Why the poor previews?

Hi all,
I'm really enjoying LR3 but a few things are very annoying imo. I'm sure this has been addressed (and answered) before but I can't find it.
When I open/zoom an image from the Library grid the preview looks poor and unsharp. Only when I zoom in 1:1 and back the preview looks good. Why is this? I have set the the Preview Quality on 'high' and on 1440 pixels, the size of my screen.
Also, when I work with the adjustment brush in Develop for a while LR seems to get slower and slower and not able to keep up with what I do. Arrgghh...
My ThinkPad laptop is brand new with an Intel Core i5, 4Gb and 7200rpm HD and should be speedy enough.
Richard.

I've noticed the same behaviour. It is rather odd and a little irritating.

Does anyone know why the text preview still shows in notification center when show preview is turned off in settings

I have my text message preview turned off for notification center but text preview still shows anyone know a way to fix this problem

Have you tried a reset. This will not affect your data, it is just like rebooting your computer. Hold the sleep/wake and home buttons together until you see the Apple logo and then release. After the phone restarts, see if that will help.

Why the Poor Run Time Refresh Quality?

Good day,
I've developed a little piece of software to monitor a small amount of inputs from NI DAQ hardware (4 inputs). On my developing computer, everything looks fine but this is not the case on the Run Time computer. Usually the software starts looking fine, but when anything gets redrawn (whether it be from a button press or from another window being placed over it), the image quality is poor. Kinda looks like the color palet in whatever redrawn area gets dropped to 8-bit. I notice this only in the Labview application. Everything else on the PC looks fine when redrawn. Attached is a little image that compares two buttons, the top one having been redrawn. Note the quality difference.
Developed in LV 7.1. Using the RT drivers installed from the NI-DAQmx driver disc (v8.3) (RT 7.1.1)
I've tried rebuilding my app, re-installing my app, re-installing all NI software (on the RT computer), updating video drivers.
Any ideas and help as always will be most appreciated.

Sorry I didn't respond right away. Got busy on other matters and this issue slipped my mine. Developements have happened...
On coming back to this project, the HD on my laptop died (development comp). Never had any display issues on this machine (was previously posting about issue on computer where app will be run from, where issue still exists). After re-installing everything on my new HD, I'm now experiencing this problem on my development laptop as well.
I'm using an IBM Thinkpad T30 (P4-M, 2.0GHz, 256MB, ATI 7500 Mobility). So it used to display fine on this machine, now it doesn't, and I'm experiencing the same symptoms: grainy display from what appears to be a lower resolution colour palette (maybe 256).
Here too, this is only an issue within the development environment. The startup Labview splash screen looks fine (again LV7.1), the blue bar along the top of all windows transitions from the darker shade of blue to the lighter shade, properly. This issue is on the toolbar and in the developement area within Labview only.
It's weird how this appears to just come or just go. I don't remember who, but somebody here mentioned how their problem just stopped as suddenly as it started. And as this is localized to LV, I'm inclined to think this is not the video card, but perhaps some file/driver/dll that perhaps gets modified/updated without direct visibility. I briefly had this issue aswell on an older Toshiba laptop about a year ago, but it eventually "fixed" itself aswell (don't remember model/specs of older Toshiba).
Anymore help and research into the issue will be most appreciated.

Analog capture into DV format. Why such small files? Why the poor quality?

I am capturing 8mm video cassettes with an "ADVC 3000" converter, using an S-Video into the converter and then via FireWire into my PowerMac G5.
All is almost going well, but the files seem to take up so little space on my Hard Drive. That's a good thing, but I'm wondering if it's recording into Digital Video or not since the files seem so small. Smaller than normal for DV at least, or maybe I'm just paranoid.
In the scratch files, when I press Command-I for information, the Codecs on the QuickTime files are DV/DVCPRO-NTSC, Interger (Big Endian), Timecode.
So I'm guessing they are DV files even though they look like crap.
My question is this though. When I put these old analog tapes on iDVD, burn it, and put it in my DVD player, the quality of my video looks pretty crappy on my hi-def television. But when I watch them on my computer in a tiny window (the tinier the better), the video looks great. A large window, or my Television, gives a bad picture. My theory is that it's my hi-def television and computer monitor, and that on an old Analog TV set, the videos would look much sharper.
Should I play 8 mm analog video, converted to DV in Final Cut Pro, on an older Analog T.V. set for best viewing results?
Anyone have any comments to share on the science of this?

Yoshiman,
Forgive me if you did know this, the TBC is a Time Base Corrector. (I am pretty sure corrector is right). Anyway, the 8mm has time code striped on it with the image information. If the playback device is not able to read the time code, the picture quality suffers. (remember tracking adjustments?).
The TBC will intercept the time code coming from the tape and provide accurate, consistent time code to the system. I use one from DataVideo, and have been happy with it whenever I have to work with old tapes. If you have a lot of tapes to capture, you might look into one.
My two disclaimers: this is a very general explanation, I simply don't know the physics of what's going on, and secondly I am not a power user of FCS, but have gotten so much from this forum I am trying to give a little back. Take what I bring to the table with that in mind - I'm proficient, but not an expert.

Why the poor wifi performance on iPhone 5

I am using my iPhone 5 and five feet away my wife has her new iPad. Both on the same wifi. The iPad is showing three bars but the iPhone 5 goes from two to none. It sometimes looses all wifi signal and drops off to cellular. I thought one of the recent upgrades to the iOS was supposed to fix wifi reception problems on the iPhone 5.
Any solutions?

Some added info for my question. We have an Airport Extreme on our computer and an Airport Express in the area where we sit to improve the signal. My wife's iPad is about six feet away from the Express; I am about two feet. Her signal has to go through me so I think the iPhone reception should be stronger.

AE CS4 - why such poor RAM preview on my FAST machine?

Hi all, I just installed After Effects CS4 - I have a smokin fast mchine: quadcore Zeon 3.20 GHz, hyperthreading turned on, nvidia quadrofx 3800 with current driver, 12 GB DDR3 RAM, windows 7 64bit ... can you PLEASE help me troubleshoot a problem: even on the simplest compositions, a moving picture or a moving piece of type, the RAM preview stutters along, the current time indicator hops along at a choppy pace, images in the frame dont look like they're moving smoothly, and all i get is about 6 seconds of RAM preview ... seems to me that I used to get better performance on a MUCH MUCH slower machine under windows XP ... i have looked around the forums and seem the advice on multiprocessor options and the like, but nothing I do seems to help ... do any of you have any advice for me to improve my performance??? if you have any questions about my setup or preferences, let me know, I will be on this until I get what I expect out of my (otherwise incredibly fast) machine

Hi Todd, thanks again for your reply ... FYI, I bought the FX3800 for Avid editing, for which it is the qualified video card, and supports distributed processing in the Avid along with my DX HD hardware BOB - I had hoped it would work well with After Effects, too, but I do understand the Adobe is very transparent about the fact that, as long as your card has OpenGL support, probably best to sink your $$$ into more RAM or faster CPU .. but to stay on topic, I am just very stunned that I am not getting better playback with my system ... I have the most recent Nvidia drivers ... I have 2 NEC 2490WUXi2 each connected through DVI-D to my video card, each runnign at its native 1920x1200 res, 59 hertz ... the programs I have installed are Adobe CS4 Production Premium, Win7 64bit, MS Office 2007 Enterprise, latest version of Quick Time, Media Player version 11, and NERO 9 ... you dont think that one of these video player apps (like media player or QT) are messing with my screen performance do you? what about Nero 9, have you heard any compatibility or display problems associated with this app? would unistalling any of these programs be a troubleshooting technique that you'd attempt?
Finally, when you say "an issue with a bottleneck of drawing to the screen" what do you mean exactly? 'cause this kinds sounds like a goood description of what I am seeing ... what might be the cause of such a bottleneck, I am willing to try anything ...
Thanks, sir, for your reply!

Subject: AE CS4 - why such poor RAM preview on my FAST machine?
Just one thing to cut down a frequent misconception:
Your nice graphics card doesn't do much for After Effects performance.In fact, trying to use OpenGL for rendering (including rendering of previews) can cause problems.
I recommend turning OpenGL rendering off for all but interactions. I.e., choose the http://help.adobe.com/en_US/AfterEffects/9.0/WSAF696587-2D81-42e2-B248-4C5C2B7D3614a.html and turn off http://help.adobe.com/en_US/AfterEffects/9.0/WS3878526689cb91655866c1103a4f2dff7-79e8a.htm l. OpenGL is not compatible with Render Multiple Frames Simultaneously multiprocessing.
I'm not saying that OpenGL is your problem. Rather, because you mentioned your nice graphics card, I just had to stress that you need to forget about that with regard to After Effects. It's not really relevant.
It may be that the jerkiness is an issue with a bottleneck of drawing to the screen. (I don't know, but it's possible.)
Your hard disk being too slow wouldn't be an issue with RAM previews, since the frames are all cached in RAM.

In CC214 PS Why has adobe removed the "print Size Button" And why have they made the Brush preview window so small you can't see the effects to accurately adjust them?

In CC214 PS Why has adobe removed the "print Size Button" And why have they made the Brush preview window so small you can't see the effects to accurately adjust them?
These two things need to be remedied in their upgrades because It's become such a bother I've had to revert to older versions of PS.

Yea, and it's a pain to get to. What was the rational for removing the print size button? With the magnifying glass tool selected in older versions of Photoshop you would get a button that says "print size" right next to Actual pixels, Fit Screen, Fill Screen. Now I have to go out of my way and dig for it if I want to see the print size. Of all the buttons you could have taken away, why not fill screen? I never use that.
Besides the point I just downloaded the Oct Upgrade for PS and surprise! Nothing has changed and these are two big black eyes on newer versions of Photoshop. The Brush preview window is unchanged in CC but in CC2014 it's basically worthless. If you apply a texture to a brush you can't properly see the scale of the texture, the spacing, scatter, etc...

Try:
- iOS: Not responding or does not turn on
- Also try DFU mode after try recovery mode

- 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.

Why is the Lightroom preview folder so big, even after purging the 1:1 previews?

1:1 or full-size previews take up a large amount of HD space, often many 10's of GB's. This is why building them on demand is an alternative to building them up front, and why you have options for auto or manually purging them. That said, it may not always be possible to delete 1:1 previews - more later.
Standard-sized previews are based on the pixel size option you chose in Catalog Settings. You have 4 choices: 1024, 1440, 1680 and 2048. If all you want is standard-sized then choose a size equal to or greater than your screen size. Lr also builds smaller versions at the same time. These are used for the thumbnail, 1:2, 1:3 and 1:4 zoom levels. Adobe call this the "preview pyramid".
1:1 previews will not be deleted unless your chosen standard-sized preview is less than half the size of the full-sized preview. For example, you have images with pixel dimensions of 3072 by 2048 pixels (6MP camera such as Canon 10D) and have selected 1680 pixels for standard-sized previews. Since a 1680 pixel preview is more than half the size of the original the full-sized preview will be kept, even after using the purge 1:1 preview command. Had you chosen 1440 pixel for standard-sized previews then the full-sized would have been purged (i.e. 3072/2=1536, which is greater than 1440). Now take the example of a larger camera, say a 8MP camera such as the Canon 1DMKII with an image size of 3504 by 2336 pixels. With the standard-sized set at 1680 pixels the full-size will again be purged (i.e. 3504/2=1752 pixels, which is greater than 1680 pixels).
Another thing worth mentioning - Lightroom will usually delay purging previews for deleted images until after the application has been closed and reopened, even then it might take a few minutes to clear the purged previews. The idea here is to ensure the previews don't get deleted whilst there's still a chance that they may be needed (e.g. you removed images by mistake then use Undo command to reinstate them).
Hopefully above explains why Lightroom doesn't behave as you expect. If it makes your head spin, think how much mine spun when writing it.

The chance of an answer is inversely proportional to the length of the posting. ;)
You do not indicate what your preview setting was while you accumulated a 12Gb preview folder. Nor do you indicate how many images are in your catalog.
Given your screen size of 1280 (laptp?) I would set the preview size to 1440 since this is still far less than half of your D3 images.
Cropping - I'll safely guess - has no effect on your preview size choices.
I confess that preview sizing and purging is confusing. I avoid the confusion by shouting "more disk, mama".

Why the size of the tif file is different in photoshop workspace compare to the Preview in Finder?

1. Why the size of the tif file is different in photoshop's workspace compare to the Preview in Finder?
Please look at the screen captures.
Bottom left panel of Photoshop's workspace.
Finder's Preview.
2. I have an imac with 8gb ram, and assigned 6gb ram to photoshop use. But when I worked on a 24mb tif file, photoshop was lagging. And at the bottom left panel of Photoshop's workspace, the doc size is something/1gb. The tif file is only 24mb, why is it slow in photoshop? I have a lot of ram.
Let me know, please.

Thank you MIchelPM for giving me a very detailed explanation.
So I understood why the photoshop doc size is bigger when working in photoshop.
Regarding to your questions:
1. How full is your Mac's hard drive?
    Not even 30% full, I even have a 1TB backup hard drive connected.
2. How many applications do you run simultaneously in the background while working in another application?
    I usually only have photoshop or illustrator opened. Sometimes I ran 3-4 tif files at the same time, but when a big file (ex. 24mb tif) gets very slow, I closed all other files and programs, and "purged all" in photoshop, yet that 24mb tif file was still slow.
   I checked photoshop's ram and cpu usage in the activity monitor. Rarely photoshop's cpu usage would hit 100. But when I worked with the 24mb tif file, it would used all the ram that I've allocated to photoshop.
But the myth is, my coworker who worked with the same file in CS4 with only 4gb ram in their imac don't have photoshop slowed down, when I have double the ram and CS6.
3. What year, screen size, CPU speed of your Mac?
   I have 27" imac,
   • 2.9GHz 2.9GHz quad-core Intel Core i5 processor (Turbo Boost up to 3.6GHz) with 6MB L3 cache,
   • 1TB (7200-rpm) hard drive
   • NVIDIA GeForce GTX 660M graphics processor with 512MB of GDDR5 memory
4. What version of OS X is your Mac using?
    Mountain Lion with the latest updates.
5. What version of Photoshop are you using?
   • Photoshop CS6

After upgrading to OSX Mountain Lion the movie preview app has disappeared. Anyone know why?

The movie preview app that had a red chair as an icon has disappeared from my tool bar after upgrading to Mountain Lion. Does anyone know why this happened?

Why when I preview the ebook on iPad it's impossible to zoom the page without rotate it?

Hi Frances. To be able to rule out your adblock addon from being the problem on that site do this: go into 'add-ons' in the firefox menu, into the extension tab (just like before) find the adblock addon and click on the 'disable' button. NOW GO TO YOUR GAME SITE AGAIN & SEE IF ITS STILL NOT WORKING FOR YOU OR IF ITs (sorry, not yelling at you. That key placement sucks) see if its working like it did before adding adblock. If its working good without it then its that particular add0n causing the puzzle problem. This is okay, you just need to follow my instructions and get a different adblock addon from the same place you got the first. You may have to install a few (one at a rime) til you find one that doesn't block your puzzle from working. If you notice while looking for add-ons the list will contain only ones that go with your version of firefox & OpSystem. Occasionally you may see one grayed out, that means not available to your version as well. Try bthat while I finish up with my stuff. And let me know whats happening. Good Luck.
(My typing sucks but I have very long nails and well...)

Why does f12(preview in browser mode) not render the page correctly?

Why does f12(preview in browser mode) not render the page correctly? Instead when i go to the main or original file, it renders properly? It is drriving me nuts! HAHA! Can anyone help? mainly CSS problem, div overlapping but when viewing from original file on browser not through F12, it renders correctly. CS5.5 DW. Thanks!

just that one of it is a f12 (preview in browser) while the other one is going to the directory and clicking the html page by itself.
F12 is simply a hot key that launches your browser.
The only thing I can think of to explain this is that you have a local site folder someplace in addition to a testing server site.
When you hit preview, your testing server on the localhost/ is being called up in the browser.
When you open the HTML page directly, you're seeing the local site file with unparsed data.
Try disabling your Testing Server in Sites > Manage sites > Edit...

I am not seeing the URL preview you get when you hover over a link. Why?

Until today, when I hovered my cursor over a link, a preview of the link's URL would appear on the lower left of my screen, above the Start button (I use Windows Vista). Currently when I hover over a link, no preview appears, so I don't know the web address of where I'm going when I click on the link. I thought that maybe this was due to updating to Firefox 19.0, but my friends who have also updated say that they can still see the URL preview. Did I somehow turn off the URL preview by accident? If so, how can I turn it back on? If not, why is it gone?

Do you see toolbars like the Add-ons bar (Ctrl+/) or the Find bar (Ctrl+F)?
Start Firefox in <u>[[Safe Mode|Safe Mode]]</u> to check if one of the extensions (Firefox/Tools > Add-ons > Extensions) or if hardware acceleration is causing the problem (switch to the DEFAULT theme: Firefox/Tools > Add-ons > Appearance).

Why can't I resize a text box in the new Preview in Yosemite?

I just upgraded to Yosemite, and I am having trouble with the new Preview. I am a student and my notes are pdfs. I have been using Preview to take notes on the pdfs for the past two years. I have always been able to insert a text box, make it a certain size (resizing it using the text box function and dragging the corners/sides to fit the space in which I want to type), and type easily. In the new Yosemite Preview, I can insert a text box, but I can only resize it horizontally (not diagonally or vertically), and when the text reaches the right edge of my box, it moves upwards instead of continuing the text downwards (the entire box shifts up so that my typing line is in the same position as where I started and the previous text is now above). Is there any way to get around this? I really don't want to purchase software just to be able to easily add text to a pdf.

I find it annoying too. Also, when you want to add text, you always need to open the title bar and then to text box always goes in the middle of the document. The only way I found to get over that issue was to ask my friend to put Preview 7.0 on a USB key (he is still on Mavericks) and then I dragged it in my application folder. It works for some PDFs but not for all of them unfortunatelly...

Why the poor previews?
