MV ReInterlace DirectShow Filter
The MontiVision ReInterlace DirectShow Filter is used to
create interlaced video content from progressive source footage.
The filter outputs half the frame rate it receives - e.g. 25 fps
output for 50 fps input. The filter is designed to work in
combination with MV DeInterlace Temporal, which de-interlaces a
video signal by outputting resized
progressive fields. An example scenario is shown
below.
