Exporting a deinterlaced master file from 25i material

I have recently edited a bunch of old material that I've shot with Canon HF10. FCPX states that my source material is recorded in 25i, a format I didn't even know existed. Now, when I export a compressed file, everything looks okay, and there's no telling that the material once was interlaced. However, when I export the master file, that is, ProRes 422, I get a clearly interlaced look on my material.

How can I export a master file that doesn't have this interlaced look? I've tried exporting from Compressor 4.1 with field order set to top first, but the problem persists.

A number of the FCP X Share presets automatically de-interlace because the assumed playback device is a computer. For example, the video sharing presets automatically de-interlace. In fact, I don't believe it's possible to output an interlaced H.264 video. A Pro Res master file. in contrast, would not be de-interlaced unless you specifically changed the project settings to Progressive.

Oh. To answer the question in your last paragraph: the easiest way is in the export dialogue>Settings:Format, choose one of the Publishing options from the drop-down. So you don't even need to use Compressor.
