Hi Vlada,
I have the same problem.
I have also a PC running Vista 64 bit with 8G RAM and 3.3 GHz Quad Core. As disk drive I am using a 1TB raid 0 drive for the projects and media cache. So speed and memory shouldn’t be the root cause…
After some investigations it looks like error doesn’t happen when I remove all video effects like auto color adjust etc. But when I add a single effect – whatever it is – transcoding fails.
Another interesting effect is that when I close PremierePro and Encore 3 prosesses are left: PPrHeadless.exe, processorcoordinatorserver.exe and PhotoshopServer.exe.
When I manualy stop all and start Encore again the processes are restarted and transcoding works for shorter sequences (below 30 min) without removing the effects…
After successful transcoding of video Encore creates 2 files in source/transcodes folder with extension ‘.m2v’ and ‘m2v.xmpses’. Too me it looks like at least one of these files cannot be created and this generates the error. I would like to know what the dependency is between transcoding and image buffer creation.
I have posted a case to Adobe technical support. Hope they have an idea too.
Btw. I am using a German version so it is not a language issue 🙂
