My situation: I've got 59.94fps progressive video, and I need to downconvert it to regular old NTSC at 29.97fps. Premiere Pro lets one export a 59.94fps project as such. However, a quick test confirms my suspicion: All Premiere Pro does is pick every other frame and use it to generate BOTH FIELDS of the new 29.97fps interlaced video! It completely ignores the fact that I have 59.94 perfectly usable frames per second that it could use for each field. (This was confirmed by inserting a single frame of text at frames 0:10 and 0:21, and then importing the resulting video and seeing whether or not the text had been rendered. The text was resident at 0:10/11 but not at 0:20/21.)

So! What I need is a plugin that will do a PROPER job of interlacing my video, since Premiere Pro is evidently not up to the task. Anyone have experience with something that will in fact work? Thanks.
