Setting Driver Properties
RefSize tab
Changes made to the RefSize tab (Figure 25) 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.
