Projecting a keynote presentation
When connecting to an external projector to give a keynote presentation sometimes it works perfectly and then with other projectors all I get projected is my desktop background but no icons, and so cannot project the presentation. is there a solution or is it that some projectors are not compatable with my macbook pro ?
Hey sjohnc,
It sounds like the display is extending the display of your MacBook Pro, Check out the following article to setup mirroring or move Keynote to the other display.

Using a Macbook 2008 with Lion, 10.7.5, how can I project photos/keynote presentation on my smart tv? It is connected to tv with mini-dvi/hdmi cable, but I don't know how to display the images. Thanks!
Did you switch the TV's input to the HDMI port you are using with the computer? Did you open Displays preferences to see if a second screen is displayed and then check the box to mirror to the TV screen? Did you search Google for any help links on how to do what you are trying to do?

I would appreciate it if someone could advise me as to the optimum resolution, dimensions and dpi for actual photographic slides that I am scanning for use in a Keynote Presentation, that will be projected in a large auditorium. I realize that most projectors in auditoriums that I will be using have 1024 x 1200 pixels, and possibly 1600 x 1200. There is no reference to this issue in the Keynote Tutorial supplied by Apple, and I have never found a definitive answer to this issue online (although there may be one).
Here’s my question: When scanning my photographic slides, what setting, from 72 dpi to 300 dpi, would result in the best image quality and use up the most efficient amount of space?
Here’s what two different photo slide scanning service suppliers have told me:
Supplier No. 1 tells me that they can scan slides to a size of 1544 x 1024 pixels, at 72 dpi, which will be 763 KB, and they refer to this as low resolution (a JPEG). However, I noticed when I looked at these scanned slides, the size of the slides varied, with a maximum of 1.8 MB. This supplier says that the dpi doesn’t matter when it comes to the quality of the final digital image, that it is the dimensions that matter. They say that if they scanned a slide to a higher resolution (2048 x 3072), they would still scan it at 72 dpi.
Supplier No. 2: They tell me that in order to have a high quality image made from a photographic slide (starting with a 35 mm slide, in all cases), I need to have a “1280 pixel dimension slide, a JPEG, at 300 dpi, that is 8 MB per image.” However, this supplier also offers, on its list of services, a “Standard Resolution JPEG (4MB file/image – 3088 x 2048), as well as a “High Resolution JPEG (8 MB file/image – 3088x2048).
I will be presenting my Keynotes with my MacBook Pro, and will not have a chance to try out the presentations in advance, since the lecture location is far from my home, so that is not an option.
I do not want to use up more memory than necessary on my laptop. I also want to have the best quality image.
One more question: When scanning images myself, on my own scanner, for my Keynote presentations, would I be better off scanning them as JPEGs or TIFFs? I have been told that a TIFF is better because it is less compressed.
Any enlightenment on this subject would be appreciated.
Thank you.When it comes to Keynote, I try and start with a presentation that's 1680 x 1050 preset or something in that range. Most projectors that you'll get at a conference won't project much higher than that and if they run at a lower resolution, it's better to have the device downsize your Keynote. Anything is better than having the projector try and upsize your presentation... you work hard to make it look good, and it's mangled by some tired Epson projector.
As far as slides go, scan them in at 150 dpi or better, and make them at least the dimensions of your presentation. Keynote is really only wanting 72dpi, but I do them at 150, just in case I need to print out the presentation as a handout later, and having the pix at 150 dpi gives me a little help with their quality on a printer.
You'd probably have to drop in the 150 versions again if you output the Keynote to .pdf or Word or something, but at least you have the option.
And Gary's right (above) go ahead and scan them as TIFFs. Sooner or later you'll want to do something else with these slides (like make something for an iPad or the like) and having them as TIFFs keeps your presentation looking good.
Finally, and this is a big one, get to the location for your presentation ahead of time if you can, and plug the laptop in and see what you get. There's always connection problems. Don't let the AV bonehead tell you everything will work just fine ('... I don't have any adapters for a Mac...') . See it for yourself... you're the one that's standing up there. Unless it's your boss, then you better be really sure it works. -
Project something on the bottom of the screen DURING a Keynote presentation?
I need to be able to project something on the bottom of the screen DURING a Keynote presentation. Is that possible? At our church we have a numbering system for parents/kids and occassionaly we need to project the number so the parent can go check on their child. How can we do that during an active Keynote presentation?

Keynote presentation very blurry after exporting from imovie 08
1. export keynote presentation as Quicktime .h264 size 512x384. The exported file is a .mov and the picture quality very good.
2. Import .mov file into imovie as an event.
3. Create a new project and drag event into project
4. Share/export using quicktime
5. End result is .mov but picture quality very blurry
Any suggestions as to why the final result is so poor quality?
I have tried most combinations of file type/settings/filters.
Any help would be appreciated
jebriordanI converted it to QuickTime using the codec and frame rate you mentioned, but when I opened the converted file in FCE, the video played but there was only beeping for the audio.
I'm not sure what you meant by making my sequence settings and my media settings match, if you could give me a step by step to check that, that would be helpful. (I'm very new to this, so I don't really understand what you're talking about there.) My camera shoots in .mod format. I think iMovie then imports my .mod files and saves them as .mpeg files. Then it saves my projects as .m4v files. (That may be incorrect. That's just my guess as to why I had the movie in .m4v format, because I didn't do anything to it other than save it.)

Sides of Keynote presentation cut off when exported to iDVD
Hi,
I have a keynote presentation with the slides set to 800X600 that I am trying to burn to a DVD. I am able to burn fine but when it plays on my DVD player and CRT Samsung TV, the sides of the slides are cut off so that the first and last letters of many lines are not viewable. I also tried on a friend's TV with the same results The DVD looks fine when playing on my iMac but it's widescreen.
I first tried exporting the keynote presentation as a quicktime movie set to full quality 800X600. The next time I exported to iDVD which first exported to a quicktime movie with a size of 720X540. I thought that would fix it but that presentation also has the sides cut off. The iDVD project is using a standard 4:3 aspect ration. Should I try a widescreen project or won't that make more of the slide disappear. Any help would be much apprecitated.Your problem is that while on a monitor, you can see the entire picture. Any DVD player connected to a standard television is going to show, at most, 90% of the image...some may only show 80%. This is due to something called Overscan on televisions. To account for this overscan, you have to make sure that as you're creating your presentation, you have nothing near the edges.
A good rule of thumb is to create an area that's 80% of the size of your presentation (in 4:3 resolutions, widescreen, you only have to worry about the right and left) and, as you're creating, keep dropping this shape onto your presentation slides to make sure you're inside it. Then, you'll be pretty sure that even on the worst televisions, all you information will show. -
How can i insert a song in a keynote presentation?
How can i insert a song in a keynote presentation?
Thanks for tour help.Hmmm... I made the opening in motion, and have set it as a opening bumer. So what I typically do is drag it in to the project time line from the right side of the screen (where my bumbers are) and then add the audio (from itunes) on top of it. So that audio is being duplicated on every single event. This was the only way I knew to do it so I could easily change the date without having to always set the right keyframes. (If there is an easier way, please let me know.)
For the ending bumber I just use a small video clip I made and insert it in each timeline. So I'm assuming that is also being duplicated every single time. -
I have a 2012 MacBook Air.
What I would like to be able to do is plug into an external display and project a looping Keynote presentation on the external display. The problem is when I play the Keynote presentation, my laptop screen goes black. Is it possible to play/loop a Keynote presentation on an external display while working in a different program (Pages, Numbers, etc) on my laptop screen?

Do images imported to Keynote retain their previous color profile? In other words, if the Keynote presentation will be shown using an sRGB profile projector, should the images be converted to sRGB prior to importing or can they be batch adjusted in Keynote?
While I feel your comment doesn't directly address my question, why I am worrying is this.
This presentation is to a camera club. Color is important. Images shown in meetings are projected by an sRGB color profile projector. Most serious photographers us a color profile with a bigger space than sRGB (typically RGB1998). If you project an RGB1998 image on an sRGB projector the colors go to crap. More precisely they become dull and lifeless. Thus, I am trying to determine whether I need to convert the images I plan to put into my Keynote to sRGB and boost the saturation PRIOR to importing them or whether Keynote has a way to do this as part of the software.

Using After Effects to create dynamic keynote presentation
Hey everyone,
I am working on a project that involves adding dynamic content to a keynote presentation - short animations that must coincide with a spoken presentation that is being given.
I am unsure on what the best way is to do this..
I was thinking of creating small movie clips that live in each frame of a keynote presentation. That way the presenter could move through the slides as he spoke and the movies would match up with what he is saying, rather than making one large movie that is paused and played as he spoke.
Does anyone know of any examples of presentations that are like this? I can't find any online.
Thanks.
NealI would definitely build segments into each slide so the Presenter or operator has clean, foolproof control over each segment's playback. You don't want to be fiddling with pause controls on the day.
I'd create the movie in one AE comp, with 1 second static points at the pause locations (with absolutely nothing animated at those points) so that the pauses are seamless.
From there, it's up to you.
You can render multiple Quicktime segments as a Quicktime-per-slide for the Keynote presentation.
You can render one long Quicktime, then use Quicktime Pro (or any non-linear editor) to export each segment as a Quicktime-per-slide for the Keynote presentation.
Or, you can render one long Quicktime, place it into each slide of the Keynote presentation, and define in and out points for playback on each page using the Keynote Inspector's Quicktime tab.
I use Quicktime Animation codec at 85% quality (with keyframes) for this kind of job, and have no problem playing HD 1080 files from a 7200RPM hard drive. It is far cleaner looking than H.264 or any other MPEG variants, but small enough for reliable playback. -
Retrieving movies from keynote presentation?
I made a keynote presentation last year with embedded movies
in the slides. Is there away to use the movie in other applications or other keynote projects
since I lost the original movie?
In other words i have a movie in the slide that I want to use elsewhere
I tried a drag and drop to the desktop without success. Any Ideas?Right click or control click on the document icon and choose "Show Package Contents". You'll find your movie right there. (Another good reason to embed those movies, eh?

How do I create a switching dual screen video of my Keynote Presentation?
I have a presentation that I did where my keynote was up on the wall projection, AND I was being recorded on video. I'd like to create a web version that includes both the video of me, and the slides from my keynote presentation.
I'd like to be able to switch back and forth from the video to the keynote in the same way that Mr. Jobs does in his Keynotes, with a smooth second window gliding in to show either the keynote or the presenter, or both.
How is this done?I have never tried this, but I would think that this would be easiest in iMovie using the Picture in Picture feature.

How do you make an iMovie HD movie full screen in Keynote presentation?
Hey everybody, and Happy Holidays!
I have a presentation tomorrow morning where I will be using a VGA connector to a video projector to present my Keynote presentation. I have tried just about every way I know how to make my imported iMovie HD film full screen during the Keynote presentation, but so far the best I can do is making the slides the 1024 size, which still leaves a black background above and below the movie when it is playing.
Basically, what can I do to make my iMovie film full screen in Keynote?
Thanks!
-RandyFirst off, I'd be a bit worried if the movie wouldn't play in Quicktime Player -- that's pretty odd, since QT is essentially what Keynote is using for playback as well.
If you have a new MacBook, then its display's "native" resolution is 1280 X 800, which is pretty much HD (which is 1280 X 720). By way of working through this, I'd first set your screen to 1280 X 800, and then set the slide size in Keynote to 1280 X 720 (which is one of the default sizes, precisely because it fits HD). If you do this, and if you set your movie as wide as it will go and centred, then it will leave 40 pixels at the top and bottom of the display when you play the presentation. There is no way around this, as it is simply the case that the height of the movie in pixels is less than the height of the screen. If you tried to fit the movie onto all of the screen, you'd either have to blow it up so that the top and bottom were at the screen edge, which would cut off the left and right parts of the movie (this is like what is done in "pan-and-scan" or "full-screen" DVDs of theatre films), or you'd have to "stretch" the movie vertically, which would distort it.
Complicating all of this is your projector. Even if it is just mirroring your display, if it is a digital projector, it too has its own "native" resolution, and unlike your MacBook, it is very unlikely to be a 16:9 ratio, but rather a 4:3 ratio (800 X 600, or 1024 X 768). So even if you hook up your 1280 X 800 MacBook, the projector will still at best project a squarer image, which may show up as narrow bands of darkness above and below your "mirrored" display.
In short form: there is no way to avoid the black bands -- they arise because the movie isn't as tall as the display, and there's no way around that. -
I am making my first keynote presentation. I transferred the slides from a power point. I did not use a 'theme' from keynote. Keynote will not let me 'name' the presentation and the 'save as' option will not come up in the menu. What have I done wrong
When it comes to Keynote, I try and start with a presentation that's 1680 x 1050 preset or something in that range. Most projectors that you'll get at a conference won't project much higher than that and if they run at a lower resolution, it's better to have the device downsize your Keynote. Anything is better than having the projector try and upsize your presentation... you work hard to make it look good, and it's mangled by some tired Epson projector.

Why are .jpg files with text pixelated when projecting through Keynote?
I have a police report that I'm trying to project through Keynote as part of a larger presentation. It projects beautifully if I just mirror the screen, but for purposes of the presentation I have to use Keynote and can't switch back and forth. The text is so pixelated it's unusable and I've tried scanning at high resolution, but no luck. I'm confused about it projecting fine when not going through Keynote, so I feel like there's maybe a setting in the software I'm missing.
Any ideas?The text is so pixelated it's unusable
The resolution of the projector will be much lower than the display connected to the Mac.
Therefore, with the projector connected and powered on, open System Preferences > Displays, in the settings window for the projector, select scaled option and set to the highest pixel size listed.
I've tried scanning at high resolution, but no luck.
You have scanned a paper document?
Then scan to at least 1200 x 800 pixels, do not use a dpi or ppi setting in the scan software, use pixels, then save as a TIFF file.
I'm confused about it projecting fine when not going through Keynote, so I feel like there's maybe a setting in the software I'm missing.
Set the slide size in: Inspector > Document > Document > Slide Size; use custom from the drop down menu and enter 1280 x 800
The inspector is the side panel on the right hand side
