1920x1080 30p (29.97)

New Vegas Studio Plat 10 + DVDA Studio user here.

Why no 1920x1080 30p blu ray project setting in DVDA? Is there a way to add it?

Vegas was also lacking this but I could go into the project properties afterwards and change it to a 29.97 fps progressive project.

If I can't do a 29.97fps progressive bluray then I guess 60i will have to do. My TV should deinterlace it anyway. Hope there is no quality loss.

The Blu-Ray official specification does not provide for 1920x1080-30p. Here is what it does support. It has nothing to do with the software.

High-definition video may be stored on BD-ROMs with up to 1920×1080 pixel resolution at up to 59.94 fields per second, if interlaced. Alternatively, progressive scan can go up to 1920×1080 pixel resolution at 24 frames per second, or up to 1280x720 at up to 59.94 frames per second:[56]

Here is the "White paper, Blu-ray Disc Format, 2.B Audio Visual Application Format Specifications for BD-ROM"

Thanks musicvid!

I should have though of that possibility.

So after doing a little more research, I should indeed be using the 60i project setting if I have 30p source video. The output on the TV will be the same.

If you shoot 30i (29.97) instead, I believe it should transfer field-for-field to Blu-Ray 60i with no loss. Essentially two names for the same thing.

My camera only films progressive so I can't do 30i.

I've read that LCD and plasma HDTVs, because they are progressive, take a 60i signal and combine every ODD/EVEN interlaced frame pair and combine them into a single frame so you end up being displayed as 30 fps progressive anyway. So even if the authoring software splits my video into 60i, it should recombine into 30p on the TV.
