Apple Keynote limitations - 30 seconds and stop?

rcdncn's picture

I've been trawling through the archives, and can't find a unified resource regarding QC integration with Keynote.

I've read about the limitation with unsafe patches.

I've also know that Keynote won't pass keyboard input, even for keypresses that aren't used by the program itself.

What's stumping me is a 30s limitation for playback. I've built a qlitch timer that uses System Time as a source variable, but after 30 seconds it simply stops.

If I select for the qtz file to loop in Keynote, it will, but that also restarts the timer.

Any thoughts?

Rob.

Open QC in 32-bit mode, go to "File / Export as QuickTime Movie..." and specify the desired duration there, then import the QuickTime Movie in Keynote instead of the raw QTZ file.

I was hoping to use qtz for 2 reasons:

1) small file size 2) ability to sneak/add time to the clock via external input

So, I've moved the project to vDMX for the time being, which allows me to update the base time, AND not be restricted by unpleasant, undocumented Keynote restrictions.

When you "Export as QuickTime Movie..." from QC, it doesn't actually render the composition, it just takes the composition and adds a QuickTime wrapper around it. It is still rendered in realtime by the QC engine.

Send Keynote team some feedback too. I've sent a lot of feature requests for better QC adoption at various functional points in the KN app. I also asked the QC team to make themselves known and helpful to KN team which they did. We can only hope that Keynote team take a hint one day! I'm sure they have lots of suggestions to go in other directions too.

Keynote with logic control, strong QC integration and even some sort of public API would make a kick-arse prototyping/rapid visualisation toolset.

Already it gets used for iOS app mock ups quite a bit using simple button links.

Hi steve, I was wondering how far you got when you discovered the hidden API in Keynote. Did you see enough to consider providing some tools to allow us to extend Keynote functionality in any way.

QC templates as 'builds' or 'transitions' perhaps? Passing values to QC compositions in Keynote via published inputs maybe?!

I'd consider developing content for KN if there was some way to move beyond simple themes into basic motion controlled functions (with or without QC comps).

Terrific!

This is a weird, but effective workaround. Why is this? Or should I just be happy it's possible...

Still doesn't give me control over the display time while it's live on the screen, but I'll likely create a series of wrapped qtz's at specific time increments in order to fake time changes.

Thanks, Rob.
