I guess the question is what is the best video file to export from Premiere Pro and to import as a timeline to Encore?
I captured HDV files as mpeg files in PR.
After editing, I exported the same file type to be imported into Encore.
I put about 2 hours of mpeg files into my Encore project and started the build.
After an hour of 70% cpu usage of the 4 i7 processers I saw only a third of the progress needed to convert the first hour long file.
It looked like it would take about 6 hours to build the Blu Ray DVD.
Is that the way it is supposed to work?
