Re: I have Adobe Elements 9 and I used to be able to export HD 1080p videos with no issue. But recently, when I export using H.264 MPEG or MPEG 2, which I normally used, the high resolution videos come out very choppy.  How can i fix this?

I have been using the same computer.  No changes have been made to my graphics drive.  I've been using a Sony VAIO.  I don't think I have the latest versions of Quicktime and don't have 9.0.1.  Where can I get these updates from?  All my export sizes have been the same.  Even if I export 5 seconds worth, it still appears choppy.  I am using Windows media player for playback.  But even if I just upload on youtube, it's still choppy.  So it's not the playback media. 

Also, do you know where I can get or buy more font options for Adobe premiere?
