1080 24p field dominance issues

I exported a project using Apple Pro Res (HQ) in 1080 23.976fps. When I take it to the dub house for mastering onto D5 tape, they tell me that the field dominance switches on several of the edits. The footage was shot on the HVX in 1080 24pa mode. Some of the dominance switches happened on edits within the same clip. Any help or cause of this would be greatly appreciated.

After testing and discussing with Apple tech, it was determined that the conversion to Apple Pro Res was the problem. I solved it by re-exporting everything in DVCPro HD 1080p24 with Recompress All Frames turned on. It's possible recompessing all frames with the Apple Pro Res would have also fixed the problem, but I ran out of time.

  • 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!

  • Exporting from After Effects (field dominance issues?)

    Hi all,
    I created a FCP DV/NTSC sequence with field dominance set to none (I'm working with still images, this improves the quality a lot). I then export that sequence as a quicktime movie file and import that movie file into After Effects.
    The problem is after I'm done working in After Effects, I can't export a quicktime file without it looking really poor quality. When exporting, I preserve all the original FCP sequence settings, except the field dominance settings(doesn't seem to be an option in After Effects for this?).
    So pretty much I am trying to get a sharp picture when exporting in After Effects, so I can take it back into FCP. Please assist.

    Your workflow is quite limited by the DV NTSC sequence. If your sequence is all stills, you are not necessarily tied to that setting at all. Do you need to output to a VTR via FireWire ultimately? What is your final output?
    A better sequence choice might be DV50. You would export a QT movie, current settings. You don't actually export from After Effects. You render by adding your comp to the Render Queue. Good render settings would be DV50 (this would not require rendering in FCP), Animation, or perhaps ProRes 422 HQ if you have access to it. You would choose not to render fields.
    If it's all stills, it would be better yet to simply start in After Effects.

  • 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?

  • 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.

  • 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.

  • 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.

  • 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 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?

  • 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. 

  • Upgrade to 10.5.7 and now i get 1080/24p on tv??

    I was hesitant to upgrade to 10.5.7 considering all the issues specifically centered around the screen issues since id already had problems hooking up my hdtv and detecting proper settings. i finally made the jump yesterday, and lo and behold , instead of my tv reporting 1080p simply, it now reports 1080/24p!!
    this is all well and good, except the slight problem, if i can call it that, is that i noticed the mouse has suddenly gotten very sensitive, even though ive notched down the sensitivity, and it seems a bit erratic.
    secondly, ive noticed when watching tv shows through my mini, i now have audio/video sync issues. i realize thats probably because the tv is now internally converting all video to 24p, while sound is still synced with 30/60hz. any idea how to fix this? the wierd thing is i can no longer find a 1080p output option, its either 1920x1080 at interlaced, which will not cut it, or 1920x1080@24hz.
    anybody else seeing this? i havent read anything about this yet.

    I am having the exact same problem, have vista/hp media center also, sometimes if I double click it will open after all, the arrow keys do navigate however, any suggestions?

  • 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)

    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 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.

  • 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.

  • 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.
