Software HD to SD conversion

This is particularly tricky when you're trying to get from 1080i50 to MPEG-2 NTSC 480i.

My current methodology is:

* Dump final edits to disc as HDV.
* Convert HDV to PAL DV (Avoiding Compressor's dodgy PAL -> NTSC methods, but by using, at most, a combination of 'Better' resizing and 'Fast' deinterlacing as any more makes a 12 hour transcode a 400 hour transcode on a dual processor G5. Awesome.)
* Import DV PAL into ProCoder to Standard Convert to NTSC.
* Profit

Caveat: One would like to import HDV, or even Apple's Intermediate Codec, direct into ProCoder to get this as one step, but Apple Quicktime on Windows doesn't fucking support either. Thanks guys, you make my life a big smile.

So that's done. My first results are pretty crappy - seriously wank looking motion blur, some visible interlacing artefacts. Now, do I rent the tape deck in again and re-capture using the deck's built in down-conversion or do I attempt different compressor settings in an attempt to eliminate the dodgy motion compensation?

As the latter is free, I'm going to try that.
