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
retiming 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 .
