I'm using Avid Xpress Pro HD 5.2.4 and Quicktime Pro 7.4.5, I'm trying to export to a quicktime movie file and in the Export Settings menu I don't get the box where I can choose between - Odd, Even or Single Field. In the Video Format box I get Width x Height, Color Levels and Pixel Aspect ratio, but no option for File Field Order which seems to be what everybody else has as an option. What's my problem?

 According to the version matrix, you should be running QT 7.0, not 7.4.5.

Sounds less like of a Quicktime issue here (not that running 7.4.5 isn't an issue in of itself), but more like an issue with the project type being progressive. The options they've listed are the typical ones presented by Xpress Pro.

If robbidouglas would kindly tell us the project type their working on first of all, that'd be really useful.

The project type is 25p PAL

The project type is 25p PAL, will try the quicktime 7 see if that works.

Ok, it's because the project is 25p, so I've changed it to 25i ... thanks for the help.
