Deinterlacing issue with full HD

Dear Creative Cow,

I am exporting from FCP and getting slightly confused regarding de-interlacing.

The footage is Apple ProRes 422, full HD 1080 50i.
My sequence settings are set to 1920 x 1080, HDTV 1080i (16:9).
Pixel ratio square, field dominance upper, timebase 25.
Quicktime video settings: Compressor Apple ProRes 422.

The question is: do I de-interlace my footage by adding the video filter 'De-interlace' to all the individual clips from the FCP effects box, or do I de-interlace at a later stage/in a different way?

In the sequence setting under 'compressor advanced', there is a box checked for 'Interlaced' where there is a choice from a scroll bar for either bottom or top field first.
Should this 'Interlaced' box be checked or un-checked? And does this affect the adding of de-interlace from video filters? This is the stage that is confusing me.

Hope you can help! Appreciated enormously!

No need to de-interlace.

As per Steves comment - not sure why you need to de-interlace. The de-interlace filter on FCP is not the most "subtle" of deinterlacers. You will likely degrade your footage if you use that.

best wishes

Thank you both of you!

I am still a little confused though.
I understand that you both say I should not add the de-interlace using the video filter in the fcp effects, but what about the issue of the compressor - it is automatically checked 'on' as 'interlaced' - should I uncheck this?

And my footage is interlaced footage - should I not de-interlace it at some stage?

how would you export the finished product?

Thanks again!
