Fun with Fields……
Hello all
I’ve been getting a bit of a headache recently with some problems I’m having with field dominace in FCP.
I’m working in a mixed Animation DV-Pal timeline. The timeline is set to DV-PAL lower field first. Basically FCP’s defualt settings for working with DV-PAL.
These clips are going out for broadcast via a Clarity broadcast system and in order for that to import them properly they need to be rendered out upper field first. Clarity then interperets them correctly and they all look lovely when they go out on TV…..though they look completely wrong on FCP’s broadcast monitor.
To achieve this I have simply been editing the clips in FCP at lower field first and then when it comes to exporting the clips going into clip settings, changing the field dominance to upper field and exporting at current settings. This has been working fine for the client even though it seems a bit odd to me.
The problem that has just arrisen is that an edit that another editor has put together on a different machine is refusing to play ball. All the settings on the other edit suite are the same as on mine however changing the projects field dominance seems to make no difference to the way the clip is interpereted….. swapping from upper to lower field dominance requires no rendering and the footage plays out great on the broadcast monitor in either setting and the interlacing is all wrong once it’s loaded into the Clarity for broadcast. Even applying the shift fields fitler makes no difference although it does require a render.
Exporting the clip as an Animation DOES seem to mess with the fields but this is not practical as the files are too large….. Basically I just need to get this clip out with the WRONG field dominance but I can’t seem to swap the fields. This seems to imply to me that I’m looking at Progressive footage but FCP confims its DV-PAL with a lower field first dominace…… Any of that make sense. Sorry for the long post and Any ideas????

Yeah thanks for that……
However what’s throwing me is why changing the timelines field dominance has no effect on the interlacing of the footage? (no need to render or anything. Adding the reverse fields filter requires a render but no difference at the end). Is this be because it has been shot progressively and someone has failed to mention this? Or is something else going on here?
Why when the footage is played out in the Animation codec are the fields now swapped?
Cheers for the help so far
