So, if the original video file is interlaced HD with upper field first (in my case ProRes 422 1080i50)), and I add to a sequence with the same settings, when I export the sequence with “current settings”, the exported ProRes 422 file will have the correct field order, namely upper field first. Right? (In this workflow I just ignore the wrong field order info in the “Item properties”? What you are saying is that there is no need to change the field order (set it to upper field first in the Browser). The file is correct, it is just interpreted wrongly and therefore displayed wrongly, but it IS correct? Forgive me for being so detailed here, but it is important for me not to end up with wrong field order, because I can’t control my exported file on an interlaced video monitor in my setup.

By “FCP sets it wrong”, do you mean that the field order is sometimes displayed wrongly, or that FCP actually changes the field order and that it therefore needs to be changed manually back to the correct field order (in my case upper field first)?
Another video guy told me that the reason that FCP (in Item properties) shows “none” for the field order, is that there is no flag in the video file that says “I have upper field first”. In this case, there should be no need to manually set the upper field first in the Browser. Or… is this necessary in order for FCP to treat the video file correctly when I add the file to a sequence?

No response – I guess the worst thing that can happen is to be alone with a serious problem – alone with the powerful and ignoring Adobe…

I can’t find any menus to set the pixels to non-square in Photoshop Elements, so I guess it will always create square pixels? Most our video editors are only allowed to use Photoshop Elements, so this is important to know. Anybody knows?

Now, this is getting quite confusing. If FCP is altering the aspect ratio automatically, what is the purpose of creating the image with non-square pixels in Photoshop? Even if I do create the correct aspect ratio in Photoshop, FCP may interpret it wrong and distort the ratio, right? Or is the clue here that when FCP understand that the file has non-square pixels, it will leave it as it is (correctly)? I presume that when FCP imports an image with square pixels, it will “distort” the aspect ratio in order to display the image correctly?

I am currently using Photoshop Elements 4.0 on my Mac, and it doesn’t seem like it is supporting rectangular pixels (can’t find any meny to choose the pixel aspect ratio – so I guess Elements always use square pixels, then?)

Here is how the video looks like at Vimeo:
You will find some details about the conversion, too.

Very nice footage! The colors, the sharpness, the composition. – About the interlaced and fast movements -discussion, as long as you follow the moving objects with the camera, you will of course have no problems. (This is also why we always follow the fast moving cars etc. in action movies, instead of standing still and watching them fly by. – Between 2:51 and 2:53 in you Flying Legends trailer, you will see the negative effect of the interlaced video if you look at the big ariplane standing in the front when the small plane (that the camera follows) is passing in the background. The plane standing on the ground would look much better if the video was shot in 50p.

OK, I respect you for your work and experience with HD, and since I’m a beginner, I will not argue. I just refer to other articles and discussions. – Maybe other user on this list want to share their view?

When you have 1080 interlaced, the vertical resolution is lower than 720 progressive, because the interlaced signal is split into 2 x half the image. So it’s a myth that interlaced 1080 is better than 720p, isn’t it? Another problem with interlaced is that fast movements will never look good, simply because the object has time to move between the first and second set of lines. This is what I have been told, and I have seen demonstrations that prove it. – There is one advantage with 1080 though, and that is the added resolution horizontally (1920 dots pr. line vs. 1280 on 720p). This is an advantage in some cases, but personally, I prefer the advantage that 50 fps gives for sports and fast movements. This is from wikipedia:
“In the USA, 720p is used by ABC, Fox Broadcasting Company and ESPN because the smoother image is desirable for fast-action sports telecasts, whereas 1080i is used by CBS, NBC, HBO, Showtime and Discovery HD due to the crisper picture particularly in non-moving shots.”
