FILM APERTURE
The film option is used to select the filters when in
film processing modes.
The options are:
Safe
The film frame pairing algorithms are still
used. However, the filter does not try to
extract as much vertical resolution from
the input and the filter is tolerant of video
based material.
Sharp
The HD2200 aims to extract the
maximum possible vertical resolution
from the incoming material. Film material
can be converted to provide greater
resolution than is possible with video
material when the incoming material
contains the extra detail. However, if
video material or film with incorrect
sequence information is processed using
this filter then the output of the HD6200
will not be correct.
WARNING
If the machine is set to sharp mode and interlaced
video sources are supplied it is possible that the
picture may be degraded by the appearance of
“
jaggies”
Jaggies
/jag'eez/ n. The `stairstep' effect
observable when an edge (esp. a
linear edge of very shallow or
steep slope) is rendered on a pixel
device (as opposed to a vector
display).
