Sequences and Deinterlacing
The situation:
1. I’ve got some DV-NTSC footage that I’m done editing.
2. I also have an After Effects title (NTSC composition, rendered in Animation)
3. This project is video for the web, so it needs to be deinterlaced.My questions:
1. After Effects doesn’t generate interlacing when you use the NTSC preset composition settings, does it? It doesn’t look interlaced to me.2. What is the best way to deinterlace my NTSC footage without losing quality on my AE title. Put the NTSC footage in its own sequence?
3. What about settings in Compressor? I assume if I deinterlace in FCP, then I should not choose any deinterlace settings in Compressor, correct?
Thanks for any help clarifying this for me!

You have two options. Deinterlace your footage and then render a progressive web movie or leave your footage interlaced and deinterlace the movie while compressing for the web in compressor.
[Nate Hanson] “1. After Effects doesn’t generate interlacing when you use the NTSC preset composition settings, does it? It doesn’t look interlaced to me. “
It’s not dependent on your composition settings, it’s dependent on what you have in your output module. You can choose to render with fields or without. If your footage is interlaced, I’d render with fields.

Thanks for the response, Jeremy!
I want to do option 1: “deinterlace your footage and then render a progressive web movie”
Do I just change the field dominance settings in the browser window (from lower to none)? Or should I apply a deinterlace filter to my NTSC footage?
Thanks!

Option 2 is much easier.
For option 1, you need to deinterlace the footage and FCPs built in deinterlacer is not that great.
I recommend a plug in such as revision’s Fields Kit.
Changing your field dom settings isn’t going to do it. If it were only that easy!
If you don’t want to buy anything else, I’d export a graphic/textless version of your sequence and then deinterlace using compressor. Then reimport that movie and add your graphics back to it. Export and compress for the web.

To avoid the title being rendered as DV, I would drop the DV footage and the title into a ProRes or Uncompressed timeline.
I have used the Nattress deinterlacers which are much better than the FCP ones. Haven’t used Fields kit so can’t offer a comparison.
