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.
