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?

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.

About field dominance...

I just found out about setting field dominace to none and it helped a hopless shaking still that nothing else would fix. what would happen if i started a new sequence with field dom set to NONE and imported and edited NTSC DV material entirely in that sequence, or should i only use this to fix stills and do all of my editing in field dom set to LOWER? any ideas

The upside to field based render is smoother transitions, etc. Change, whether in position or speed or opacity or whatever is more smoothly rendered at 60 times a second than at 30.
But progressive (or field dominance: none) looks more like film. PLUS if you take an interlaced shot and resize it (like Picture-in-Picture) within a "progressive" sequence, you get all kinds of interlace artifacts.
So there are always tradeoffs...

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 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

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

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

Automatic Duck and Field Dominance

Hello,
Here I go again with the field dominance issue:
I am trying to import a sequence from FCP into After Effects using Automatic Duck xml import plug-in. (Highly recommend this for all FCP users who finish in AE!)
When I import the xml into AE, even if I have assigned FIELD DOMINANCE: NONE to both clips and sequence in FCP5, the footage get interpreted as LOWER FIELDS in AE.
It makes a huge difference, but I can't figure out how to import the footage into AE so that the footage can be interpreted as frames rather than fields
Thanks in advance.

You need to edit or ignore AE's interpretation rules.txt file, it is installed near the After Effects application. The user guide used to explain this, this information must have made its way out of the use guide.
I recommend you force AE to ignore the interpretation rules file. Rename it with the ¬ character in front of the name (¬ is Option-L), any file or folder whose name starts with ¬ is ignored by AE.

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.

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. 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.

Field Dominance and De-interlacing: what settings to use?

I've been trying to read about, and understand, the issues of deinterlacing and field dominance/order, but I'm having problems and don't yet see what the clear solution is.
I'm shooting DV footage with a consumer grade camcorder:
Capture Preset: DV NTSC 48 kHz
Sequence Preset: DV NTSC 48kHz
720x480 NTSC DV
QT Video Compressor: DV/DVCPRO-NTSC
The problems are "teeth and vertical lines" in the quick movements and transitions, but fixing one (by changing the "Field Dominance" setting in the Sequence) makes the other slightly worse, it seems.
Or, maybe I should be using the de-interlacing filter on everything? I haven't found clear instructions about what destination material this should be used for...
I'd be grateful if someone could look at this web page containing examples of what I mean:
http://www.karma-lab.com/images-pub/apple-q/fielddom_nt.html
Picture 1: NTSC DV frame, from sequence set to "Lower (Even)"
Picture 2: NTSC DV frame, from sequence set to "None"
Picture 3: frame from "Cross Zoom" transition in "Lower (Even)" sequence
Picture 4: frame from "Cross Zoom" transition in "None" sequence
Questions:
1) What are the correct settings? it would seem to be "None", because otherwise my transitions all have "teeth" and look like somebody is viewing it cross-eyed, even at full speed you can see the teeth in the transitions. But if I set it to none, then it seems that quick movements of the people in the videos get slightly more "teeth" to them...
2) I am producing web video (quicktime/flash video movies). Not for TV or broadcast. Am I supposed to throw the de-interlacing filter on everything?
with "lower", it's jerky (half the frames missing, I guess) but the "teeth" go away
with "flicker-free", it's not jerky, but it gets a little fuzzy looking, and I want to keep things "crisp"...
I need less advice on the theory, and more advice on "set it like this for what you are doing." I've read some really technical explanations, and I understand why interlacing exists etc., but not exactly what I should be doing to get the optimal results for my needs, i.e. simply good-looking web video with decent motion and transitions, shot from a consumer level DV camcorder.
Thanks for reading!

What are the correct settings?
Since you mention that you've shot your material on a consumer-grade camcorder, that would mean that Field Dominance – in your FCP Sequence Settings – should be set to Lower. If you use None – and I'm sparing you the tech talk here – then you're basically rendering out at a reduced quality (as the last pic in your link demonstrates)

If you really want to keep things crisp, you best quality option - within the Final Cut Studio suite of tools - is to Export Using Compressor, with the Deinterlace option in Compressor 2.x's Frame Controls to Better (Motion Adaptive) while setting your Output Fields to be Progressive (presuming that you'll exporting to QuickTime first, then converting to Flash. Having said that, this type of conversion can take a long time to process and may not be suitable if you're under a serious time constraint.
Otherwise, the speediest option is indeed to slap a Deinterlace filter onto everything (or nest your sequence then place the filter on the nest) but the quality isn't always what folks would like.

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 ?

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.

Field Dominance problem and questions

I am trying to capture 24p Advanced DVCAM material. I've been using the easy setup. I've tried test captures of about 15 seconds (using capture now) which come into FCP with a field Dom. of NONE and load into my 23.98 sequence timeline with a olive green render indicator (I know I can edit with that as that is just a playback resolution downgrade). If I rewind to approx. the same start point on the tape and capture a 9 minute clip, it comes in with a field dominance of EVEN and loads into the exact same timeline with an orange render indicator. First off, that seems odd to me. Secondly, I've read in other forums that there is a possibility that I can change the field dom. of my longer clips and/or my sequence, but I'm not at all clear on it. Will changing the field dom. allow me to edit w/o render indicators? Do you think that it is the field dom. issue that is causing the render indicators' to appear, or could it be other issues. It seems to me that the fact that I can get the short clips to load with and olive green line, means that it probably is the field dom. issue that is causing my difficulties. Is there an error in my logic? I'm also unclear if I am able to tell FCP not to render in interlaced mode. Is that something I can do? Does it even apply to my situation?

Jerry,
Thanks for the reply. I've been "assured" (who knows what that means) that the material was shot advanced, but it might make sense for me to do a test to see if Cinema Tool pulldown removal solves my problem. Can I use the pulldown removal option in the FCP tools menu after I've captured or do I need to use Cinema Tool.
I must say I'm still baffled about my different length clips capturing with different properties even though I never changed any settings between captures. Any hunches on your part about that anomaly?

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!
