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.

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?

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.

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

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.

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.

How to set Field Dominance

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.

Understanding Seq. Settings as Related to Frame Rate and Field Dominance

Hello All, I pondered just how to ask this question and have studied the FCP manual, especially Vol. 4
Pages 361 on. My HD project is a mix of stills and live video. The video was shot on a HV20, green
screen, captured thru an Intensity Card as Prores. (DV Matte Blast does the keying rather well).
The sequence settings are 1080i with an editing time base of 29.97, this matches the live footage. We
are getting close to the question! I noticed that I can change the field dominance to NONE, and add
my video to the timeline and still have a gray bar and good playback. I know Final Cut is doing a lot of
tricks in the background, but I would like to be sure that my sequence settings are not going to come
back and bite me
Is the net effect producing, on output, a progressive image? When I output to a QT movie I can choose
29.97 or 30 FPS. This project is not for broadcast, it will be played back off a computer, or Apple TV
in a museum setting.
I know that this is my mission, and any help in a better understanding production path is appreciated.
Thank you, Tom

Well, I was recommended to do that when using in animation.
I am very new on the AEP and FCP, so some of my friends who works on AE on PCs (I am in Brazil at the moment and few have MACs to help me)and AVID told me to change the frame rate in the composition to 60, render the 2 fields starting with lower (for TV purposes) and do the final render in 30 Frames. The reason is that the 2 fields would blend perfectly and the animation would not be shaking at the end.
Is that another simple way to do that?
I just did a test to see the final result on the DVD: got the movie with no compression and save it with DV-NTSC compression and imported to IDVD. The lines have disapeared when viewing on the play mode.

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 ?

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...)

Offline To Online Changes Field Dominance Settings?

Hi - I have an offline DV PAL sequence that I am taking online to 10-Bit Uncompressed PAL.
To my understanding PAL is Upper field dominance, and all my sequences and source files in the offline DV project are upper. However when I check the Uncompressed online project, many of the files (subclips especially) are set to Lower.
My question is this - since it's easy to change fd for clips by just right clicking in the browser, if I just set the incorrect clips' Field Dominance to Upper and make sure the shift fields filter is not enabled, can I be certain there will be no field dominance issues?
Maybe more importantly - what is the best way to determine if you have any field dominance issues? Is simply watching it on a monitor/television going to be obvious if something is wrong? Any way to check on the computer?
Thanks everybody,

Field dominance depends on the format, not the standard (pal,ntsc).
DV is lower field dominant be it PAL or NTSC, and uncompressed is upper field dominant.
For true monitoring, you'll need to view your image through an external broadcast monitor... a CRT television should be suitable for monitoring field issues (i believe... i'm sure i'll be corrected if that's wrong).
The only obvious thing to look for is 'combing'... the lines (fields) that appear around the edges of a subject on the screen, especially when there is a lot of on-screen movement.
Just out of curiosity... why are you taking a DV sequence into 10-bit uncompressed? Doing graphics etc?

Field Dominance Settings on 720p

I'm working in a 720p 30fps sequence with a mixture of NTSC, 1080i, and 720p footage -- with the majority being NTSC.
What should the sequence field dominance settings be: lower, even, or none?
The other sequence settings are HDTV 720p 16:9. Square pixels, 29.97 time base.

Despite it being early, Tony is correct. None for Field Dominance with 720p material.
Is there a particular reason you're using a custom sequence setting like that though?

Is there any way I can see field dominance?

I have been working on a project shot in HDV1080i50. Now I need to make a 14by9 PAL master in DigiBeta format. So I create an umcompressed PAL sequence and drop the final AIC 1080i50 version of the program into it.
Sending the uncompressed file off to be printed to DigiBeta the bureau says the fields are reversed. My problem is that I can't find any way to see the final project to see if I have got the field dominance right. Does anyone know of a tool that would let me look at the fields in the final Uncompressed print I generate. (when I play it on the computer screen it appears to play fine since computer monitors don't do interlaced)
thanks,

Hi Paul,
I've been battling these same issues, making DVD's from HDV footage, I didn't go via AIC, or out to a bureau, though.
I found that, the uncompressed codec, when dropped into compressor, is defaulted to a different field dominance than a DV codec, even though they were both lower field dominant in the FCP sequence.
I needed to manually change the dominance of the uncompressed movie, to lower, before I created an MPEG 2.
Can you tell the bureau to do the same ? That your footage is correct (lower first) but that they are not treating the uncompressed file as such.
What are they using, once you have given the file to them - compressor ?
The shift field filter is right. But the whole thing is quite confusing, and I found the default field dominance in compressor was different, if I printed an uncompressed file out, or exported directly from FCP to compressor (which is very slow, but does not require the uncompressed file).
However, regardless of the default compressor set, lower field dominance was correct, and the saved movie was correct for lower field.
Hope this helps.

Field dominance problem?

Hello:
When editing DVcam footage into a dv sequence with Livetype graphics, which field dominance (none, upper, lower) should be chosen in seq settings?
I take it LT graphics should be created with the same FD? Currently, my seq is LOWER fd, as are LT graphics, but this one LT billboard push transition (moves from up to down, revealing incoming shot beneath) strobes and even seems to have the "double strobe" burnt into it. I have a screen snap I could send if someone needed to see the problem.
Thanks much
KB

lower (even) is the correct field dominance for any DV based sequence (excepting HDV)
i'm assuming you're seeing this strobing on your external TV/Broadcast monitor
obviously the first thing to do is simpy run a couple of tests yourself. try changing your field dominance to None
going further, you might try using moving the whole LT compostion up/down a pixel in your FCP sequence ... its been known to help with Text Generator Crawls and Rolls.
worth a try i should think.
hope it helps
