Deinterlacing
I had a question about deinterlacing. I am doing a wedding video for a friend and its all edited in Premiere and then I brought it into AE and did all of the color corrections and transitions etc….I will be putting it onto a DVD. What is the best way to render it out for the nicest looking footage. I am guessing I should deinterlace it but how should I do this? Can I render it out of After Effects as a quicktime movie, bring it back into Premiere and render it out Deinterlaced there or will I lose quality. Or is there an easier way to do it. Please Help.

if the footage was shot interlaced at 29.97fps, your best output for dvd will be interlaced at 29.97.
deinterlacing and rendering progressive at 29.97 will lose some image quality and some smoothness. rendering progressive at 23.976 will lose more smoothness.
when effecting your footage in ae, it is best to set the interpret footage settings to separate fields, but then render back to the proper field dominance (a setting in the render settings from the render queue).
you may want to render progressive at 29.97fps if you feel that the dvd will be viewed more on a computer than a television… in my opinion, the interlacing on a computer screen looks worse than the reduction in smoothness on a tv.
if you wanted to render progressive, choose to separate fields, smooth edges. then in the comp enable on frame blending (frame mix, not pixel motion). this usually helps smooth the motion and hard edges a bit by blending the image data from both fields.

[moldyboot] “if the footage was shot interlaced at 29.97fps, your best output for dvd will be interlaced at 29.97.”
I agree. Leave it alone. The best way to get the progressive look is to shoot progressive.
If you really want to deinterlace, try FieldsKit, but I don’t think you’ll get a big improvement, and you’ll just lose image quality, as Kevin wrote.

Ok so no deinterlacing. What are your suggestions for rendering out of AE to use onto a DVD. And what are your suggestions for compression settings?

You must render to 720×480 for NTSC, or 720×576 for PAL.
I like to render to a high-quality format such as Animation, Quicktime. Then I take that movie into Compressor to make an MPEG-2 movie, encoded using 2-pass Variable BitRate encoding (VBR). Then I import that file into DVD Studio Pro and author the DVD.
It’s the same for other apps:
1. render high-qual MOV or AVI from AE
2. compress in a compression app (compressor, squeeze)
3. import into authoring app (DVDsp, Encore DVD) -
When I use Sorenson squeeze and render it out as a mpeg 2 when I go to import it into Encore it is in two files. A audio and video file. Am I doing something wrong?

No, that’s normal: you should see a video file and an audio file.

I figured out how to get it into one file. Thanks for all your help. You have been a big help.
