Sorry if I haven’t been clear. I haven’t used a separate 3d application, I’ve just been using the 3D functions in AE 6.0.
All of my source footage comes from uncompressed Quicktimes exported out of an Avid Meridian from an original Digibeta NTSC source (tapes digitized at 1 to 1 maximum resolution). When I experimented with interpreting my footage in AE, I used the lower field first setting.
