doing the same with the media manager the vectorscope shows a a different white and there are stairs in the video (see within the white circle on the helmet):

since now, i did exporting within final cut to quicktime. but i would like to use the media manager. using the manager reduces videoquality. my class1 monitor shows a little bit unsharper quality. does anyone know why and which workflow do you use?

thanks for your help!
