Hi
Has anyone come across a way to convert an MPEG2 file from progressive to upper field first.
Thanks

Well, if you've only got 29.97p source, getting 59.94i will require motion interpolation, which is really slow. Compressor can do this, as can the Algolith and Twixtor plugins for After Effects. However, even in SD, assume an hour or so of rendering per minute of source even on a fast computer.
