7.1 CONCEPT
The only thing we know about tomorrow’s high definition TV is its
aspect ratio of 16/9 (1.78). This new ratio is now taking the place of
the 1.85 (USA) and 1.66 (Europe) ratios. This is why it is time to
re-examine the Moscow’s idea (1962) of the 3-Perf format.
As a matter of fact, an image with the 1.78 ratio, with its both edges
close to the 35mm film perforations, is a little higher than 3 perfo-
rations high. Why should we keep a huge amount of unused emul-
sion between two images (i.e. why should we keep filming in 35mm
4-perf)?
35mm standard 35mm 3-Perf
3-Perf presents three main advantages:
• Saves 25% on raw stock.
• Increases magazine running time (a 400’ roll increase from 4 1/2
to 6 minutes).
• Allows for the camera to run quieter.
