HD 24p from V1U has interlacing artifacts

I am just starting to play with my new Sony V1U. I shot a few clips at 24p and brought them into FCP. When I look at them on a 24fps, I still see interlacing on every 2 of 4 frames??
The clips themselves are still listed with a 29.97 timebase, but I can't figure out how or if I should change this. The Capture Preset is set for HDV. (There is no option for 1080p24)
Shouldn't I be able to see all 24 frames progressive in the timeline? Any ideas?

I just purchased a V1U myself. Just getting FCP 5.1.2 is NOT going to fix your problem. FCP doesn't support the V1U's true 1080 24p yet. The only HDV that FCP is referencing when you see 1080 24p is the Canon 24f thing (shutter of cam isn't true 24p, it is a software-in-the-cam solution, albeit a very convincing one...)
Anyhoo, I had success pulling the 29.97 footage down and removing the 3:2 cadence from my V1U footage. The result was squeaky clean 24p. Looks great. You'll need to use cinema tools and AIC instead of HDV (cinema tools won't let you apply pull down to frames that don't exist, so native HDV is no good; you'll need to make all your frames I frames...) I've already started using the cam's 24p scan A mode to make this easier (it resets the cadence every time you pause the camera...)
If all this sounds completely foreign to you, I advise just waiting a few months for Apple to officially support it in a future FCP release, so that FCP will remove the frames on capture.

  • Combining 24p from V1U with 24p from VX100

    As I understand it, 24p is not 24p is not 24p, and there are some issues that might arise from mixing 24p from two different brands. Is this the case? If so, what is needed to be able to capture and use the footage from a Sony 24p and a Panasonic 24P. A plug in? A setting? Hardware?

    It there/was there a problem in the past with Final Cut Pro capturing 24 P from the V1U? We had heard there was. but we are not clear what that problem may have been or how it manifested itself?

  • Interlacing artifacts on progressive footage in FCP but not when exported?

    Hey everyone! Thanks so much to everyone here who has helped me before!
    I am trying to edit a music video on my 2GHz Core2 Duo Macbook. I can do everything just fine, but with one little hitch.
    The video I am editing was shot DVCPro 1080p 30.
    When playing back the raw footage, or playing back my edits in FCP, the video has interlacing artifacts during periods of quick movement, even though the footage was shot progressive. However, when the video is exported, *there are no artifacts upon playback.*
    Also, if I open the video in Adobe Photoshop CS5 Extended, and look at the video one frame at a time, the interlacing artifacts are there!
    Anyone have any idea about why this is happening?
    Thanks so much!

    The field order of the clips are also set to none.
    Here is a picture of the item properties window of one of my main shots:
    http://gabrielredding.com/clip_info.jpg
    To make things more interesting, the interlacing follows a pattern. Three frames of non-interlaced shots, and then two frames of interlaced shots. Consistently.
    Could this have something to do with my integrated graphics card?
    Like I said, when the video is exported to a different format, the interlacing is gone, even though no deinterlacing was applied...
    Thanks

  • Trying to go from 24P DV to MPEG4 for web - Interlace artifacts!!!!

    I've tried a million different things but can't get this to work. I shot 24P (not advanced) on a DVX100. Edited everything fine, no problems. Looks great on a monitor.
    Now I am trying to export out an MPEG4 quicktime for the web. I get interlacing artifacts. I tried using Compressor and exporting from FCP and Quicktime Pro. I tried doing a reverse telecine in Cinema Toolsat 24FPS which seemed to create a DV quicktime without the 3:2, but when I try to convert that file to MP4 the interlacing problems reappear.
    What am I doing wrong? What can I do? Help is appreciated!

    Yes, but Cinema Tools removes the pulldown based on timing - like removing every fifth frame. If the movie you feed it is made up of a number of clips with different cadences, Cinema tools will pull the wrong frames out of some of the clips. That's why I said it needed to be done on a clip by clip basis.
    Does this make sense?

  • INTERLACING ARTIFACT promblem on DVD burn from HD uncompressed clip

    Hello,
    I'm trying to export a long feature film that has been exported from After Effects to HD uncompressed 10-bit in HDTV (rec. 709) color space, 1920x1080, 29.97.
    The original footage was ProspectHD 10-bit digitized from HDTV tapes shot using SONY HVR-Z1U.
    The HD clips are flawless, I use them with a Dolby Digital Surround AC3; there 6 clips lined up, since putting all together makes for a to massive clip to handle smoothly.
    Encore takes about 40 hours to re-encore to burn it to either a blu-ray or DVD.
    The result is ok in most of shots, but when action get quicker or camera jerkier or fades are involved; then, I get interlace artifacts, I see unsynched fields effets where lines aren't lined up properly.
    Sometimes it goes as far as a region on color  (like a sky) falling appart for a few frames; in fades mostly, but not mostly.
    I've seen many stuff on this forum about interlacing problems, but nothing I could tie down to my exact problem...
    Should I pre-encode my clips to mpeg2 DVD ready before doing the burning ?
    Should I deinterlace them ?
    If I do deinterlace them, wouldn't this affect synch with audio clip ?
    What about the deinterlace button option in Encore ?
    If I pre-encode (deinterlacing or not) before burning, won't Encore recompress it when burning DVD ?
    If it does wouldn't I loose quality this way ?
    To stop this, can I do lie I did for my already encoded AC3 audio track ; mark clip as "do not re-encode" ?
    Thank you.
    Sincerely,
    Frédéric

  • Interlacing artifacts / jagged edges

    Hi,
    I've read many of the posts on the Apple Final Cut forum and elsewhere about interlacing artifacts in video. For background info, I'm working with a client's SD DV footage (16:9). It was shot on mini-DV @ shutter rate 125. (BTW, completely white background with people wearing black shirts doing exercises.) The footage is in FCP now and has noticeable interlacing artifacts especially with faster motion and around object edges (black shirts, etc.). I believe that my sequence settings are correct:
    720x480 NTSC DV (3:2)
    Pixel Aspect Ratio: NTSC-CCIR 601/DV (720x480) - Anamorphic checked.
    Field Dominance: Lower (Even)
    Editing Timebase: 29.97
    Quicktime Video Settings:
    Compressor: DV/DVCPRO-NTSC
    Quality: 100%
    Advanced:
    Compression Type: DV/DVCPRO-NTSC
    Frames/Second: 29.97
    Compressor: Best
    Scan Mode: Interlaced
    Aspect Ratio: 16:9 (was 4:3, changed it to 16:9)
    When I encoded a test sequence in Compressor (using best quality, 16:9, 2-pass at 4.2 bit rate), the interlacing artifacts in the encode came out even more slightly pronounced. I also opened this mpeg-2 in QT Player to verify that the artifacts were true. This project is going to DVD (using DVD SP to author, Compressor to encode) for TV and computers.
    As I mentioned, I have read varying information/opinions about interlacing issues and how to resolve them. One mentioned that it has to do with the computer monitor, and that the DVD wouldn't show interlacing artifacts when played on TVs . The other list of possible resolves I've found are:
    1. Add motion blur filter
    2. Add de-interlace flicker filter
    3. Add Stibb's De-Interlacer filter
    4. Add field interpolate filter
    5. Change motion estimation in Compressor from better to best
    6. Try changing field dominance from bottom first to none
    Is there anyone who has expert experience with this issue - who has run through different fixes for this issue and can tell me what works the best? Thank you in advance.

    Best way? Or best way with tools you have access too?  Best way is via a hardware converter called a Terranex or Alchemist.

  • De interlace artifacts

    I am working on a FCP project with settings at Pro Res 422.  Footage shot at 1080 24p, imported from P2 card.
    When i idrop footage into seqeunce, it tells me seq set and footage don't match, so i say yes change settings to match.  So my footage with movement , small hand movement shows deinterlace atrifacts. So I tried another seq. and said no leave seq at setting I have chosen, artifacts still there. 
    I have had this when using pro res setting, solved by using apple intermediate codec....is pro res better, I thought so , or should I just use the apple I codec.
    When dropping a deinterlace filter on I beleive one loses quality.
    Please help??? 
    Catherine

    P2...what format? DVCPRO HD or AVCIntra?  DVCPRO HD comes in as DVCPRO HD, and AVCIntra by default comes in as ProRes. 
    But, P2 cameras don't shoot native 23.98 at 1080p. They only shoot that with 720p, on a setting called 720p 24pN..."N" meaning NATIVE.  At 1080p24, the camera shoots the 24p look, but in a 29.97 frame rate...so there will be interlaced frame blending.  There are two styles of 1080p 24 it shoots...1080i 24p, and 1080i 24pA. 24pA, "A" meaning "ADVANCED PULLDOWN," can be imported into FCP and have the pulldown removed so you end up with 23.98 files. BUT, if you shot 1080i 24P...regular 24P...this won't happen, and you'll have the 24p look, but at 29.97fps.
    And the reason you see these interlaced artifacts is that computer monitors don't show interlacing well.  To really see what your footage looks like, you need a capture card, output device (AJA, Decklink, Matrox) and an HDTV.

  • Capturing 1080p 24p from p2

    I have received a drive with footage that was shot on the Panasonic HVX200 with P2 cards. After speaking with the DP, the format of the footage is DVCPro HD 1080p 24p (not 24pa). After performing the Log and Transfer, when I look at the clip I see 3 progressive frames, then 1 interlaced frame (repeats).
    Page 66 of the manual for working with FCP & HD video indicates
    To remove standard 3:2 (2:3:2:3) pulldown from 1080p24 footage, you need to
    capture the footage as 1080i60 (29.97 fps) and then use Cinema Tools to remove
    the pulldown.
    Page 100 indicates:
    The Import Panasonic P2 window cannot remove standard 3:2 pulldown.
    To convert footage with 3:2 pulldown, you can ingest the media at 29.97 fps and
    then use Cinema Tools to remove the pulldown.
    Page 103 indicates:
    Use Remove Advanced Pulldown command in Final Cut Pro or Cinema Tools after capture or ingest.
    I am familiar with Cinema Tools, and have performed the conform process before with footage from the HVX100 in Standard Definition with no problem. However, when I attempted to remove the pulldown in cinema tools, the footage appears unaffected even though the frame rate is now 23.98.
    I read in another manual "Workflow for Final Cut Pro and the Panasonic AG-HVX200"
    that 1080p 24 is Not supported at this time.
    Has anyone had success capturing 1080p 24p from a p2 card and then removing the pulldown to get 23.98 with progressive frames?

    Just to make sure, since you mentioned advanced pulldown. You should be removing regular pulldown, not advanced pulldown. Also, conform is for files that are already progressive. What you want is reverse telecine. Try doing a batch reverse telecine on a few clips. I've had problems in the distant past doing it on single clips because I wasn't starting with an A frame.

  • DV-avi h.264 causes interlacing artifacts

    For days now I've struggled with this problem. The dv-avi to h.264 convertions -always- have the following problem: Sideways motion looks very bad since there are very noticeable interlacing artifacts (i.e. combing effect). (Although if I use de-interlacing during the conversion the effect is different: in sideways motion the combing effect is not present but the vertical lines flicker.)
    I have a Sony SD mini-dv camera DCR-HC42E PAL. The footage is in 16:9. I've captured the material using Adobe Premiere Elements 3 (APE). The camera is connected to pc via Fireware. To do the conversion I've tried many programs such as:
    - APE
    - MPEGStreamclip
    - QuickTime Pro
    - Videora
    - Nero
    (Perhaps it is worth mentioning that Using APE and Nero I have not succeeded in producing a file that is playable at all in ATV. Maybe I just don't know the correct settings.)
    The dv-avi file looks ok in Windows Media player. In QT pro there is already the combing effect even before the conversion.
    The QT Pro (window > show movie properties) shows that the size of the dv-avi file is 768 x 576. Windows Media player (> file > properties) shows that the size is 720 x 576. Windows Media player also shows that the aspect ratio is "4:3 actual, 16:9 displayed".
    Í've tried
    - different output resolutions (unscaled, 1024 x 576)
    - different bitrates (1500 kbps, 3500 kbps)
    - with and without de-interlacing
    - field dominance lower and upper
    - multipass, b-frames
    - apple tv presets (QT pro, Videora)
    If I just export the dv-avi to standard dvd, the result is good (no interlacing artifacts). But I'd like to use ATV to watch my mini-dv footage.
    The media is synced in ATV. The ATV is connected to a Pioneer 436 XDE plasma (HDReady, panel resolution 1024 x 768) via HDMI.
    I am beginning to think that either the Sony camera does not produce the right kind of dv-avi or it simply is not possible to have a decent dv-avi pal > h.264 conversion. Any help is greatly appreciated.

    The dv-avi file looks ok in Windows Media player. In QT pro there is already the combing effect even before the conversion.
    If you select show movie properties from the window menu in QT then select the video track and visual settings then checking/unchecking Single field/Deinterlace should show you an immediate effect, you can also opt to scale your video to 1024 x 576 here, you can then choose to save your changes. You may find the actual conversion to AVC is then better done in streamclip. I too have this interlacing issue when converting homw movies to AVC, being on a mac my workflow is to import and edit in imovie, export to full quality and convert in streamclip (actually I don't export to full quality, imovie creates a reference file as you edit which streacmlip can use to convert - I'm not sure which other programs do this though, so exporting or saving to full quality might be your only option).
    These are my streamclip settings
    Are you sure you are suffering from interlacing and not field switching, the effects can seem similar.

  • Photos and aliasing/interlace artifacts

    Well, i'm dyin' here, and need a life because i'm posting on christmas eve, but here goes:
    all i'm trying to do is rotate a still image (pict file) about the Y axis (left to right rotate, not top to bottom) over a moving background, and at the 90 null point, rotate another pict back around on the other side. simple move. i have a beveled border around them and they are squeezed down to about 80% of normal size. i have about 2 dozen of them to do.
    i'm getting TERRIBLE interlacing artifacts on the edges of the picture. i have put the de-interlace filter on them, and the flicker filter. i'm using the "basic 3d" filter to effect the y-axis rotate. i've tried the anti-aliasing filter, but all it seems to do is soften the pict file. i attempted to add a motion blur filter, but the render time seemed unreasonable.
    i'm using FCP 3.0.2 on a single proc. G4 450, with os X.3.9.
    ANY help you can give me would be appreciated.

    I have no idea why FCP can't handle motion really well, perhaps it is simply to force people to use the app MOTION. Since I was an AE guy, I choose to these sorts of things there.
    You've already done the basic things to the images and I can't offer you any more than good wishes and the hope you can learn new software quickly. Sorry.
    Good luck.

  • Interlacing artifacts

    When importing from my AVCHD camera into FCP (using log&transfer) I can see the interlacing very clearly when looking at the .mov files in quicktimeplayer (viewing in fullscreen).
    Is it something I can do in FCP to get rid of those interlacing "artifacts"?

    your computer monitor is not an interlaced display.
    what is your target delivery format? are you intending on delivering as quicktime movie files to be watched/played fullscreen on a laptop? if yes, then you probably do want to remove the interlacing ... but if you intend to deliver for broadcast or DVD to be watched on a TV, then you probably don't want to remove the interlacing at all.
    there is a tendancy at the moment amongst many folks who simply don;t understand the nature of the formats and delivery mechanisms they are working with, and it leads to a lot of misconceptions about what plan of action should or should not be undertaken to get the "best" results.
    question: would you class yourself as a hobbyist working with pro-software, or would you say you were a pro working with pro-software. in either case, but much more important if its the latter, you should invest in some time, money and energy in learning about your profession/hobby (and thats not just by asking questions on internet forums as useful as that is, but also by buying and studying reference books, enrolling in classes etc)

  • Should I switch back to imovie11 from FCE4? Interlacing issues 1080i

    Hi.
    I shoot in 1080i50. I use FCE4, export quicktime movie and burn using Toast on dvd with BR option. When I play the dvd on my Blue Ray player, the video looks stunning on my TV.
    I am wondering, if I buy imovie 11, import 1080i, and export it at 1080, burn it using Toast. WIll I get the same results as when I use FCE4, or will I have problems with interlacing artifacts? (I had those problems using Imovie 09, and that was one of the reasons why I switched to FCE4)
    I would really like the simplicity of Imovie, but not at the cost of quality loss.

    I am getting really good results from 1920x1080i source and sharing to iMovie 1080P. I need to do some more testing to be sure. I have not tried Toast BluRay yet.
    By the way, a 4 minute iMovie project takes about 1 hour to render in 1080P on my 2.8ghz iMac. So you can see why testing will take a while.
