Keynote vs Powerpoint file size

You will find Keynote Files are generally larger (sometimes much larger) than an identical PowerPoint file.

I have iWork 08. Someone sends me a pps file with 18 slides. The music doesn't work, but the file size as attachment to Mail is 1.2 mb.
I prepare a slide show on Keynote, only 15 slides, with music which I want to attach to Mail. It weighs in at 39.7 MB.
I export it to ppt where it is now 39.5 MB (and the music works)
Is it possible to produce something that you can reasonably attach to a Mail message ?
I have searched 'Help' and 'Tutorials' with no luck
Anyone point me in the right direction, please.

I take it that you're using the PowerPoint theme that the presentation brought over with it. What do the slides look like? (how complex, artwork, etc).

Thanks Kyn, The pps which came in opened with Keynote. (This is normally the case with pps unless I open Power Point first, or request it with the Ctrl key)
The picture quality was clear but not sharp in resolution. ok for its purpose, flowers and countryside, and measuring approx 18cm by 14cm. (no music although it requested sound switched ON)

Since my first note, I remembered that I had taken my pictures straight from iPhoto, so they were in original format of around 1.4 to 2.2mb each which accounts for the size (and excellent resolution) so I tried making a medium quality selecton within iphoto to Mail.
This worked ok and I found when I dragged he pictures from Mail into Keynote I could 'adjust' the picture quality , however, next problem was the frame of Keynote was much larger than the slide which was now approx 13 x 9cms, which was acceptable for my purpose.
Haven't found out yet how to fit the keynote window to the picture. The Inspector not very helpful.
Am sure there must be a neater way of doing this than via iPhoto, and there must be a simple click somewhere to match picture with frame
Open to further advice

So what's the size that you're down to now?

I have now 5 slides from iPhoto and via Mail to Keynote, no music yet, and am at 800kb. I stopped there as I did not think that the route via Mail was the way to go, and waited to see if you knew a more elegant solution. I don't think the music should be a problem.
Also, the present slide at 13 x 9 cms does not fit the keynote window, and I can't find the button to make them coincide.
I have looked at the tutorial stuff, but didn't find anything helpful - (probably my own fault, but need a couple of clues..)

Eric

The cm measurements are throwing me off a bit 😉 What are those dimensions in pixels? Some cutoff may be expected, but the ratio of your images versus the ratio of your display hardware (will you be using a projector or just displaying on your laptop/desktop screen) will determine how much.

Also, is there a specific reason why you're going from iPhoto via Mail to Keynote, you can use Export to directly create images of a given pixel size right out of iPhoto. Then drag and drop those into Keynote.

Thanks, Kyn. Sorry about the cms. This is for laptop/desktop screen and I am just getting myself familiar with Keynote creation.
You have given me enough to work on, will be back, as have something more urgent right now, but will be back later...
Eric

If the laptop/desktop is widescreen, then you'll be shooting for a 16:10 resolution and you'll likely want to make your slides the same size as your screen so that there's no resizing. This means that some of your photo is going to be cut off at the top and bottom OR if you want to use the entire image, you'll have dead space to the left and right.

Kyn, I have reconstructed my trial Keynote slide show. I now have 14 slides totalling 900kb using Export from iPhoto, time for slideshow is 1m30secs. With music.
Have changed Ruler Units in Preferences to Pixels. The Keynote window measures 85across x 50down.

Works just fine, exported it to ppt, which also works fine. BUT

Keynote version is 33.5 Mb and ppt version is 33.8 Mb. Both when started occupy whole 20" screen on my Mac. What is using all the memory ? Give me another clue. Objective is a reasonable size to attach to Mail.

Eric

85 across and 50 down? That doesn't sound quite right, Keynote presentations are usually 800x600 or 1024x768 or larger. 85x50 may be some different measurement. When you click on your images and check the inspector, what is THEIR resolution?

What theme are you using?

1 The 80 x 50 came from Keynote Preferences - Rulers. I asked for pixels but they were displayed as a percentage. Have un-clicked that and have now 720 across the top and 380 units top to bottom.

2 Inspector says 1024 x 768 for the images

3 Theme is "Gradient"

4 On the 'Navigator' window, each slide shows the actual picture occupying top left hand quarter (approx) of the slide. There is also on each slide a tiny triangle (blue) in the bottom right-hand corner which may be significant - it does not respond to a click

Hope that helps. We must be nearly there ....

Eric

If the images need to fill the screen, they don't need to be any larger than 720x380. So, exporting out of iPhoto at that res will save you even more space.

The "Gradient" theme includes a background image, one per slide. Since your images take up the entire screen, use a theme that doesn't have background images (Like white or black).

Currently images are 600 x 450, (a little less than 720 x 380).
I have changed the "Gradient" theme to Black which got me from 33.9mb to 33.7mb.

What exactly is taking up nearly 30mb of memory ? Or do you think that is about right for a Keynote (and Power Point) slide show with 15 slides - including the title ?

As I've said, it works just fine, but I could not attach it to an e-mail without causing a traffic jam.

Eric

Haven't heard from anyone, so I'm going to drop this project until I find a straightforward 'how to' text from Apple.
Just to recap. I recd. a pps file today, attached to a Mail message. It had 12 slides, photos and text, and was a whole 964 kb. I opened it in Keynote, size 720 x 520px, excellent resolution.
I saved it as Keynote document to "iWork 08" and this made the size 672kb.

My attempts to match this fail to get below about 34MB, though I managed a QT version at around 12MB. A conversion to PowerPoint (ppt and pps) got me down to 33MB.

Just tell me where to find the Manual and I'll get myself educated. I have read some of the Apple Tutorials and they are a bit thin. So I haven't found the right book.
