field order HDV

I work for a company that shoot with sony z1's and shoot dv and hdv. we are required to place a de-interlace filter on our footage to generate the look the director requires- change the field order from lower to upper. But i noticed today that the HDV footage captured in already has its field order set to upper. Is this right? I generally only work with DV where the field order is lower and this is the first time i have been given HDV to work on.

I'd just like to know if this is correct and do i still have to apply the de-interlace filter?

HDV is upper. When you deinterlace you can pick whichever field works better. The other field is being dumped.

cool, so if i applied a de-interlace (or fast de-interlace as they use here) and set it to upper would this be pointless and waste of rendering time? I'm starting to think so but please do tell me if this isnt the case.

Thanks for the reply by the way....

i just did a test on a clip half with the fast de-interlace (set to upper) and half without and there is a difference.
How comes? Any enlightenment would be much appreciated.....

Whether you deinterlace or keep the interlace depends on where your video is going to be seen/screened. Deinterlacing is pointless if it is going out for SD broadcast/analog tvs. In this case, you'll just be throwing away half the picture.

Where are you seeing the footage? Is it off a CRT or the canvas screen?

I'm watching it back through my pal monitor and the canvas and can see the difference in both, the de-interlace seems to be part of the procedure here as they like the look it provides over the fully interlaced look.

A selling point for the products here seem to be the film-esque look that gets made here. Though i dream about how much time would be saved if the had cameras that shot progressive.... But hey its not my gig i just work to the sheet!

Thanks again for the replies..
