Why are my DeckLink-captured Sheer videos the wrong resolution?
As reported by Blackmagic Design, Final Cut fails to call ‘VDSetPreferredImageDimensions()’ to inform the DeckLink ‘VDIG’ driver of the image resolution, so the driver has to infer the image dimensions from the size of the capture window. However, Final Cut sizes the capture window to half-size when recording high definition, which is indistinguishable from setting the capture dimensions to 960×540. Blackmagic Design handles HD codecs as special cases, and always records these at full HD frame size even if the capture window is half-sized. The Sheer codecs were added to this list by August of 2006, fixing the problem. So if your DeckLink-captured Sheer videos have the wrong resolution, you need to update your drivers.
