RefSize tab
Changes made to the RefSize tab (Figure 19) apply to all video previews and captures on the
currently selected device. The RefSize tab controls the features related to the reference size, format,
and proportions of the video. Most users can set up this page once and only refer to it occasionally
since this page does not provide everyday control for the final output size of your video. You’ll likely
control final output size from your application, the Size and Crop tab, or from the Pin Properties
dialog described in the next section.
