I'm running MS9 plat Pro in Vista and using external hard disc to store dowloaded files from HDR-SR12. I have found that I could not render and create a BluRay image if my time line is more than about 1 hour long with 5.1 surround audio.
So as suggested in the QA at Sony site I am splitting up the timeline into a couple of sequences e.g Testsect1 and Testsect2. If I render these separately I end up under the Render folder for each folder with Testsect1.m2v and Testsect2.m2v. (BluRay 1920 x 1080-50i 25 mbps template)
However, these files cannot be loaded on the time line.
The Sony instruction says"........Edit each section separately, render and re-import into a new project to stitch them together into a fianl audio and video stream.
Note that if under 1 hour I can render and burn a successful BluRay disc using the "Make Movie" options.
Any thoughts on how to create compatible files to enable a "stitch" on the timeline
