I’ve been toying with the idea of creating a hybrid transfer from the Star Wars DVD/HDTV stock, one that exploits the (usually) better picture of the PAL format, but maintains the correct running time and audio pitch of the NTSC format.
Let me set this up and then I will pose a query primarily aimed at NTSC users who already own 16:9 TVs. The following material is uncompressed data from the PAL and NTSC DVDs for EP3.
(1) The film transfer on the PAL DVD is stored natively as 720x576 pixels. During playback, this information is stretched horizontally to 1024x576 resolution, which gives us the following corrected image on a 16:9 display:
(2) The film transfer for the NTSC DVD is stored natively as 720x480 pixels. During playback, this information is stretched horizontally to 854x480 resolution, which gives us the following corrected image on a 16:9 display:
There is considerably more vertical detail in the PAL version, though this doesn’t necessarily mean that the PAL version must be perceived as better. However, it has been shown elsewhere that the NTSC DVDs suffer from more prominent edge-enhancement artifacts, and this is another reason to favor the PAL footage in your Star Wars project.
In either case, we give up a lot of vertical resolution to the black bars, which are needed to maintain the original Cinescope frame. But if we are willing to alter the frame somewhat, a new option is available for NTSC projects.
(3) Here, the NTSC frame approximates a true, 16:9 image (there is very little letterboxing) and uses ALL of the vertical detail afforded on the PAL DVD. Thus, we are trading off the Cinescope frame for more lines of information.
Here is the question: If you are in NTSC land and own a 16:9 display, would you prefer #2 or #3? That is, would you give up the original frame for PAL-like detail?
Note. Many of us can enjoy either picture on a universal player, but this doesn’t address the audio issue, which is why I am asking people to think only in terms of a DVD that is NTSC compliant with respect to size and frame rate.
