back a few years ago when I was shooting with sony z1's, I used Nattress' conversion plug-ins and they worked great! http://www.nattress.com/
( Graeme Nattress is a member of this forum and always helpful if approached ) I used his "film look" plug-ins as well... especially the bleach bypass... good stuff.
another quick option is to ( if your on a mac ) drag your quicktime file into itunes and then convert it to appletv spec..... that will make it deinterlaced and 960X540.
Quicktime pro also has the appletv export preset.... once exported, you can open it again and then save as a regular quicktime for the web.
