Pixel Distortion - HELP!!

I have a problem in certain pictures with pixels distorting in LR. Its not a preview problem because the distortion comes along if I export the file. Here are two sample side-by-side screen grabs:
http://clarkcreative.ca/l-psd_r-LR.png
http://clarkcreative.ca/l-psd_r-LR_2.png
Left side - Photoshop, Right side - Lightroom. (opened in PSD via lightroom edit command)
200% crops. Its a jpg capture. There are no adjustments/presets applied to either. I have tried to re-import renamed/tiff but I get the same results. Can someone tell me why this is happening?

An Intel Pentium 4.
I also noticed that those strange pixels remain uneffected when you do crazy things with the exposure, contrast, brightness, recovery, etc, even though the rest of the image gets altered. It's like they are holes in the images. It's definately a bug.
Good luck. I'll keep shooting RAW so I won't have that problem (Nikon D70s).

Cs5 - images have weird grid-like/pixelation distortion i cant get rid of! help!

i've just downloaded the trial of photoshop cs5 (it took ages mind you!) and when i go to open (or create) a file that is larger (eg 1000x750 pixels) there is this weird grid that distorts the image (it's not the grid you can turn off and on or the grid that shows the actual pixels). when i open a smaller file there is no grid and the image is perfectly clear and normal - but when i zoom out there is a grid. also, when i'm zoomed out (eg 66% but sometimes from even 200%) the distortion happens, whereas if i zoom closer it disappears.
it doesn't distort the image itself, but distorts the colours in parts of the image.
i've experimented enlarging the canvas of a smaller image and placing a larger image into it on a different layer, but then the grid affects not only the larger image but the smaller as well, like it is stretching the colours to the edge of the canvas, or trying to pixelate/fuzz the image. however the grid doesn't affect the whole canvas, just the bits above and to the side of the larger images (mostly).
also when i zoom in/out gradually the squares of the grid enlarge and change size (both bigger and smaller).
so i don't know what the problem is, and any help/suggestions would be much appreciated as i need to use the program for a uni assignment due in a couple of weeks!!
thanks!

Hey- I have the same issue. When I started using cs5 I noticed this grid/distortion right away. At first I thought it was my wacom tablet (I use an Intuos 3) but its not. Its very annoying because I cant put my fingure on why this is happening. Anytime I ask a friend about it who normally knows alot about photoshop they tell me its that grid option thing which I have already turned off. I have included a screen shot of what the issue looks like. Any ideas anyone?

Saving object for web - pixelated & distorted

Trying to save an image for web in Illustrator. It's a "browse" icon that we use for our product. We're recreating the icons to look more "flat" with the outline state as the inactive and the fill state as the active. Here's what I get when I export it for the web as a .png.
**image when it's zoomed in using Preview
**image at it's normal size using preview.
**image after flattening transparency
I've tried to optimize, not optimize, flatten transparency, rasterize -- none of it's worked to make this icon look any better. The only thing that came somewhat close was flatten transparency -- that helped with the pixelation but the boxes all became distorted. Please help!

Image at normal size using preview is the most helpful piece of information. Would be good to knwo your exact pixel dimensions.
Did you use align to pixel grid? Try saving as .gif. This is as good as you can get with such a small size.

IMac 27 - Pixel Distortions

Hello community,
I hope someone can help me out with my bad situation. Since I bought an iMac in April 2010 - I really had NO problems and was so happy with the product.
Last week unfortunately a strange error happend SUDDENLY.
After I turned on the iMac, approx. after 30 mins of running a pixel error, distortion are seen on my screen. (Please see attached images).
I tried out a lot now and I still have these annoying error which I can't get rid of. Working, surfing on the iMac ist not really "possible" anymore.
My System:
iMac Intel Core i5 27 inch
Snow Leopard 10.6.8
CPU 2.66 GHz
Memory 4 GB
HD 1 TB
Graphics Card ATI Radeon HD 4850 / VRAM 512 MB
Unfortunately I have no Apple Care anymore.
What I've done so far:
- Restarted several times (still getting the errors)
- Unplugged it two days from power ressource (still getting the errors)
- Reset of PRAM and VRAM (still getting the errors)
- Installed all Updates (still getting the errors)
- Repaired Rights of the Harddrive (still getting the errors)
- Apple Hardware Test (no Hardware errors detected, but still getting the pixel errors
- Formated my Hardrive and installed Sow Leopard from the OSX-Installation Disk (still getting the errors) (also after updating all files through Software Update)
- Reset of Chaches....
BUT starting the iMac in SAFE MODE - the pixel errors are GONE.
What's the problem, can anybody help me out? I guess updating to 10.7 (Lion) won't be the solution. That would be too easy.
Thanks in advice and looking forward to your answers.
Regards from the alps
Stefan

That sounds like an over heating graphics chip, because it seems to starts after around 30 mins.
Get the iStat Pro widget to monitor and record your iMac's internal sensors, (GPU is for the Graphics Chip) and take some readings every 5 mins or so during that fisrt 30 mins.

When was the last time you cleaned the iMac's bottom Air Intakes?
1. Shutdown the iMac
2. Un-hook everything, power & all other devices
3. Gently lay the iMac face down on a soft cloth or towel.
4. Go get out the vacuum cleaner, hose and brush attachment.
5. Seriously vacuum out the iMac's botton grill work and vents on the back.
(including under the RAM cover if your incline)
Now then, take and record some temperature readings?
Unfortunately if the problem persists, then you will need to take the iMac in for service.

Exporting through Adobe Media Encoder as MPEG2-DVD but quality is pixelated. Help!

So, I am exporting my project through media encoder - MPEG2-DVD, Quality 5, NTSC, 29.97 drop frame, Progressive, Standard 4:3, VBR 2 Pass, 7.4697, 7.4697, 8.0382, Frames 3 & 15. I have done this process many, many times. Today, I am getting this pixelated junk when I pull the exported file into Encore. It looks smooth in the window prior to export but then it comes out like this. I am using footage that I captured into Premiere Pro and animation created in After Effects. Can anyone help?

DVD from HD720 is extremely pixelated- Please Help

Hi
I've shot a project with HD (HM171 on a P2 Card) and edited as DVCPRO HD 720
I've made the film as a multi image (3 layers/images on one screen) and tried exporting to DVD Studio Pro on a number of formats but all results are very heavily pixelated. (3 layers each at 27% size)
There is a major amount of jagged edges and blockiness to the images and I don't know how to fix this.
I've exported a normal single channel/single image piece at normal size and it's looked ok.
The settings I've used are to let DVD Studio Pro encode in SD settings by creating a quicktime export using the current FCP sequence settings.
I've also encoded through compressor using best quality DVD settings mpeg2 2-pass and still it looks blocky
Please can anyone help me! I'm so stuck with this

How's the quality of the FCP exported self-contained movie?
In Compressor, make a duplicate of the Best Quality 90 minute preset, turn ON Frame Controls and set the Resize to Better or Best, select Progressive and Better.
What frame rate do you edit at? If your trying to compress 60p MOV down to 30 DVD, Compressor may struggle to maintain quality. Better to start with 30p or better yet 24p in FCP

Illustrator CS4 - when I save for web my vectors are pixelated. Help!

I recently updated to CS4 (I know, I'm still behind the times) but ever since when I 'save for web' my vectors appear pixelated. It seems worse when I want a transparent background. My images are for web and this just won't do.
I've read a lot on this and can't seem to fix my problem, but here is what I have tried: Anti-Alias is checked, view > pixel preview, view > overprint preview, object > rasterize, and probably a few other things. If anyone can help me with this issue it would be GREATLY appreciated!! I've attached an image so you can see what I'm talking about. I created this schematic in Illustrator CS4 and saved for web with a transparent background and, as you can see, it appears pixelated everywhere.

I'm not sure what you're looking for but here is my save for web options. Let me know if you're looking for something else. And thank you for trying to help!!

VGA cable pixel distortion with Acer Monitor

Greetings:
Here is my problem:
     1. With my home office configuration, my MacBook is needs a 10ft cable to reach my monitor.
     2. Because of this, I cannot use the Acer monitor cable provided from the manufacturer.
     3. I've had to buy two different VGA cables and neither of them work.
     4. Here is the problem: For some reason, when you close the MacBook and use the external monitor, the display gets stretched. This only happens when the laptop is fully closed. When it is open and utilizing both monitors, it is fine. Also, When the laptop is open, I have more pixel display options available on the Acer than when the laptop is closed.
I bought a high end VGA cable and I know it is able to carry the correct pixels because my HP works just fine on it at 1600 x 900.
Is it the cable? Or is there a glitch with the MacBook????? Is there a special cable I need to order???? Please help!
Thanks,
Jon

Pixelated preview - Help!!!

I'm using color with a variety of codecs. With every one of them, the preview is pixelated. I'm using a second monitor (23" Apple HD Display) for my preview monitor). I don't notice the pixelation when I render out SD footage, BUT when I render out DVCPRO HD footage it is still there (even converted the footage to Apples Pro Res first to see if that helps-it didn't).
I would be happy if I could just see the image without pixelation in parked mode (while grading) and be able to render out HD footage without the pixelation.
I have changed the Proxy settings - that didn't help either.
Anyone?

Once you have your footage back into FCP Under your sequence settings make sure to choose upper field on the interlaced settings even if you are viewing progressive footage see if that helps, in my many hours experience using Color the preview is poor (slightly pixelated)as it doesn't handle footage properly (in my personal experience) possibly due to it been sourced from dvcpro hd given it only seems to display one field on a normal monitor regardless of settings in Color or whether or not it was progressive dvcpro hd footage to start with.

Images pixelated/distorted in ADE

I just downloaded ADE, and everything seems to be working, except that the images are all distorted. You can actually see part of the images below the distortion, but the distortion consists of what appear to be pixelated, thick horizontal lines of varying colors that block out major portions of the image and make them unusable.
Has anyone else encountered this issue? If so, was anyone able to successfully resolve it?
Thanks.
Just realized that I can insert images, so here's an example:

Read this FAQ:
Donald Gruener, "3.1 - Importing and Placing Graphics into PageMaker" #1, 17 May 2002 8:11 am
TIFF is the preferred raster format.
EPS should be OK with a postscript printer (e.g. PDF), but PM's preview is poor.
PM7 will accept AI, but only up to Ver 8
John Davies, "3.11 - Importing Adobe Illustrator Files (*.AI) and how they differ from *.EPS" #1, 7 Dec 2003 7:46 am
Remember PM is archaic. Your client should be using InDesign by now.

Envelope Distortion help?

I am trying to make an envelope with 2 objects. One is a symbol set of circles, and another is a patch of stars. every time I try to make the envelope, it keeps saying that there needs to be a single path, I'm assuming that means the circles need to become 1 path somehow. I don't know what that means. I've read the directions over and over and I don't understand what I'm doing wrong. I hope someone can help.

uploader still isnt working for some reason, so I'll try to explain it better.
I have 2 objects, a circle and a patch of stars.
I used the circle and created a symbol set which I colored and grouped.
I grouped all the stars together and placed the group of stars on top of the circles.
Do the stars need to be made into a symbol set too?
Then I tried to use the envelope distortion but it kept saying there needs to be a single path. Sorry I can't upload a picture...

Macbook Pro Display Problems - Pixels distorted and jerkig up and down

I took a video of a problem my Macbook Pro is having... I am going to take it in for repairs but am wondering if anyone else has had this problem or if there are any ideas as to what it might be. It has been getting progressively worse over the past couples weeks. At first, it would not start happening until my computer was on for a while. Now, it happens all the time, but it only distorts the windows open above my desktop... not the desktop itself.
Here's a link to the (terrible) video I recorded: http://www.youtube.com/watch?v=OfmmaoDBWLQ
Any ideas? Thank you!

Glad to help! Sometimes it's good to play with UA a bit, just so you can recognize what's going on if something gets activated. For example, somebody's cat managed to turn on the "White on Black" feature, which drastically affects the appearance of your desktop. I don't know how features in UA keep getting turned on accidentally, but it happens.

I have pixel distortion in my window bar

it looks like this, the distorted pixels are in the left and right corner
another sample:
it happens again and again, no other sideffects yet.
what to do should i run to a apple dealer and get my board switched,
i know this effect from former slowly and painful dying GPU's
regards

If you have Apple Care call them. If not and you want a "do-it-yourself" fix, do a Google search, see Youtube's "How to" video tutorials and Do-It-Yourself Laptop Repair. Otherwise, take the computer to an Apple store or an AASP. Whichever is more convenient for you.

If you do not want to upgrade to Snow Leopard or Lion, you should at least udate Leopard. Use Software Update to update your os and anything else that needs to be updated showing up in SU which I know must be a whole lot of stuff!!!!
