Re: Cineframe 30/Cineframe 25 resolution loss vs. 60i

"So what I'm saying is, CF25 is BETTER than shooting 50i and de-interlacing, because 50i->de-interlace will give you about 400 lines of resolution, whereas shooting CF25 gives what appear to be 540 to 575 lines."

I strongly disagree. A well designed software deinterlacer will, for static images and static objects deliver all 810-lines of effective V rez. Only moving objects will suffer a loss in rez. And, since the object is moving and subject to motion blur -- you'll not notice the loss in V rez!

Thus shooting interlace is far better than CF25.

While 1080i50 is a simple way to handle video -- handling audio is a nightmare.

If one is in the USA, then shooting 1080i60 is best. The software to deinterlace and generate 24fps is cheap ($100) and once in 24fps it's trival to edit video AND audio in sync.

There are dozens of 35mm films shot with 60i starting with Frank Zapas' "200 motels." All DV, Beta SP, films shot in the USA have been done with 60i. Think Hoop Dreams, Timecode, Julian Donkey Boy, etc.

The only reason PAL was popular was the extra rez. That's not an issue in HD. Plus, the horrible 50Hz refresh rate makes using any 50Hz format totally dated. Plus, try to find a 1080i50 HDTV. I read the Euro mags and they are, if you consider Japan, nearly 20 years behind the NTSC world.

And if you do find an HD panel or projector, they also display 720p60 and 1080i60.

I find it vrey odd that anyone in Region 50 would be recommending going that way. I'm in India and all the TVs show both PAL and NTSC. Moreover, Region 50 products usually cost more. Makes no sense to me. :)
