Hello Terry,

I have had this EXACT issue multiple times. The issue is not that the footage is 1080, as you can edit progressive just as easy as 720. The compressor is also fine. The trouble is with poor FCP coding…

I found a workaround which will hopefully work for you.

1. Make a new sequence.

2. Drop a piece of 1080 progressive footage into that sequence, and when FCP prompts “do you want the sequence to match clip settings yotta yotta yotta” you say yes.

3. Open the sequences that is giving you problems, cmd+a (select all), then cmd+v [copy].

4. Open your new sequences. cmd+v [paste].

In some instances I have had to do this multiple times after opening/closing FCP. Its a quick workaround though as compared to waiting for the render, and ending up with interlaced footage.

-Hope this helps!
