The biggest difference between Caiman and Alligator or Crocodile leather is that the Caiman leather is not near as durable. A Caiman fuscus crocodile have small bony plates â if you bend the leather across these plates you will see that the leather creases between the scales.
According to IMAX, 35mm film has a digital equivalent of 6000 lines of horizontal resolution (6K), while 70mm film has the equivalent of 18,000 lines of digital resolution (more like 12,000 in reality).
There are two aspect ratios supported by DVD: 4:3 (also called Normal or Full Size) and 16:9 (Wide Screen). Both aspect ratios use the same picture size, however the 16:9 (widescreen anamorphic) image is horizontally compressed on DVD and then stretched by the DVD player when viewing. 4:3 is the aspect ratio of a normal TV (Image 1). 16:9 is the aspect ratio of a widescreen TV (Image 2). A 16:9 feature will be letterboxed on 4:3 TV (Image 3) or Pan & Scan (Image 1). An MPEG file carries within it a parameter for the aspect ratio information and is a flag set by the encoder. Most encoders provide an option to set this flag: for an example, see the following screenshot from the TMPGEnc encoder:
