DVD creation - Mpeg Field Order.
on Jul 31, 2013 at 2:24:03 pm

I'm sorry, this topic has probably been discussed to death over the years but I keep getting mixed opinions and am overly confused.

I shot and edited footage at 1920x1080 25p.

Now to make an Mpeg in compressor in regards to 'field dominance' do I select 'Progressive' or 'Upper Field'? I am in PAL land and here Upper Field is what we use.

Same question regarding 1280x720 50p footage. This time it's 50p. Do I again select '25p' and which field dominance? Progressive or Upper?

if it's a PAL DVD you're trying to author then it's 25p lower field first for interlaced material or you can leave it as 25p progressive if you like.

PAL is upper field first except for DV codec if I'm not mistaken.

Yeah PAL is upper.

But still I'm not sure if I need to create the Mpeg for DVD in Progressive or Upper (interlaced) mode.

Footage is 25p, My editing timeline is also 25p. So now that I need to make am Mpeg for DVD are you saying I should make it Upper field first? (interlaced?) Or leave it progressive?

Clearly I've been making 'em wrong for the last 15 years :-/

Bottom line, if you're coming from a progressive source, make a progressive DVD.

what will be the purpose of this DVD?

most of dvd players can do 25p, it really depends on player hw.

I would stay progressive as with proper settings on equipment you could get progresive output on LCD tv/projector/computer. with wrong settings player/tv/projector... would interlace your progressive footage, which isnt as much hit to quality as other way around (considering cheap electronics, i would assume all good electronics can do 25p). Only downside is very old players will not accept 25p.

I'd be very surprised if there's anything left in the world that couldn't cope with a progressive DVD.

My understanding was always that DVD doesn't require any specific field order - upper first, lower first, progressive are all fine.

I usually specify lower field first because traditionally PAL SD material came from DV which was always lower field first and so the majority of PAL DVDs (at least here in Australia) are either lower field first or progressive.

Basically match the DVD field setting to the source file and keep the field order consistent throughout the DVD and all should be well.

[Jeff Kirkland] "My understanding was always that DVD doesn't require any specific field order - upper first, lower first, progressive are all fine. "

I agree. (the standard spec. is UFF though, except for DV source)


[Jeff Kirkland] "Basically match the DVD field setting to the source file and keep the field order consistent throughout the DVD and all should be well."

Exactly!
