v.dig

v.dig is the object that digitizes incoming video streams from external sources.


v.dig is the object that digitizes incoming video streams from external sources. It has two modes: vdig mode and seq_grabber mode. seq_grabber mode uses standard QuickTime 'sequence grabber' calls to acquire video. This is the method used in most video editing programs, for example. The problem is that some (especially Formac ProTV) standard driver code has some problems that result in less than optimal softVNS 2 performance. This is the reason for vdig mode. In vdig mode, I use lower level (but usually still Quicktime Standard) calls to acquire video. This gives me more control over some useful aspects of the process. In most cases, vdig mode is better than seq_grabber mode. However, seq_grabber mode does perform better in some instances (XLR8 InterView) and theoretically offers broader compatibility. The preset menu in the v.dig configuration window offers some optimal presets for specific digitizers.
