Quicktime filters

Hi fellas

Sorry if this has been asked before but is it possible to access the Quicktime filters?

For example, can we convert an RGB video to B&W programmatically using the Quicktime classes. I’ve been poking around in the ofQtUtils.cpp and .h code and then the Quicktime.h file but can’t see anything with obvious names like “QTBlackWhiteFilter” or QTDesaturate.
