Q: Keynote's Presenter View misses animated objects in Rehearsal mode

Current slide and Next slide are numbered the same

If you have set presenter view to show current slide and next slide,  then slides containing builds will show two views of the same slide, (not two separate slides).

As below, presenter view is showing two stages of a build sequence of a single slide,

the slide number indicates that two different views of slide 5 are being displayed,

the left preview is showing the current view, the right preview is showing what will be the next build in the sequence:

What about the second part, that is when some slides (actually quite a few of them) containing objects are shown as empty in Rehearsal Mode?

As described in my first reply, slides with builds will not show the content until they are actioned.

• the point of using builds is to show the content on a slide in a sequence, and only at a time when the user wants it to be seen
• the point of the Presenter Display is to show what the viewer sees, and to show the next event in the sequence (next build or next slide)

In the example below, the Current Slide preview shows only the white background, the text has not been actioned to display yet,

the Builds Remaining preview shows the text that will show when the build is actioned

If you don't want to show an "empty slide" to your viewers,  don't use a build on the first object, only add builds on subsequent objects.

1. I chose all the slides and builds to be fully automated, no manual building. Could this contribute to such behavior I described?

What you are seeing in Rehearse Slideshow is correct behaviour, there is nothing wrong.

You need to familiarise with what presenter screen is showing.

Presenter Screen shows the following information about each slide to the user:

1. the number of slides in the presentation and the slide number that is currently being shown
2. the content of the current slide
3. the slide number of the slide to be shown next (what is shown may be a different slide or the same slide if there are builds on the slide)
4. the content of the next slide
5. the content of the current build being shown
6. the content of the build that will show next

Could you, please, specify, what you mean by first and subsequent objects?

I am referring to objects that have a build atteched and the order they will appear on screen (as seen in the Build Order List)

shape 1 will display first, shape 2 will display second,  etc:

it repeatedly fails to upload my presentation to YouTube.

Sorry can't help with that, I have never used youtube upload.

after importing to iPhoto I got a number of empty slides where apparently animations are supposed to be but they are not.

As explained in my previous replies, an object with a build attached (as you have described here) will not show in rehearse play or exported images.   You may personally dislike it, but what you are describing is normal behaviour for Keynote.

If you post here a link to your Google Drive containing a Keynote file just with side 5, I will test can test it here.

I have downloaded and tested your Keynote file.

It behaves in every way I would expect, there are no problems or unexpected behaviour. I tested the following:

• play slideshow (I use two external 27" displays; one showing the presentation and the other showing presenter display, the order and views of presenter display are correct for the builds you have set)
• rehearse slideshow
• export to QT
• export to Image
• export to PDF
• export to PowerPoint (rehearse slideshow in PowerPoint behaves in exactly the same manner as Keynote rehearse)
• export to html

I can't test iPhoto as it is end of life and is no longer supported in the latest Mac OS, however the same result would be achieved by exporting to images using the "Create an image from each stage of builds" option. Again this works as expected.

This is a screen grab of the six Presenter Display views showing correctly the six builds in slide 5

(note the six blue circles under the current slide that indicates the build number of each build)

My conclusion is that what you expect to happen in Keynote, is not what Keynote provides.

I am perfectly happy with both how your presentation displays in Keynote, and also with the features and tools built in to Keynote to display the slideshow in Play and rehearse modes.

I used Keynote 5.3 to test your file.

There were many fonts in your presentation that I do not have, as I don't have these, they was automatically substituted, fonts used in a presentation are dependant on which fonts are installed on the Mac.

I had to change the timing on transitions and builds, some builds were set to less than a second and I could not follow what was happening.

As a guess, other differences will be caused by playing the presentation on different Mac OS X version; you are using Lion, I am using Yosemite.
