I'm having this problem...
This footage was shot 60i, imported as such and edited on a 29.97 timeline, and is headed for dvd. I exported using all the following export methods:
quicktime movie (the first one), dv ntsc 29.97 interlaced->comressor, mpeg2
using compressor... mpeg2
using quicktime...
The problem is, when I try to copy and paste clips from one sequence to another the opacity and sound level settings never come with. This is true whether I use copy, cut, or drag to move and happens whether I am moving to a sequence with identical settings or one with different settings...
