Display Dithering (poor quality?)

A couple display observations:
- On light gray screens, such as the first bootup screen, noise/grain is detectable.
- Once in Leopard, display dithering is apparent. For example, hide the dock and look at the darker gradients towards the bottom of the default screen background. Also, look at gradients, such as those in iPhoto's fullscreen viewing mode's toolbar
Have you noticed display dithering on the Macbook Air?

Hiya!
Gee...this is beginning to remind me of the screen problems that people were initially reporting with the iPod touch when they managed to get them . :S Perhaps you might want to try a monitor test of some kind to see how the colors on your screen are supposed to look? Something like this:

Maybe you'll want to see how your screen does if you load up that page first and look at the graphics on it. If something's wrong and you have to go to the Apple Store to have a Genius look at your MBA, you can try loading up this page to show them what's going on.

All the images from the webpages i visited was displayed with poor quality

i have been using firefox for a long time this is the first time i'm experiencing an issue with firefox. i'm using firefox ver.37 with windows 7. i have tried all the settings in the firefox but no use. I'm also used the google chrome but it too have same problem

It is possible that your ISP sends images compressed to speed up the transfer and adds a JavaScript to each page to make it possible to see images in the original quality.
If you want to see the original image quality all the time then you need to contact your ISP and ask what to do to opt-out of that service or see if there is a FAQ about it on the web page of your ISP.

I recently connected my new MBA to an ACER display using the appropriate Apple hardware to connect to a VGA port. The quality of the ACER display is poor- the image is not clear. How do I achieve the same clarity of picture as my MBA screen?

Welcome to the Apple Community.
AirPlay Mirroring requires a second-generation Apple TV or later, OS X 10.8 or better and is supported on the following Mac models: iMac (Mid 2011 or newer), Mac mini (Mid 2011 or newer), MacBook Air (Mid 2011 or newer), and MacBook Pro (Early 2011 or newer).
On the basis of the specifications you have given for your set up, mirroring should work.

Extreme poor quality in full screen preview and exported movie

I have spend evenings and evenings to create the content of a project.
After dealing with error -108 and extreme poor quality in full screen preview and in exported movies (extreme stuttering) I decided to install my iMac new again.
The error -108 disappeared, but the extreme stuttering still remained in full screen preview and in exported movies.
If I make the preview screen in the iMovie browser as big as possible there is nothing to see of any stuttering.
Now I am getting pretty annoyed and have no clue what to do anymore (how to solve this problem) .....
Anyone any suggestion ?
The orginal video was recorded with a Panasonic HD camcorder.
I do have a mid 2011 iMac with 16GB ram and 256GB SSD and 1TB HD with a complete clean installation
of OS X Lion and iLife. This configuration should be enough to create a proper movie :-(

Potentially, yes. The standard Preview is 1024 pixels, longest size. Some people (like Omke) have displays 2560 pixels longest side, potentially increasing file size by over 500%.

Display Resolution Poor in OSX while great in Win 7

I have a 2011 MacBook Pro and I recently purchased a Samsung SyncMaster TA550 monitor/TV that I was hoping to use as a monitor. I am able to get the monitor to work through a mini DisplayPort to HDMI convertor, but the resolution and color on the monitor is very poor. In order to check that I didn't just have a bad cable, I was able to bootcamp into Windows 7 to check out the external monitor. In Windows 7 the monitor works perfectly. Both the color and the resolution are flawless. Any ideas?

Keywords: MBP, macbook-pro, samsung, T24A350, T24A550, monitor, display, solution, optimised settings
Computer : Macbook PRO mid 2011 version (but I guess it will work for earlier and future models as well)
Monitor : Samsung T24A350 (also works for the T24A550 and other monitor/tv models)
Problem : Solve poor quality of the monitor screen if using default settings
When connected to the Samsung monitor/tv, the screen quality is very poor if using the default settings.
However with the following procedure/settings the screen quality of this monitor is excellent!
It took me quite a while to find the optimized settings for the Samsung monitor T24A350 connected to a Macbook-pro via the minidisplay port -> HDMI adapter -> HDMI cable -> HDMI IN 1 (Samsung monitor). It is in the manual, but I overlooked it initially. The confusion is that the mini display port apparently is a DVI port and needs a special setting to work properly.
PROCEDURE (see also page 21 of the English or Dutch user manual
1. Select Source on the remote control
2. Select PC
3. Select SOURCE -> TOOLS -> Edit Name -> Enter
4. When connecting a PC to HDMI IN 1 (mini display port) with DVI to HDMI cable, change the mode name to "DVI PC" from the pull down menu
I guess the same setting is required if you use the mini display port to VGA adapter. However I did not check this.

Poor quality text in PDF

I am using Acrobat pro X to produce an online brochure. I started producing the brochure in Corel draw using A4 paper size in landscape mode. When I created the PDF by the print command the general quality was very poor, both graphics and text. I experimented with various settings increasing the quality settings for images but it didn't seem to have any significant effect. I then tried placing some of the elements in a Word document and creating a PDF from this document, and again I found that the results were unsatisfactory, a bit better than from Corel but not very good. I have converted many Word documents to PDF in the past without problems. I started a new Word document and this time copied a template for a landscape brochure from Microsoft. This was already populated with some Text-and-Graphics. When I created a PDF from this it was quite good. It was not clear to me what the difference between my basic word document and this new one was. I went through the documents’ settings with a fine tooth comb and the only one I could find was different was the paper size and orientation. I then copied some of my graphics and text to the word brochure document, and this to converted nicely to PDF. I took a note of what appeared to be a somewhat unusual paper size and copied this to the Corel document. When I created a PDF it was now significantly better all the paper size was wrong. I went back from scratch with both the word document and the Corel draw document (those which produce bad PDF files) and carefully made sure that the paper size and orientation in the document matched the PDF settings. But the result was still poor in this case. It is not clear to me what is causing the problem although it does seem to be mainly text, the graphics are often okay. The text however is extremely patchy looking and very poor quality.
In the Acrobat settings I started with "high quality print" default setting and edited this. When I selected the fonts section there were no fonts selected for embedding. This surprised me as I would have thought high-quality print would automatically embedded all fonts. I selected the fonts in my document and embedded them and saved the settings, but when I went out of this dialogue box and straight back in it showed up with no embedded fonts. What's happening here? Is it for getting about my font selection? Or does this dialogue box when you re-enter it not reflect the current settings? Furthermore when I completed my modifications to the "high-quality print" default settings it asked me to save them as a new job options file which I did, but when I go to print a second time it never gives me the option of selecting these saved settings.
I have tried almost every permutation and combination of settings page sizes et cetera and I now tearing my hair out trying to figure out how to simply get a reasonable quality PDF file. Any assistance on these matters would be greatly appreciated.

Hi Michael
I am using Corel V 13 and Windows 7. The issue is not confined to Corel as I am also getting poor results often with Word as described. I also need to know about the font embedding as described above. Is it the case that if the fonts are embedded this
guarantees they fonts display sharply in the PDF? i.e. do the scatty fonts in the PDF prove I am not getting embedded fonts?
Corel does have a printer driver compatibility setting where you can set the target printer, but the PDF virtual printer is not available in the list.
Thanks

Saving a Project In Pages, Images Poor Quality in PDF

I have just purchased IWork 09, i am new to pages and so far find the software very handy and easy to use to make very attractive documents.
i have one dilemma though.
i save a (e.g.) poster in pages, but when i go to open it in PDF Preview, the images that i have inputted into the document are distorted or of a poor quality, when i open them in pages they are fine?.... also when i go 2 open the saved document in Adobe Reader 9, it wont open? i tried taking frames and shadows etc out just in case they are not supported, like in MS Word but still no luck. i have to send flyers for advertizment via e-mail to clients who are more than likely using Windows Xp or Vista.
if some one could help with
1. Getting my images to stay good quality
2. opening it in adobe 9
it would be very much appreciated

You can not see which programs have been involved in each compression, but as far as I know, at least some programs store information about both themselves (last edited by) and the compression level in the exif/iptc data.
The right way to work is to get as much data as possible off the colour capture in high bit and do the exposure correction getting into a normalised colour space either still in high bit or in scaled down 8 bit to save space.
The pixels should be left alone from this phase and out. It is not necessary to change a single source pixel either in matching to the display, the printer or the press. All of this is done on the fly in memory and not be changing the pixels in the disk-based image document.
As interchange file format for corrected colour captures stored in the normalised colour space, either use a linearised RGB space or high-bit CIELab. The file format should be lossless TIFF and not lossy JPEG (the way JPEG works internally is lossy by definition).
Live Picture and Apple Aperture are alike in the way they work. Rather than taking the pixels into memory for correction, which is they way Photoshop worked, they construct a colour managed proxy for manipulation and then provide for a rendering that is non-destructive.
Live Picture required ColorSync 2 and Apple Aperture is unable to work without colour management for the same set of reasons. Apple Pages is unable to work without colour management for the same set of reasons, although there are additional reasons for Apple Pages.
Just my ten cents,

Why poor quality AIC & Apple ProRes HQ video when compared to original video files!

First, I'm a long time PC user who has recently switched to Mac's and I'm rather picky about the quality of my videos.
Problem: I have HD video from a Canon HF S10 camcorder and Canon EOS 7D that looks fantastic on a PC... but looks very so-so once imported into a iMovie or FCE or FCP. I've tried all three programs using AIC and yes I've even tried Apple Pro Res HQ (FCP 7.0 log & transfer) and still end up with very poor quality mov files when compared to the originals. Part of the problem (or benefit of a PC) is that the PC actually plays the original RAW MTS/M2TS/MOV files without any trouble and and they look unbelievable. Where as my Mac has to import/convert the file to AIC or Apple Pro Res HQ... so no matter what codec I use, my Mac produces video that is not even close to what I get out of my PC.
My original RAW files are all 1920x1080 60i and are MTS files from the HF S10 and Mov files from the 7D. Even the original RAW Mov files produced from the 7D don't look as good on my Mac as they do on my PC. I even took a SD card with the original files down to the local Apple store to see how they look on a Macbook Pro and they still don't look like the originals on my PC. Also, all my comparisons are being done side by side on two 24" Apple cinema displays at full size (1920x1080) that are calibrated. What am I doing wrong and why the loss in quality? Any ideas as to why the quality is just so-so when compared to the originals would be greatly appreciated. Thanks in advance.

The thing that is wrong is that you are judging the quality of VIDEO on COMPUTER monitors. Properly calibrated or no...this is not how you do it. Calibration for computer monitors sets them right for PHOTOSHOP and color, not VIDEO and proper monitoring. Only getting a signal to a broadcast VIDEO monitor, or HDTV, will show you what you really have. And for that you need an HD input/output device or capture card...and the HDTV or HD monitor.
Computer monitors are never the place to judge video quality. Resolution is typically lowered to allow for full frame playback. Even if paused.

Poor quality Export for HD with moving objects

When I export from iMovie6 any moving image is very poor quality. I am using a Sony HDR-HC1 and trying to export at the highest possible settings.
When the image is still the quality is very good, but if anything moves the image goes "wobbly" and "jigsaw" like. Panning shots are hopeless and anyone walking in the shot goes wobbly.
The original capture image seems fine, so I assume it is an exporting problem. Exporting at lower setting, ie for an iPod, the image is great.
I have tried all different setting, some are better than others.
Can anyone help?

Your description of the problem - a 'comb' effect - sounds as if the "fields" which make up the resultant picture have been put together in reverse.
(..You don't normally see 'interlaced' video in iMovie's playback window - you normally see just a single field of the two, to make the picture clearer and simpler to display..)
[..A video picture's generally made up of two "fields" which each comprise half the number of lines down the screen: one field comprises the odd-numbered lines, and the other the even-numbered ones. Your exported video should be encoded with the lower (2nd) field first ..as described in this Apple document ..and the problem's mentioned here as well..]
However ..you said in your first post that "..I am using a Sony HDR-HC1 and trying to export at the highest possible settings.."
This is an HDV camcorder, and you didn't say if the original footage which you shot was HDV or normal DV. (HDV is recorded differently from normal DV, as it's recorded in a more compressed format, and it has to be automatically 'unscrambled' by Apple's Intermediate Codec while you're importing it into iMovie HD.)
It seems as if somewhere along the chain of importing>editing>exporting, the fields are being reversed, so that you get this jumpiness on replay when QuickTime tries to deliver a "highest quality" interleaved replay of both fields:
Ah ..sudden thought: you mentioned that you exported thro' iDVD: "..I have used iDVD by dropping it into a DVD theme and it seems to work ok, although the playback is a little jumpy, not quite as good I would have expected.."
You may have left the iDVD settings at their default 'NTSC' instead of switching them to PAL.
Check your iDVD Preferences ..that may be the problem.

Poor quality images on Slideshow

Hello all,
I recently downloaded Aperture from the Mac App store - seemed to good a bargain not to and I was already considering upgrading from iPhoto 08.
I imported all my pictures (along with the captions) into Aperture and created a slideshow from an album. I was quite disappointed to see that the image quality was really poor and very grainy. The photos themselves were fine in the album - but not so in the slideshow.
I thought this may have been down to importing from iPhoto, so I experimented by adding other images directly into Aperture. The same slideshow quality issue arose. I also possess a MacBook Pro and decided to re-perform the steps described above. The images and slideshow are absolutely fine on my MacBook pro.
I wish to maintain my photo library on my main iMac and will be very downhearted if Aperture cannot give me the same picture quality on slideshows that I achieved in iPhoto. Can anyone help me figure out why I'm suffering from poor quality images in slideshows on my iMac?
Thanks in advance,
Simon.

Hi Simon,
Aperture uses the image Preview in Slideshows:
_About Displaying Sharp Images in Slideshows_
To display slideshows at the best quality, you should set Aperture to create high-resolution previews. In addition to setting previews to their highest resolution, you should also use full-size previews to prevent upscaling with large displays. If previews are not available, images in the slideshow may not be as sharp as they would be otherwise. For more information about creating high-resolution previews, see Working with Preview Images.

'ken burns' poor quality interlacing jagged

This post is to document issues with 'Ken Burns' rendering in Final Cut Express 4 and some workarounds and possible bugs in software I found.
Similar posts about this issue:
https://discussions.apple.com/message/5207261#5207261
When I import images into final cut express and apply keyfram effects with panning and zooming a.ka. the 'Ken Burns Effect' I find that image quality is very poor. This occurs in most BUT NOT ALL images in viewer and canvas windows as well as rendered footage. The video issues are severe interlacing artifacts (horizontal blurry lines) as well as motion jitter along edges.
Many other users on the web suggested the following, which did not work for me:
-Avoid using JPEG files because their compression introduces artifacts which causes problems for Final Cut
I have found both JPEG and TIFFs have trouble with Ken Burns, although I do have certain TIFFs that seem to work.
-Using different software to render ken burns panning.
This seems silly to me. I find that the integration of pan,zoom necessary for fine tuning during editing. This would be extremely time consuming to separately generate each pan/zoom clip and import. I have heard that some software has high-end smoothing, but I am satisfied with the images that do pan and zoom correctly in Final cut.
-Adjusting Field Dominance in the clip properties to none
this was already set on my clips
-Adjust render settings.
I saw a 1001 rendering 'recipes' offered up to fix image pan/zoom issues. None worked
Things I discovered
Ken burns effect looked great when the image was in a transition, but bad when it was not. For example: Imagine a 5 second cross dissolve between regular video and ken burns motion image. When image becomes clearly visible in the latter 2.5 seconds of the transition it looks excellent while panning/zooming. When the transition finishes there is a sudden change to poor quality in the pan/zoom.
-The render bar on top of the timeline is dark-green for good-looking images, which according to the final cut manual, means 'no render necessary'
-There was nothing special about these render-not-necessary images that I could find in resolution, settings, etc.
-Good looking images were jpegs, gifs, and tiffs
I tried converting other images and reimporting, no luck
-I can make the ken burns look good for all images by playing the movie in the canvas window and setting it 99% zoom.
Any zoom level other than 100% looks good.
-This seems like a bug to me.
Eventually I just used a screen recording application called screenflow to capture my video playing in canvas window at 99% in real time.
This worked.
Hopefully someone can explain why rendered images never look good and what format works to get the dark green line and avoid rendering all together and these problems.
I don't mind converting file formats beforehand as long as they work well

The render bar on top of the timeline is dark-green for good-looking images, which according to the final cut manual, means 'no render necessary'
This is misleading. It simply means rendering is not necessary for playback. It does NOT mean that the material does not need to be rendered.
100% zoom level is as close to how your video actually looks that a computer monitor can display.
You never said what format you're working in.
You always have to render still images. You're making video, and they're not video.

I must be doing something stupid: Very poor quality DVD rendering!

I am new to Apple products and after trolling this forum, I was able to create a DVD using iDVD on my Mac mini Core Duo - 2Ghz model. But, the video is of very poor quality (compression artifacts). I am lookging for guidance to creating a better video quality. But first, let me give you some background...
I have created enough DVDs for my home videos captured both from my S-VHS camcorder and min-DV camcorders (both PAL and NTSC) using Pinnacle Studio (buggiest software in the world) and Adobe Premiere Elements under Windows. I have clear expectation of video quality and understand the quality differences between various standards.
I have a fairly new toy - Canon Powershot TX1 digital camera which is an amazing compact camera that shoots 720p video @ 30fps and stores them in MJPEG format. Very good optics (10x optical image stabilized zoom). The only con is that it has very poor low light shooting ability.
The steps I took to create this DVD...
1. Import the .avi and .jpeg files from my camera into iPhoto library.
2. Use iMovie (all part of iLife'08) to stitch the avi clips and also some of jpegs. Added transitions, titles and music in iMovie.
3. Also, added some of my old low resolution avi files (from my older Canon camera - probably in 640x480 resolution).
3. Exported it in the largest file mode (960x540) which created a 1.8GB file.
4. Opened this movie file in Garageband and added the Chapter markers.
5. Shared it with iDVD which automatically launched iDVD and showed the chapters in very nice scene selections menus.
6. Invoked the Burn menu to burn the movie into a DVD using iDVD.
Am I using the right methodology (I want the chapters)? I also observed that an earlier project which was pure 15 minutes of 720p content created a 4.7GB size exported file from iMovie whereas this current project has 51min of avi (of which about 10min is low res and the rest is in 720p format) and 12min of still photos produced a 1.8GB file when exported. This clearly tells me that the exported file is of poor quality. Why did that happen? Was it because I mixed the content and included low res videos?
I should probably try creating a DVD from the pure 720p content and see how that looks.
Any pointers would be a great help. BTW, the mac mini, iPhoto and iMovie forums are just awesome. The quality of posts and responses is very high.

Thanks a lot, F Shippey.
I exported it as a .dv file and then I was able to produce the DVD correctly with the Revolution theme and 11 chapters. I haven't done any editing any clips yet in iMovie. In most cases, I will not need to do that in most cases as the Canon TX1 creates individual avi clips every time I record and stop a recording. Having used a camcorder for over a decade now, I know how silly most of the recordings are.
I will be rendering most of my videos as h.264 so that I can use the mac mini as a media server instead of using DVDs. I have to rip my own DVDs as h.264 soon (back to handbrake).
PS: While creating my first DVD in OS X + iLife'08 tools, I noticed the following bugs:
1. The clips disappear from the display in the editing window when the project becomes large and I had to zoom in and out to make them reappear. I verified that I wasn't viewing past the end of the last clip. If I hover the mouse in the blank window, it will show the clip in the preview window on the right.
2. I had 11 chapters marked in Garageband and then I shared it with iDVD, it created two pages of scene selections with 6 chapters in each page. In the 2nd page, it added a random window (unconnected) for the 12th chapter that I didn't have. I didn't check for that and so my finished DVD has this weird 12th chapter with a copied moving clip in the window, but when selected, it doesn't do anything.
These two bugs are way few compared to what Pinnacle Studio threw at me.

Poor quality PDF output

Hi,
I have noticed that the PDF output when using Rome on Windows is quite poor and is far inferior to an outputted PDF from a Mac.
When you use a drop shadow on a piece of text it is displayed in low quality (even if the high quality option is selected on the filter). This is not the case if you generate an interactive PDF on a PC where the text is smooth and crisp with a beautiful drop shadow.

Hi Mike,

Poor quality of all exported media

Just started using a brand new Edit PC with PP CS4 and Matrox RTX.2 Imported AVI is very good quality and sharp when viewed on the timeline and on the output monitor, however, when I export any clips, the quality of the video appears flat and lifeless, as if the contrast has been reduced and the brightness increased. The exported files are played on Windows media player on both this machine and several others - the result is the same.
I want to export to windows media and have used 'PAL widescreen source - high quality download' preset and windows media 9 (and several others) but the result is the same whatever I use and however I tweak the settings. Also, if export using Microsoft AVI instead, or mpeg1 or mpeg 2, the result is always the same when I play the exported clip in windows media player.
I could convert the avi file through an external encoder to wmv, but a) I want to export direct from the timeline and b) the exported avi file has the same poor quality and c) that would be defeating the object of having CS4.
System is Vista, 4gb ram, 2 x quad core Xeon processors, ATI Radeon card, MAtrox RTX.2 v4.00x/ Prem pro CS4
Any ideas? would the update to Matrox 4.01 help? What am I missing? My old prem pro 1.5 exported crisp quality video every time.
Many thanks

I've been having similar issues with mpeg2 encodes in CS4, working in ntsc standard definition -- also on a hot new machine with the RTX2, Vista 64, 12 gigs ram, etc. In my tests I can get a sharper encode either using PP 1.5 on an older machine, or using a freebie stand-alone encoding program called WinFF.
In my case, I've actually been able to get sharp encodes in the matrox avi format -- those turn out fine for me. But once it goes to the AME for mpeg encoding, then it gets fuzzy. I've tried the 1 pixel offset, but that hasn't really made much of a difference.
The thing I like about the matrox card is that it gives me video output to an external monitor from the timeline as well as the source window within Premier CS4 ... and I assume it probably speeds up some of the rendering. I just don't feel like I'm getting a really good quality image when I'm using the windows media player or other players on my computer monitors. So I really rely on my external CRT monitor to judge sharpness, density and colors, as well as titles.
What are you doing for output monitoring, now that you've pulled out the RTX2 card? I've been wondering what other options there might be that would work well with CS4.
You might check out WinFF -- it seems very fast and so far it's been working well for me. I'm not in PAL. so that might make a difference ...
On the brightness issue, it might be worth checking to see whether you have the latest video display card drivers -- another user found that made a big difference in image quality. However, I don't think in his case that it was related to his mpeg encodes.

Poor Quality of PDF pages with Folio Builder

Hi,
New to DPS. First impressions are very good.
However, when adding an Indesign page to Folio Builder as an article with the format set to PDF(to enble pinch and expand on iPad), the tiff images that are included in the Indesign page are displayed in very poor quality??
When I change the format to PNG or JPEG, in the article, the same images are displayed on the iPad with excellent quality - however, I dont have the pinch and expand functionality, which is what I require!!
I would really appreciate any solutions or suggestions on how this issue can be resolved.
Indesign CS5.5, MAC OSX 10.7, iMac
Regards,
Iain....

Which iPad are you viewing your test articles on? Remember that the resolution for iPad 1 & 2 is 1024px x 768 px, while the iPad 3 resolution is 2048px x 1536px. Your images need to be formatted accordingly. Also check your image scale parameters. Anything above 100% scale of the original image will reduce the image quality. You can check this in InDesign before you ever test your article on the device. Simply press Command+1 to view actual pixel size and set your Display Performance to High Quality and you should be seeing something very close to what the final result will be. Also check that your images are RGB as well. Hope this helps.
