It does... but it's pros/cons IMO . Easy to get burned if not careful

If file is tagged correctly, the source filters read and pass on various metadata as clip "props" or properites

All manipulations "automatically" assume or take on those values, unless otherwise specified . e.g. if you resize or RGB preview ,everything is done correctly as per the metadata. e.g. if file was interlaced, tagged interlaced, then the resizing and conversion to RGB will be done interlaced aware

If file was tagged correctly, great. Everything just works(TM)

If it's not, trouble. e.g. if you get file from somewhere else. e.g handbrake often tags incorrectly . eg. progressive PAL DVD's are tagged interlaced. You end up having to double check everything.
