ultimate question for 24p effect with Z1: CF25, CF24 or Nattress? at DVinfo.net

Gustavo Godinho · September 11th, 2007, 10:26 PM

A long time since the first discussions about this issue. Now that a lot of experiences were made, it's time to decide what is the best method to achieve 24p effect with the Z1 . I can think of 3 basic possibilities, considering the final output material NTSC DVD:

A) shoot using cineframe24:
pro: needs no render.
con: jerky movement

B) shoot using PAL cineframe25 and convert to NTSC
pro: CF25 is smoother and much better than CF24
con: takes a long time to render PAL to NTSC conversion
questions:
. what's the resolution lost with the PAL to NTSC conversion, considering Nattress conversion, one of the best low budget options?
. the conversion changes the quality of the original CF25 movement, right?

C) shoot 60i, no cineframe, and convert to 24p with nattress
pro: full resolution original footage
cons: needs to render; no 24p effect while shooting and watching dailies

so, which one wins in terms of

1) RESOLUTION
2) QUALITY OF MOVEMENT

For resolution and quality of movement, actually the best option would be de-interlacing 50i footage and then slowing down to 24p, as smart de-interlacing (with Nattress Effects or whatever) would maintain resolution where ever possible (in static, high detail areas).

It's the slowest process with the mst stages though (ie slowing down AND de-interlacing)
