With the limited info provided, my recommendation would be to get a faster computer.
That would be ideal but unfortunitly not an option at the moment :-( I am not a wizz on computors and would love to know what other recommendations you have...Is there something I could do in the computor..like free up memory?...get more ram?...or change a setting?
I have Adobe Premiere Elements 10
All the recent updates.
Op Sys. Windows Vista Home Premium OEMAct Acer inc.
Type: VLC media file (.mts).
Problem happens when editing with transitions and effects, worked better with less.
What is third party effects and I/O haerdware? I only use the effects that came with the pack and content.
Dont know if I am using Mercury Playback EngineGPU Acceleration...
Problem only happens with previews and dose not effect final mixdown/output..

Thanks for the information
Premiere Element 10
Windows Vista Home Premium (it will not much matter at the moment, but is it 32 or 64 bit?.... you would still have Premiere Elements as a 32 bit application with the resource limitations of 32 bit).
So, depending on how the Q&A goes, we may need to go into the details of your computer environment and the size and duration of the files that you have on the Timeline when the problem exists.
A just in case question....after you place your video transitions and apply your effects are you seeing a red line over that content on the Timeline? If so, are you rendering that Timeline content by pressing the Enter key of the computer main so that the red line turns green?
1st, the information FAQ I posted has questions based on where you posted, which was the wrong forum... the correct list of questions is http://forums.adobe.com/thread/1042180
Type: VLC media file (.mts)
VLC does not create original files, it is a media player (which can convert files) so, what is the brand/model camera you used to create the files?
And, more information about your computer might help someone help you... CPU and amount of ram, as a start
