No Broadcast Monitor
Hey Guys,
I’m exporting a movie for delivery that the delivery specs are 1080i60. My timeline is 10bit 1920×1080 square pixels at 29.97fps. We are delivering this thing on a hard drive, not tape. 95% of this project is animation, that was done in Maya and then composited in After Effects, and is progressive. The other 5% is live action footage that is interlaced. My question is, should my sequence field dominance be set to “none”? When I do this and export a quicktime movie, it looks great (though from my understanding, the live action footage is being de-interlaced). If I set the field dominance to lower and export a quicktime movie, I can see the fields in the live action footage. Now here is the kicker…the place I’m working at does not have a broadcast monitor, otherwise it would be a lot easier to know if things are going correctly. If I am asked to deliver 1080i60, am I not giving them what they want by exporting a qt with no field dominance? I just don’t want the network coming back and saying that it doesn’t comply with their specs.
Thanks in advance for the help,
Eli -

1080i60 is interlaced which means it has fields which means you should *not* give them a progressive file.

Thanks Andrew,
From what I’ve read elsewhere on the Cow, it seems that 1080i60 should be upper fields first…is this correct?

Hi Eli,
All the HD interlaced formats are Upper-first.[Eli Mavros] “should my sequence field dominance be set to “none”? When I do this and export a quicktime movie, it looks great (though from my understanding, the live action footage is being de-interlaced”
If you haven’t use any de-interlacer filter your clips are not being de-interlaced.
They may be looking OK in your canvas, but be very careful.
Your Progressive animations won’t have problem in an interlaced sequence.
So you have two options:
– Make your sequence Upper-first and drop everythin on it.
– Make your sequence NONE and de-intelace the footage.
Lately I’m going to the second option.
Everything de-interlaced.

Yes, and you can confirm this by simply choosing any 1080i/60 preset in Final Cut Pro. All interlaced HD formats are upper field first to my knowledge.
Though in reality, it’s 1080i / 29.97 so you’re already in the correct frame rate.
