Field dominance. upper, lower or none?

Hi I am cutting some material in a dv pal project and am wondering about field dominance? Can someone shed some light on which is preferable for a sequence which combines material shot with different cameras, some of which having been converted in the timeline from hd to sd?
Thanks

when capturing and editing in DV PAL then choose the DV PAL Easy Setup
when capturing additional material from other sources then switch to the appropriate Esay Setup for that format.
when you mix the formats on the DV-PAL timeline, if captured correctly, then FCP will add Shift Field filters as necessary to compensate for the varying formats
when editing make sure that you are monitoring your edit via firewire (view > video playback > apple firewire dv pal + view > external video > all frames) to an interlaced monitor and not just in your canvas. in that way you will immediately be aware of any interlacing issues if they occur.

Progressive Field Dominance vs Lower Field Dominance

I am putting a project together in FCP 5.1.4 Most assets are NTSC QT clips with lower field dominance. I have some PAL assets with Progressive field dominance. I am using a slow-PAL conversion method outlined here:
http://www.macworld.com/article/49306/2006/02/marchcreat.html
I just want to make sure my workflow is appropriate.
If I use Cinema Tools to convert frame rate to 23.98 and then Compressor to change aspect ratio, and finally FCP to add frames back in to arrive at 29.97 NTSC . . .
DO I NEED TO change the progressive field dominance to lower field dominance at ay point?
I will ultimately be outputting to DVD which may be viewed on either computer or video monitor.

From my rudimentary knowledge I believe that as opposed to upper or lower field dominance, the source asset was recorded as "progressive scan", which I assume means NO field dominance.
What I do not understand is, if I import assets into a FCP sequence that has a lower field dominance, then what happens to these assets in the timeline when I export them out of FCP to either mpeg2 for inclusion in a DVDStudioPro. Or as a compressed quicktime for a streaming video on the web.
I am concerned that progressive scan assets mixed with lower field dominance may cause weird interlacing artifacts when I ultimately playback the end project.
Don't know whether I'm overthinking this, but want to avoid hours of work in the wrong direction.
Help?

Will setting sequence field dominance to "NONE" effect resolution?

First, thanks all for the title help. It looks like i might have it licked. From this point however comes a new question.
The only way to keep my titles clear and free from flicker is to set the imported livetype .mov file's field dominance to "none" and place it in a sequence that also has a field dominance set to "none". Great. now i need to put the title sequence on my master time line (project time line of 1hr 20min) which exists in a sequence set to the standard field dominance of "Lower" and which is made up of an hour and a half worth of clips that are all set to "lower" as well.
My question(s) is this-
While i understand what field dominance is doing as an upper and lower, what does none do?
Currently the project (under the settings above) is rendering as i have changed the master sequence's FD setting to none. I haven't changed the individual clip settings to none due to my ignorance on the issue, only the title sequence has the same settings. Put another way- I'm currently rendering a sequence that has its field dominance set to "none". On this sequence, i have several clips that have their field dominance set to "lower", and one clip (my livetype title clip) has its field dominance set to "none". I've done all this in order to prevent flicker on my livetype scrolling titles.
Q: Should i do this?
Q: Will i suffer a loss of resolution on the clips that have a field dominance that is different from their sequence?
Q: Will keeping them different effect the export and eventual dvd burn of the project?

Your better off NOT making a movie from LiveType, but importing the LiveType project file and rendering in FCP. Leave your field dominance settings to match your clips. If you set to NONE, that is for Progressive scanned footage. You will lose clarity on your clips. But don't just ask and listen here... do it. Change the sequence from Lower to None and look very closely at a still frame. You will see that you have lost the "jaggies" but at the cost of edge clarity.

23.98 fps advanced pulldown removel with lower field dominance??

When ever I have captured 24p advanced material shot on a DVX100B, I have always used Final Cut Pro 5's advanced pulldown removel easy set up (2:3:3:2). I haven't run into any issues until now. When I try to capture 24p advanced material, for some reason Final Cut sets my field dominance as lower (even). I made sure I was using the capture pre-set for advanced pulldown removel (23.98) and I was. Is there any way to fix this? I tried trashing my preferences but that didn't help. This is progressive scan material so in the past Final Cut Pro has always set it to field dominance as "none". Also, because my 24pa material is having a lower field dominance and as 29.97fps, I have to render in my 24pa sequence which I have never had to do. Any suggestions would be greatly appreciated.
PS: I'm using OSX 10.4.8 (the OS choice drop down menu hasn't been updated)
Update: I tried capturing a short clip (about 30 seconds) and it worked fine, but when I try capturing my clip, which is about 10 mins, I get it capured at 29.97 with lower field dominance.

Anyone ?

Field Dominance Question for Sequence

I shot my video in DVCPro50 format at 30p. I have edited my video in a DV50 sequence. I am ready to take to a production house to be transferred to BetaSP. In the past with other videos I take the finished sequence and nest it into a Uncompressed 8-bit NTSC sequence and that is what I give to production house. In this Uncompressed 8-bit sequence should I select Field Dominance: None or Field Dominance: Lower (even)?
Thanks for your help!

If someone could help me out to confirm this. I would rather do this right than find out when my commercial is broadcast that I messed up the field dominance.
My final sequence is being transferred to BETASP. I take to the production house an uncompressed 8 bit NTSC sequence.
If I understand this correctly my uncompressed sequence will have a field dominance of lower if the original footage was SD.
If my original footage was HD than my uncompressed sequence should have the field dominance set to upper.
So the uncompressed sequence that is transferred to BETASP has a field dominance set by the original footage?
Thanks for taking the time with this.

Field Dominance Settings 1080 60i

Hello -
I have footage shot with Sony HXR NX5U. Shot on 1080 60i.
What should be the Field Dominance settings be? Upper, Lower, or None?
I exported the final project to Dual Layer DVD. When people are moving hands fast or dancing. Its does not look like a smooth hand movement.
Are my settings wrong somewhere?
Thank you,

Best workflow:
export from fcp with current settings
bring this file into compressor and use the appropriate DVD preset
The smartest thing to do is a short test with a section with a lot of movement and try the 3 different options. You might also consider deinterlacing in compressor in the frame controls.

Field Dominance inconsistent after Advanced Pulldown capture

Following up on my immediately previous post (regarding the interview footage I captured from my dvx 100A using advanced pulldown setting in FCP5) I notice that, according to my FCP5 browser, some of my captured 23.xx clips show a Field Dominance of Lower (Even), while other clips show the word None under Field Dominance. Should I be concerned? And, if so, what's the solution?
Thanks!

Field dominance

Hi,
I recorded some HDV footage. It was recorded as 1080i50 with 25p.
Googling around, I found that it means its scanning the same frame twice. So there isn't a motion change between the odd and even lines.
Now the clips were captured as AIC with field dominance none. The sequence preset I used for HDV AIC is with field dominance Upper.
Is it correct that it does not make a difference whether I have field dominance set to None or Upper? None would obviously be correct as that is what the clip is set to but it should not matter, right?
thanks

I thought the field dom is simply telling which field to scan and display first (and even with none, if burning to DVD and viewing on a television, the footage will be displayed as interlaced).
Also the effect is added to clips which have field dom: none so shouldn't it be applied uniformly to the clip?
I'm a little confused.
The only effect I have added so far is smoothcam. Other than that, I have been sending to Color for grading.

Field Dominance (FCP) vs. Field Order (Motion)

I am having a time trying to figure out what's going on with my clips that I send to Motion. I'm working with video that is HDV1080i60 and has a Field Dominance: Upper (Odd). Now when I send a clip from the timeline and it opens in Motion, the video appears heavily interlaced and I have to go into Project Properties and change the Field Order: Upper First (Odd) to Field Order: None. After I make the change to Field Order: None, my slowed down wakeboarding/tubing clips look fantastic.
I don't understand why I have to make this change however. I'm sort of a noobie, learning how to apply speed changes and variable speed changes to clips. But I can also send unaltered clips to Motion and I run into the same issue.

One thing to know is that by default in FCP you are only seeing one field in the Canvas but in Motion by default you are seeing both fields - so that may be all that's going on.
To see both fields in FCP you need to set the Canvas to 100%; to see only one field in Motion, you deselect Field Rendering under the View pop-up menu (or Option-F IIRC).
When you slow a clip down, you can run into field problems, which is why choosing Field Dominance of None can be helpful. Better to work with material that was shot progressively to begin with, though.

Hdv sequence present - field dominance

Hi,
I captured HDV footage in FCE using the easy setup: HDV - Apple Intermediate Codec 1080i50. The footage was shot in PAL with a Sony HVR - 1P.
Now when I define sequences using the preset: Apple Intermediate Codec 1440x1080i50 and add the captured footage, I get a message about matching sequence and clip settings.
Turns out the clips have Field Dominance set to None and the sequence to Upper (Odd).
What do I need to go with? Keep it as Upper (Odd) or match clip and go with None.
I also dont understand why sequence preset has it set to that? I know its to do with interlacing and PAL starts at the first line. But I haven't had to do anything before with this when editing DV.
thanks

Ignore the PAL in my comment. The footage was shot in HDV and the setting on the camera was 1080i and 25fps.

Why Would Upper Field Dominance Change The Quality Of My SD So Much?

I did a shoot in SD and edited it as such of course. The thing is when I was done, all of my slow motion looked echoy (a plague of mine if you're not familiar with my posts) and generally looked a bit lower quality then even SD usually gives. So I freaked out (finally) and found a guy on line that suggested changing the field dominance to Upper and to make sure that I have my Video Processing set to "Fastest Linear". Now this was a guy that has had this posted for a couple of years, so it wasn't like he actually told me this directly.
Well, it worked. The video looks good, slow motion is nice and smooth. Just for fun, plus the fact that I don't have a clue what I'm doing, I decided to see what it would look like leaving the processing the to Fastest and change the dominance to lower, and behold, the cruddy video plague of mine returned. It seems like everywhere else I look, people say not to do this, but it worked. Why? I do know what the dominance of upper and lower are, I'm just not smart enough to know why it worked and I want to learn this badly. For example, would I do this same dominance for HD?
Thanks again guys,

I filmed it in SD on my Sony HDV-AU1 camera. What is killing me is if I choose upper then the footage looks fine, but then what I have done is add some jpeg images that I created in photoshop on a PC. they are simple images of text that say "Round 1" or "Round 2" in between the fights. I have them spin into view using one of the transitions in FCP, but when I get it to dvd, they look horrible, echoy, just like the footage looked like before I changed it to upper field. So as it looks now, I can't have both look good i guess. This doesn't make sense to me!! It is incredibly frustrating especially since I'm out of money and almost out of time on this project (it has to be done by next week). I keep re-doing the project, re-building it, re-setting it in one type of sequence after another and it's not looking good at all. what am I doing wrong?

Field dominance = NONE

Is setting my field dominance to NONE in the sequence setting going to cause me problems down the line?
I have noticed that if I do the above (after a lengthy render) the graphics I place on the timeline, lower 3rds etc created in motion, appear a lot sharper.
All the footage I edit at the moment is SD interlaced and was wondering what problems this setting might cause or if there is a different workflow I should be looking at.
All finished work is turned in FLVs for the net.
Thanks

I do de-interlace with the flash encoder afterwards as I export the project back out as a QT. The resulting 3rds are always a lot sharper from a sequence with no field dominance.
Am I confused myself or is setting the field dominance to none effectively de-interlacing?

DVCPRO HD 720p60 Footage. Field dominance set to "None" Should timeline ?

Hey all, I got some footage from a new client. I got it on a drive, so I wasnt the editor to pull it from the source tapes. Anyway, the clips read "None" for field dominance. I'm wondering if I should set the timeline sequence to "None" or "Lower" for proper playback. For output it will go to a BetaSp Deck or possibly back to the DVCPRO Deck. Lastly, the clients want to have DVD's made.
Any suggestions about the proper way to set up appreciated.

What you need to do is set the Easy Setup to DVCPRO HD 720p60...then make a new sequence...and use what settings it has. Or, if you have FCP 6, when you cut a clip into the timeline it will ask if you want the sequence settings to match that of the clip....click YES.
Since this is progressive footage, field dominance will be set to NONE by default.

Field-Dominance automatically 'Upper', how to change?

Hi!
Recently I discovered that the Field Dominance (FD) setting of my sequence/projects is automatically 'Upper'. Also when I capture from VHS, the FD of the clips in my project is always 'Upper'.
But most of the time I want the FD to be 'Lower', because I often use PAL and DV.
I've searched the Preference menu and the FCP User Manual, but I cannot find an option where I can set the FD standard to 'Lower'.
Is there such an option or do I need to change the FD manually every time?

I think so long as everything is the same field dominance and matches to your settings you're okay. The first time I came across the problem was importing DV PAL (lower ) into a sequence that was mostly SP Beta PAL (Upper) and the sequence was set for 8 bit uncompressed PAL (upper). The flickering of the DV PAL footage was only evident on the external monitor, it looked fine on the computer screen and it didn't matter how much I rendered or tried flicker filters it just wouldn't change. The only thing that worked was the Nattress "Field" plug in. It's in Filter Set 1 - http://www.nattress.com/set1.htm

Uprezzing SD to HD, make output upper field dominant?

Ok, so I'm uprezzing a SD short film originally shot on DV, interlaced, to HD for a film festival. After the uprez, the resulting file will go onto an HDCAM tape for broadcast at the fest. I want to keep the interlacing as the crappy video look is part of the story.
So, that being said, I hear all HD is upper field dominant, while my clip settings and and sequence in FCP for the original SD movie are lower field dominant. In compressor, do I want to change the settings so the output file is upper field dominant since it will be HD, or leave it as is to match the source material (lower field)? Furthermore, there are two places to set field dominance in compressor, one under the encoder tab, after pressing the "video settings" button (if interlaced is checked), and another under the frame controls tab. Do I set both to upper/lower field dominance, or is one telling it what the source footage looks like and the other is for the output file? Thanks.

OK, here you are,
