JLDI
Justify pixel clock rate for LDI formats
Class Format editor control
Description Scales the horizontal timing parameters of the format currently in the edit buffer. (For the
801LD used in digital mode, the default is set at 224 MHz.) The parameters are scaled to
produce the given pixel rate while keeping the horizontal scan rate as close as possible to
its original value. The following parameters are scaled: horizontal total pixels, horizontal
active pixels, horizontal sync delay in pixels, and horizontal sync pulse width in pixels. The
parameters are scaled so that their periods, in microseconds, are as close as possible to
their original values.
