Is there a time limitation on Keynote exported Quicktime?

I'm trying to output a very long (3 hours) Quicktime Movie of a Keynote generated presentation.

The presentation plays fine in Keynote. I've stripped out all the .mov imbedded Quicktimes. I've recorded a voice-over track using Keynote - which establishes the 'length' of the presentation.

I 'share' and export as a Quicktime (high resolution - but at 720 X 480), and 24 fps (the only choice).

It goes through the process of generating a Quicktime. But when it is finished, there is nothing there, the folder I've assigned to receive the exported Quicktime is empty. There is no Quicktime anywhere else on the drive.

Is there a limit to how long a movie Keynote can export? Is resolution a factor?

Is there a third party app that would allow me to 'film' the presentation as it plays, that could handle the long running time?

The plan was to export the Keynote to a Quicktime H264 (the only choice), then convert the H264 to ProRes LT, bring it into FCP 7, add in the Quicktime imbeds, about 8, possibly break the long presentation into three one-hour shows, and re-exportthem out as highrez H264 for distribution as downloadable movies.

I suppose one could bring the H264 into FCP10 or iMovie and skip a process, but I'm helping a friend do this, she has 20 of them to produce, and already has FCP 7. I don't have the time to get familiar with FCP10, and it's a lot harder for her to learn FCP10 or iMovie than FCP7 (the way I would teach her).

All ears for any suggestions ...

Too weird for words. There was absolutely NOTHING in the receiving folder, I checked three times. I closed Keynote. I went to create a 'test' of only a few slides, I set the export choices, I go to export ... and there I suddenly my movie, my 3.5 hour movie, sitting in the exact folder that was empty ten minutes ago!!

Ooooeeee oooooeeeee

Keynote produced a 3.5 hour Quicktime. It plays just fine.

So my question above is redundant.

Though any suggestions about my modus operendi would be appreciated. FCP10 vs. 7 or iMovie. My brain always struggles with the logic of iMovie, struggled with the mechanics of FCP10 too. The way I'm wired perhaps.

The full compliment of QT CODECs that are installed on your Mac are available in QT export settings:

Share > Export > QuickTime:

Formats > Custom

Video Settings

in the Compression Type drop down menu; choose a FCP compatible file type and set the quality slider to an appropriate level

Allow a few minutes for the QT file to be generated after the encoding has finished, it doesn't show immediately.

Thank you thank you thank you Gary! Excuse my exuberance. I'm just helping a friend with her project, getting her up to speed on how to do it herself.

AND...

Do you know if PowerPoint has a similar ability to output a specific codec Quicktime, successfully?

I often have to shoot these very intense science conferences, and turn the presentations into Blu-Rays or DVD's. It's been a bit of a nightmare, for years. I usually shoot them with two cameras, one on the speaker, one on the screen so we can see when the slides change in relation to the talk. Then we've brought the two video files into FCP, synced them, replaced all the PowerPoint/Keynote with the original slides, and done a cut back and forth with the speaker footage. A very laborious job.

Several years ago I looked into trying to record the PowerPoint/Keynote internally as it was being advanced, but whatever I found was super processor intensive and susceptible to crashes. Nothing really worked. Too much risk.

Suddenly I can see recoring an audio track with the Keynote (to set timing) and outputting the end result as a ProRes ... wow.

Now here's a conundrum that goes with this ... what about the guys who wave a laser light at the screen in the theatre? Ooops. And sometimes that laser light is so telling in what we are supposed to be putting our attention on.

Maybe I can just encourage all the gang to make better PPT/Keynotes ... so no laser is required.

Onward, upward! Thank you again...
