HD 1080 vs HDV 1080i

Today i have checked the tabs in the artists resources and i find that HD 1080 sells better than HDV 1080i clips.
So i checked my clips at Pond5 and in the preview it says that they are HD 1080.
That confuses me a little because:
My Camera is a Canon HDV 1080i. I export the clips as Quicktime.
On the pond 5 edit page i tick source is "HDV" and clips are "interlaced".
So shouldn`t be my final clips on Pond5 "HDV 1080i"
But they are HD 1080....
I am a little confused now, could somebody send me some Light into the dark?

Interesting, mine show as HD 1080 also.
I guess everyone's HDV video is showing up as HD and that's why the HD is reporting more sales then HDV.
I doubt more people here have true HD cameras then HDV cameras.
P5, can you look into this and correct it?

Aren't you de-interlacing the footage before uploading it? If so, P5 would see the re-encoded footage as HD, wouldn't it?

Mine are interlaced.

Thats interesting, i just checked my clips and they are obviously de-interlaced.
Well, i thought that the clips get rendered as Quicktime interlaced, but its not.
I just checked my software and from the programm i cannot export quicktime interlaced, only quicktime progressiv.
That means, my final clips are progressiv, so i am supposed to tick on all my clips "Progressiv" instead of interlaced?
Lots of stuff to learn on that codes and rendering things....

What software are you using? You can watch them in the player and see if they are 'interlaced' when they come out... try one of your final .mov files at full screen, you'll know then.

We currently analyze the codec to determine if a clip is called HDV vs HD. If it is in the HDV (mpeg2) codec and has standard HDV resolution, we will call it HDV.
Clips in the Photo/MotionJPEG, with HD resolution are listed as HD. We will probably change this shortly, so that it reflects what is in your Camera Source field.
This doesn't have anything to do with interlacing, although we label HDV codec clips at 1440x1080 as "HDV1080i" because there is no 1080p version of the HDV codec.
BTW, please DO NOT deinterlace interlaced footage unless you have a good reason, as it entails a good deal of quality loss.
In Quicktime you can tell if a clip is interlaced by going to Window > Movie Properties and clicking "single field" under Visual Settings. If it looks different when checked vs unchecked, it is interlaced. It's always a good idea to verify that clips are full quality (no deinterlacing etc) before uploading, by comparing them with the footage as it was captured.

Well said Tom, for some reason so many people believe Progressive is better than interlaced. Not so, do what your camera is designed to do the best and leave it in same format for processing. Graphic artists start with a progressive workflow, most video cameras do not. Even though my Canon XH-A1 can shoot 24 and 30 f, a quasi progressive, it still is better designed for interlace.

Thanks everybody for the detailed answers....
@ phantomewo and dapoopta :
My intention is not to change the interlaced clips into progressiv clips.
But for some reason i cannot export them as interlaced quicktime.
I used to work with Pinnacle for SD Video. But when i started with HD, the workflow with Pinnacle was more or less like i nightmare.
So, i found a inexpensive program called Movie Edit Pro12, which makes a better job than my pinnacle. It never get stucked, streaming properly, rendering properly.
But when i go to render the Quicktime clips, the field where you can set-up interlaced or progressiv, it is freezed and i cannot change this settings.
Looks like the program is than rendering only progressiv clips.
if i render in Avi or mpeg i can change the settings, progressiv, interlaced, top or bottom field first, no problem.
All my native streaming video are streamed in as interlaced, nothing wrong with that.
Also the clip quality of the quicktime progressiv looks good to me.
Untill this Thread i did not even realized they are progressiv. I was sure that i have interlaced clips since i did not set up any settings to de-interlace my clips when rendering.
I just realized this days that the program does it by his own.

For those who are interested in why 1080p is better than 1080i:
1080i, the former king of the HDTV hill, actually boasts an identical 1,920x1,080 resolution but conveys the images in an interlaced format (the i in 1080i). In a tube-based television, otherwise known as a CRT, 1080i sources get "painted" on the screen sequentially: the odd-numbered lines of resolution appear on your screen first, followed by the even-numbered lines--all within 1/30 of a second. Progressive-scan formats such as 480p, 720p, and 1080p convey all of the lines of resolution sequentially in a single pass, which makes for a smoother, cleaner image, especially with sports and other motion-intensive content. .
On a 720p TV, that means that all incoming video is displayed at 720p (or 768p, as the case may be); on a 1080p TV, all incoming video is displayed at 1080p. The process of converting resolution is called scaling--sometimes called upconverting or downconverting. A related factor is deinterlacing (see point no. 8, below). How well a TV does or does not handle both of these processes is a big factor in how desirable it is--and something that casual shoppers often overlook, since, compared to the screen size or resolution, it's not as easy to show as a spec sheet bullet point.
Today's high-def broadcasts are done in either 1080i or 720p, and there's little or no chance they'll jump to 1080p any time soon because of bandwidth issues.
