View Full Version : What resolution is 16:9 and 35mm

01 January 2005, 03:58 PM
My question is, what resolution would a widescreen movie be. Id assume its larger then standard NTSC or PAL. Also, is 35 mm a super high resolution different then 16:9... ad assume so since its in box form.

16:9 for NTSC is 720x480 with a pixel aspect ratio of 1.2 and a film aspect ratio of 1.8 as opposed to 4:3 with a PAR of .9 and a FAR of 1.3.

Now HD depends on which one your using 720p (progressive) and 1080i (interlaced)

Heres some reading, that should explain everything:

as far as 35mm

May I heartily recommend you use the Search function here at CGTalk for threads about resolution or iff and movies like "Jimmy Neutron" and "Toy Story."

Here's one:

You'll see that "Toy Story" was rendered at "1.5K" or 1536 pixels for the 16 number, and I believe that "Neutron" was even lower.

Two good reasons to aim higher are a) to have more to work with when compositing and b) to allow for finickier audiences.

LightWave allows for saving the entire project in PSD layers, which is nifty.

Bear in mind the important difference between resolution and aspect ratio. The true meaning of "resolution" is how many discernible pixels there are within a given area of image-space. The effective resolution of photographic film is very high indeed, regardless of how large the piece of film might be. Obviously a larger piece of film can store a larger picture, and can do so with less bending of the light either on recording or on playback, but the resolution of a piece of film does not depend on the size of the frame, nor its proportions. (The signal-to-noise ratio obviously does, because if you over-enlarge you begin to see the silver grains.)

Aspect ratio, on the other hand, is strictly an expression of the proportions of the frame: the ratio of width to height.
