Thanks Rafael you helped me last week with this issue.
I’m ripping using Protube imedia Converter software (seems pro) using a pro res 422 setting @ original size 640×480 (720 is not an option) (MPGstreamclip will not work with 10.8, the QT component is not compatible)
I then imported in fcpx and optimized media, then created a timeline ntsc 720×480 both anamorphic and not, expecting to see my 640 footage with two black bars on the sides. I thought from there I could upscale it to remove the black bars and either have a cropped image or transform it to fit.
The anaomrphic timeline appears 853×480 in fcpx window even though the properties setting read 720×480 and the non-anamorphic timeline appears 640×480 (without black side bars) even though the properties read 720×480
