Severe flicker or interlacing artifacts with motion

In the archived topic with the same subject as this one at:
http://discussions.apple.com/thread.jspa?threadID=351090&start=0&tstart=0
my problem with interlace flicker was not solved. There is bad news and good news with the new iLife '08.
*Bad news*: iMovie HD 6.0.4 still generates flicker with the new iDVD 7.0.1.
*Good news*: iMovie 7.1 +does not+ generate flicker with the new iDVD.
This means the source of the problem was not EyeTV or its export settings, or the old iDVD. It was iMovie all along.
Of course, the new iMovie has a long way to go to catch up with the old iMovie and I seriously doubt if we'll ever see any updates to, what should I call it now, *iMovie Classic*, but actually being able to build a flicker-free movie is certainly worth something.

Interesting. I want to try the workaround ElPresidente suggested in that archived thread. Lots of good info in that thread.
I too am having this problem although I'm calling it "jitter".. See this thread:
http://discussions.apple.com/thread.jspa?threadID=1166111&tstart=0
I'm using iMovie HD and iDVD 5 and EyeTV 250 plus.
I'll follow this thread too.

  • Drawing artifacts with motion under a gradient mask

    Hello,
    I am having an issue with using a motion under a gradient mask and was hoping someone might have a solution. I have a  transparent png bubble in movie clips that are being randomly sized and  animation started using code. The design has a reflection and I am  using a gradient mask for the effect. The issue is when the bubbles  animate they are causing drawing artifacts. Please see the attached  screen shot or you can see the swf here - http://archetypeworks.com/test/tm/. Below is the code I am using to set the mask. Any help or  suggestions are appreciated.
    Code:
    bottomMask.cacheAsBitmap = true;
    beaker_bottom.cacheAsBitmap = true;
    beaker_bottom.mask = bottomMask;
    Thank you,
    Ococ

    Thank you for the suggestion, but that did not work. I also tried breaking apart the png, using the magic wand to select and delete the transparent areas. Still getting the same issue.

  • Still image with motion has flicker pulsating problem

    I use FCP 5.0.4
    I have read the many threads about this subject and am still not able to succeed in getting rid of the flicker/pulsating in a still image with motion.
    I would say about 25% of the stills with motion have the jitters; all the rest look great.
    The first thing I tried was
    Effects:Video Filters:Video:Field Shift:none
    as well as
    Effects:Video Filters:Video:Flicker Filter min, med, and max.
    Maybe 5% were corrected with this, but the other 20% still had the jitters even after using a combination of the above or by themselves.
    I just burned a test DVD using a variety of the persistently jittery stills from my current project and although the jitters change a bit, they were still there so all of these failed:
    1. Effects:Video Filters:Video:De-interlace Upper (odd)
    2. Effects:Video Filters:Video:De-interlace Flicker Filter minimal
    3. Effects:Video Filters:Video:De-interlace Flicker Filter max
    4. Effects:Video Filters:Color Correction:Broadcast Safe conservative 115
    5. Effects:Video Filters:Video:Flicker Filter max
    6. All the tricks together which means
    Effects:Video Filters:Video:De-interlace set at Upper (odd)
    Effects:Video Filters:Video:Flicker Filter max
    Effects:Video Filters:Video:Shift Fields: none
    Effects:Video Filters:Color Correction:Broadcast Safe conservative 115
    I know this issue has been kicked around a lot and i know some folks are not happy that it has to be kicked around at all. But I am doing something wrong because my DVDs look very un-PRO. Would anyone like to talk me through this nightmare preferably with as many details as possible since I am obviously missing something critical.
    Thanks in advance.

    There is no 'secret formula'. It just takes thinking through the issues.
    1. Set the image size for each image that makes sense within the context of your project. Going significantly larger than the displayed area of that image (including movement) is just asking FCP to do additional work to resize the image. FCP is less sophisticated at resizing images than Photoshop. Use Photoshop and your planning of the movie to get the images to the appropriate size.
    2. Wasted effort and totally irrelevant- you could set it to 7200 dpi if it makes you feel better.
    3. Good idea - be sure to knock down areas of pure or very bright white. These are the elements that will give you the most trouble.
    4. Don't do this unless you want to throw away HALF the picture information. Deinterlace deletes half the picture and then photoshop recreates it through interpolation of the remaining half of the picture. Why do this?
    5. Make your determination based on what works. If you have properly exposed and sized the material, the need to blur is greatly reduced. ONLY do it on the images that need it. Why degrade every image if you do not need to do so?
    6. See number 5
    7. Lay out your time line early, view the work on an external broadcast monitor and only mess about with the images that require it.
    In the psycho business they have term for much of the referenced post - it's called superstitious behavior. Basically it comes down to "It worked before so we recommend it to everyone without regard to their situation" ... here's another example:
    Many years ago in my architecture practice, we had one of the early 512k macs (upgraded from the 128k!) I needed to show one of the interns how to create a project budget spread sheet in Excel. Inadvertently I clicked on Word, said "oops", closed it and opened Excel and we went to work.
    A week later I was walking by the computer and overheard the same intern explaining how to work with Excel to another architect. "First you open Word, close it, THEN you open Excel", she explained. When asked by her 'trainee', why do you have to open Word first, wouldn't it just be easier to simply open Excel? Her answer was just perfect, "Well, it works every time, what's wrong with that?" so it goes ...
    good luck with your project.

  • 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.

  • 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.

  • 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.

  • MPE GPU renders interlacing artifacts

    I got a 60D and a Sony DV for shooting videos of some events.
    And I shot the videos using the 60D with 720p50 setting, and the DV was on 1080i50.
    What I tried to do is to produce a DVD that will have "smooth" motion instead of the 25 fps feel.
    So I drag these two file to a 50i sequence, then export it as H264 1080p25 for an hi-def internet copy.
    But I have found that the video includes interlacing artifacts in the 60d shot.
    These are the exported results that I re-import the exported video into Premiere to capture the same frame:
    And so I tried to put the videos into a AVCHD 1080p50
    which works out very well.
    Here's the problem, when I turn the MPE to software only mode...
    It does not have the problem which happened when MPE GPU Accel. enabled.
    I remembered that the problem wasn't there on CS5,
    I can mix different framerate sources in CS5 with GPU enabled but not in CS5.5 now.
    I also told a friend which have the same kind of video as mine,
    the problem is happening on his computer too.
    I wonder if this is a bug of CS5.5 MPE? or it is only happening to me and my friend?

    Setting each clip's field options to Always Deinterlace is the only way I know to get around this bug.  It works for me even in an interlaced sequence, but you said it didn't work for you.  If you haven't yet, try copy/paste into a matching progressive sequence and then set the Always Deinterlace option for the interlaced clips.

  • Interlace problems with moving objects using iDVD

    I had an MP4 file (created by a 3rd party) from a Hi-8 analog tape which has some interlace artifacts on moving images (left image of boy) but not too bad. When the MP4 files was imported into iMovie 11 the interlace artifacts smoothed somewhat - that was OK (right image of boy). The camera was still and the boy was moving.  Vertical lines on stationary objects are OK in all images. These are screen captures from the Mac of the mp4 played through quicktime and the same file imported into iMovie 11 and played.  I paused both to take the screen capture.
    The completed project in iMovie 11 looked OK when previewed prior to rendering. These are 20 year old videos so my expections were being met.   I rendered the project with iDVD to the hard drive first and then to a DVD with the same poor imaging result on the moving object.  I am using a new Macbook Pro I bought in early January which came with iMovie 11 and iDVD  Ver 7.1.2 (1158). Running Mac OS X 10.7.3  Macbook Pro  2.3 Ghz Corei7   8GB 1333 Mhz DDR3.
    I couldn't screen capture from the MAC DVD player screen to illustrate the poor result (got a checkerboard screen) so I took a photo of the screen and imported that (below).  The moving boy on the left is from an  iMovie 11 screen capture, the image on the right is the moving boy from the rendered DVD I paused on the Mac (and took a pic of).
    Below a close up of the poorly rendered moving boy viewed on the resultant DVD.  This translates into a horrible rendition of any quick moving object.  It happens with any moving image - i.e. a pan across a room with straight vertical lines like edges of a wall will show as serrated and poorly rendered edge. I used a trial version of the Daniusoft DVD creator with the same result!  I am at a loss on how to resolve this issue.  Any thoughts out there??
    I had previously used Pinnacle Studios on my old XP PC which worked great on other tape's Mpeg files and created great DVD's (never had an interlace problem) ... until my computer died .....  so I figured Apple and associated software should be at least equal if not a superior product.   Now I'm not too sure!

  • Artifacting in Motion.  Sample project, and a request for help inside.

    Would anyone be willing to download this Motion project and see if any artifacting occurs, either on playback or export? I'm on an original 2.66 quad macpro with a x1900 GPU. i've had the entire system checked out by apple, and clean installed everything and this issue still persists. i'm just curious everything the same if the issue shows up on anyone else's system with a similar configuration.
    after opening motion it takes about 2x times looped through or just randomly scrubbed before the artifacts start to appear.
    here's the link, it's got the motn source .mov zipped up and a sample of the artifacting issue as well as a screen cap from openGL monitor that shows some interested parameters jumping around when artifacting occurs.
    http://file.meyersproduction.com/motion/3.16.08/
    I copy and pasted what I sent to motion's feedback page below.
    thanks

    "issue: artifacting in motion when building/exporting multi layer projects with video with fx's and masks applied (about 13 layers with 1 mask and primatte rt turned on causes artifacting). Link to samples of .motn and .mov below.
    background: this is occurring on a clean install of os x 10.5 as well as a clean install of 10.4. this computer has spent a week at the apple store getting run through hardware diagnostics and came back with a clean bill of health. after reinstalling and building fresh projects the same artifacting immediately reoccurred.
    other notes: I have run the OpenGL monitor while playing back and exporting in motion and artifacts always coincide with a huge spike in the "Texture Page Off Data (Non-AGP)" parameter, there are also lessor spikes in "CPU wait for GPU" but those are not always indicative of an artifact.
    I also have a nvidia 7300 gpu installed and it handles any and all motn files flawlessly (albeit soooo much slower)
    I have had similar issues since purchasing this system over a year ago.
    I would sincerely appreciate any kind of communication other than "reinstall your system and FCS 2"
    below is a link to a motn project and video asset, as well as a openGL screencap and exported movie with artifacts
    http://file.meyersproduction.com/motion/3.16.08/"

    Personally, I think the problem is related to Leopard. I too have been getting artefacts in Motion 3 projects with masking since installing Leopard. Like Austin's experience, the artefacts do not appear at first after launching Motion but emerge fairly fast.
    Deleting the mask(s) gets rid of the problem but I kind of wanted to be able to use masks in my Motion projects! I had been doing so without problems in Motion 3 but with OS X Tiger. In case you were wondering, I have also reinstalled Motion and Final Cut since installing Leopard following advice on other threads.
    I don't think the issue is hardware-related, though I appreciate that my projects are very demanding for the system I have. Other more demanding projects in other applications (including Final Cut Pro) may render slowly but don't result in artefacts.

  • 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

  • Playback artifacts with MOV files from GH3

    I have successfully played and edited MOV files from GH3 on this computer, but I suddenly (End of August) started having rendering artifacts in preview, after rendering in the timeline monitor, and on export.  I've tried several different MOV files with the same issue.  I've uninstalled and reinstalled Quicktime.  When I first open quicktime after an installation, it plays the source files cleanly. But after I run Premiere Pro, I can't get clean playback in either PP or QT.  I've disabled the Nvidia Drivers for the GeForve GTX770 video card and still get the artifacts.
    Any ideas about what might be going on?

    Thank you so much for your reply.
    Yes, I have CUDA installed.  I see the artifacts in the source monitor as well as the timeline monitor.  I have tried exporting in several formats and the artifacts appear randomly in all outputs.  I can get a clean export of the same files and projects from my laptop - HP Zbook.
    Quicktime Player also displays the artifacts, but when I uninstall and reinstall Quicktime the display is clear until I try to edit again in Premiere. Then the artifacts start to appear randomly in Quicktime Player as well.

  • Video blurry with motion when trying to create WMV video to share

    I have a Sony HDR-cx350.  I am currently using PE 9.    In the past using my standard def camcorder and PE 7.0 when I wanted to share a video for online I would usually select "share - windows media" and use the LAN preset to create a WMV file that I would upload to photoshop.com and share with friends.    Now with new camcorder and PE 9.0 using these setting any motion in the video become blurry/jagged.    The only way to improve on this is to go into the advanced settings and increase the average video bitrate setting which make the file get large fast.  I dot believe I am using the best project presets to use because PE changes it for me.  But based on MEDIA info below maybe you can tell me what the best project presets would be.    Please HELP  my son's football season is starting soon and the coaches depend on me to shoot game film to share with the coaches.  TIA  FILE INFO using MEDIA INFO PROGRAM  CompleteName                     :es\DCL video 2011\20110615103137.m2ts Format                           : BDAV Format/Info                      : Blu-ray Video FileSize/String                  : 71.7 MiB Duration/String                  : 53s 14ms OverallBitRate/String            : 11.3 Mbps OverallBitRate_Maximum/String    : 18.0 Mbps  Video ID/String                        : 4113 (0x1011) MenuID/String                    : 1 (0x1) Format                           : AVC Format/Info                      : Advanced Video Codec Format_Profile                   : [email protected] Format_Settings_CABAC/String     : Yes Format_Settings_RefFrames/String : 2 frames Format_Settings_GOP              : M=1, N=30 CodecID                          : 27 Duration/String                  : 52s 986ms BitRate_Mode/String              : Variable BitRate/String                   : 10.6 Mbps BitRate_Maximum/String           : 16.0 Mbps Width/String                     : 1 440 pixels Height/String                    : 1 080 pixels DisplayAspectRatio/String        : 16:9 FrameRate/String                 : 29.970 fps ColorSpace                       : YUV ChromaSubsampling                : 4:2:0 BitDepth/String                  : 8 bits ScanType/String                  : Interlaced ScanOrder/String                 : Top Field First Bits-(Pixel*Frame)               : 0.228 StreamSize/String                : 67.1 MiB (94%)  Audio ID/String                        : 4352 (0x1100) MenuID/String                    : 1 (0x1) Format                           : AC-3 Format/Info                      : Audio Coding 3 Format_Settings_ModeExtension    : CM (complete main) CodecID                          : 129 Duration/String                  : 53s 56ms BitRate_Mode/String              : Constant BitRate/String                   : 256 Kbps Channel(s)/String                : 2 channels ChannelPositions                 : Front: L R SamplingRate/String              : 48.0 KHz BitDepth/String                  : 16 bits Compression_Mode/String          : Lossy Video_Delay/String               : -67ms StreamSize/String                : 1.62 MiB (2%)  Text ID/String                        : 4608 (0x1200) MenuID/String                    : 1 (0x1) Format                           : PGS CodecID                          : 144 Duration/String                  : 52s 487ms Video_Delay/String               : -67ms

    I feel your pain. The Adobe forum software does some odd "stuff" with formatting, and once that happens, there seems to be nothing to do about it. I have been caught in that "trick bag," more times, than I can count.
    As for Encoding to WMV, Adobe programs, are not known to do a good job of this, and that is both PrE and PrPro. For years, many users recommended Windows Media Encoder, which was free from MS, and to use that, one would Export/Share to an intermediate file, then use WME to do the WMV Encode. MS discontinued the old WME, but one user (Neale, IIRC) found a replacement. Unfortunately, I do not recall the name, but it was something like MicroSoft Media Encoder Live, or similar. That user tested the new, replacement utility, and thought that it also did a much better job, than PrE/PrPro.
    Still, quality, and especially with motion (either subject, or camera) needs a good Bit-Rate to produce good results, however at the expense of large files. As all Encoders are not created equal, the best that one can do is to find one, that does a good job, and then experiment with the Bit-Rate to get highest quality at a manageable file size. This is the same "balancing act," that we all fight with.
    Good luck, and maybe those, with better memories, can come up with the name of the MS WMV Encoder.

  • 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

  • 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?

  • 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???

    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.
