Blu-ray rendering
I have a project that consists of 10 MPEG2 4:3 events that are roughly 2.3 GB each when rendered in the MPEG2 DVD NTSC format, using “good” as the rendering quality. At least that’s how big each of them are when imported into DVDA5, after rendering in Pro 9c. Instead of using the DVD format, I decided to try rendering all the events in one project using the MPEG2 1440x1080i Blu-ray 25MBPS format, and put them all on one Blu-ray disc. I figured the file would be less than 25GB after rendering and would fit on a Blu-ray disc. The project rendered fine. I then imported it into DVDA5,but after loading, the file size was 89GB, which is obviously way to large for one disc. Any ideas on how the project got so big, and can it be fixed by using different project settings prior to rendering in Pro 9?

Yup… You took MPEG2 DVD NTSC formatted files that averaged about 6 MBPS and rendered them to MPEG2 1440x1080i Blu-ray at 25 MBPS. So they should be about 4x larger than they were before (25MBPS vs 6MPBS).
Do the math:
10 x 2.2GB files = 22GB x 4 = 88GB
Which is almost exactly what you got. If your intent was to place your NTSC DVD MPEG2 files onto a 25GB Blu-ray disc then do that. Don’t re-render them, just use them “as is” in your DVD Architect Blu-ray project.
