The situation with Blu Ray and 25p is the same as with DVD and 25p. If you shoot and edit 25p properly, the 25p cadence will be preserved even though the file on the disc is 50i.

OK heres one, how do you get the 25p cadance from 50i footage? If I render out as interlaced then the prepared blu-ray has that interlaced look. But I can go down to 24p and it looks nice but the workflow is a pig.

Seems to me they've not thought it through properly and have totally disregarded all the areas in the world that shoot 25P as a matter of course (the legacy of PAL systems) for video - they only seem to be thinking about film.

Well... the BluRay Disc Assocation has the following Board of Directors:

# Apple Inc.
# Dell Inc.
# Hewlett-Packard
# Hitachi, Ltd.
# Intel Corporation
# LG Electronics
# Mitsubishi Electric
# Panasonic Corporation
# Pioneer Corporation
# Royal Philips Electronics
# Samsung Electronics
# Sharp Corporation
# Sony Corporation
# Sun Microsystems
# TDK Corporation
# Thomson SA
# 20th Century Fox
# Walt Disney Motion Pictures Group
# Warner Bros. Entertainmen


Which one of these do you think was unfamiliar with the areas of the world that use 25p? And which do you feel might not have "thought through" what you have?

I'd be willing to bet my yearly salary that 25p was well discussed prior to ratification of the standards being released, and since the profits from 25p countries could equate to billions of dollars of revenue, I am quite sure it was "thought through". The conclusions they reached may not mesh with yours though, which is understandable.

As to them thinking only of film, it would seem to me that a great proportion of these BOD are not directly involved in the film industry, so I highly doubt that is true.

So you would think from that, Sony at least would 24P on the camera as well as 25P if you can't use 25P on HD discs. Duh!
