Keynote Won't Play video on presentation

I am doing a presentation for school and I am trying to put in a .mov file into my presentation. When I play my presentation, all that I can hear is the sound of the video but not picture, the screen is just blank. I've tried different formats and different videos and nothing seems to work. I am just going to play if off my monitor that is connected to my Mac mini, I am not going to connect it to a projector or anything like that. Videos do play normally on QuickTime. Anyone know a solution of have heard of this problem before? I am using Keynote '08 and Mac OS X 10.5 Leopard.

Mac mini 1.83 Intel Core Duo, 2GB RAM, 80GB HDD, Mac OS X (10.5), PowerMac G3 Server (10.2.8), iMac Sage, iMac 333, and iBook SE 466

Hi,

I'm having the same problem here. It appeared this afternoon after upgrading to QT 7.3. Before updating, movies were playing without any trouble when in presentation mode (i.e. my MBP connected to a projector and running 10.5 and Keynote 4.0.1). After updating: black screen with audio only, unable to move to the next slide without quiting the presentation and restarting on the next slide. Tried repairing permissions and reinstalling QT with the standalone installer. I'll see the results tomorrow in the classroom.

Anyone else with the same problems ? Any idea for a solution ?

Hi,

I'm having the exact same issue as you - my video in h.264, or any video for that matter, is no longer playing back on my MacBook Pro after I installed the updates released today, which included QuickTime 7.3. This is true with both single and dual-monitor set-up. I have a big presentation tomorrow night and I've prepared everything on Keynote. Someone, please help!!

Hi,

Just to report I'm having similar problems. I downloaded three system updates today: Quictime 7.3, iTunes and an iMac fix. My colleague has also installed the first two on his Macbook this morning and appears to have no problems so this could be down to the iMac thing rather than the QT update.

Hopefully Apple will fix this soon.

Hey all,

I appeared to have fixed it!

A friend of mine whose a developer was trying to help me revert back to 7.2. However my mac wouldn't let me do this as I was unable to delete all of the components of 7.3 so it kept saying I had a newer version on the disk. (I deleted the app, support files etc but something was still there.) Anyway, as QT was then missing completely I went to the Apple site and reinstalled 7.3 from the itunes/QT page. Since doing so I've been able to play the files in keynote so think the update was missing some components which the download page has.

Same thing here. I have a presentation today and I'm not happy. No time to wait for apple to fix this. The solution for now is to open the movie from the keynote presentation (copy/paste into quicktime) and export it (i've only tested h.264, no time for more). Of course one needs quicktime pro for that.
not happy at all.

I did everything, but did not succeed in full-screen presentation of Keynote files containing videos. Now I have a serious problem, since I have to give a lecture tomorrow morning. If there is no urgent update from Apple to fix this bug, I would have to cancel my lecture. What can Apple do for this big problem? I am quite unhappy. I have to say that Keynote is not a business software yet.

It's not a keynote but a quicktime issue, I also tried to reinstall the file loaded from apple, but it don't work for me.
This afternoon i was forced to do my lecture without videos, fortunately there weren't more than two illustrating and no vital videos 😉

Nevertheless I hope they'll fix it quickly since I have to do others this week. Or at least the give a hint how to downgrade to quicktime 7.2

I am having the same problems. Very frustrating, as I have a presentation to give on Thursday. I've converted the movies I need to use to WMV, which works, but I lose a little quality by doing that. Hopefully a fix will come out soon for this. Worked fine, installed the QT update, and it's now broken. Can't get any .mov files to play. Same thing: just sound, no video, no response from presentation.
