with a manufacturer’s date of August 2002. We can not seem to get rid of ever present scan lines. We can slow them down and speed them up by adjusting resolution and refresh rates, but nothing will remove them. We are connecting the IMac to the projector via the Apple Mini-DVI to VGA Adapter. It is specifically designed for use with the iMac (Intel Core Duo), and the adapter connects to the Mini-DVI port of the computer and the VGA end of the adapter to an external VGA monitor or projector.
Troubleshooting the problem we have swapped IMac Intel computers with no luck, but we still have to use the Apple Mini-DVI to VGA Adapter. When we hook the projector to a Intel Mac Book Pro, we have to use a different adapter, but then it works perfectly. In fact, everything we try using other adapters works fine, it’s just when we use the Apple Mini-DVI to VGA Adapter that we experience the video problem.
Has anyone experienced this problem and if so, have you been able to remedy it?
iMac (Intel Core Duo) Mac OS X (10.4.8)

I don't have much to suggest, except to ask if you can try with a different mini-DVI to VGA adapter. (i.e. do you have more than one on hand to make sure yours isn't just defective?) Make sure it is firmly seated into the iMac.
I use the same adapter to provide an extended desktop on an old CRT monitor and the display is great.

T400 - Video problems and a long wait for repair...

Hi,
I'd just like to state my experience with Lenovo Customer Support for a video problem with my T400. Bottom line, as of today, it's been around 27 business days that it's been with Lenovo, and 41 days total since it's failed on me, and nobody, including Lenovo Customer Support, seems to know what its status is exactly, except that they're waiting on a part which has no ETA.
In July 2009, I bought a T400, a 2764CTO version with the switchable graphics between the internal intel graphics and the ATI GPU.
All was well until February 1st, 2010, when the LCD sudden wouldn't work. Well, it would work, but the screen was very very dim, even with the display maxed out on brightness. You would have literally bring your nose to the screen in order to even make out any text or images - definitely unusable. However, if you hooked up an external monitor via the video output, the T400 would display video output properly that way. When I did this, I noticed that the switchable graphics option wasn't there any more - couldn't switch to the ATI GPU. Based on this, I figured it must be a video card or LCD issue, or a combination of both.
So, I called Lenovo Customer Support (CS) at 1-800-565-3344, since I'm up here in Canada, and I initially was issued a case number of 41JRFSD, and I agreed to send it to a local Lenovo Repair Centre. Oops, my bad, I made a mistake using the locator tool I was told to use at bplocator.lenovo.com, and thought the Centre was relatively close. Not quite. So, I called Lenovo CS again, and they issued me with a new case number, 40KWSYF, and said they'd send a box for return to depot. And within 2 days, Feb 2nd or 3rd, I got a Purolator courier return box. That's fast service! Pleased, I put my T400 in according to instructions, and I sent it off.
Fast forward to about mid-February. I called Lenovo CS, and apparently there was a delay - the depot needed a part that wasn't in stock. Fine, I know these things can happen - I'll wait.
Fast forward to March 1st. I talk to a Lenovo CS rep, and it appears that the part needed has arrived, and they've put a rush order to get the computer back to me. Great!
Fast forward to March 8th, still no computer. I talk to another Lenovo CS rep... strange, there's no update. The issue gets escalated to the Depot managers.
Fast forward to March 12th. Still no word on my T400's status. An email fron CS has been sent to the depot. Not even the CS reps know what's going on. The rep I talk to figures there should be a response by the end of the day.
Fast forward to today, March 13th, 4:50pm Pacific Time. I just finish talking to Lenovo CS, there's been no response from the depot. Apparently there's a part that they're waiting on for repairs, but there's no ETA on it. Is it the same part that I've waiting on all this time? Is it a new one? I don't know.
At this point, I've been told to send an email explaining my situation, and I've also been told to talk to Scott the next time I call CS on Monday after 3pm Eastern. I have to stress that the Lenovo Customer Support Reps I've talked to have all been very sympathetic and have been courteous, helpful, and professional - something I appreciate from having worked in Customer Support myself. But the bottom line remains: my computer's not back to me.
So, my questions to the community here: is my experience here typical? Is there any hope of my seeing my computer back, or even at least just the hard drive? I've used Lenovo computers for work for the past 7 years, and it was my good work experiences that led me to buying a Lenovo for home use. However, it's been a while since I've been without my T400, and I was hoping to get my taxes done on the computer too, since they're due at the end of March. I'll reserve judgement on Lenovo until I get my computer back, but at this point, all I can say is... I'm disappointed.
If you're reading this, I'll let you judge my experience for youself. I'll update my case as it progresses.
Thanks!

Hi all,
So, an update with some good news: my computer is finally back!
After a total of over 40 business days (just over 2 months) I finally have my T400 back at home, working again!
According to the spec sheets, the repair depot had to replace: the systemboard/planar, display/LCD panel, LCD cable, PC card, bluetooth, and the inverter. BIOS/Embedded controller was also updated, along with the regular diagnostics to ensure everything was working properly.
I give Lenovo credit though: they got the final parts to repair the computer on Monday, April 5th, and shipped my computer back to me for the next day (today, April 6th). That's fast service, once repaired!
However, my case spans over 4 screens of updates and repair depot orders of parts.
Also, it took me over 10 calls to Lenovo's Customer Service, plus an escalation to a higher-level manager after 1 month had passed, to get progress updates and ETAs for repair.
Lenovo called me only once to give me an update, and that was the manager whom my issue was escalated to: all the other times, I called Lenovo for an update.
The story doesn't end here, however:
In talking to Customer Support, they told me that Sales might be able to sell me an extended warranty at a discount, given the issues I had. And indeed, after talking to Sales, they offered me a 1 year warranty extension at a price of just over $100 CDN, plus tax. This is a sale price, compared to the regular retail of $129. Unfortunately, they can't sell me just one month.
At this point, I refused their offer, and again escalated to a manager to request an extension of exactly 1 month on my existing warranty. I figure 1 month delay in repairs, that's plausible - crap happens, and while most repairs take 5-10 business days, I can understand it can sometimes go higher. Two months though.... My request for a warranty extension is being considered by the manager it was escalated to.
So, one last question for you folks reading this: am I being unreasonable, talking to Lenovo support one more time to request a 1 month extension of my warranty, given the length of time it's taken for repairs? I'll post the response Lenovo will give me tomorrow, as they've said they'll do.
One thing for sure: Lenovo's response will definitely influence my choice of brand from whom to buy a new computer (and it will influence the choice of my friends who've heard my issues, and maybe yours too). My particular repair problem may not come up often, but if it does happen to you, I'd be happy to know of your experience.
Thanks for sticking with me through the drama!

Premiere Pro CS6 importing/ audio and video problems

I recently recorded gameplay from my xbox, when i open this recording using windows media player it states that the video is 3 hours 30 minutes long, which is correct, when i then import this into premiere pro, premiere pro changes it to be 5 hours and 44 minutes long, when i then play this back it plays in slow motion and audio and video start to desync, i thought it may just be the source editor playing up so i made a clip and put it into the timeline and it still had the same outcome. The speed/duration are still on 100% so im not sure what to do, anyone have any idea as to what this is, or why it is happening?

Why does a Safe Boot fix my video problem?

After visiting my local Genius Bar twice (and getting two different answers), I erased and reinstalled Snow Leopard 10.6 on my late-2006 "white plastic" iMac.
I reinstalled the version of SL that came with the iMac, then upgraded it twice to OS 10.6.8. Software Updater says all of my OS components are up-to-date.
My video-corruption problems ("ghosting", "tearing", pixelation of icon, then the kernel CRASHES within 20 minutes) appear when I boot normally. But they permanently disappear when I reboot into the Safe Mode!
I've search Apple.com and every other site I can find without a clear answer to this:
What extensions, StartUp items, software daemons or gremlins DO NOT load in Safe Mode? Shouldn't one of them be the cause of my problem? Or does Safe Boot work on a hardware-level, too?
This happens on ALL accounts, both Admin and regular users. No external devices are connected except the wired mouse and wired keyboard.
I've zapped the PRAM three times, and I've unplugged it for hours. Disk Utility shows everything is good, too. There's about 50 gigs left on the internal 750 GB hard drive.
The so-called "Geniuses" both ran their Triage OS off an external drive and my iMac hardware passed ALL of their tests. One said it just needed a reinstall (a free fix!!), and the other said my video card is bad ($800, and I have to use an outside repair shop).
Can someone give me an idea how to proceed? I've been working in Safe Mode for days, but that prevents me from using: Sound, my home network, fonts, Preview, editing in iPhoto, etc.
Thanks.

Hi, Mike,
Thanks for the quick reply.
I read the linked post about QE, but I don't see how it could help me troubleshoot my problem. Could you clarify: is QE a piece of "software" (that is, a file -- like an extension)?
If QE IS a piece of software that is disabled in a Safe Boot, I should be able to move it to my Desktop and restart. If my video problem is eliminated, the QE software is the problem, right?
But then, if my problem is caused by a file/extension, why would the problem occur (and be eliminated in a Safe Boot) right after I re-installed the OS? Shouldn't all the System software be pristine right after re-installation? But since it's NOT fixed by the re-installation, it seems like a hardware problem -- like the expensive video card. That's what's confusing me.
So, I'm proceeding as if the problem is caused by a file being loaded into memory and I'm trying to disable the items that don't load in Safe Boot Mode one-at-a-time. I just need a specific list of what those items are (and their locations on my hard drive).
In OS/9, I used Conflict Catcher to do this automatically, but I haven't found an OSX app to do the same. So I'm trying to do it manually.
Please excuse my layman's terms. Any help is appreciated.

I just noticed that the video card crashes after i come back from sleep mode.
Here's the kernel log: http://pastebin.ca/2050145
and the Xorg.log: http://pastebin.ca/2050146
For this crash, unlike the one that happens when I view a flash video full screen, the problem can be fixed if i log off and log back on.

ITunes / Quicktime Video Problems With Windows VISTA

I took up Windows Vista as soon as it was available and initially had no problems with iTunes. Then later, video clips (those purchased from iTunes and those I had converted myself) started stuttering / freezing and eventually crashing iTunes and finally I lost audio as well.
Ayyway to cut a long story short, I have uninstalled / re-installed Vista now about eight times for problems with installing drivers for USB devices (I've finally solved all these problems). After the last install the first program I installed was iTunes, tried video and it worked flawlessly. Then, each time I added a hardware device or program I would restart Vista and retry iTunes video.
The first item I added was a USB thumb drive (as I had on all previous occasions to take advantage of Vista's 'Ready Boost'). The thumb drive is a 'Sony 2GB micro vault tiny', and meets the transfer speed requirements for 'Ready Boost', as soon as I had set the drive up for 'Ready Boost' I started having the same problems with iTunes video and Quicktime.
Removed the thumb drive, restarted iTunes and had flawless video playback again. Have tried this over and over with the same result.
So my question is, has anyone else had video playback problems with iTunes / Vista and found similar problems. Trying to tie down whether this is a compatability problem with 'Ready Boost' or the thumb drive used. I have also tried a Sandisk Titanium 2GB with the same result.
I am not sure exactly how 'Ready Boost' works, I thought it added memory that was used to cache page files to the thumb drive instead of to the HDD making a faster seek /access time? Which should make things faster. Another article I read today was talking about 'Ready Boost' being an affordable extension to RAM, in this case I could understand the problem as I would think the access to a USB 2.0 thumbdrive would be slower than that to RAM.
Any help appreciated, but I guess my bottom line is anytime I want to watch video on iTunes, I just pull the USB thumb drive .
PC Pentium 4 Other OS Windows Vista Home Premium

I have the same stuttering video issues with iTunes and Vista. While I have used a thumb drive to transfer files (not Sony) I have not yet messed with Ready boost. I have seen several others complain about the video problem, perhaps they will chime in as well. Unfortunately, your solution doesn't work for me. I pretty much ignore iTunes, waiting for the next version (only god knows when it will be released).
I do have an external firewire drive connected, I'll disconnect later today and see if that has any affect.

Power Mac G4 having video problems -green dots and pixelated lines

Yesterday my Power Mac G4 running OS X (10.5.1) started having unusual video problems. I started to notice green dots on the screen where the mouse pointer had been or where application windows had recently been. The severity of the video symptoms seem to vary - from a cluster of green pixels to slight amount of fuzz in text.
I'm thinking that this is a symptom of a problem with the video card starting to fail but I haven't ruled out the Apple Studio Display either. While the Mac was still under Apple Care support, I did have the video card replaced a few years ago due to symptoms that were much more severe than this.
Should I get a new video card? Could it be the display at fault? How expensive would it be to take it in to the local Apple store for diagnosis/repair?

Installed a new video card (ATI Radeon 9600) along with the "Apple DVI to ADC Display Adapter" - seems to be fixed now! Thanks for the advice!
