This is correct.
"i" = interlaced
"p" = progressive
Many people shoot in non-interlaced modes nowadays, but some don't,
and there is "legacy" footage...

I think 1080i is interlaced, 1080p is not.
Cheers,

And you don't have 1080p available from the source? That wouldn't
be interlaced, methinks.
Thanks!
This is exactly what I needed!
just curious: why do you want to eliminate every second line of
an image?
Video cameras interlace two images taken a fraction of a second
apart into a single frame, leading to interlacing artifacts (a
serrated edge on fast moving objects).
Your script will eliminate one of the fields, thereby isolating a
single "time slice" of reality.
This comes at the expense of 50% loss in vertical resolution.
Luckily, an HD image has 1080 pixels to start with, so 540 pixels
vertical is plenty for web use.
Thanks, can't wait to try it!
