I am not too sure if technically there is a differnece in the way the terms are used generally however I think I saw a post where Dave LaRonde used them as slightly different terms. (but cant find it just now to reference)
They both seem to be used in terms of describing field order in an interlaced image.
I have worked in broadcast tv for over 20 years in the UK and have never heard the term field priority used except seeing it here a few times. It may of course be a UK/US language thing.
Indeed I just “Googled” field priority and the first page of results are not TV related at all.
The first thing to appear using the term in Google is on page two, a COW question on field issues then another couple of pages of non tv related entries. I did not look much past that. So maybe its a term that was coined here ?Obviously if you “Google” field dominance then you immediatly get pages of tv related content.
Which is a pretty long winded way of posting “I dont quite know” however it seems that field priority is not a widely used term – at least not indicated by a simple Google search.
Perhaps others know different.

Some day you Brits are just going to have to learn to speak proper American. 🙂
Field “dominance” and “priority” refer to the same thing. Some will say “lower filed first” (indicating priority), while others say “lower field dominant.” It’s just two different ways of indicating the same thing.

Well I guess they are not entirely unrelated… you want the same field dominance as your field order or you run the risk of field flashes if you edit at a switcher cut point…
Dave’s right. Both dominance and priority are expressions of field order. It all means the same thing.
Ironically DRW, I read recently that Americans speak English more similarly than modern British and that a lot of regional accents in England have been formed over the past 400 years. Americans, although they have developed an accent, are more rhotic which was how English was pronounced 500 years ago. An excellent example is the word ‘calm’ where the ‘l’ is sounded by Americans but not by British or Aussies.

FIELD PRIORITY makes sense when the footage is being de-interlaced.
You can chose which field to keep and which one to interpolate when you are not doing “frame blending”.
You find that in most pro deintelacing filters
