I have only little experience with Blu-ray burning.
I want to make the best possible quality from tape (raw material) to Blu-ray.
Tape is shot with Sony HDR-HC9 in HDV 1440x1080 60i.
Would be grateful for suggestions from you guys with more experience than me.
Rather than using your video directly from your camcorder, I'd recommend you bring the video into Vegas first and then export from Vegas as BluRay-ready video. Then you'll know you're using the best possible format for DVD Architect.
Also, I noticed that Architect isn't recognizing that I have a blank blu-ray disc in the drive...it's reading as it is a normal DVD. I know I'm missing something here.
I presume this means either one can be used for blu-ray use, but I'm not really sure if there are any subtle differences. The main different I can see is on the audio side, where the 'blu-ray' template provides none so you can render your audio separately any way you want later, whereas the 'avchd' template spits out audio in this format:
Audio: 192 Kbps, 48,000 Hz, 24 Bit, Stereo, AC3
The 'avchd' choice puts video and audio both into a single .m2ts file. The 'bluray' template spits out only video in a .avc file.
