critic’s choice
I have DV footage I want to export for critical processing in AE. I will ultimately output to progressive scan on DVD.
What EXPORT [to ANIMATION MOV] settings will eliminate (or, if not, at least minimize) combing and give me the optimum color and luma range for the purposes of highly critical processing in AE? -

Is there a reason not to import the native DV straight to AE and use its deinterlace / processing tools ..?

Also, if your source is DV, why do you want to export to progscan? Progressive scan should be reserved for progressive sources, most notably film in commercial DVDs.

None really, Mike, but if I might breach the area of AE’s forum, what settings should I look for in AE to get maximum color range and minimize combing from conversion to progressive.
(For example, in PREMIERE, there’s a choice between DEINTERLACE and PROGRESSIVE and I’m unsure which would give me best results. DEINTERLACE might require that I discard a field. On the other hand, PROGRESSIVE might not intelligently compensate for movement and result in combing.)

Sorry our posts have crossed, Jeff. Someone in an earlier forum posting advised me to output on MPG for DVD in progressive. I was skeptical, but was pleased with the result, except for some occasional combing artifact. Normally I would do all processing before this conversion to MPG, but in this instance, I want all the picture information I can get for the procesing.

With interlaced source material, my opinion is that this is bad advice.
AFAIK, all DVD players decode the mpeg video on the disc as interlaced. If the DVD player has progressive outputs, then a de-interlacing chip (Faroudja, et. al.) inside of the player de-interlaces the video to that it can be sent to the progressive outputs.
Let’s talk NTSC. All non-HDTVs cannot use a progressive signal. The raster in SD sets cannot scan fast enough to paint all 525 lines every 30th of a second. They must be fed an interlaced signal.
Let’s talk HDTV. All HDTVs have a de-interlacing chip built in. The chip de-interlaces an interlaced input signal. Progressive scan inputs on the HDTV bypass the set’s de-interlacing chip, allowing the unmodified progressive signal from the DVD player (or the HDTV tuner) to be displayed. So which is better, the de-interlacing chip in the DVD player, or the de-interlacing chip in the HDTV set? Obviously, the answer to that will vary *a lot*.
My point is that you gain nothing (and may *lose* quality) by de-interlacing an interlaced source that is destined for DVD.
