Where do I set field dominance?

Hi,
A couple of months ago, I had edited a prgram in FCP 5. I deleted the footage after some time. Now my client has returned with some changes in the program. I re-digitized the footage & tried to re-connect it to the offline media in the timeline. However it fails to reconnect giving an error " The file does not have proper content to reconnect to " Final Edit 01" clip in sequence."
When I checked the logging info of the original clip & the re-digitized clip I found the difference in the settings of field dominance. the original is on
" Not set" while the Re-digitized is on " Even field" . I changed the settings in
" Sequence Settings" but doesn't help. Where else can I change the field dominance setting to capture the video?
Thanks.

This is the classic example of why one should NEVER load a project via Capture Now. ALWAYS mark your ins and outs and Log or Capture Clip.
That said, have you tried grabbing the clips in smaller chunks? You may find that one particular clip switches dominance and thereafter everything is switched. Try and capture the first clip only, see if it works. Then start working your way through. Otherwise, manually recreate your clips by typing in Ins and Outs, one by one.

Set field dominance

When importing SD AVCHD the field dominance set to "Un-modified" by FCP X which create a big problem when burning DVD.
is there a way to set the field dominance before importing or to set the project field dominance so every clip that go there will have the same field dominance setting?
I know you can change it after import and before editing but it's very hard in my workflow as I'm working with few different formats and cameras.
Could you do it on export clip to QT?
cheers

Why do you need to set the field dominance?
Select the clip in the Browser and choose Edit>Item Properties.
In the window that opens Control-click the item you want to alter (in the Clip column) and select from the drop-down menu.

Sorry if this is a dumb question and its one Im kind of embarssed to ask. I have final cut express 3.0 and I cant seem to figure out how to set the field dominance.

Basic Field Dominance question

In Tom Wolsky's FCE HD3.5 Editing Workshop book (xlnt), he mentions setting Field Dominance to None when working in 24p, but I'm unclear what this does and whether it applies to my situation:
I'm shooting 24p HDV on Canon HV20, exporting to QT movie, burn in iDVD. DVD to be played on generic DVD players - not going to Sundance.
Also, if I should be setting Field Dominance to None, when should this be done - before rendering, before exporting to QT, or ???

Most consumer cameras don't shoot true 24p. They shoot pseudo 24p recorded at 29.97. The material is still interlaced with a pulldown cadence. Pull the canvas up to 100% and step through the video at a point where there is some motion. If the HV20 uses the normal 2:3:2:3 pulldown you'll see a cadence of two frames without interlacing, then three frames with interlacing, then two without and so on. That's how movies are mashed onto television; four frames of film are spread over five frames or 10 fields of video. Changing the sequence field dominance to none doesn't affect the captured material in any way; it only affects how anything that needs to be rendered in the sequence is rendered. It should render it without interlacing.

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,

Field dominance tab in Browser

I’d like to see field dominance Tab in Browser. Metadata Display option doesn’t offer this item. Profissionals need see this very clear, not hidden. Thanks!

It's absolutely the right place to discuss issues. That's what user groups are all about.
What I meant was that this is not the best channel to make a formal feature request because it will go unnoticed by the Adobe team. It needs to be a formal feature request at the link I provided.
I seldom need frequent access to field dominance controls because I am usually in control of most of my source material. Occasionally I receive footage from around the world which I have to combine. I then set field dominance on an ad hoc/ trial and error basis. A simple right-click on the timeline clip suits my low-level purposes. However, material shot with one particular field dominance doesn't always "swap across" with just the flick of a switch - as you can get unsightly combing on the action.
As a work-around to your issue, can you not do a batch encoding using AME with an intermediate codec.
You must be using an interlaced XDcam format. My PMW-EX1R set to 1080p25 has no field dominance, but then I'll bet you knew that already ;-)

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.

30p with a Canon XA10 - need help with Final Cut 7 "FIELD DOMINANCE" setting and an explanation of "drop frames". Thank you!!

I shot footage using a Canon XA10 and there are issues with the HD quality not looking as crisp as it should. I am trying to make sure the settings in Final Cut are right. Need help confirming what should be in "Field Dominance" --- have seen discussions about making sure it's set to "none" but I'm confused as to what to do.
Also someone suggested I use "drop frames" to change from 30p to 24p within Final Cut. He couldn't explain how to do it so any input appreciated as well as any thoughts on whether this is a good option to try.

If you're shooting 30p, field dominance should be set to none. Since you need to use log and transfer to bring this material in to fcp, I would assume it would be set correctly automatically. Are you sure you've set the camera properly?
Drop frames will not change 30 p to 24p. Dropframe timecode simply refers to the number assigned to each frame which drops an occasional number (not any frames) so the timecode duration is the actual duration, since 30p videoi is actually 29.97 frames per second which each frame assigned a timecode number.
This is very basic video stuff and requires some basic knowledge of video. Wikipedia is a pretty good resource for much of this stuff plus there are lots of great resources on the web. Look up interlaced and progressive video, 24p and 30p.
And as far as judging quality, you can only get an accurate view of the quality in fcp when you have a video card attached to a video monitor. The viewer and canvas are only an approximation of what the quality is. Minimally, set the canvas or viewer to 100% to get a better approximation of the quality.

Which Field Dominance setting in Compressor?

Hello,
Which Field Dominance setting should I choose in Compressor, given that I shot on DV in progressive mode, and have rendered and exported to uncompressed 8-bit 4:2:2? (The Field Dominance alternatives in Compressor are: "Top First", "Bottom First", "Progressive", and "Automatic".)
I am confused by this because in FCP, I believe that the correct Field Dominance setting is "Lower (Even)" (not "Progressive"), since in DV format, images are stored one field after another, even if pairs of fields were captured simultaneously, i.e. even if the camera was used in "progressive mode".
But precisely because pairs of fields were captured simultaneously when I shot in progressive mode, I suspect that the correct Field Dominance setting in Compressor is "Progressive". But perhaps I'm wrong(?).
Would someone please enlighten me?
Thanks.
Robert

For 1080i50, you should leave field dominance at Upper. The sequence field dominance (field order is a more accurate term) should be the same as that of the source footage. Stick to that rule and you'll be OK. For progressive sources it's None. For interlaced HD format sources, it's Upper. For SD interlaced sources it's Lower.
Now, in the case of 1080p25...it's progressive, but it can be carried on a 1080i50 timeline with no ill effects EXCEPT that transitions, moving titles, and perhaps certain other effects will render with the normal interlacing of the sequence format. The fix is to change the sequence field dom setting to None. Hope that makes sense.

Field Dominance Setting question

Hi
Just read an article suggesting setting the field dominance setting to 'none' to reduce the interlace on progressive footage on renders?
I have checked the FCP manual and it doesn't specify a prefered setting for 1080i50, which I have been filming in.
Could anyone clarify or suggest pro's and con's of the field dominance settings options?
thanks

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 setting for progressive footage?

I'm still not sure about this subject.
I film with a Canon HF100. This is shooting progressive footage. I use a Imac, therefor the footage will be imported from a achvd to .mov files.
When I import it in FCE it will give automatically a fielddominance of upper odd. I heard I had to change it to fielddominace none. By mistake I edited a project without changing from Upper odd to none and there was nothing wrong with the project.
1. Is this true?
2. And why do I have to change it? What's the (technical) reason (try to understand it) and why doens't this go automatically?
Thank you!!

1) yes
2) ... field-dominance is a matter with interlaced footage ... in the older days, the many lines of a frame were splitted into two fields: even and odd lines. and funny as engineers often like to be, the odd lines (1,3,5,7,9, ... = don't neccessarily have to be the first (=dominant) field (.dv for instance: 'first' field is the even one 2,4,6,...)
progessive has no fields = no field dominance
but ..
some cams read out the chip progressive, but record the p frame as two identically i-fields! ... phewwww
summary:
if it works, don't change it ...

24p DVX footage Lower Even field dominance interlacing?

I've captured DVX 24p (not 24pA) footage. When I check Item properties for a clip FCP shows Lower (Even) under Field Dominance? Shouldn't it be Progressive or is it because 24p was captured using a 29.97 timeline in FCP as opposed to 24pA.
I am seeing horizontal lines during motion when played back on DVD? Is that interlacing? Where did I go wrong.

Look, you really need to wrap your head around 24p, 30p, 24pA and 30i.
Interlace is not an ugly issue. It is a benefit. Interlacing normal on broadcast television. Your TV scans down and back up for each frame... alternating lines. When you shoot 24p on the DVX it puts it to tape where for every 3 frames of progressive it combines FOUR frames to give you TWO additional combined (interlaced) frames. So.. there are 6 sets of 5 frames per 1 second giving you 30 frames per second. If you take those 3 progressive frames by themselves 3x6 is 24 frames per second.
You OBVIOUSLY want to final out to 29.97 or 30 fps so you'll need those extra 2x6 frames to get you to 30!! If you wanted to final out to 29.97 AND you wanted progressive frames for EVERY frame you should have shot 30p mode.
Now... when are they ugly? When you are standing still on a frame. When are they unnecessary? When you plan to show them on a computer or progressive monitor. Remember, even when shooting progressive and playing it on a TV you will STILL have the TV doing interlaced scans... the only difference is the down scan is taken from the same point in time as the up scan.
Plus... you don't capture TO a sequence... you capture the video and edit it IN a sequence. You can still capture the footage in 24p at 29.97 and remove those 2x6 extra frames and edit in a 23.98 sequence.
Do some reading. It will only help.

Working out Field dominance

I've got a sequence I'm working on where the field dominance is causing me trouble.
Essentially I've got a wide view, shot on an SD/DV camera and this is intercut with footage from a HiDef/AVCHD camera. The finished output is a DVD via iDVD and looks mostly OK (although the HiDef originated footage is far superior) but some chunks/chapters have strange double-vision/lack of smoothness which I assume is incorrect field ordering. Removing all "Shift Fields" filters seemed to help a bit, implying that the automatic calculations were getting it wrong, but I still have some bits that need tweaking.
What I'd really like to know is - is there a way of determining what the setting should be without going through the (extremely time-consuming) process of creating a DVD and looking at it on a telly?
Also, I'm not sure about the difference between +1/none/-1 (I can't believe that there can be three possible options!)
Thanks!
By the way, I don't know if anyone else has experienced this, but to get the best quality DVD from my HiDef AVCHD footage (Panasonic SD1), I find it's best to have the sequence at DV resolution (eg. by dragging some old DV clip onto it, allowing the "change to match clip" request and then removing the clip) before dragging the HiDef clips onto the timeline. I presume that what I'm doing is getting FCE to do the down-scaling rather than leaving it to iDVD - that does a somewhat poorer job.

I must correct myself: step 2. in my previous explanation is not done by FCE, which leaves the field dominance of the clip unchanged in the sequence. In fact this step is not necessary since the field dominance of the containing sequence is used during playback and export by FCE, independent of the clips dominance.
As a result also "fixing" the clip dominance, as I suggested, is not needed.
Instead adding the Shift Field filter is mandatory (and usually automatic) whenever the clip and sequence field dominance do not match.
Piero
(Alexander I agree with you: even if the section of the manual I referred is in my opinion clear, there are other sections in the same manual that are confusing: e.g. IV-388 makes statements about field dominance that seem not correct to me, mixing up the time sequence of fields and the field dominance...)

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

Where do I set field dominance?
