Frame Controls Pane
This pane of the Inspector offers automatic and customized settings for advanced
image analysis in frame resizing and frame retiming.
Frame resizing would be necessary when transcoding between a high definition
format such as 1080i and a standard definition format, such as DV-NTSC. An example
of frame re-timing would be when transcoding between video formats with different
frame rates such as NTSC (29.97 frames per second) and PAL (25 frames per second).
For more information about the Frame Controls pane, see “
About the Frame Controls
Pane ” on page 196.
