I listed all the HD acquisition formats and modes - there were more than 70 by my count.

At least all HD is upperfield, and the full raster sizes are fairly straight forward.

In PAL we have two neat DV issues - one is that all DV is Lower-field, where PAL 601 is Upper-field. The other is that all PAL DV is 4:2:0 except DVCPRO which is 4:1:1... So much pain. At least we only have one SD framesize.

That's what I mean. How about just a few "standards". Can't we all just get along. ;-)

Could be worse. In 625-line, DV has the opposite field ordering from 601.

Thanks Greg. More numbers, my head's going to explode.

Thanks, Terry. Sorry for the delay folks. I've been snowed under, as it were.

1080i interlace is always Upper Field, or Odd, ordered. That applies to all frame rates. Note that this is opposite from 525-line (NTSC) which is Lower Field, or Even, ordered.

Greg Staten seems to be watching this list, any answers for us?

HDV is upper field first. Not sure if that applies to all HD codecs though.

Is there a standard field dominance for 1080i 29.97 footage? I am editing on a Adrenaline HD and on a Symphonty Nitris. In the past I have edited and exported NTSC material using lower field. Is this correct or should I be using upper field, specifically for QT export to a graphic workstation.

thanks,
