Workflow for selecting the correct image area in data mode!
Defining of vertical file size
The following workflow for selecting the correct image area is supported by the
Spirit DataCine film scanner (Menu Sizing):
a) The desired portion of the image area is selected with the sizing controls (fixed
aspect, fixed repro, ACA emulation, cinemascope, zoom H&V, Sizing and Posi-
tion H&V).
b) At the data output, the file size is selected and the selected image will be
squeezed into this size without cropping any image information.
c) If blanking area within these files should be avoided, than the reproduction ratio
has to be adjusted to the ratio of the selected image.
d) Helpful for defining the correct file size is the description of the fixed file formats
in this chapter.
Here two examples how to calculate file sizes without blanking:
1. Sizing menu selection:
Fixed Aspect CA/AC
Fixed Repro OFF
ACA emul OFF
1920 x 1080
959 x 539
24.45
18.80
17.48
Fig. 450: Menu ”Sizing”, submenu “Repro”
The table 437 on page 4-147
“35mm scanning formats, 4 perf, Full Aperture LGA and Gate”
lists a size of 24.45mm x 18.80mm => aspect ratio of 1:1.3.
For a desired horizontal file size of 1920 pixels, the vertical file size
without blanking is 1920 x 18.80 / 24.45 = 1476 lines.
Vertical Size
1476 Lines
