Actual resolution of Keynote?

I'm new to Keynote and haven't been able to find any info about the resolution, i.e. dpi, of background, images, etc IN the program. I see that I can choose 800X600 or 1024X768 as dimensions, but are all its parts 72dpi?
Since I can't find a way to choose the resolution, I assume it has one default designation. Appreciate enlightenment. Thx.

While the other comments are correct, I think the question is more concerned with what dpi the system defaults to for images, which is usually 72dpi.
However, most of the modern Apple apps ignore the resolution setting of the image. Keynote will always try to bring images in at a pixel ratio of 1:1. If the picture is larger than the screen, it will scale the image to make sure that either width or height matches the screen resolution.
Most traditional page layout programs (e.g. InDesign) do respect the image resolution, so a 800x600 image at 300dpi will import much smaller (about 2 inches high) than an 800x600 image at 72 dpi (about 8 inches high).
One of my biggest gripes with PowerPoint (as opposed to Keynote) is that at it's guts, it's works more like a 'print' program than a 'display' program. PowerPoint specifies the 'size' of the presentation in inches, not pixels. Most people ignore the setting, as they scale the presentation up/down as needed. But one of the side effects is that how big images appear when they are imported changes based on their resolution, so the 800x600 image at 300dpi will import very small, and need to be scaled up.

Printing - prints at actual resolution

TIA - Whilst printing to HP deskjet 840c or Epson640 after several docukments, random numbers on either printer, printers will start printing at actual resolution generated by print engine. eg 3 lines fill page with 8 - 10 characters to page.
only way to reset is to either
1/ clear cue
2/ reset entire printer system and reload printers
3/ restart
Logout and login does not cure.
Have loaded drivers from various sites and cleanedthem out and used defualts, no difference.
Any help usefull- apoligies for length of question.

You can specify the printing process in the PDF for Acrobat and Reader, open the PDF in Acrobat > file properties (right mouse click on the page) and in the extended tab (the most right tab) you can set printing not to scale for that PDF as default setting.

Can you change image output resolution in Keynote?

Is there a trick? I know it's nowhere obvious, but I find it'd be helpful -- I find Keynote the simplest way to create basic illustrations, but I need them at 150 DPI for printing. Obviously I could create a giant documents and manually dowsize, but I"d prefer to do it "native"...

Keynote is a video display screen presentation application and therefore the resolution is set in pixels.
To change resolution, use the inspector > documents tab and test what resolution you need for the individual printer you will be using at a particular print size.
Incidentally, 150 dpi (dots per inch) is too low to print, 600 dpi is considered low res draft, 1200 medium and 2600 high (photo quality. Perhaps you mean 150 ppi (pixels per inch) which is still low quality.

Podcast episode resolution from keynote to GB

I'm importing Keynote presentations in to Garageband to save them as enhanced podcasts for students to view my class presentation when they've been absent.
I began exporting my keynote presentations as image files, then entering them one by one in Garageband as episodes to view the presentation on a Nano.
The image on the Nano is square-ish and cuts off the sides of the slides.
At what point in this process do I adjust the resolution so these slides so they work on the Nano and to what resolution do I change them to?
Any ideas?

Adjust the resolution of your images to 176 x 132 before importing them into Garageband. To prevent distortion, first create a blank image of this size: then open one of your images, and adjust its size so that the height is 132 and the width is in proportion. Copy: paste into the blank image and adjust so that the width is cropped as you want.

Poor resolution for Keynote .mov file

Hello,
Just getting started with Keynote. I'm putting together courseware and will be using Keynote to support the presentation. I have several .mov clips I need to integrate into the presentation. I embedded a .mov file into a Keynote slide and then saved and exported the Keynote file by SHARE > EXPORT > Formats: Web Movie, Small.
While I'm getting the media to work, the resolution of the Keynote .mov file is very grainy.
Are there some settings to be aware of to get a clear resolution with a Keynote .mov file?
Thanks for sharing your insights.

You've probably picked the lowest settings and therefor the lowest resolution!
If you go to the export menu and chose a higher setting or even tinker the custom settings to get the balance of file size / quality you want.
It may also be worth making the slide size smaller (in the inspector)so when you export it's not being downsized in the same way if you need a smaller video (height, width, not file size)

Screen resolution problems - Keynote to iMovie HD to Quicktime to DVD

I'm not getting quality screen resolution when exporting slides with builds from Keynote, to Quicktime, import to iMovie, then back to Quicktime.
I notice it mainly with the text content because it's very pixelated.
The final Quicktime movie will be burned to DVD and then viewed on other's computer screens, which of course I realize will all be different.
How can I best trouble shoot this problem?

Is it possible to show actual time in Keynote?

Within a table cell I can use the formula NOW() (NU in Swedish) and get the time. But it's not updating.
The clock, visible for the presenter, would be nice to put into the presentation,
or the type of timer widget there is in iWeb.
Any solution?

Go to my public folder and download clock_from_system_time.qtz.zip. Double click to unzip, drag on to your Keynote slide, go to Inpector>Quicktime tab and set to loop. If you have Quartz Composer added to your computer, you can open it in there and change color and font. If you don't QC, let me know font, size and color and I can adjust it for you.

How can you save keynote slides as high resolution (300 dpi) images?

Apparently there is a way to save powerpoint slides as 300 dpi images, with some finagling, but not the mac version. Does anyone know how to do this in keynote? Or is there a relativley easy way to do it with free/cheap software? I can increase the dpi in photoshop, but it doesn't produce crisp images for obvious reasons.

how can you save keynote slides as high resolution (300 dpi)
to save individual images from each slide in Keynote;     file > export > images > TIFF (for optimum quality)
You are using the wrong terminology to describe creating an image file
- dpi ( meaning dots per inch ) is the measurement used in printing to create the number of print dots per inch that will be deposited on to physical media like paper or film   This is done in the printer settings box of the print driver and is dependant on how the individual printer can print..
ppi ( meaning pixels per inch ) is the measurement you need to use when creating the number of pixels in a digital image file. You establish image resolution in Keynote using the inspector;
Keynote > inspector > document > slide size
I can increase the dpi in photoshop, but it doesn't produce crisp images for obvious reasons.
You can resample images in editing applications such as Photoshop or Painter but what you are doing is adding non image information to the image to increase pixel count, this is called noise. As you state this is not the procedure to use in your situation.

Problem with HDMI - external display resolution (MacBook andSamsung HDTV)

I just bought a new MacBook, and I have used my Samsung HDTV (http://www.amazon.com/Samsung-LN-S2338W-widescreen-720p-HDTV/dp/B000G6300U) with my old MacBook for over a year. First I tried to connect the two using the Mini Display Port to VGA adapter, which wasn't recognized by the Samsung. Now i tried using the Mini Display Port-->DVI-->HDMI route. The problem I have is that, while all the resolutions show up as able to be used in the display preferences (all the way up to 1920 x 1080), when I click on any resolution for the Samsung that is over 1280x960, all windows and dialogue boxes displayed on the samsung screen are jumpy, shaky and hazy. Is there anything I can do to allow me to use my preferred resolution of 1600x900?

I'm no expert on this, but seeing as your TV has an actual resolution of 1280x720 (according to the link), I can't see how you'd get good results from anything higher than that.

Is there a way to change the true resolution rather than scaling?

Hi,
I have searched through just about every single forum, website and search engine there is and haven't found anything. Perhaps I am phrasing my question wrong. I currently own a Macbook Pro 13.3'' Retina (Of Mid-2014 since I just bought it?) and I can't figure out how to change the resolution. The OS seems to default to 2560x1600 no matter what I set it to because I think all its changing is the scaling. Is there a way to do this? I used to own a Macbook Air 13.3'' which ran 1440x900 and I know that it was pixelated. On the same size display here...when I run the claimed "1440x900" its still ultra sharp which means its using scaling I assume. Any ideas how do I change the actual resolution, not just the scaling. The OSX settings currently seem to be just the equivalent of modifying the DPI like you can in Windows. I want to find out if there is a way to change the actual output resolution.

The MacBook Pro like all laptops has an LCD screen. Like all LCD screens the screen has a single physical resolution, in the case of your MacBook Pro Retina 13.3" it is 2560x1600 pixels. This is the number is dots the screen is physically made of.
In the old days when desktop computers used CRT (Cathode Ray Tube) displays which looked like TVs these sort of displays could display multiple resolutions in fact CRTs have no single fixed physical resolution. However LCDs which use totally different technology do only have a single 'real' resolution.
If your really interested in how a CRT can do different resolutions then the answer is that a CRT uses an electron beam to excite the phosphor display on the front of the display (to make it glow), it scans from left to right, moves down a line and then does the next line, and so on till it reaches the bottom and then goes back to the top. The speed (rate) at which it does this is known as the horizontal frequency and the vertical (refresh) frequency or rate. If the horizontal line is drawn specific time and that is divided in to 640 units, then it can be told to turn off and on 640 times per line, if the same line is drawn in the same time but the interval is divided in to 1024 then it can 'draw' 1024 horizontal pixels instead of 640 horizontal pixels. In actuality the display has no physical pixel you are merely lighting up small or larger areas on the screen and hence a CRT has no single fixed resolution.
In order for a computer using an LCD display to use a different apparent resolution it has to 'scale' the image to a different size, as a very simple example if we wanted to scale down to 1280x800 pixels which is exactly half 2560x1600 then the computer would use 2x2 (four) physical pixels to represent a single scaled pixel. Often however the chosen scaled resolution may not be an exact multiple like that example. Apple on the Retina display have provided some suggested scaled resolutions which work reasonably well these being 1680 by 1050, 1440 by 900, and 1024 by 640 pixels.
None of these will look as good as 2560x1600 because the screen physically is made up of 2560x1600 dots and no amount of cheating will change that.

How to delete a file in Keynote Remote for iPhone4?

I also cannot connect my Iphone to Keynote anymore because of this file.

The file is actually in the Keynote app and not the Keynote remote app for iPhone.

Satellite Pro P300: external resolution 1024x768 instead of 1680x1050

Hi,
I run my Sat P300 on XP, and the screen on this laptop is just fine (1440x900 pixels on radeon HD 3650).
Now I want to connect the laptop to an external flatscreen monitor, a Samsung, that asks for a optimal resolution of 1680x1050 pixels.
The samsung monitor works fine on my older laptop: I close the lid of the laptop,and the screen switches to the Samsung with the correct 1680x1050 resolution.
Now, when I connect the P300 and close the lid, the screen switches to the Samsung, but the actual resolution on the monitor is 1024x768, despite the fact that the 1680x1050 setting is set in the screen properties windows.
In fact, the screen probably is 1680x1050, but the monitor only sees 1024x768 (i.e. the desktop is bigger than the monitor can show, and I can push the desktop left/right or up/down with the mouse.
So it appears (hey, this is just a guess) that the radeon sends a 1680x1050 screen with the wrong frequency (48.2 KHz instead of 64,4 KHz as my monitor shows) !?
The Samsung drivers are installed, and I updated the BIOS to 3.40 win, but no solution.
Anyone an idea ?

Hi
I posted my assumption in other thread but I would like to post it here too.
If you are not able to choose your favorite resolution on external monitor then this two reasons might be responsible for that:
1 the graphic card driver does not contain and does not support this resolution
2 the graphic card chip does not support the external resolution
In both cases the resolution will be not listed in the settings!
However, Lars posted a useful information which can be found in the user manual and you can see that your favorite resolution is not listed.

Custom book export resolution problem in PDF - only 150DPI!?

I've been using the custom book option and when it came to exporting my PDF I have run into a problem involving the undocumented output resolution of a PDF at a given size. The custom book dialog allows you to create a book with a certain size in inches, but this really has no real meaning since the resolution of that output cannot also be specified in either the layout option or the print dialog. For example is it 150dpi or 300dpi? From some investigation it appears to be locked at 150DPI.
Now I would have thought that Aperture was intelligent enough to just treat the album layout (this is my assumption) as some kind of smart object, where the layout is resolution independent and the final output resolution can be determined when printing to a printer or PDF. In that case the dialog for the setup of the custom size is correct. However, there is no option that I can see in the print dialog to actually specify the output resolution; Aperture is left to its own devices to specify an output resolution, which is undocumented.
I use a printer that accepts JPG or TIF files and I need 300dpi for an album size of 10x13 inches. This equates to 3900x3000 pixels per page. I am able to export to PDF in the print dialog and then used an automator action to export each page of the PDF as JPG and reimported back into Aperture 2 in the same action. In the PDF>JPG conversion option there is the ability to set the DPI to 300. That works fine and the resulting JPG images show as 300dpi (3900x3000px). When looking at the images though they look a little soft, which leads me to believe that my action was simply interpolating a 150dpi image in the PDF into 300dpi.
So to test this, I noticed that if I exported just one page of the album as a PDF and opened the PDF in Preview it does indeed tell you that it is 13x10 inches (no mention of the pixel resolution though). So, you can actually reimport a single page PDF into Aperture and if you do this it appears that the actual resolution is 1950x1500 and that equates to 150dpi for a 13x10 inch layout.
So there are two things that could possibly be going on here:
1. The actual layout of the album is locked at 150DPI and the save to PDF simply takes that and exports a PDF at that resolution.
2. The layout of the album is resolution independent, the size of the album (in the custom dialog) simply controls the aspect of the page layout, and the print dialog (save to PDF) is exporting as 150DPI as default. When I run my automator action (these are the Leopard PDF actions), the save each page to JPG action is up-res'ing the image to 300dpi.
This is where I need help. Is 1 or 2 (or something else?) happening. Also, does the PDF save as JPG12? That too is undocumented.
If number 1 is happening I may have to set my album size to 26x20inches to get a 10x13 inch page at 300dpi.
If number 2 is happening I need to find a PDF/TIFF/JPEG print driver to enable me to export at 300dpi as the print dialog in not standard (and we don't get the nice 'save as' drop down where we could do other things. So far my search has led me to CUPS-PDF, but that still doesn't allow for resolution to be set: http://www.codepoetry.net/projects/cups-pdf-for-mosx
Why can't Apple just figure this thing out correctly and allow the resolution to be specified by the user - what an oversight given all of the feedback requests for the custom album tool. We need 300dpi as a minimum as we can always down-res if we want.
Any ideas? I've got albums to send to clients! Help!
Thanks

When you import any PDF into Aperture, I think it rasterizes any PDF you import to a 150dpi flat image on import, even if it was a high res PDF to begin with. But theres the thing, PDFs don't have dpi (as such). Any shapes or text is a vector so don't have a DPI as they'll scale when printed. The images use their DPI when they were imported from the program that created the PDF.
So I did a quick test and put a page I made from Aperture in to Acrobat and ran a preflight check on all images to check the resolution. It came back at 349.956 ppi, so this example was over 350dpi.

What Print Resolution for Epson R800?

I wonder what the value for "Print Resolution" in the Printer module should be to print with an Epson R800 on glossy or luster paper at the highest quality settings (Photo RPM).
I would rather not have LR do any re-sampling... but given it asks for a resolution, I am unsure what is the best value to provide.

Antonio,
LR is limited to 480 dpi, not printer ppi:
"This number of ink drops a printer can put on paper is called the printer resolution dpi. So if a printer has a resolution of 1200 dpi but requires 16 drops of ink to display a color, the actual resolution is much lower. Since ink drops are used in both directions (length and width: 16 drops made up of 4 rows of 4 drops), you could say that the effective resolution would be 1200 divided by 4 (or 300) dpi. Practically this isn't entirely true since modern inkjet printer can spray tiny ink drops that overlap each other. Roughly you can say that the higher the printer dpi, the higher the print quality, but it also depends on how the printer forms the dots on paper."

Resolution Limitations with Second Display

What´s the maximum video resolution macbook MB403 can drive?
I´m using a second display (Samsung wide screen syncMaster 226BW, and after configuring it at 1680x1050 - which is the usual resolution for this type of display, I realized that the actual resolution was not greater of 1280x800, although the video configuration set indicated and normaly accepted the 1680x1050 as the second display resolution.
Is there a configuration setting I have forgotten?
It seems that 1280x800 is the higher resolution accepted by macbook own display. Is there any relation or limitation related with a second display?
Thanks.

So does anyone have experience with the Envision 22" LCD display (G2219w1)?
It works well with my 5-year-old PowerMac G4 BUT with the MacBook the whites and grays are tinged with color and the overall colors are overly saturated. Moreover, the pictures are grainy and text is muddy. I can't seem to find a good match of resolution after trying several combinations. It's reasonably sharp at 1680x1050 but the image is quite small (about 3" border on all sides which is pretty much the same size as the MacBook).
Is there anything I can do? I've tried lots of adjustments on the LCD and in the display configuration on the MacBook.
