Thanks for this. Here are the answers to those questions. Any help you can give me would be much appreciated.
Premier Pro CC 7.0.1
2x 2.26 GHz Quad-Core Intel xeon and 16 gb Ram
The source footage Is Quicktime Mpeg-4 (I'm shooting on a Gopro in Protune)
Im not sure when the rendering problem showed up but I noticed recently that when I go back into my Premiere project the next day i have to rerender everything. This was not happening when I first started using premiere a couple of months ago. I am not getting error messages.
The beachballing, started to happen around the same time as the render problem. The beachballing doesnt send an error message but I am forced to force quit after 10 minutes or so(when I realise that its not gonna stop)
I am not actively running other software on this computer but I do have other programs installed. The heavy hitting programs are Adobe suite (photoghop, Speedgrade, after effects, Lightroom, etc), Final Cut pro, Aperature.
No third party effects installed
Not sure if im using mercury playback engine... How would I know this?
This is a bug that sometimes occurs for a few users. The theory going around is that certain third-party effects and transitions can cause this behavior, though which ones specifically aren't known. I've seen one report of this happening with Warp Stabilizer as well, though in my own tests, it works fine, so it's not 100% the cause.
