Just caught wind (via FreshDV) of a free little program with big features: namely, it can encode to ProRes on Windows.
Cinec is a “multi video encoder for Windows” made by Cinemartin. It’s totally free, and will encode to all the flavors of ProRes (including 444), DNxHD, XDCam, and H.264. Pretty sweet for free, huh?
It can also do some simple cuts/trims (think MPEG StreamClip). I’ve only done a few encodes with it, but it seems to be a nice little utility for any PC-based editor. Just export a Quicktime Reference movie or full export, throw it into Cinec, and you make the FCP people happy.
