Frame Controls pane

This pane of the Inspector oers automatic and customized settings for advanced image analysis,

including frame resizing, clip retiming, and deinterlacing.

Frame resizing would be necessary when transcoding between a high-denition (HD) format

such as 1080i and a standard-denition (SD) format such as DV-NTSC. An example of frame

retiming would be when transcoding between video formats with dierent frame rates such as

NTSC (29.97 frames per second) and PAL (25 frames per second).

Filters pane

You use the Filters pane to add lters to your setting. You can use lters to perform tasks such as

gamma correction and noise removal.

Select the checkbox next to any of the lters you want to include in a particular setting. Use each

lter’s sliders or arrow controls to adjust your lter settings as necessary.
