Compressor Settings?
Hey all,
Ive got a question about DVD settings in compressor but seeing as theres no compressor forum, i thought this would be the best place to ask. Im trying to burn a PAL DVD using custom settings so that I can get the highest bitrate. As I understand, PAL interlaced footage is interpreted as lower field first. However my film school lecturers tell me to set the output fields in the frame controls section as upper field first. This confuses me as im pretty sure theyve always said lower field first for other programs. Is this an entirely different setting? Or am I just looking too far into it.
Thanks!

Only DV PAL is lower field first, SD PAL is upper field first.

This confuse everybody.
When we see the Sequence Presets in FC we find that certain codecs (DV, DVCPro50) are Lower First.
Those presets are to edit natively footage that have been recorded in tape as Lower first.
They are captured as Lower First too, of course.There are also others Sequence Presets for 8 and 10b (UNc and Prores). Those are Upper first and are designed to capture typically “DIGITAL BETACAM footage. This footage is recorded in camera as Upper First, and logically is captured as Upper First.
I GUESS that you are working with DV but you want to render to a high quality codec (8/10b Unc or Prores). You don’t need to change to Upper.
Those fields order that we commented are a must when you capture or print to video.
Inside of the computer, the field order is up to you (as long as you use the “Shift-fields when needed).
You can export your Proress or 10b Unc Lower First and hen make a Lower First MPEG-2 for our DVD.
As long as you don’t try to print to DigiBeta that file, no problem.By default applications like FC, Compressor, etc, expect any PAl 8/10b or Prores to be Upper.
You need to make sure that the file field-order is properly identified.
Going to an MPEG-2, you have to check it In the Inspector/Encoder: “Field Dominance” to identify your incoming clip field order.
Hope this is not a mess.

I thought they were the same thing?
It was shot on a Canon XH A1 using standard MiniDV tapes, does this qualify as DV PAL?

Well all I am trying to do is export my sequence (which was captured from a MiniDV tape) to the highest quality mpeg2 using compressor. So im guessing this does qualify as lower field first and should stay this way for the mpeg?
Thanks!
