Progressive/intelaced Blu-ray confusion
My camcorder a Sony HDR-CX550 which is shooting HD which Vegas tells me is 1920x1080i upper field first. The I go to render it for Blu-ray & select to match input it then creates a file. If I open the file in DVDA & select tells it that I want to create a Blu-ray disk if gives me several options. Only one of these options is for progressive scan & that is for 24 frames,not 25.
Isn’t this camera shooting in Pal? & should I not be wanting the final disk to be 25 frames progressive? If so how do I achieve this?
Another reason for asking is that I also have a Blu-ray player that can play most formats & resolutions but doesn’t support 50 frames which I presume would be 25 frames interlaced.
Thanks in advance

Yes, it’s PAL.
[Paul Gregory] “& should I not be wanting the final disk to be 25 frames progressive?”
You might want it, but Blu-ray doesn’t support it.
[Paul Gregory] “If so how do I achieve this?”
You can’t because Blu-ray only supports PAL 50i, NTSC 60i, or FILM 24p. That’s it. So 24p is the only progressive format for Blu-ray.
But… it doesn’t matter. 😉
Since your camera is shooting progressive, when you render to 50i, each of the fields will contain exactly the same information so it will still look progressive. You will essentially have 25p in a 50i wrapper. It should look the same as 25p (because it is).

That’s not correct. 50 frames means 50 progressive frames. 50 FIELDS means 25 frames interlaced.
