Keynote Won't Play video on presentation

If Perian is installed, you will fund the icon in the "System Environment Setting Panel" (I do not know the exact English name). Clicking the icon should results in the pop-up window, where you will find the 'remove' bottom. That's it. I hope your success.

I'd like to confirm that uninstalling Perian worked for me! Great! That was easy. Here's what I did:

1. Go to System Preferences and click on the Perian icon (If you don't see this icon, that means you don't have Perian installed):



2. Click on the "Uninstall Perian" button. That's it! When I tried watching a .mov or .mp4 video clip in Keynote, it worked like a charm.

Removing Perian did solve the problem... finaly!

Still wondering, is this a Quicktime or Perian problem? I did not have any bad experiences with Perian before the QT update two days ago.

All the best,

QT7.3.0 upgrade breaks Keynote4.01
Perian (?) is not installed
I had to use Keynote 06

Apple please help

Here Tiger, Keynote 4.0.1, QuickTime 7.3, no Perian and it doesn't work. Uninstalled QuickTime completely, downloaded it (not Software update) and still it doesn't work.
A serious solution is needed.

Same problem here with Quicktime 7.3, No Perian but Keynote 4.01 will not work.....
I am using 3.02 now on my MacBook.

me too, I'm wondering if it is a Perian or a quicktime problem, under Tiger it seems to affect certain .mov formats only (sorensen, H264, jpeg-video, etc.).
I had exactly the same problems with keynote 4.0.1 on two g4 under Tiger, one with perian installed, the other without.
mp4 is working for me and my solution for the moment (even if all other external formats ar working too - wmv, divx, avi).

Had a large audience yesterday and found out immediately before the presentation that I should not mention movies. In my case, it seems that Perian was the culprit. Maybe other QT-plugins make also trouble and that deep inside it is a QT7.3-Problem.
Thanx community and good luck for those that still search other ways out of this dilemma.

Hi,

I've been trying to define the limits of the problems and possible workarounds until an update appears. The big temporary fix is to create a new user (temporarily). You can take any keynote file then and open it up in the new user and it will present properly in the new user. The smaller fix is to re-encode the video as some others have suggested. H.264, Mpeg, Avi, don't seem to work, but other codecs like H.263 do. Just to save you all some time there doesn't seem to be any other real solution but to wait for an update. I spent 4 hours at an Apple store working the problem with all the top Geniuses and Creatives. Hope that helps.

I can confirm that removing Perian fixes part of the problem, but better yet, is to leave Perian on your computer and in Keynote under Preferences/Slideshow select "Allow Exposé, Dashboard and others to use the screen".

This error (and fix) is known by the Perian team, but apparently it is a bug within Keynote rather than Quicktime and Perian. Read more on http://trac.perian.org/ticket/263

Selecting the solution above, fixed it for me.

I to can confirm that uninstalling Perian has solved my issue.

Actually, before I came on the boards, I was moving files from one keynote to another and my macbook all of a sudden shut down and restarted. Couldn't believe it. Thankfully I did not lose a lot of work, but still, I let Apple know. I'm glad to know I'm testing for Apple! Though I assume that responsibility for buying Leopard right off the bat. Haha, hope everyone finds their solution, and thank you to those figured out the Perian fix. Cheers ~

Thanks, I tested that on Tiger with a slide show and H264 .mov in it, which did the black screen before. With Perian installed but keynote prefs/slidehow "allow exposé etc. " checked, it will work normally.
A workaround which "can slow down animations on some configurations" ....

Same thing here, too. quite curious, but same software gives different results on 2 different machines: Keynote 4.0.1 and QT 7.3 work fine on MBP 10.5, whereas I get blank image when playing videos in Keynote on my mini 10.5 with the same sw configuration. no perian on both macs.
please apple give us an answer!

I confirm Tinou's trick: select in the preferences/slideshow preferences the "allow Exposé, Dashboard and others to use screen". I'm back to normal since then. (10.5, no perian ever installed).

too much honor, it's not my trick, but a workaround suggested on the perian team and posted here by themax ....
