Mscope™
Mscope enables the use of anamorphic lenses without
the requirement for Data Mode compatible equipment.
Mscope Output
Mscope, like HD Mode, outputs fully processed images,
but uses the full 1.33:1 sensor aperture to create a
1920 x 1440 oversized HD image. In order to output
this oversized image using standard HD interfaces it
has to be split into two separate HD-SDI streams. Each
1920 x 1080 4:2:2 YCbCr 10 bit HD-SDI stream contains
a 1920 x 720 letterbox image in 2.66:1 aspect ratio. Link
A contains only even lines from the original image, link B
only odd lines. When shooting with anamorphic lenses,
each stream therefore directly shows a de-squeezed
image that can be used for preview and editorial.
Mscope Recording & Postproduction
Any recorder supporting SMPTE 274M dual stream/
dual camera input can record Mscope signals.
Depending on the recording system in use,
recombining both streams to the original 1920 x 1440
image may be available as an automated export
option or may have to be done after ingest.
As the Mscope image has a de-squeezed aspect ratio
of 2.66:1, it provides some room for respositioning a
shot before it is cropped on the sides to the desired
output aspect ratio (2.40:1, 2.39:1, 2.35:1). With a
deliverable aspect ratio of 2.40:1, the output would
be cropped and, if necessary, de-squeezed to:
1728 x 1440 pixels for a 35 mm release print (scope)
•
3546 x 1440 pixels for digital cinema release (flat)
•
1920 x 800 pixels for release on HDTV (flat)
•
Mscope Benefits
Fully processed live HD for preview and editorial.
•
• Mscope image contains approximately 80% more
scanning lines than equivalent 2.39:1 images cropped
from 16:9 HD images shot with a spherical lens.
• Mscope combines the use of anamorphic
lenses with the economy of HD acquisition.
