Keynote 2 crashes when exporting using H.264
Posted by | Posted in Bugs | Posted on 04-30-2005
One user on Apple’s forums has discovered problems when trying to export a presentation using the new H.264 codec in QuickTime 7. If you use the custom QuickTime export functions in Keynote and choose H.264 as the codec, Keynote will crash on export. While we’re not sure if this happens under Panther using QuickTime 7 (we assume it does) we’ve been able to reproduce it in Tiger.
The fix is to UNCHECK the box labeled “Key frame every _ frames.” Doing this allows Keynote to export the movie properly. Hopefully Apple will have a fix for this soon.
Just to add my two cents, for smaller file size and better quality (or reasonable), I would suggest exporting with Sorenson Video 3 (default) for better compatibility.
Actually, H.264 is amazing. I’d bet it ends up looking better than Sorenson 3, with a smaller file.
Yes, H.264 is QUITE good. I can get similar quality to a Sorenson movie and half the file size. And that’s even before trying the dual pass option.
FYI, I’m running Panther with QT 7 installed. I just had the same problem exporting to H.264. Your tip worked. Thank you!
Thanks for the workaround!
Since I have upgraded to Tiger and Keynote 2, I have troubles exporting Quicktime and Flash. Flash-Exports are horrible > pictures shattered, texts with awesome letters. Quicktime exports are in most cases even not possible > everything seems to run ok, but in the end I get an quite ennoying error saying: “There is not enough space on your disk or there was a problem with your file”. Any hints?
Wow. Thank you so much. I was starting to get into trouble… you know big, job, deadline looming, unable to export at uncompressed because the file would be 23GB! And knowing what a beautiful codec H264 is I decided to go down that path…
I have been trying to export for 6 days… and had no idea it would be the codec chosen. As I said elsewhere, QuickTime is an architecture that every application plugs in and hands work over to…
You would think that if I was having problems with H264 it would show up elsewhere.
So, thanks to the genius who worked this out, and thanks also to Kyn Drake at the Apple – Discussions – Keynote site for being kind enough to point me this way!
A very happy lad indeed,

ps. Sorenson 3 is a technology that is 5 years old now. In digital media terms, that is ANCIENT. Don’t get me wrong, I was a huge advice fan Sorenson in their day… when developed in 1999/2000, the days of QuickTime 5.0.
In its day it blew my socks off and I thought we could never do better…
Well, H.264 is not one but two GENERATIONS of technology later… and an revolutionary breakthrough at that. — If you are still using Sorenson, take my advice, and give H.264 a whirl… do some side by side export comparisons, and I promise it will KNOCK YOUR SOCKS OFF TOO for quality, and then when you see the file size, you will laugh until you cry, as the file is only a quarter of the size you were expecting.
It is THAT good. Thanks again good folks!
p.p.s. As I did not navigate to this page, but rather was handed a link, where am I? How did I get here? May I suggest that you put a link to this page on your Support / Bugs section. Just a suggestion. Thanks, this site rocks!
thankyou, thankyou, saved my life
Money!!! I join the list of very happy production artists that have been saved “the axe” by impressing friends family and clients with a sweet H264 quicktime that is keyframe-less
Thanks for the workaround.

I had the same problem at exporting to Quicktime : “There is not enough space on your disk or there was a problem with your file”
This problem appears only in slides containing video and other objects.
After a few tries I have found the solution : if you end an object (title, image…) then video AT THE SAME TIME, then you have the problem.
Now I end video at least 0.1 second AFTER an object and exporting goes fine.

That didn’t work for me. However this solution did the trick:

Peter Dominic Ryan: If you have enough disk space, why not export as uncompressed, then use QuickTime Pro to do the compression? Might that get around what seems to be a Keynote/H.264 interaction?
Hello there,
I am trying to export my KN presentation using the H.264 option but the size ends up being 6x bigger than if I simply use the Sorenson 3 codec.
Can someone please help?
Thanks
Harj,
What settings are you using for your H.264 encode? If you’re not setting a bitrate, then it’s probably why your file’s so large.
