All about field dominance

i've been reading about field dominance and feel it may be contributing to my video looking crap when i play my dvd in a standard player. on some posts people recommend finding out which field the footage was captured/rendered in. how do i find this information out?

DV, DVCPRO is lower field first, anything else is upper field first

  • 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...

  • Does anyone know about field dominance?

    I just returned to Apple after a 25 year hiatus. I am trying to create my first home movie with iMovie. I have worked past the problem of importing from my mini-DVD's used by my Sony camera. However, after converting (using Streamclip) the video to a format the iMovie recognizes, my movies are 'jerky' when there is alot of motion in the frame. The movies are only jerky when played back on my television. I had this same problem while using Adobe Premiere on the PC and the solution was to reverse the Field Dominance (whatever that is). This was an issue related to the fact that my video was not loaded directly from the camera but from a DVD. Does anyone know if iMovie has the same issue? And if so, what is the solution? I have been unable to find any mention of Field Dominance in iMovie help.
    Thanks...

    NoPain.Doc,
    Welcome to the Discussions!
    I don't have a great deal of experience with it, but I think a piece of freeware called JES Deinterlacer may solve you problem.

  • 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. 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)
    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"...
    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.

  • 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?

  • 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 issue?

    Hello all,
    Working on a project in FCP. The intended delivery format is mini-DV tape. I'm working on a sequence with the following settings: (basically NTSC DV anamorphic)
    Frame Size: 720x480 NTSC DV (3:2)
    Pixel Aspect: NTSC... 720x480 Anamorphic 16x9 is checked
    Field Dominance: Lower (even)
    Editing base: 29.97
    Compressor DV/DVCPRO - NTSC (might switch to ProRes422 down the road)
    Audio is 48kHz @ 16 bit Channel Grouped
    I'm bringing in a clip that was provided by the client on a data dvds. I trimmed a section of the Quicktime movie for download available here: (~100mb, 30 sec)
    http://dl.dropbox.com/u/11697459/Trimmed.mov
    Quicktime's Inspector says the clip is:
    DV, 720x480 (640x480), Millions
    29.97
    When I put this clip on the timeline I get some nasty artifacts that appear to be interlacing issues. I was wondering if anyone has any recommendations regarding how to handle this file to improve the quality?

    Yup, that's normal DV.
    This issue occurs because of interlaced video. In your pipeline, there are 2 places that it could be coming from:
    1) The DVD that you captured this footage from already had this problem (look closely, it may not be something that you can initially see unless you frame-by-frame), which means that it was "amplified" by your re-capture and subsequent conversions.
    2) The DVD clips don't already have this issue, and it only occurred after your filtering. This is the better of the 2 for you...
    So, here's what you can do about it:
    1) "Decomb" the video. There are filters available from Red Giant, The Foundry, etc... that can take video like this and "decomb" the video. Very similar to the decomb feature found in Handbrake and other video conversion tools. You can't use handbrake because Handbrake won't give you a usable file in FCP afterwards, you need a Pro tool to get good quality results that still gives you separate Audio and Video files afterwards.
    2) Go back and de-interlace all of your source material. As I mentioned earlier, the reason that this pops up in the first place is because of the interlaced frames of video. The better option for what you are doing is to go back and de-interlace all of your source media. That will give you the best possible results for what you are going to output later on, because it's going to eliminate as much of the combing as possible before you output.
    Please keep in mind, I'm not saying that you are going to be able to eliminate this issue completely. DV is a hated format by many Pros for exactly the issues that you are facing. But, it's not your fault. Your client has made the choice, just make sure you inform them that there are drawbacks for doing so.
    Good luck!

  • Any Experts on Field Dominance?

    There are a lot of threads on these forums concerning HDV footage turning out really bad footage when outputted to DVD (worse than using an SD source). The problem seems worse for those working in PAL. Here's my theory as to why PAL users seem to be suffering with this problem more:
    HD is upper field dominance, PAL SD is lower. So a PAL based conversion from HD to SD involves resizing AND field shifting.
    If you export a HDV sequence from FCP to Compressor (using any method), then compress using default settings, Compressor outputs an upper dominance file still. This must mean DVD SP (or Toast, etc) are converting from upper to lower before it burns the DVD.
    We all know DVD SP does a crap job at compressing anything remotely hard, so why are those of us in PAL land trusting is to do field conversions? Is this conversion actually hard, or am I worrying about nothing?
    Starting out with HD definitely makes worse PAL DVDs than starting out with SD footage, so which conversion/step is causing the problem?
    If I set compressor to output a lower dominance field, the DVD ends up with unwatchable flicker in the movement, so I tried conforming the clips to a new lower dominance HDV sequence, meaning FCP is doing the field conversion. Movement is 100%, but the quality is still down a little (jagged edges). I might have to turn Frame Controls on in Compressor and let is spend 12hrs compressing a sequence already converted to lower field by FCP.
    So, I think I may have deduced that FCP is crap at downconverting. Compressor and DVD SP are crap at converting to lower field dominance. Compressor is crap at downconverting unless it's set to PAINLFULLY SLOW (ie frame controls on with Resize Filter set to better quality).
    Anyone got any comments or thoughts? Am I remotely on track or way off?
    Cheers
    Dav

    Sorry, I haven't had time to read your post carefully as I am dashing out, but I came across the problem over 2 years ago.
    Here are some notes I jotted down at the time, mainly with reference to using iDVD as the problem more or less disappeared when encoding with Compressor.
    +1. Edit your HDV/AIC in the timeline. Then create a new DV-PAL (NTSC) Anamorphic sequence. Copy your edited HDV/AIC to the new sequence. Do not alter anything. Render the sequence ..... this will take a long time - up to twice the length of the project. Then File>Export>QuickTime Movie (Not Self-contained).+
    +However, if you use the QT Movie in iDVD you will get a squashed 4:3 movie, so first of all you must make QT stretch it out to its proper 16:9 dimensions like this:-+
    +a. Open the exported movie file in the QT Pro player.+
    +b. Go to Window>Show Movie Properties.+
    +c. Select the "Video Track" and in the "Visual Settings" panel uncheck "Preserve Aspect Ratio".+
    +d. In the "Scaled Size" box set the width to 1024 pixels for PAL or 853 for NTSC.+
    +e. The "Video Track" will have turned grey, so click it to make it blue again.+
    +f. The opened movie file will jump to 16:9.+
    +g. Close it with the red button and click Save.+
    +2. This method is fast. Set your HV20 to "Locked DV" which means that FCE/FCP will capture it as anamorphic DV and edit it as standard definition anamorphic DV. (Use Easy Setup ... DV-PAL (NTSC) Anamorphic).+
    +You can then Export>QuickTime Movie to be used in iDVD and use the stretching technique mentioned above.+
    +An alternative to clicking the grey video track is to simply enter "576" in the height box and this should make the opened video file jump to 16:9, whereupon clicking the red button of the video should give you the window allowing you to "Save".+

  • FCP Field Dominance Error?  1920x1080p displayed as interlaced!?

    Can you answer this?
    Why is a video file in a 1920x1080 progressive format said to have Upper (Odd) field dominance in the Final Cut Browser, which implies that it is interlaced, not progressive?
    Here's the details.
    (A)Video shot in HDV on a Sony Z5U at 1080p30 (1440x1080) is transcoded in Compressor to Photo - JPEG in 1920x1080p30, that's 1920x1080 with square pixels with progressive frames.
    (B)The video is reopened in Compressor, which reads that it is, in fact, 1080p30 (1920x1080).
    BUT!!!(C) When the video is opened in Final Cut's Browser, it reads that it has an Upper (Odd) field dominance, implying that it has an interlaced frame.
    My Plea.
    I can't figure this out, and I need to deliver some video. I have every reason to think my video is leaving Compressor in 1920x1080p30, but the field dominance info in Final Cut is holding me up.
    If I remember right, Final Cut Studio 7 isn't able to handle 1920x1080p, only 1920x1080i and 1280x720p. Is this what's going on, maybe? Does Final Cut just not even know about 1920x1080p?
    I very much appreciate any help.

    Wow, such a quick answer and exactly what I was looking for. All problems solved and ready to deliver.
    I always assumed most programs interpreted files as they loaded them into RAM, or something like that, which is when they would determine something like if a video file is progressive or interlaced. Knowing that Final Cut, instead, looks to a table of standard values when opening a file is great to know. Thanks a lot.
    And lastly, about the sequence settings, I'm ready to deliver - the Compressor export to Photo - JPEG was the last step. I was only opening the file in Final Cut to confirm the right final format.
    Thanks again for the help.

  • 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  ;-)

  • PAL FIELD DOMINANCE

    Hi working in NTSC , I don't know about PAL, so here is my question:
    What is field dominance in pal ( upper or Lower)
    Thanks for your time
    See ya!

    Just checking archives and found a post from G Nattress
    "DV PAL, DV NTSC, DV50, DVCproHD all lower,
    HDV upper,
    PAL uncompressed SD upper,
    NTSC uncompressed SD is lower - I'd check the easy presets in FCP to be sure, although it could be hardware dependent on what you're capturing with.
    Not sure on DVD field order, but compressor usually gets it right if you tell it what the source is.

  • 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 ?

  • IDoc Error 51 - Make Entry in All Required Fields

    hi,
    I am using a scenario where an idoc is being posted into an R/3 system from a legacy application. For some reason I keep getting Idoc error 51 (Document not posted).
    Once I drill down further, the specific error states "Make entry in all required fields". Have checked to make sure all mandatory fields have been mapped and proper constant values have been specified.
    But cannot seem to get rid of the problem. Could anybody help out in determining how else to troubleshoot this and identify the possible cause?
    thx,
    Manpreet

    Manpreet,
    What IDoc Type you are trying to post ? One way is debugging the inbound function module using WE19. The second option is talking to a functional consultantor who worked, what fields are needed for that particular IDoc.
    I wouldn't care much about whether the IDoc is posted or not because, it is the ABAP ALE/EDI consultant's job to do that. The only way XI Developer is concerned is when it is not posting, ABAPer would tell what's missing.
    Hope this info helps.
